2.1.7 Energy-saving And Environmental Protection Measures
(1) Energy-saving measures
The parameters designed indoor meet the requirements for the energy-saving of
residential building. The pipes insulation material and insulation thickness meet the
related requirements of the energy-saving of residential building. Self-operated
pressure control valves are set at the thermal entrances, which enable the secondary
network system to achieve variable flow conditions to run. The indoor heating system
adopts household metering and sets the sub-room temperature control and automatic
adjustment device. The performance parameters of insulation materials meet the
energy-saving standards.
It's suggested that the substation be set in the electricity load centers in order to
control the distance of the 0.4kV supply-lines in the project, and to reduce the line-
losses. The high light efficiency energy-saving lighting products and supporting low-
power high-performance energy-saving electronic ballasts can save about 20% of
electricity than the inductance ballast. The motor, inverter, and electric equipment

about 30000 kWh. The solar lamps and LED light source are adopted in the street.
Compared with the other light sources in the same luminous efficiency, the energy-
saving rate of the LED light source is 75% ~ 80%. The solar collector panels are set
up on the roof panel, and the tap water is sent to every household after heating.
The implementation of electrical equipment energy-saving control: according to the
different functions of the rooms, equipped the corresponding lighting control; the
living water pump, heat pumps and other equipment are equipped with frequency
control devices; the garage is designed with natural ventilation.; while no passenger in
the elevator, the lighting, fans stop working, and automatically activate as being
called; establishing energy consumption and water consumption statistics and
management systems and automatic measurement management.
(2) The main water-saving measures
Make full use of the pressure of municipal tap water, use the municipal pipes and
networks to directly supply while meeting the water pressure, use water tanks and
water supply installations VVVF to pressurized water supply while not meet, and use
constant pressure variable to save electricity.
The water saving apparatus is adopted as the sanitary apparatus: the water closet,
with two trenches of water, the flushing water volume of which is no more than 4.5L;
adopt ceramic to seal taps; adopt high tightness valves in water-supply and reclaimed
water system, the core and stem is made of copper material, while the body ductile
cast iron.
The water-supply branch pipe pressure of residential household is limited between
0.07 and 0.2Mpa. While the branch pipe pressure is more than 0.2Mpa, the pressure
reducing valve is set.
The entire water-supply system is monitored by central management to prevent the
overflowing of the pool and not timely processing, and to maintain the pump normal
operation.
(3) Major environmental protection measures
15
The clean energy natural gas is selected uniformly as the gas. Reduce the private car
to be used. Advocate walking, cycling, public transportation and other green
transportation modes.
Make the rainwater and sewage diversion. Promote residents to use reclaimed water,
rain water and other non-conventional sources. After pretreatment in septic tanks, the
wastewater is discharged into the municipal sewage pipes.
Use the pump as damping foundation. Set metal-based soft-pipe connections in the
import and export; use the pipeline in the pump room as the damping hanger. Equip
the damping facilities with fans and said unit. Hoisting installation of equipments
adopt elastic suspension.
The garbage are collected into different categories: Metal, glass waste and toxic and
harmful, large garbage are classified and stored in designated place, coped by the
relevant authorities contacted by the property management company. ; kitchen waste
and other refuse are sent to garbage collection points through the pneumatic
conveying system from the garbage embarking ports at different times, and then
removed and transported by a sanitation vehicle.
The basic plan about school Pilot Project is as follows: Covers an area of 3.55 hm2,
total construction area of 19,198 m2; Constituted by the teaching area, administrative,
sports and living areas, which include classrooms, laboratories, conference rooms,
offices, libraries and sports centers, stadiums, canteens and so on, housing 1620
students. The environmental impact of the project is little. It’s just need to fill an
environmental impact registration according to "construction project environmental
impact assessment classification management List".

2.2.2 Sources of pollution During Construction Period
The main environmental impact of the project during the construction period is the
atmospheric dust pollution, mainly from the following aspects:
land leveling, earth excavation and earthwork stacking
construction materials (cement, lime, sand, etc.) handling, stacking
construction waste dumping and clean-up, transportation
the rolling and taking etc. of people and vehicles
The output and impact of dust is related to the type and the nature of the building
materials, the construction mechanization, the management level, the weather regime
and some other factors.
The noise during the construction period is mainly produced by the bulldozers,
excavators, mixers and other machinery, equipment and transport vehicles in the
process of site clearance, excavation, material transportation, piling, drilling, etc.
In addition, there are construction waste such as concretes, waste soils, waste fitting-
up materials, and a small amount of domestic sewage and garbage generated by the
constructors.

2.2.3 The Pollution Sources during Operation Period
The atmospheric pollution source includes emissions from burning natural gas, and
car exhaust during operation period. The former main pollutants are dust, SO2, NOx,
etc., and the latter main pollution components are CO, NOx, and THC (total
hydrocarbons), etc.
The main water pollution during operation period is the domestic sewage generated
by living and public buildings, the main pollutants of which are BOD5, CODCr, SS,
ammonia nitrogen, total phosphorus and so on.
The noises during operation period are from the living of residents, water pumps, auto
and other sound sources. The main solid waste is solid waste, including scrap metal,
glass, plastic, paper, kitchen waste and other ingredients.

3 ENVIRONMENTAL BBASELINE INVESTIGATIONS AND
ASSESSMENT
3.1 PROFILES OF THE NATURAL ENVIRONMENT
(1) Location
The project is located in Block No. 15 of Sino-Singapore Tianjin Eco-city. The Site
Selection Program is located in the waterfront leisure and tourism area determined in
the overall planning of Tianjin Binhai New Area. It's located in the east of the Jiyun
and the Yongding New River Interchange to the mouth, including 2 parts of Tanggu
District and Hangu District. The location away from the core area of Tianjin Binhai
New Area is about 15km, from the central city is about 45km, from Beijing is about
150km.The transportation is convenient, and the location advantages are obvious.
18
(2) Topography and landform
The landscape of Hangu and Tanggu District where the project is located is was
formed in the process of the Holocene sea-land retreating and evolving. The alluvial
plain of marine was formed 1500 ~ 3000 years ago, the sea alluvial plain 700 ~ 1500
ago, and the inter-tidal beach has been in the formation of the gradual siltation sin 700
years ago.
The Eco-City is located in the crust-sinking strongly region. The Jiyun River is one of
the rivers into the sea. The typical plot of marine plains and alluvial plains of the sea
are shaped in the interaction of the rivers and ocean dynamics. The main topography
of the planning area is constituted of muddy beaches, coastal lowlands, latent dish
depressions, plains, flood land, etc.
This region is the northeast of North China Plain, with low-lying terrain, elevation is
bellow 5m (Take levels), most below 3m, with little ups and downs of the ground,
slope of 1 / 10000 ~ 1 / 5000, slightly higher of north and lower of south. Overall, the
features of the regional landscape are as follows: the late formation of the landscape,
the vast plains landscape, magnanimous low-lying terrain, numerous canals and
Wadians.
(3) Hydrology
The major river in the eco-city area is Jiyun River, which flows from Tianjin Ninghe
County through downtown and YingCheng village to Tanggu District, and ultimately
goes into the sea from Beitang mouth.
(4) Geothermal resources
The project is located in the northern of geothermal field in BinHai District. The
underground hot water is mainly conferred in Neogene in Minghuazhen heat reservoir
layer and Guantaozu heat reservoir layer on Tertiary system.
A Minghuazhen heat reservoir layer on Tertiary system
The average depth of the roof of the hot reservoir is 450 ~ 600m, and the average
thickness is more than 500m. It's divided into the upper and the lower of
Minghuazhen. The lithology of the thermal reservoir: the upper is composed of 4 to 6
sedimentary cycles; the interbedded thickness varies between pink semi-cemented
fine-grained sandstone, fine sandstone and variegated mudstone; the total thickness of
sandstone is less than the mudstone's. The lower is mainly Mudstone, mixed with
19
powder fine-grained sandstone; the lithology of the bottom is gradually thick, mainly
brown-red, brown-yellow, mixed with dark gray, gray-green, somewhere with sandy
strip, common with gray-green spots and stripes. The water consumption of single
well is generally 40~ 80m3/h. The temperature of well mouth is 40~ 60℃.The
chemistry type of water is HCO3-Na, HCO3·CL-Na, the individual lot is
HCO3·Cl·SO4-Na. The salinity is 0.85 ~ 1.8g / L, and total hardness is 10-60mg / L.
B Guantao heat reservoir layer on Tertiary system.
The depth of Guantao heat reservoir roof is 1200-2400m, which is a fluvial clastic
deposition, mainly thick-thin-thick sedimentary cycles, that is, the bottom with the
sand-conglomerate section, the central section with mudstone and the upper part with
sandstone. According to this stratigraphic feature, the thermal reservoir sandstone
section can be divided into Guan I and Guan III sandstone heat reservoir sections. The
lithology of the thermal reservoir is poor, loose and porosity. The water yield of single
geothermal well is 80 ~ 120 m3 / h. The temperature of well mouth is 65 ~ 87 ℃.The
water chemistry type is mainly Cl • HCO3-Na, with salinity of 1.5 ~ 1.8g / L, total
hardness of 30 ~ 110mg / L.
C Mineral water
The mineral water resource in this area is the by-product of the underground hot
water, with basically the same hydro-geological conditions with the underground hot
water. The mainly type of mineral water is metasilicate type. Its content is closely
related to the temperature of groundwater. As the general groundwater in the region
for each additional 10 ℃, the content of SiO2 in water increased by about 5.9ppm.
According to the analysis results, the content of silicate is more than 37mg / L, while
the metasilicate acid content of underground hot water in Guantao group can be
greater than 50mg / L, reaching standards of medical mineral water. In addition, the
mineral water also contains lithium (Li), strontium (Sr), zinc (Zn) and other beneficial
trace elements. The fluoride (F) content of underground hot water is more than the
national standard for drinking mineral water, so which can be used as drinking
mineral water after fluoride removal treatment.
(5) Weather and climate
The eco-city is located in the western of Bohai, controlled by the monsoon circulation.
The climate is warm temperate semi-humid continental monsoon climate, four distinct
seasons; drought, windy, cold , warm and changeable in spring; heat, moisture, rain-
20
concentration in summer; crisp air in autumn; cold, snow-less in winter. The annual
average temperature is 11.7 ℃, highest in summer is 39.9 ℃, lowest in winter is -
18.3 ℃. The average precipitation is 588.2mm.The rainfall mostly concentrated in
July and August. The average annual evaporation is 1750 ~ 1840mm, as 3 times of the
precipitation. The annual average sunshine is 2898.8 hours. The average percentage of
sunshine is 64.7%.The annual average wind speed is 3.6m/s. Northwest wind is the
most from every January to March, while southern from April to June, the east wind
from July to September , the Northwest wind and southwest wind from October to
December.
The air temperature in spring rose rapidly, with changeable, dry, windy, longtime
sunshine, and evaporation. The average precipitation in the full-season is 63.4mm,
accounting for 10.8% of annual precipitation. The average wind speed of quarter is
3.7m / s.
The temperature in July is the highest in summer, with extreme maximum temperature
of 38 ℃.Because of the warm and humid air mass from the Pacific, the southeast
wind is prevailing. The average rainfall is 434.8mm, accounting for 73.9% of the
whole year. The average wind speed of quarter is 4.3m / s.
The temperature drops significantly in autumn, with more sunny, small humidity,
abundant sunshine and pleasant weather. The average rainfall is 76.9mm, accounting
for 13.1%. The average wind speed of quarter is 3.0m / s.
In winter, it's dry and cold, with less snow, northwest wind prevailing, windy days of
8.3 days, second only to the spring, with an average temperature of -3.1 ℃, annual
precipitation of only 13.1mm, accounting for 2.2% of the whole year. The average
wind speed of quarter is 3.3m / s.
(6) Environmental geology
There are land subsidence problems in the area of eco-city. According to the
monitoring, the amount of precipitation in Hangu district reached 50 mm/a in 2003.
The factors affecting land subsidence can be summarized into two categories: One is
natural factors, including seismic activity, the movements of crustal movement, as
well as the settlement resulting from the natural compaction of stratum; the other is
man-made factors, including the exploitation of underground water, underground hot-
water, oil, gas, construction of underground works and other types of loads on the
21
earth's surface. The land subsidence in the region is mainly related to groundwater
exploitation and the natural consolidation density of stratum.
(7) Soil
Soil in this region has developed from the soil parent material of sediments in sea and
river. It contains more than 45% physical clay with less than 0.01mm, which is heavy
and light clayey loamy soil. It also shows characteristics such as bad soil structure,
high bulk density, less non-capillary gaps and poor permeability. According to the soil
analysis of soluble salts, the soil in western region is re-saline soil, which soil salinity
is generally 600 ~ 2000mg per 100g soil samples, and the main types are wet
saliferous clay, marsh seashore saline soil, and seashore saline soil. The degree of
salinization is sever and has already had significant impact on the plant. The eastern
region is saline soil area, in which soil salinity is generally more than 2000mg per
100g soil samples, and the main type is seashore saline soil. Soil in this region is not
suitable for plant growth.
3.2 PROFILES OF THE SOCIAL ENVIRONMENT
The planning area of Sino-Singapore Tianjin Eco-city belongs to Tanggu District and
Hangu District and the total area of it is 34.2 km2, among which 2 / 3 from the Hangu
area site and 1/3 from the Tanggu District. There have been three natural villages
(Dongfeng, Wuqi, and Qingtuo) here before, with1526 people. The relocation of their
resident population has been basically completed.
Sino-Singapore Tianjin Eco-city is a strategic cooperation project between China and
Singapore. According to The General Planning of Sino-Singapore Tianjin Eco-city
(2008 ~ 2020), Eco-city will be built into “a platform for the technological innovation
of eco-environmental protection, energy-saving emission reduction, green building
technologies and so on in China; a national center for environmental education
research and development as well as communication and exhibition; a eco-industrial
base and a window for participating in international eco-environment development
issues; a new town with demonstration of ecology and suitable for living”
The space structure of eco-city can be described as "one chain link of one nuclear, 6
wedge-pass river and sea, an axis through four areas", with making use of appropriate
multi-scale organizing groups layout: in each piece area, public service centers are
located in the center of the area, with residential land around, and commercial
industrial land is arranged at the edge of the area, closes to the road outside the
22
region; professional services are arranged in the ecological distribution of nuclear and
ecological chain. The project site is located in district No. 15, eco-city start-block, and
southern comprehensive area of residential land.
The population scale of eco-city is planned to be controlled within 5 million people in
2010, within 20 million people in 2015 and within 35 million in 2020. Leading
Industries of Eco-city are eco-technology research and development (conversion)
industry, environmental protection education industry and green building industry,
ecological emerging service industries. The expected job provided in 2010 is about
30,000, in 2015 is about 150,000 and in 2020 is for about 210,000. The local
employment rate should reach 65%.
(2) Land utilization.
Most of the land within the south of Sino-Singapore Tianjin Eco-city planning land is
the salt fields and fish breeding ponds, the center of planning land is mainly
composed by wasteland and reed marshes. The land surrounded by old Ji canal river
contents Hangu sewage library, golf course and surrounding villas, in the north is a
village called Dongfeng Village, and the western land of this village contents small
vineyards and other agricultural land and reservoirs. The project site is flat land and
prepared for the construction.

The project is located in the Tianjin Eco-city new zone where there has no surface
water bodies, the project site is currently flat land which is waiting to be built and no
adverse ecological problems exist.
4 COMPARISONS AND ANALYSIS OF ALTERNATIVES
4.1 ANALYSIS OF NON-PROJECT ALTERNATIVE
(1) By Project Non we mean that this project will not be carried out. In this project,
because of the soil salinization, there are no large areas suitable for vegetation growth,
maybe except for a small amount of salinity plants; in sandstorm dust season, it may
become sources of pollution, and in the rainy season it is prone to soil erosion; water
supply and drainage, gas, transport and other infrastructure is seriously lagging
behind, the residents are poor, low-income and their living conditions are unable to
meet the positioning of Sino-Singapore Tianjin Eco-city that to become “a platform
for the technological innovation of eco-environmental protection, energy-saving
emission reduction, green building technologies and so on in China; a national center
for environmental education research and development as well as communication and
exhibition; a eco-industrial base and a window for participating in international eco-
environment development issues; a new town with demonstration of ecology and
suitable for living”.
(2) By Project Scheme we mean that the scheme will be implemented in this project.
25
After the completion of this project, through the appropriate adjustments to the soil
surface to enhance green building (green land reaching 40%), it can increase the local
biomass and bio-diversity; to improve the green sand can also reduce dust pollution
caused by soil dust; the rapid establishment of infrastructure such as water supply and
drainage, gas, transportation, can not only improve the living conditions of residents,
but also help to increase people's income, to solve the housing problems of low-
income people and therefore have good social and economic benefits. At the same
time, in the planning, design, construction and operation management of the entire
process of the project, it focuses on green building requirements, adheres to green
construction, and can effectively control the air, water, noise, garbage and other
effects of the construction, environmental protection and conservation of water,
energy, land and materials can be used as application platform of related green
technologies, therefore becomes a good model and also meet the positioning of Sino-
Singapore Tianjin Eco-city so as to become “a platform for the technological
innovation of eco-environmental protection, energy-saving emission reduction, green
building technologies and so on in China; a national center for environmental
education research and development as well as communication and exhibition; a eco-
industrial base and a window for participating in international eco-environment
development issues; a new town with demonstration of ecology and suitable for
living”.
4.2 THE COMPARISON BETWEEN DIFFERENT SCHEMES FOR
GARBAGE COLLECTION
Comparing the schemes for collection and transportation in the project, the traditional
schemes for collection and transportation (The status in Tianjin) and international
recognized schemes, the results can be seen in Table 4-1.
Table 4-1 the comparison between different schemes for waste classification and transportation

etc.), hazardous waste and other types. There is special trash which removed classified and transported by the vehicles from the sanitation in the residential area.
transferred in different periods to the central garbage collection station by air conveyor, and then removed by the vehicles from the sanitation.
Advantages It is easy to operate. And there is hardly technological barriers
The recovery rate of the resources is higher than that of traditional schemes. The cost of investment and operation shall be lower, so it is labor-intensive. It is easy to conduct and operate, furthermore, we can learn from the experience from abroad.
The recovery rate of resource and automation degree of system is higher than the traditional and status. The waste transfer is not affected by the weather. The system can reduce odor, dust and other secondary pollution dramatically. It is featured by high automation and fine labor’s environment.
Disadvantages Environmental pollution is serious. The rate of resource recovery and utilization is low. The garbage in the trash is easy to decay and produce odor, dust and other secondary pollution and visual pollution. It is also easy to breed mosquitoes and rats .All of these are vulnerable to the influences of weather.
It is difficult to operate There are many trashes in the high quantity residential area, the cost on removal and classification is high. The garbage in the trash is easy to decay and produce odor, dust and other secondary pollution. The removal of garbage will increase traffic in residential areas. It is necessary to set up following supplementary system of classification, therefore, it will cost more.
A one-time invest is large, the cost of operation will be higher; The operation and maintenance of the equipment require high technology. The energy consumption is high, and the system operated unstable in the initial operation period. The pipe equipment cleaning will cause the secondary pollution (little impact after being deal); it is necessary to set up the following supplementary system of classification, therefore, it will cost more.

the construction unit and related management departments make the final decision on the basis of taking the above factors into consideration. We will carry out the demonstration if necessary.
Note: the estimation will follow the rule that the compressed car is able to transfer 5 tons of waste.
In the standard scheme, it took 0.04-0.07kg diesel (0.06~0.10 kg standard coal (ce)) to transfer 1t
waste every 1 km. while in the air conveyor feasible report, it will take 1.8 kwh (0.23 kgce) on the
same weight and distance. The actual energy consumption is affected by management and
maintenance, the situation of car and traffic condition. So the data just serves the purpose of
reference.
4.3 THE COMPARISON BETWEEN DIFFERENT SCHEMES FOR
HEAT SOURCES
Comparisons on the scheme of geothermal heat source with that of heat source in this project are
shown in Table 4-2.
Table 4-2 the comparison between different schemes for heat sources
Name of different schemes
Scheme of geothermal heat source Scheme of urban heat source
Content With geothermal heat source for heating through geothermal wells, ground-source heat pumps and other heating facilities to provide required heat.
Directly use the eco-city heating company's heating pipe network to provide required heat. The company plans to use the Beijiang power plant waste heat as heat source (in a small gas-fired boilers for peaking heat source)
Advantages Use renewable energy, non-fossil energy consumption
Directly use the municipal pipe network, the cost is low; Use Beijiang power plant’s waste heat as heat source, which can reduce the thermal pollution and indirectly reduce fossil energy consumption and pollution emissions
Disadvantages
The project has higher volume and the location areas are lack for geothermal resources, therefore only use geothermal heat as heat source can not meet demand, while using other sources of heat to provide co-heating needs a large investment.
The future development of surrounding areas in northern Beijiang power plant will result in increased energy demand, which might affects the northern Beijiang heating power plant in providing heat to eco-city.
28
Conclusion The project planning and scheme that using municipal heat source as heat source is feasible, it is also suggested that eco-city sign a long-term cooperation agreement with the northern Beijiang power plant to ensure the stability of waste heat utilization.

5 PREDICTIONS AND ASSESSMENT OF ENVIRONMENTAL
IMPACT DURING CONSTRUCTION PERIOD
The environmental impact during construction period is mainly caused by dust, noise,
construction waste, construction waste water and domestic sewage, garbage and other
factors caused by workers.
29
5.1 ATMOSPHERIC ENVIRONMENTAL IMPACT
The most important atmospheric environmental impact during construction period is
construction dust, which mainly from the following aspects:
Flattening the land, excavating stacking the earthwork
Transporting and stacking the construction materials (cement, lime, sand, etc.)
Cleaning up and transporting the construction garbage
Vehicles and workers rolled the land
The amount of construction dust and impact are related to the type and character of
building materials, level of mechanization and management, weather conditions and
many other factors, so it is a complex problem and difficult to quantify.
The average wind speed in this area is 3.6 m/s. Estimating the impact distance of
construction dust will be within 200 meters based on experience and analogy. Within
200 meters around the project there are no environmentally sensitive goals. Through
adopting management and technical measures (see Part 5 of this section), 30m outside
of the area can reach the standard, so the construction dust will not cause significant
environmental impacts.
5.2 WATER ENVIRONMENTAL IMPACT
The water environmental impact is during construction period will be minor, mainly
including construction waste water and domestic sewage caused by construction
workers.
Piling, materials maintaining, machinery and vehicle washing and other processes will
produce a small amount of waste water, which contain the particles of soil and
building materials, grease and other contaminants. The composition of construction
waste water is relatively simple. The concentration of pollutants is low. After
depositing by the deposited facility (sedimentation tanks for the concrete pumps and
transport vehicles cleaning should be set up to make secondary precipitation for the
wash water), the water can be reused for watering and greening, therefore the impact
is weak.
The owner of the project arranged the accommodation for the workers (building
apartment). The sewage caused by workers discharges into the sewers and can be
treated by sewage treatment plant. There are also ecological toilets at construction
30
site, or using septic tanks pre–treated, then transferring confined to the municipal
sewage pipe network, so the sewage will not pollute the surrounding environment.
5.3 ACOUSTIC ENVIRONMENTAL IMPACT
Noise during construction period mainly includes the cleaning-up, excavating,
material transferring, stirring, piling, and drilling, grinding and other noise from
machines, equipments and vehicles in the process. The source strength of the noise
depends on the ways of construction, types and numbers of machines and vehicles.
The main source and the source strength of the noise during construction period are
shown in Table 5-1.
Table 5-1 all kinds of noise sources of construction machines at construction site

Air hammer 80~98 Truck(≥10t) 85~94
Concrete crusher 80~90 Excavator 80~93
The noise level of the sound points is calculated as follows:
)(lg20 00
rrRrrLL wp
(Formula 2)
In the formula:
Lp – The sound points (the impact point) accepted by the sound pressure level, dB
(A);
Lw – The sound pressure level of noise source, dB (A);
r – The distance from sound source to the sound points, m;
r0 - The distance from reference position to sound points, m, taking r0 = 1m;
R - Protection structure of the noise source and noise reduction of house, open-air
operation takes R = 0dB (A);
α - The absorption coefficient of the sound wave to the atmosphere dB (A)/m,
0.008dB (A)/m.
According to the formula, we can get the noise level with different distances from
sound source; the results can be seen in Table 5-2.

Note:① The data in the table is based on the open operating condition, without taking the effect
of Shelter materials into account; ② The standard limited value is selected from Emission Standard for Construction Site
Noise at Boundary(GB12523-90).
According to the data in Table 5-2, it can be said that the noise of construction
machinery can be basically compliance in the 200 meters away. Within 200 meters,
the environmental impact is very low because there is no environmentally sensitive
object.
5.4 THE IMPACT OF SOLID WASTE
The solid waste produced in the construction period are construction waste including
construction materials waste , finish materials, sandstone blocks, broken
bricks、concrete, equipment parts waste and so on. In addition, there has domestic
waste is produced by constructors. Construction waste and domestic waste are
generally harmless, but with proper management lacking they will affect the
environment, hinder the traffic and add greatly to fugitive dust pollution. As a result,
the management of solid waste shall be strengthened; reducing spilled and timely
removed from production, transportation, stacking and other phrases, and then
recycled whenever possible. For example, construction waste in the kinds of rubble
and earth-rock can be used as landfill, paving the way for other ways to enhance re-
utilization; resource waste such as waste metal,plastics and papers can be sorted out
and sent to recycling enterprise of materials in regular intervals.
In order to take further measures to control the environmental impact, this project
32
during the construction period must take feasible measures on management and
technology for preventing and alleviating adverse environment effect, in accordance
with the relevant provisions in Tianjin Interim Measures for Management on Fugitive
Dust Pollution Prevention at Construction Site of Construction Project (Construction
[2004] No. 149), Tianjin Management Regulations on Civilized Construction of
Construction Projects(Order of the People’s Government of Tianjin Municipality
No.100) , Guide for Green Projects(Construction [2007] No.223) , Technical
Specification for Green Construction in Sino-Singapore Tianjin Eco-City(Draft for
examination) and so on. A more detailed description is given in Section 7.2.
6 ENVIRONMENTAL IMPACT PREDICTIONS AND
ASSESSMENT ON OPERATION PHASE
6.1 WASTE GAS
In this project,the using of natural gas from residents will generate some waste gas,
which contains dust, SO2、 and NOx. The coverage population of gas for residents
stipulated by the eco-city is 100%. There are 1593 residents, and according to the
quota statistic of heat consumed by residents, the natural gas fired by a person is
0.09m3/h,0.17 m3/h. According to the emission factors of pollutions of Table 4-12 in
The professional qualification registration of EIA Engineer Training Social Region,
burning 100,0000 m3 nature gas can generate 140kg dust, 180kg SO2, 1760kg NOX. It
can be estimated that the pollutant emission of gas by residents consists of dust 0.02
kg/a,0.03 kg/a,0.25 kg/a,such low emission has little impact on the environment.
6.2 AUTOMOBILE EXHAUST
The household vehicles of the project will also discharge few emissions. The main
pollutants of the vehicle emissions are CO, NOx and THC. The concentration of
pollutants of vehicle emissions is interrelated to the driving order greatly. The exhaust
emission is more complex, since in the garage, the low speed of automobiles can be in
many situations, such as enter into and out, turn around and speed out. The project has
designed 114 parking spaces, and all of them are underground. Making an analogy to
the Investigation of air pollutants in the Underground Garage mentioned in
Environmental Impact Statement on the Second Phase of China World Trade Center
Project by Beijing Academy of Environmental Protection Science, the emission of
33
main pollutants in the automobile exhaust of this project is about CO 0.43kg/h, NOx
0.01 kg/h, and THC 0.18kg/h. The automobile exhaust will be discharged outside by
fan. Exhaust pipe will be installed in the middle of green space and road edge, far
away from residential buildings. Since the operation of the project, it will be rare that
the 114 parking spaces are all filled, and the percentage of greenery coverage is 40%,
which will absorb the exhaust to some degree. So it can be predicted that automobile
exhaust will have few impact on the environment.
6.3 DOMESTIC SEWAGE
Wastewater is mainly of domestic sewage from the residents. The total number of
residents in this project is 1593, if the domestic water consumption is on the base of
120L/p·d and there is another public building area of 643m2, the domestic water
consumption is 12 L/(m2d).Drainage modulus is 0.9, the domestic sewage quantity
will be180 m3/d. After the preliminary treatment of the septic tank, the sewage will be
discharged into the municipal pipe network, treated by sewage treatment plant and
then reused and recycled. The removal rate of the CODCr、BOD5 is 20~50%,the SS is
40~60% , the Ammonia Nitrogen is 3~10% after the preliminary treatment of the septic
tank. This assessment to estimate the discharge of the main pollutants is shown in the
table 6-1.

After the preliminary treatment of the septic tank, the water quality of domestic
sewage will measure up to Grade Ⅲ of Integrated Emission Standard of Wastewater
(DB12/356-2008) ; Then the sewage will be discharged into the municipal pipe
network, and reused after the treatment of sewage treatment plant in the eco-city, so it
will not pollute the peripheral environment.
34
6.4 NOISE
The noise in the operation phase of this project will be generated by the residents and
vehicles, pumps, fans and other sound source. Car noise and noise of social activities
make little impact by strengthening management and no tooting.
There is a pump room in the basement. All the water pumps in this project have the
basis on vibration reduction, for example, the pipes are connected with the pump by a
soft joint, and installed by using elastic suspension. It is predicted that in a single
room, equipment synthetic noise is about 80dB (A), the sound insulation of machine
room is 25dB (A), so the noise outside is 55dB (A). Since the pump room is
underground, and the noise can be insulated by the wall outside, it can be predicted
that the noise during operation phase will meet Emission Standard for community
noise(GB 22337- 2008), regional environment will be up to the standard set in
Environmental Quality Standard for noise(GB3096-2008). And in order to reduce
the impact of noise fatherly, it is advised that sound-absorbing materials shall be used
in doors, windows and walls of the fan and pump room, and strengthen the routine
maintenance of equipments.
6.5 SOLID WASTE
The solid waste in this project mainly is domestic waste. The amount of domestic
waste produced by a person one day is 0.8kg, and there are 1593 people, so the total
amount of domestic wastes is 1.3 t/d,470 t/a.
The domestic waste in this project will be sorted collection. The waste metal, glass,
hazardous waste and bulky waste which can’t be entered into the system of collection
and transportation (pneumatic conveying system) will be classified and collected at a
fixed location in the residential area, and the property company will be responsible for
its management. According to the quantities of the waste, the property company will
engage the materials recycling company to recover the waste can be reused, and
engage the unit with disposal qualification of hazardous waste dispose the hazardous
waste; kitchen garbage and other waste will be put into the pneumatic conveying
system after sorted collection, and then transported to the central refuse collection
point for disposal by specialized vehicles.

7 ENVIRONMENTAL MANAGEMENT PLAN (EMP)
According to the requirement of Sino-Singapore Tianjin Eco-City Administrative
Commission, the object of the Green Building Pilot Project is to be a pilot project in
the fields of development and design, construction, operation and management in the
eco-city. According to Word Bank, EMP will be the base for strengthening
environmental management and implementing environmental impact assessment
(EIA). The core of this project will be “Green Building”, which contains as followed:
(1) Be in accordance with the State policy and the features of the eco-city itself.
Green building Pilot Project should first be consistent with national policy and related
standards, but must also take into account the characteristics of region, namely, the
general character of the ecological city and its impact on the district building,
community-specific requirements. The environmental management plan should be
possible to be implemented, copied and popularized. It can provide a reference for the
design, construction and management of the eco-city residential community in the
future.
(2) Be in line with high international standard. Sino-Singapore Tianjin Eco-city
Green building Pilot Project is an international cooperation project between China and
Singapore, is supported by the Global Environment Facility (GEF).Since then, the
project shall learn from international advanced idea on design, construction and
management of “Green Building”, and then integrate and implement these ideas to
each phase by the way of environmental management system, realizing to be line with
high international standard.
So,EMP will achieve the object in the ways as follows:
(1) Expand the concept of green building. "Green building" are not limited to the
project's building or building complex itself, but will be extended to the concept of
"community." In other words, the construction of the region shall also become a
"green" pilot project, and local residents also be included the environmental
management during the operation phase.
(2)Achieve life-cycle management. Formulate the environmental management system
of buildings’ full life cycle, without the limit of loan’s fixed number of years.
(3)Sino-Singapore Tianjin Eco-City Evaluation Criterion for Green Building (the
“Evaluation Criterion”) issued by Sino-Singapore Tianjin Eco-City and order to be
36
issued will become the important norms of the design of eco-city and construction of
green building. This EMP will take these documents as important reference;
determine the responsibility of every shareholder, so as to the establishment of
environmental management system on green buildings in the eco-city.
(4)Reflect the multiple roles that the eco-city administrative departments play in
environmental management of the project. Determine the supervisory functions of
each department that have on owners, design units, EIA units, construction units,
supervision units, property management companies, environmental protection
companies and so on, in the three phases of design, construction and operation;
strengthen the service role of each department that plays on residents and owners
committee; improve the capacity-building of organizing and developing the relevant
training on environmental management.
(5)Take the residents into the community environment management system. Just as
other related parties, determine the responsibility and right of owner's committee in
the community environmental management.
(6)Strengthen the implementation of environmental management measures in the way
of contract management. Add the requirement of environmental management to bid
documents and contracts signed with construction units and supervision units, so as to
ensure that the measures of environmental management will be implemented.
Just as “1.2 Evaluation Level and Scope” said, the whole report is mainly subjected to
public housing pilot project, so is the EMP. Various stakeholders of middle school
pilot project and their environmental management responsibilities, environmental
management measures, environmental monitoring and environmental training in the
main phrases can be referred to the Public Housing Pilot Project. Meanwhile, since
there are some differences in the environmental management measure between the
two projects during operation period, this report provides many environmental
management measures subjected to the Middle School Pilot Project.
7.1 ENVIRONMENTAL MANAGEMENT MECHANISM
Five groups of stakeholders that have responsibilities from designing , bidding to

7.3 ENVIRONMENTAL MONITORING PLAN
Environmental monitoring aims to grasp the pollution trend of the proposed project in time, to understand the environmental impact and the
environmental quality dynamic of operation period in construction on the project area, and obtain timely feedback to the management
authorities, providing a scientific basis for environmental management of the project. Environmental monitoring plan in the project construction
phase is shown in Table 7-5.
For the operating period, taking into account the project sewage is discharged into the sewage and all the eco-city Sewer, to get into the city
sewage treatment plant and recycled water to be processed and recycled, eco-city environmental monitoring station of the regional
environmental air quality monitoring carry out a routine automatic monitoring, its monitoring data can reflect air quality of this project in the
operational phase; this project doesn’t produce strong noise, therefore it is proposed not to implement special environmental monitoring in the
operation phase(For this project to build public water, electricity and property companies will be reporting to the Environment Agency, for
residential water and electricity consumption, mainly in the green building inspection and evaluation of assessment, normal operation process
without rigid control).

8 What environmental protection requirements and recommendations do you have for this project?
We can see by above table:
(1) 54% of respondents know about the program through on-line information,and
understanding via this survey and interpersonal communication accounts for 32%,
14%.
(2) 98% of respondents believe that the project site is appropriate, non-respondents
believe that is inappropriate, and there are 2 percent of respondents with no clear
answers.
(3) 20% of respondents believe that the environmental baseline of project location is
good, 42% of respondents believe that the environmental baseline of project location
is general, 36% of respondents believe that the environmental baseline of project
location is bad, the rest don’t give clear answers. We can see the respondents are not
satisfied with the environmental baseline of project location.
(4) Regarding the environmental impact during construction phase, respondents
consider that dust, noise are the main impact, accounting for 62%, 58%, followed by
solid waste, accounting for 28%, indicating the respondents concentrate in the dust,
noise and solid waste. According to Chapter 5 of this report, the project during
construction phase has complied with <Technical egulations for preventing dust in
cities> and lays down a comprehensive green construction planning and
environmental management plan. And the strict implementation of revelant
70
regulations can effectively control the contamination, and there is no sensitive targets
in the range of 200 meters around the project, so the project during construction phase
will not cause significant effect on the surrounding environment.
(5) Most respondents think living garbage and wasted water are the main problems in
operation phase, accounting for 54% and 44% respectively. This means the main
environmental effect respondents focus are living garbage and wasted water.
According to chapter 6 of this report, this project produces little living garbage in
operation phase and all of them are classified and collected in different categories,
metal and toxic and hazardous wastes are stored in special site, kitchen refues and
other garbages will be transferred to central garbage station and then transported to
garbage processing center or landfill in Hangu district, leaving no negative effect on
the vicinity. Living waste will be processed in chemical pool and then run to water
suppling system of eco-city after it reaches <Standards for discharing wasted
water>(DB12/356-2008). The water will be processed by Ying city sewage farm and
will not contaminate the surroundings.
(6) 96% of respondents think the effect on regional landscape are is good(the rest say
they don’t know)
(7) According to statistics, all respondents hold positive view to this project and none
of them oppose.
(8) Respondents’ requirements and suggestions of environmental protection on this
project are including: take advantage of solar energy, enhance publicity, summarize
experience and make promotions to other districts.
The survey result indicates that those who know the eco-city project really care about
the project and support it. They have fairly good knowledge of environmental
protection and volunteer to participate in environmental assessment. Meanwhile,
respondents put forward some good suggestions as shown in clause (8).
Our staff interview some respondents. Let’s take Miss Ding as an example. She is 29
and holder of master degree, and working as designer in TEDA. The staff get to
know that Ding have been working and living in TEDA for a long time and she know
a lot about eco-city. She says the environmental baseline of the project location is
very bad, just like a desert with no plant or animals. She knows about the location,
design and community development of the project in daily work and think it very
attractive. The project will bring new life to the barren land. She comments that the
71
construction standard of the eco-city is very high and she has read the environmental
management plan of this project, so she think the environmental effect will be
minimal and will not affect the residents’ lives. This is actually very helpful to
environment in the long run. So she fully supports this project.
Mr Han is 25 and a civil servant. He is now living in TEDA but working in the
downtown. He ever went by the project cite and the impression was that it had large
square of land but no life. Mr Han thinks that the dust may be huge regarding its
location and weather. But its positive effect on regional landscape will also be
substantial. At the same time , the green eco-city and buildings are very meaningful
both in and out of China.
9 CONCLUSIONS AND RECOMMENDATIONS
(1)Sino-Singapore Tianjin Eco-city Public Housing Pilot Project is located in Phase
1A site start-Plot No.15 Sino-Singapore Tianjin Eco-city in Tianjin. The project
mainly includes seven residential buildings (With tower high-rise, high-rise
combination plate, 11~18 layers) and neighborhood activity centers and other public
buildings, the total investment is 166.2 million RMB. The Project site is in line with
“the Sino-Singapore Tianjin Eco-city master plan (2008-2020)”. As a non-profit
policy-related house, Public housing is mainly used to address housing problems of
low-income families employed in Sino-Singapore Tianjin Eco-city, with good social
benefits, and also takes a Pilot effect on other plots real estate development in Sino-
Singapore Tianjin Eco-city.
(2)Through the investigation, “the Sino-Singapore Tianjin Eco-city master plan
(2008 ~ 2020) Environmental impact report” atmospheric environment quality and the
regional acoustic environment monitoring data show that SO2, NO2 monitoring daily
average concentration of each monitoring points in Eco-city are in conformity with
category Ⅱ standard of “Ambient Air Quality Standard” (GB12348-2008). Daytime
and nighttime noise levels are in conformity with category Ⅱ standard of “Urban
Regional Noise Standard”, atmospheric environment quality, acoustic environmental
quality status in the project areas are good. Project site plot is land to be built without
surface water and adverse ecological problems.
(3) Main environmental impacts in construction phase of this project are dust and
noise. The impacting distance of construction dust and construction noise will be
within 200 m, and there weren’t environmentally sensitive goals within 200 m during
72
construction phase, therefore, project will not cause significant effect on the
surrounding environment during construction phase.in order to control environmental
during the construction phase, this project must implement “Technical Specifications
for Urban Fugitive Dust Pollution Prevention and Control” ( HJ/T 393-
2007 ) ,“Civilized construction management regulations of Tianjin construction
engineering”(the 100th order of Tianjin government) and correlative regulations.
(4) Main environmental impacts in operation phase of this project are living garbages
and wasted water. After domestic sewage of this project treated initially by septic
tanks during operation phase, water quality is in conformity with category Ⅲ standard
of “Integrated Discharge Standard for Wastewater” (DB12/356-2008); then
discharged into the eco-city governance pipe network and is treated by Yingcheng
sewage plant of Eco-city to recycle and reuse.This does not pollute the surrounding
environment; household garbage generation is about 1.3 t / d during operation phase;
implement separate collection, and deliver to the refuse collection point by the Eco-
city collection and transportation (pneumatic) systems. Kitchen refues and other
garbages will be transferred to central garbage station and then transported to garbage
processing center or landfill in Hangu district, leaving no negative effect on the
vicinity.
(5)Various building design and construction of this project will be in conformity with
“ the Sino-Singapore Tianjin Eco-city Green Building Rating Standards” and “ the
Sino-Singapore Tianjin Eco-city Green Construction Technical Regulation”(will be
formally issued), taking construction fencing, dense mesh and other environmental
protection measures, and unified decoration, installation of solar water heaters, the
implementation of water recycling and economizing on energy, water, land and raw
materials measures, has a good environmental benefits relative to the general real
estate development project.
(6) In order to further control environmental impact of the project, in the entire
process of project planning and design, construction and operation, the Owner,
construction organization, property companies, Environment Bureau, Construction
Bureau and other related parties shall be in accordance with project environmental
management plan, assume the responsibilities and strengthen environmental
protection effectively.
73
Overall, the Sino-Singapore Tianjin Eco-city Green Building Pilot project is in line
with “the Sino-Singapore Tianjin Eco-city master plan (2008-2020)”, has a good
social and environmental benefits relative to the general real estate development
project. By the implementation of the relevant environmental protection measures and
environmental management plans stated by this report, the adverse environmental
impacts of the project during construction and operation phase can be controlled
effectively. On this condition, the project is feasible.
