Since 2005, the Upper Silesian Industrial Park (GPP) has been transforming post-industrial areas on

the border between Katowice and Siemianowice Śląskie into a modern zone of economic and

innovative activity focusing on technological development in compliance with the pro-environment

trend. The organisation undertakes revitalisation projects involving restoration of utilitarian

properties of land deteriorated by industrial activity based on the principles of sustainable

development, such as construction of a complex of energy-efficient office buildings called GPP

BUSINESS PARK.

On the 30th of August 2012 GPP opens the first in Poland energy-efficient building with the

trigeneration system. The state-of-the-art building was named "Goeppert-Mayer” in memory of

Maria Goeppert-Mayer, a Nobel laureate in physics born in Katowice. The other buildings will be

named after three other Silesian Noble laureates and famous scientists: Otto Stern, Kurt Alder,

Konrad Bloch.

The technology used in the building qualify for the highest possible assessment level under the

prestigious sustainable building certification system BREEAM. The building is not only

environmentally friendly but also cost-effective. We expect that energy consumption in our building

will be about 40-50 %less than in typical A class office buildings, without compromising the full

comfort of the tenants. The 7,800 m2 building took 18 months to build. The cost of the project,

including a 3,000 m2 underground parking and landscaping, was about PLN 39 million. Analyses show

that total savings during the use of the building will be about 48%.

Goeppert-Mayer – BREEAM OUTSTANDING project, the second in Europe

Construction of the sustainable building was followed by the decision to apply for a BREEAM

certificate, to demonstrate high level of environmental awareness. The initial, informal assessment

carried out by Buro Happold proved that the project has a chance to achieve high rating in the

BREEAM assessment method. The final result followed our ambition – in September 2013 the

investment got international certificate with the highest available rating – Outstanding. It’s the

second building in Europe with such a high mark.

An outstanding rate proves that the project owner is extremely ambitious and comply with the

highest standards of sustainable construction. In order to qualify as outstanding, a building scored

86,39% of all certification criteria designed to verify whether it is environmentally friendly and

guarantees high comfort of the tenants.

GPP is confident in achieving a high BREEAM certification level thanks to the following solutions

applied in the project:

• TRIGENERATION – process of production of power, chill and heat of gas;

• full integrated building management system (BMS);

• permanent monitoring of thermal comfort and parameters in connection with operating expenses. Monitoring performed in cooperation with Silesian University of Technology, Cracow University of Technology;

• highly-efficient heat recovery system;

• air-conditioning systems based on heating and cooling beams;

• window and façade systems with high thermal insulation;

• advanced system of façades with automatically controlled blinds integrated with the light intensity control system;

• access to daylight guaranteed to all building users;

• air exchange ratio – up to 36 m3/person/hour;

• permanent air quality control;

• energy-efficient lighting system with light intensity sensors – minimum 40% energy savings;

• energy-efficient offices’ humidification system;

• fibre-optic connections to ITC systems;

• quick and energy-efficient lifts;

• rainwater recycling and secondary utilisation system;

• loading stations for vehicles driven with electricity;

• parking places and storage places for alternative transport (bicycles);

• use of certified materials with low content of environmentally-harmful compounds, derived from certified sources, produced with limited CO2 emissions.

The GPP BUSINESS PARK office complex is dedicated, in particular, to companies of the BPO (Business

Process Outsourcing) and SCC (Shared Service Center) sectors.

The application of energy-efficient solutions, modern devices (fully automated and employee-

friendly) increase the comfort of work in the building and enables an actual reduction in operating

expenses, which are so important from the viewpoint of future Lessees. The GPP BUSINESS PARK

complex is situated in the area included in the Katowice Special Economic Zone due to which

Lessees may gain financial benefits comprising tax allowances.

The idea was to create an A class office building that would be perfect in every functional and visual

detail, enable efficient energy management and, last but not least, offer a friendly working

environment for its tenants. According to recently published results of a research conducted by UK

scientists, people work 20% more efficiently in "Green Buildings" than in traditional buildings.

In order to meet the assumptions of a sustainable and energy efficient building, one must use top

quality environmentally-friendly construction materials of high insulation parameters and install

specialist building systems such as for example:

TRIGENERATION – process of production of power, chill and heat of gas. Piston engine powered with

gaseous fuel (natural gas) with high methane content The mechanical energy produced in the engine

is converted by a power generator (combined with the engine using a clutch) into electric energy .

The heat received by the engine cooling system is later used to heat e.g. water and building itself.

During summer the hot water produced powers the second main device included in the trigeneration

system. It is an absorption chiller. The ice water is later channelled to the air-conditioning system

maintaining the relevant comfort in offices.

1. The building will be fitted with an energy-efficient natural and artificial light control system

and with Comfort raster frames with a raster with an increased efficiency due to the Booster

ADV technology

2. The building is equipped with the LITENET energy-efficient natural and artificial light control

system and very efficient light fittings ZUMTOBELL FEC2 B ADV 4x14W M600 LDE for T5 light

bulbs. A heliometric head on top of the building measures the intensity of natural light and

the angle of the sun rays.

3. Air conditioning system enabling optimisation of energy consumption costs.

4. Energy reduction technology in KONE elevators

Trigeneration consists in a simultaneous production of electric, thermal and cooling energy.

The Trigeneration system is based on two main devices.

One of them is the cogeneration module (CHP - Combined Heat and Power). It is a piston engine

powered with gaseous fuel (natural gas) with high methane content.

The mechanical energy produced in the engine is converted by a power generator (combined with

the engine using a clutch) into electric energy with the required parameters (usually with a voltage of

400V and frequency of 50 Hz).

An inseparable feature of each engine is that it heats up during operation. In order to maintain the

appropriate temperature, the cooling system must be applied. The heat received by the engine

cooling system is later used to heat e.g. water.

Another source of heat generated by the cogeneration module includes hot fumes derived from

combustion of gaseous fuel. Depending on the type of the system, the temperature of the fumes

may range from 300 to 500 oC.

The heat received by the engine cooling system and the heat contained in hot fumes may be used to

produce hot water.

During winter season the water is used for the purposes of the central heating (c.o.) and to prepare

hot usable water (c.w.u.).

During summer the hot water produced powers the second main device included in the trigeneration

system. It is an absorption chiller.

Its basic advantage is the very low electric energy consumption, very long life-cycle and a possibility

to use heat derived from the cogeneration module.

The basic task of the absorption chiller is to produce the so-called ice water, i.e. cold water with low

temperature (6-14oC). In the case of the GPP building, the temperature is 14oC. The ice water is later

channelled to the air-conditioning system maintaining the relevant comfort in offices and conference

halls.

The application of the trigeneration system based on the cogeneration module and absorption chiller

does not exclude the use of conventional energy sources. Actually, the opposite is the case. They may

supplement each other and cooperate with each other.

The electric energy is produced “parallel to the network of the Power Plan”. It means that, if at a

given time the system produces more electric energy than the actual demand of the office building,

the energy surplus is resold to the network. If the opposite is the case, the situation is analogical. If

the building’s demand exceeds the maximum electric power of the trigeneration system, the energy

deficiency is received from the network of the Power Plant.

The trigeneration system is the basic source of thermal and cooling energy for the office building. In

peak season, the potential deficiency of the thermal energy may be supplemented by conventional

boiler systems and the deficiency of the cooling energy, by compressor aggregates powered with

electric energy.

The advantages of the trigeneration system used in GPP include:

• a considerable reduction in losses in connection with transports of energy carriers (the electric, thermal and cooling energy is produced at the place of its consumption)

• electric energy saving due to the application of the absorption chiller powered with hot water;

• high efficiency of consumption of the energy contained in fuel accounting for approximately 90%;

• very low pollution emissions due to the use of natural gas as fuel;

• a possibility to change the system operation load;

• fuel availability and transport simplicity;

• financial support in the form of PRCO (Proprietary Rights in Certificates of Origin of the electric energy produced in highly-efficient cogeneration – the so-called “yellow certificates”).

Air conditioning system enabling optimisation of energy consumption costs. A building management

system (BMS) integrated with a weather station, external window blind system, daylight and artificial

light control system, and human presence detection system - automatic minimisation of electricity

and HVAC energy consumption with respect to drying and humidifying.

Swegon GOLD air handling units with an integrated control system and complete range of accessories

for fully automatic operation, provided with complete, required for control and measurement

instruments and automation, integrated in the BMS, centrally positioned temperature and humidity

sensors with monitoring and control functions. This enables analysing CO2 concentration on every

storey of the building, disconnecting fresh air intake and maintaining stand-by temperature in rooms

where no work is done. Central water humidifier guarantees 40% humidity. Air will be distributed

within a single zone by the SWEGON climate system (climate beams with heating and cooling

functions) and fire valves will be applied (as arranged by the tenant) or a common ventilation duct

and rasters in suspended ceilings.

The building is equipped with the LITENET energy-efficient natural

and artificial light control system and very efficient light fittings

ZUMTOBELL FEC2 B ADV 4x14W M600 LDE for T5 light bulbs. A

heliometric head on top of the building measures the intensity of

natural light and the angle of the sun rays. The system

automatically increases or reduces the intensity of artificial light in

the building depending on the external conditions. The system also

controls window blinds to eliminate unpleasant dazzling effect

when the sun is shining straight on the building walls. The control

system is also equipped with human presence sensors that

automatically switch off the light in empty rooms. The LITENET

system guarantees an illuminance of 500 lx at workstations. The

above solutions enable 40% to 70% savings on lighting energy consumption. The building is also

provided with an emergency lighting system. Distribution of lighting fittings: ≈ 1 fitting/ 6m2.

Three KONE elevators were installed in the building to enable communication between the respective storeys. One of the elevators is adapted to the needs of disabled persons and is additionally communicated with the underground parking. The nominal speed of the elevator is 1.6m/s. Energy reduction technology in KONE elevators

1. Energy-efficient drive

EcoDisc®, compact gearless drive with

a slow-speed synchronous motor

and variable frequency control consumes

twice less energy than traditional drives. It is

equipped with a vector inverter and economic

energy recovery system. No working oil

needed. 2. Energy recovery system

A highly efficient energy recovery system

converts the energy generated while

braking

an elevator into electricity and redirects it

to the network. As a result, an 8-person

MonoSpace® elevator saves 20% of the

energy needed to operate it.

3. Energy efficient lighting in an elevator car

KONE elevators are equipped with energy-

efficient

light bulbs and LED lamps, which are

10 time more durable than halogen lamps

and use

80% less energy.

4. Stand-by options

Lighting, display lamps and ventilation working in an elevator that is not being used for even a short time are a source of major yet completely unnecessary costs. Stand-by options switch off any temporarily unnecessary functions in an elevator: • automatic switching off of lighting or ventilation in an elevator car • automatic switching to a lower power consumption mode • automatic dimming of display lamps in an elevator car

How does the REGEN regenerative drive work?

• The regenerative drive technology is used to convert braking energy into electricity. The elevator drive acts as a generator.

• When an empty elevator car goes up or when it goes down fully loaded, the counterweight or the car become the drive, and the KONE EcoDisc - the generator. Energy may be recovered for example when a loaded elevator car goes down to the ground floor.

• The regenerative drive recovers the energy generated by the elevator and converts it into electricity, which may be used for instance to light the building.

• As a result, the total energy consumption in the building is reduced.

• Up to 30% of electricity used by an elevator may be recovered.

Selt C 80 window blinds - façade mounted blinds with a complete set of accessories - centrally

controlled and automated from the weather station, integrated with the BMS and lighting control

system. It is also possible to control each group of blinds from the same room with CIRIA adjusters.

The window blind system is mounted on three façades: East, West and South.

Maria Goeppert Mayer was born on June 28, 1906, in Kattowitz,

Upper Silesia, then Germany, the only child of Friedrich Goeppert and

his wife Maria, nee Wolff. On her father's side, she is the seventh

straight generation of university professors.

In 1910 her father went as Professor of Pediatrics to Göttingen where

she spent most of her life until marriage. She went to private and

public schools in Göttingen and had the great fortune to have very

good teachers. It somehow was never discussed, but taken for granted

by her parents as well as by herself that she would go to the

University. Yet, at that time it was not trivially easy for a woman to do

so. In Göttingen there was only a privately endowed school which

prepared girls for the "abitur", the entrance examination for the university. This school closed its

doors during the inflation, but the teachers continued to give instructions to the pupils. Maria

Goeppert finally took the abitur examination in Hannover, in 1924, being examined by teachers she

had never seen in her life. In the spring of 1924 she enrolled at the University at Göttingen, with the

intention of becoming a mathematician. But soon she found herself more attracted to physics. This

was the time when quantum mechanics was young and exciting. Except for one term which she spent

in Cambridge, England, where her greatest profit was to learn English, her entire university career

took place in Göttingen. She is deeply indebted toMax Born, for his kind guidance of her scientific

education. She took her doctorate in 1930 in theoretical physics. There were three Nobel Prize

winners on the doctoral committee, Born,Franck and Windaus. Shortly before she had met Joseph

Edward Mayer, an American Rockefeller fellow working with James Franck. In 1930 she went with

him to the Johns Hopkins University in Baltimore. This was the time of the depression, and no

university would think of employing the wife of a professor. But she kept working, just for the fun of

doing physics. Karl F. Herzfeld took an interest in her work, and under his influence and that of her

husband, she slowly developed into a chemical physicist. She wrote various papers with Herzfeld and

with her husband, and she started to work on the color of organic molecules. In 1939 they went to

Columbia. Dr. Goeppert Mayer taught one year at Sarah Lawrence College, but she worked mainly at

the S. A. M. Laboratory, on the separation of isotopes of uranium, with Harold Urey as director. Urey

usually assigned her not to the main line of research of the laboratory, but to side issues, for

instance, to the investigation of the possibility of separating isotopes by photochemical reactions.

This was nice, clean physics although it did not help in the separation of isotopes. In 1946 they went

to Chicago. This was the first place where she was not considered a nuisance, but greeted with open

arms. She was suddenly a Professor in the Physics Department and in the Institute for Nuclear

Studies. She was also employed by the Argonne National Laboratory with very little knowledge of

Nuclear Physics! It took her some time to find her way in this, for her, new field. But in the

atmosphere of Chicago, it was rather easy to learn nuclear physics. She owes a great deal to very

many discussions with Edward Teller, and in particular with Enrico Fermi, who was always patient

and helpful. In 1948 she started to work on the magic numbers, but it took her another year to find

their explanation, and several years to work out most of the consequences. The fact that

Haxel,Jensen and Suess, whom she had never met, gave the same explanation at the same time

helped to convince her that it was right. She met Jensen in 1950. A few years later the competitors

from both sides of the Atlantic decided to write a book together. In 1960 they came to La Jolla where

Maria Goeppert Mayer is a professor of physics. She is a member of the National Academy of

Sciences and a corresponding member of the Akademie der Wissenschaften in Heidelberg. She has

received honorary degrees of Doctor of Science from Russel Sage College, Mount Holyoke College

and Smith College. They have two children, both born in Baltimore, Maria Ann Wentzel, now in Ann

Arbor, and a son, Peter Conrad, a graduate student of economics in Berkeley
