Indo-Swiss Building Energy Efficiency Project

From winter to spring to summer now! The pendulum of weather swung from one extreme to the other in the past few months in several parts of the country. Having achieved a few milestones

and initiated new activities, the Building Energy Efficiency Project (BEEP) has much to report on from its various activities carried out in the past few months.

Milestones first. The first BEEP charrette project, Aranya Bhavan, became operational on 21 March 2015. Aranya Bhavan is the office building of the Rajasthan State Forest Department. The building was inaugurated in Jaipur by Ms Vasundara Raje, Hon’ble Chief Minister of Rajasthan. It is also ECBC compliant. The charrette conducted for this building had suggested a slew of measures leading to about 30% energy savings.We shall keep monitoring the performance of the building in the months to come and shall report on the same for the benefit of all.

Another milestone is the release of the Design Guidelines for Residential Buildings in Compos-ite and Hot-Dry Climates.The publication lists out 15 recommendations, which, if implement-ed, can bring about substantial energy savings without compromising on the comfort factor. The publication was released on 2 September 2014 by Mr Dharmendra Pradhan, Hon’ble Minister for State for Petroleum and Natural Gas, Government of India. You can download the Design Guidelines free of charge from the BEEP website. It has been widely distributed in different States and Municipalities.‘Lead Article’ in this issue covers some background study conducted for the project. Also, be ready to receive another publication that will focus on warm-humid climate!

Several integrated design charrettes were organised during the past few months across the country. The details of these have been given in the ‘News’ section of this newsletter. Amongst all BEEP activities in the past six months, the charrette conductors training pro-gramme deserve special mention here. This capacity building initiative targeted practis-ing building design professional teams with minimum 8 years of experience. Each team included an architect, an HVAC/energy engineer, and a project manager. This was a novel experience for both the participants as well as the trainers. Mr Andreas Binkert, one of the trainers, shares his experience in an interview to this newsletter. We hope to continue this programme in the future.

Another encouraging development for BEEP has been the signing of memoranda of under-standing (MoUs) with five Indian labs. With these MoUs, BEEP and the partner labs will jointly organise capacity building programmes over the next one year across the country.

A national design competition on external movable shadings has been launched and is now in its second phase.

Overall, the past few months were ‘eventful’ and productive from BEEP’s perspective. Our satisfaction emerges from the fact that BEEP’s activities are increasing among the core stake-holders across the country.

Stay tuned for the next update and, in the meantime, write in to share your experiences.

Thank you!

2 Indo-Swiss Building Energy Efficiency Project

Introduction

India is experiencing unprecedented urbanisation due to the transformation of cities into economic hubs. According to 2011 census data, about 31%

of India’s population was residing in urban centres, and this percentage is expected to increase to 40% by 2030. It is estimated that the total constructed built-up area would increase from 8 billion square metres (m2) in 2005 to 41 billion m2 in 2030 (about five-fold increase) (Mckinsey & Company 2009). This situation is significantly different from the developed coun-tries, where the buildings are already constructed to a large extent. The scenario in India, therefore, provides both challenges and opportunities to stakeholders in the building sector to develop this building stock ap-propriately.

As per the 2005 report of the Central Electricity Authority (CEA 2005), the residential sector consumes 21% of the total electricity generated in India, which is about three times more than that of the commercial building sector. One of the reasons for this is that the built-up area of residential buildings is about seven times more than that of commercial buildings (Mck-insey & Company 2009). The energy-use intensity of residential buildings is expected to grow because of the anticipated increase in air-conditioned area, bet-ter access to electricity, and increase in ownership and usage of appliances.

Context and Methodology for Developing the GuidelinesThe work presented in this article was carried out un-der the Indo-Swiss Building Energy Efficiency Project (BEEP) as a background research leading to the de-velopment of energy efficiency guidelines for the de-sign of new multi-storey residential buildings in the composite and warm-humid climatic regions of India.

The guidelines for residential building design recom-mend (a) reduction of operational energy and (b) im-provement of thermal comfort of the residents. This article presents only the monitoring and analysis of the monthly energy consumption of residential units in Delhi-NCR and Chennai.

Data were collected for a duration of one year from 732 residential units (from four residential com-plexes) in Delhi–NCR and 417 residential units (from six residential complexes) in Chennai. The residential complexes selected for this study were 3 to 15 storey high apartment buildings. The units selected were a mix of two and three BHK (bedrooms, hall, kitchen) apartments with a area1 ranging between 80 m2 and 130 m2. The residents of these houses primarily repre-sented the middle and middle upper income group of India. As these results are based on a small sample size, they should not be taken as baseline data on EPI (Energy Performance Index) or electricity consump-tion for multi-storey residential buildings in India. However, the results do help in developing a better understanding of current electricity usage, particu-larly for space condi-tioning.

Data for monthly energy consumption were collected to un-derstand the baseline scenario of energy consumption in the composite climate (represented by Delhi-NCR) and warm-humid (represented by Chen-nai). These climatic zones constitute al-most two-thirds of the total geographical area of India (Figure 1).

The collected data was then filtered and the us-able data left after this filteration process were 89% and 86% in composite (Delhi-NCR) and warm-humid (Chennai) climates, respectively. The parameters un-der which this filtered data was statistically analysed were the EPI distribution, monthly energy consump-tion profiles, and share of electricity for space comfort conditioning. In order to understand the trend of en-ergy consumption over a period of time, time series data (for 8 years) were collected from one of the resi-dential complexes in Delhi.

Subsequent to the collection of monthly electric-ity data, a monitoring campaign was carried out in four selected residential units (two each in Delhi and Chennai) to understand the needs and usage pattern of the space comfort conditioning equipment (fans, desert coolers, and air-conditioners). This monitor-ing included discrete logging of space and ambient hygrothermal conditions and energy consumption of space comfort conditioning equipment.

The information gathered from the monitoring ex-ercise was used to define inputs and validate outputs of the baseline energy simulation models for both the climatic zones. The potential of individual and clustered strategies will be evaluated by conduct-

ing parametric runs on baseline simulation models. The inferences drawn from these simulation analyses were used to formulate climate-specific design guide-lines. In 2014, a publication titled, Design Guidelines for Energy-Efficient Multi-Storey Residential Buildings for Composite and Hot-Dry Climates, was released <http://beepindia.org/resource/Residential-guide-lines>. The design guidelines for the warm-humid cli-mate will be released during second half of year 2015.

Analysis ResultsResults of analysis of monthly electricity consumption data for sample flats in composite and warm-humid climatesThe mean EPIs for residential flats in composite (732 residential units) and warm-humid climate (417 resi-dential units) were calculated as 48 kWh/m2.year and 44 kWh/m2.year, respectively (Figures 2 and 3).

complex in composite climate shows steep increase in energy consumption during the summer and mon-soon months (May–August). This can be attributed to the operation of air-conditioners for attaining ther-mal comfort in spaces. February and March can be considered as base months, when the need for com-fort cooling and comfort heating is minimal.

Average monthly electricity consumption for the residential complexes in warm-humid climate (Figure 4) shows a flatter profile, with peak appearing during the May to July months. December and January can be considered as base months when the requirement for space comfort cooling is minimal. The reduced amplitude of average monthly electricity consump-tion during the summer months in warm-humid cli-mate compared to that of composite climate may be attributed to the increased use of late evening sea breeze for natural ventilation and use of ceiling fans for space conditioning.

The EPI range distribution for both composite and warm-humid climate showed that 16% of the resi-dential units in both the composite climate and the

warm-humid climate have a high EPI of over 70 kWh/m2.year (Figures 5 and 6). Most of these residential units have three or more air-conditioners and hence can be considered to represent the case when most of the frequently used spaces inside an apartment have provision of air-conditioning. There are 52% households (Figure 6), which have EPIs less than 40 kWh/m2.year (below average); this may be attributed to predominant use of natural ventilation and ceiling fans for meeting thermal comfort for a large part of the year.

Time-series data on electricity consumption from 2006 to 2013 for a 90 residential unit in a multistory complex were analysed. The average electricity con-sumption data for the occupied residential units in a typical summer month (May) were plotted for 2006 to 2013 (Figure 7). The plot provides an important in-sight into the impact of electricity consumption due to the increased use of room air-conditioners. In 2006, the residential units were predominantly using des-ert coolers and fans for space conditioning. Gradually, a majority of desert coolers were replaced by room

air-conditioners. By 2010, room air-conditioners had become the dominant mode of space cooling. It can be observed that the electricity consumption (kWh/occupied residential unit) more than doubled, from around 300 kWh per occupied residential unit in 2006 (with predominantly desert coolers) to 700–800 kWh per occupied residential unit (with predominantly room air-conditioners).

Results of detailed energy consumption monitoring in three flats in the composite climate

An analysis of energy consumption in three flats in the composite climate is given below (Figure 8). a) Flat A having a below average EPI (in the range of

30–40 kWh/m2.year) b) Flat B having an above average EPI (in the range of

60–70 kWh/m2.year) c) Flat C having high EPI (>70 kWh/m2.year).

Flat A used convective ceiling fans from mid-March to mid-October, two evaporative desert cool-ers from April to June, and two air-conditioners from

June to July. The EPI of this flat was 35 kWh/m2.year. Monitored data show that almost 33% of the annual energy consumption is attributed to operation of comfort space-conditioning equipment. The remain-ing 67% of the electricity (referred in this article as base energy consumption, i.e., energy used for pur-poses other than comfort cooling) is used for refrig-erator, lighting, washing machine, electric geysers, kitchen appliances, TV, computers, etc.

Flat B used two air-conditioners predominantly for comfort cooling and had an EPI of 65 kWh/m2.year (~1.8 times compared to Flat A).

Flat C with 4 air conditioners had an EPI of 117 kWh/m2.year (~3.3 times compared to Flat A). If en-ergy consumption during February is considered as base energy consumption2 for Flat B and Flat C, then the contribution of energy consumption for comfort space conditioning can be as high as 38% for Flat B and 65% for Flat C.

ConclusionsThe main findings of the analyses are listed below.

1. The mean EPIs for sample residential flats of 2–3 bedrooms in composite (732 flats) and warm-humid climate (417 flats) for the year 2009 are calculated as 48 kWh/m2/annum and 44 kWh/m2/annum, respectively.

2. Energy consumption for comfort cooling is a sig-nificant part of the electricity consumption. De-tailed analysis of energy consumption in three sample flats shows that the contribution of en-ergy consumption for comfort space conditioning increases with the increase in EPI (and increased usage of air-conditioners); the contribution for the three flats was estimated to vary between 33% to 65% of the total energy consumption.

3. Analysis of time-series data for one residential complex for 2006 and 2013 shows that in the summer the electric-ity consumption (kWh/occupied resi-dential unit) more than doubled, from around 300 kWh per occupied residen-tial unit in 2006 (with predominantly desert coolers) to 700–800 kWh per oc-cupied residential unit (with predomi-nantly room air-conditioners).4. Detailed energy consumption mon-itoring of a flat, which uses a combina-tion of fans, evaporative coolers, and

air-conditiioners for cooling, shows potential of large energy savings by appropriate energy-effi-cient use of comfort cooling appliances.

6 Indo-Swiss Building Energy Efficiency Project

You’ve been part of charrettes in India and elsewhere. What has been your experience of these charrettes? Are there different challenges in India and elsewhere?

Charrettes always come with a big adrenalin boost. The clients have high expectations and all participants are under pressure for success. The challenge is to find the trigger points in the project where a substantial improvement (i.e., energy savings) can be achieved with minimal effort. That is true in India as elsewhere. But in India, the clients tend to expect energy savings with very short pay-back periods rather than calculating life-cycle costs.

What role does the architect play in these charrettes? Any special skills required?

The architect is the generalist. He does not have the specialized skills of a mechanical engineer or a green energy specialist. But he can bring these special skills to fruition by combining the knowledge of active and passive measures to multiply their effect for the client. And he must be a good communicator who can translate specialists’ lingo into the client’s language to be understood – and hopefully accepted and implemented.

What are the architectural design issues that are important to make a building energy efficient?

All architecture is local. Macro factors such as climate, latitude, local building methods, and culture must be taken into consideration. The micro factors such as orientation of the structure, building mass versus envelope, insulation versus cross ventilation, openings and shading devices are also key to energy efficiency.

For commercial buildings often the mechanical systems are emphasised for energy efficiency, which leads to the misconception that glass boxes are okay. Why is the architectural design equally important and how can we promote this?

Efficient mechanical systems are very important when attempting to reduce the energy consumption of a building. They can correct the ‘design mistakes’ to a certain degree, which will help conserve energy. However, these systems still require energy to function in the daily life of a building! Much more efficient therefore would be a smart architectural design that avoids entirely or at least greatly reduces the need for such mechanical systems. We must promote energy-efficient design and weigh its potential extra costs

Andreas studied at Federal Institute of Technology of Zurich in 1979. He has over 30 years of architectural and teaching experience in Switzerland, USA and Canada. He is a partner and Senior Vice President at Nüesch Development and manager of its Zurich and Lucerne offices. His recent work include the planning and development of EbiSquare, the lifestyle mall to be built in Lucerne, Switzerland.

He is one of the Swiss experts conducting BEEP integrated design charrettes.

against the reduced installation costs of mechanical equipment and the minimised energy consumption during the life cycle of the building.

From your experience as an architect as well as a developer, how is the integrated design process advantageous?

When a client signs up for an integrated design process, he already has made the most important step: He has enabled all specialists involved in the development of his building to talk to each other, learn about each other’s needs, hopes, and limitations and to start acting as a team rather than as uncoordinated separate entities. The advantages of integrated design process lay not only in a better product but also in an accelerated learning curve of all parties involved.

What are your suggestions to improve the charrette process?

In the past, we used to be satisfied if we were able to show the client a variety of methods for energy reduction. Now we begin to include approximated cost implications as well. By doing so, the client is not only made aware of the life-cycle costs of the proposed energy reduction measures but will be eased into a position where he can choose from different alternatives. He will also start to understand the importance of offering a high comfort level within the building. Higher comfort for the tenants will result in more efficiency and a greater output. I suggest looking at the broader spectrum of factors impacting energy efficiency – for the benefit of the client and the inhabitants of the building.
