1.4.3 TERI, Bangalore
TERI has provided a unique environmental solution with its model energy-effi cient building at
Domlur, Bangalore, and aff ording maximum comfort through minimum use of conventional
electricity. Bangalore being in a moderate climate zone of India has comfortable temperature round
the year.
The building boasts of an innovative design to make maximum use of the natural resources. It
opens towards the northern side facilitating access to glare-free light.
A solar wall towards the south side of the building directs the fl ow of the breeze over the
building. This, in turn, creates a negative pressure and pulls fresh air from the north into the
building. Air conditioning is fully avoided and the building maintains comfortable conditions round
the year.
Optimum use of appropriate building envelope, use of energy-effi cient lamps, luminaries, control
strategies have been employed to reduce dependence on artifi cial means of lighting and to create
comfortable conditions.
By creating atrium spaces with skylights, sections of the Centre are designed in such a way that
natural daylight enters into the heart of the building, considerably reducing the dependence on
artifi cial lighting. This is supplemented by a skylight roof and energy-effi cient artifi cial lighting. A
roof garden has also been developed to reduce heat gain.
Solar water heating meets the hot water requirements of the kitchen and other utilities. A 2-kW
peak solar photovoltaic system meets a part of the power requirement. Rainwater harvesting is used
to manage water in the complex. The collected water is treated and used for various maintenance
purposes, like use in sprinklers for landscape covers. The sections are worked out so as to allow hot
air to rise towards the top. Natural ventilation occurs with the air fl owing from the ground fl oor to
the terrace because of the open nature of the volumes. The building does not need air conditioning
round the year and has minimum lighting requirement during daytime. The annual average energy
consumption is only about 30 kWh/sq m.
1.4.4 TERI, Mukteshwar
TERI’s Himalayan centre is located in Latey Bunga, Mukteshwar, 2300 metres above sea level.
The facility has a residential wing, is addition to conference hall, meeting area, and rest rooms.
The general orientation of the building is south-east, ensuring that all major openings are in line
with the sun. In accordance with strategic landscaping principles, trees have been planted on the
northern side of the building to provide a buff er against cold winds. The building is thus optimally
day lit and receives solar radiation for heating. Furthermore, each suite comes attached with unique
solar passive features known as ‘sun-spaces’. These enhance heat gain by day and emit it by night,
when it is required. Judiciously planned corridors in front of the habitable spaces dilute the glare of
the sunlight, while trapping solar radiation.
Renewable energy systems in the form of photovoltaic solar panels have been integrated into
the roof of the utility building and conference hall to meet a portion of the electrical requirements.
An eff ective solar water heating system is in place to meet the hot water requirements of the
building’s inhabitants. In the absence of suffi cient sunlight, battery banks provide a power back-
up for three days. Fibreglass panels in the ceilings and walls act as insulation, preserving heat and
improving acoustics.
