RETREAT: Resource Efficient TERI Retreat for Environmental Awareness and Training, Gurugram
RETREAT is a powerful combination of modern science and traditional knowledge. Situated in Gual Pahari, Gurugram it is 36 hectare of TERI campus with lush green landscape.
Architect:- Sanjay Prakash and TERI
Built up area:- 3000 sq.m.
Campus include facilities such as 30 room training hostel boasts of conference facilities for 100 people, Dining and Kitchen, Recreational area, Computer room, and a Library.
TERI being a Energy and Resource Institute believes and specialize in field of energy, environment and sustainable development. This Building would not put any pressure on Earth’s ecosystem. It demonstrates efficient utilization of energy, sustainable, and integrated use of both natural resources and clean and renewable energy technologies, and efficient waste management.
Design Features
- Orientation, Insulation, and Design of building- Building oriented along the east- west axis to have maximum exposure along north and south as per the composite climatic condition of Gurugram, the north block is made slightly concave towards the front, while the south block forms a hybrid convex surface facing the winter sun. South side partially sunk into the ground to reduce heat gain. East and West walls have shaded openings. Walls are insulated with 40 mm thick polystyrene, Roof insulated with Vermiculite concrete topped with china mosaic.
2. Underground Earth air tunnel- Earth air tunnel or earth air heat exchanger is a pre-cooling or pre-heating system which consists of a pipe or network of pipes buried at reasonable depth below the ground surface. It either cools the air by rejecting heat to the ground or heats the air absorbing heat from the ground. It utilizes the fact that the deep earth temperature remains almost same as the annual average mean air temperature of the location. In RETREAT, 4 tunnels of 70 m length and 70 cm diameter each laid at the depth of 4m below the ground to supply conditioned air to the rooms, Each room in south block has solar chimney in which warm air rises and escapes and the cooler air from the underground tunnels rushes into to replace warm air.
3. PV ( Photovoltaic Panels)- Photovoltaic cells use sunlight as a source of energy and generate direct current electricity. A collection of PV modules is called a PV Panel, and a system of Panels is an Array. Arrays of a photovoltaic system supply solar electricity to electrical equipment. Sun is the powerng force of RETREAT, where solar panels are used to form a solar roof. RETREAT has also installed PV gasifier hybrid power plant. The power available from gasifier and roof integrated PV system is sufficient for the building, excess power is used to charge batteries.
4. Daylighting – Very efficient use of daylight with skylights placed correctly to avoid glare and heat. For lighting, RETREAT also used time based control switch off lights to preset time. Key tag system is installed in the room for energy conservation.
5. Waste management- Wastewater is recycled using the root zone technique. It is a natural wastewater treatment process based on aerobic and anaerobic decomposition of the contents in the roots of the reeds and microbial organisms. This water is used for irrigation.
RETREAT is perfect example for green building in 21st century.
