The actual energy performance index of the Master’s residence building is 30.15 kWh/m2/yr, based on the measured energy consumption of the building. Various measures are taken to improve the overall performance of the building, which are
|Year of completion||2009|
|Number of units||None|
|Number of occupants||None people|
Masters residence, Doon school consists of two residential units. Both the units are properly oriented to avoid the excess heat gain in the building. To reduce the solar gains through windows, external shading elements in the form of overhangs, and high performance double glazed windows have been provided in the building.
The building envelope comprises of heavy weight construction. The external wall of building has U factor of 0.220 W/m2K. The external wall consists of 12 cm brick cladding, 23 cm brick wall, 8 cm extruded polystyrene, and 12 cm brick work. The upper ceiling envelope consists of 10 cm brick, 13 cm RCC slab and has a U value of 2.340 W/m2k
Windows are double-glazed units with gas filling (SHGC 0.25) and an aluminium frame. Total window area inclusive of the frame is 105.9 m2.

There is no heating system installed in the building.
The packaged air conditioning system comprising of cassette and split AC’s has been installed in the building. The ACs installed in the building are BEE 4 or 5 star rated.
No hot water system has been installed in the building.
The building spaces are designed for natural ventilation with ceiling fans and manual operation of windows.
Energy efficient lighting has been used such as LED for outdoors and tubular fluorescent lights for interiors have been installed. Interior lighting power density of the project is 2.29 W/m2. All air conditioners installed in the building are BEE 4 or 5 star rated.
The energy consumption from the building is from grid connected power. Due to thick envelope construction with selecting proper U value the thermal load of the building has reduced considerably. All appliances installed in the buildings are energy efficient lighting systems and energy efficient air conditioners and hence the operating demand of the building has also reduced considerably. Building consumes approximately 5,728 kWh of electricity from grid annually.
|Primary energy consumption||5728.00 kWh/year|
|Primary energy consumption (ref. building)||16518.00 kWh/year|
|Specific primary energy consumption||30.15 kWh/m2/year|
|Specific primary energy consumption (ref. building)||86.94 kWh/m2/year|
