ENVIRONMENTAL FRIENDLY FEATURES<br />
USED IN THE BUILDING<br />
The building uses environmental friendly features like<br />
cavity wall with insulation, insulated roofs and rainwater<br />
harvesting. The thermal comfort inside the building was<br />
achieved by using features like external cavity wall with<br />
insulation and double glazed exterior windows. Two layers<br />
of 120mm brick wall with 80mm cavity gap forms the<br />
exterior skin of the building. The cavity gap incorporates<br />
50mm thick ‘Extruded Polystyrene Thermal Insulated<br />
Board’ (Styrofoam Board) for additional thermal comfort.<br />
To increase the efficiency of insulated cavity walls, the<br />
openings on walls which include the exterior doors and<br />
windows have double glazed glass panels. These features<br />
were introduced to keep the building warm during winters<br />
and cool during summers without having to use any<br />
energy source for it. Likewise the ceilings in the rooms that<br />
have open terrace above are also insulated.<br />
The building also uses the rain water harvesting. The<br />
rainwater is collected in two HDPE tanks of 5000 Litre<br />
