14. REDUCING ENERGY CONSUMPTION (COMPARED TO GRIHA BENCHMARKS) WHILE MAINTAINING OCCUPANT COMFORT. • For achieving visual comfort: All fenestration designed to provide glare free usable daylight in most areas. As this is a daytime use building, it has been designed to run only on daylight. Most of the spaces run on daylight throughout the year. (Spaces designed to achieve daylight levels of about 150lux). Projectors in the classroom have been selected to work with the available daylight so that blinds could be avoided. • For achieving thermal comfort: All rooms have buffer spaces outside in form of corridors or jalis in order to reduce solar gains into the rooms and maximise comfort. Optimized shading based on orientation in order to provide complete shading in all spaces throughout the year while maximizing daylight. GRC jalis used on the East and West facades to maximize shading. High performance selective used to reduce solar gains further. Different types of glazing used in different sections based on shading and orientation to ensure a balance between daylight and solar gains. Number of openable windows calculated based on use and orientation of each space. Low level and high level openable windows provided on both sides of the rooms to both cross ventilation and stack ventilation. Double wall with insulation in the cavity provides both thermal mass and insulation to maximize thermal lag.
