Energy matrices of the building by incorporating daylight concept for composite climate—An experimental study

In this paper, an attempt has been made to implement the concept of daylighting to conserve conventional fuel in a building known as SODHA BERS COMPLEX (SBC) at Varanasi, UP, India. The performance has been analyzed in the context of energy conservation. The building SBC is designed to provide sufficient daylighting, ventilation, as well as thermal comfort to occupants with optimum use of available space for a residential area. The two uppermost rooms of the building have been studied under clear sky conditions. It has been observed that (i) over the lifetime of the building an average energy saving from daylighting is found to be 7933 kW h, which corresponds to 16.18 tons of CO2 mitigation, and (ii) an energy payback time, energy production factor , and life cycle conversion efficiency of SBC are observed to be 5.5 yr, 9.09, and 0.17, respectively.
