Performance Evaluation of Conventional and Non-Conventional Wall Compositions in Cold Climatic Zone of India

Abstract: India is developing at a rapid pace. Energy requirement has increased many folds in recent decades and will continue in same direction. A major share of energy is used in domestic sector to maintain comfortable indoor climate for the occupants. Energy demand in a building can significantly be reduced by 1/3rd by proper planning and material use considering local climate. This paper aims to understand the fenestration design in cold climatic zone of India considering Dehradun as case study area. The main objective of this study is to understand the impact of fenestration composition on heat loss through building envelope. This paper discuses Five fenestration options in the building design against the conventional system of 220 mm thick brick wall. It has been observed that the conventional wall system discussed above doesn’t perform optimally compared to others. This paper further discusses the use of other fenestration composition which can be utilized to save heating demand to reduce energy consumption in long run.
