Description
Summary:Abstract The hot and dry climate of Jodhpur city in India, presents difficult conditions to maintain thermal comfort in a residential building. The proliferated consumption of electrical energy to fulfill these demands has made it more difficult to achieve sustainability. This research article explores a unified method to evaluate RETV compliance in arid climate and particularly emphasizing on the distinctive architecture and climatic conditions. It develops an emergent connection of directional sandstone walls with residential energy efficiency, contributing fresh insights to the unaddressed aspects of sustainable architecture in arid regions. To solve this, the study involves the role of vernacular sandstone wall and deeper overhangs, orientation of the building, thickness of wall, and glazing used in attaining energy efficiency using the Residential Envelope Transmittance Value RETV adhering to Eco Niwas Samhita guidelines. The method inculcated a process of comparing two sets of residences, which are southwest and northeast-oriented, with wall thicknesses of 600 mm and 300 mm, besides different window glazing and Solar heat gain coefficient SHGC. The findings show that wall thickness and deep projections, glazing and orientation factor considerably affects RETV, with values ranging from 15.49 W/m² to 8.43 W/m². This paper gives the practical recommendations to design energy efficient homes in arid climate, contributing towards sustainability in residential architecture.
