Due to low-income workers' strong need for low-cost housing and India's mixed environment, new-built housing stock must be cost-, durability-, and efficiency-conscious. Walls make for a large amount of building costs, thus choosing a wall system is crucial. This option depends on how durable, pleasant, eco-friendly, and affordable a system is to fulfil quality and cost criteria. Energy efficient building offers for robust, economical, and sustainable housing, but it's not well-known. So, the building sector has ignored its sustainable qualities. This article compares the thermal characteristics and overall Life Cycle Costs (LCC) of building walls with local developed insulated walls in one of Rajasthan's hottest locations. In-situ temperature and heat flux measurements were taken following ISO 9869 to determine yearly energy needs. Total LCC was based on initial construction costs and yearly energy expenditures for building wall systems. sustainable housing has a lower U-value than brick walls, resulting in reduced yearly energy consumption and a 70% annual energy cost savings. This savings, along with low initial building costs, rendered the optimal sustainable walls cheaper over 30 years than the burnt brick unit.
