Performance evaluation for energy efficiency attainment in buildings based on orientation, temperature, and humidity parameters

ABSTRACT Energy consumption in buildings and infrastructure has increased many folds suggesting a need to shift towards energy efficiency and conservation as well as operation of buildings through sustainable means. In buildings, energy efficiency can be achieved using insulation materials, improved architectural techniques, and modified construction methodology. However, energy demand to operate buildings must be reduced without compromising their performance and services. To study energy consumption effectiveness, observational and experimental investigations were carried out on four existing buildings and a model based on different contributing parameters such as orientation, construction materials, type of construction, height, and architectural design. The results show that using alpolic cladding and double-layered windows at the outer face of buildings increases thermal efficiency by 8%. The cavity wall construction improves the energy conservation of the building by 6% compared to traditional block construction. The model studies show that using cavity wall and structural concrete insulated panels (SCIP) as cladding/infill walls in frame structures can reduce the energy demand of the building up to 3%. Simple techniques such as altering building orientation, architecture, use of the latest energy-efficient insulation materials, and enhanced construction techniques contribute significantly towards energy efficient and sustainable performance of buildings.
