The HAp's Contribution to Optimising an Administrative Building's Thermal Loads and Energy Efficiency

Article Preview

Abstract:

Enhancing the energy efficiency of administrative buildings is a critical factor in advancing global energy sustainability. This research introduces a methodology for refining thermal loads and minimizing energy consumption through computational simulations using the HAP (Hourly Analysis Program) tool. The primary goal is to transform an energy-demanding administrative structure into an environmentally sustainable and high-performance facility. A comprehensive assessment of the building’s initial state uncovered structural inefficiencies influencing its energy demand, particularly regarding insulation, air circulation, and lighting. By incorporating advanced architectural and engineering solutions, including upgraded insulation, LED lighting implementation, and optimized HVAC system configurations, the findings indicate a considerable reduction in energy usage. This study emphasizes the necessity of integrating ASHRAE regulations and computational simulation methodologies in advancing building energy performance.
