A Field Study on Thermal Comfort and Cooling Load Demand Optimization in a Tropical Climate

Energy consumption to cool an indoor environment is a substantial part of total energy end-use, particularly in a tropical climate with high energy demand for cooling. To improve energy efficiency, cooling systems can be optimized using a variety of neutral indoor temperatures to maintain a balance...
