Sustainable building standards integrating energy efficiency and health science thermal comfort

Abstract

This research aimed to improve energy efficiency in electricity demand during Thailand's summer (March-May), when consumption significantly exceeds the annual average. The study integrates energy efficiency and health science by focusing on indoor thermal conditions that support both reduced energy use and the health and well-being of people, particularly those vulnerable to heat stress due to reduced thermoregulation. The study investigated thermal comfort in air-conditioned rooms with energy-efficient usage by adjusting temperature setpoints and using electric fans to enhance air circulation. Experiments were conducted in an office under a tropical climate, with temperatures set between 27-30°C, compared to a baseline of 25°C without a fan. Results showed that a 27°C setting combined with a table fan provided thermal comfort comparable to the baseline. Improved air movement enhances heat dissipation, supporting human thermal regulation. This approach reduced energy consumption by 26%, effectively lowering peak demand. The findings highlight that optimizing temperature settings with adequate air circulation can achieve both energy efficiency and health science outcomes, promoting sustainable and comfortable indoor environments for people, especially aging populations.
