Comparison of Construction Systems and Materials Affecting Temperature and Virtual Feeling Inside the Building: Case Study of Nordic Style Prototype House, Bang Phra Subdistrict, Chonburi Province

Abstract

This research aims to compare the construction systems and materials affecting indoor temperature and feeling inside the building. The case study is a Nordic-style prototype house in Bang Phra Subdistrict, Chonburi Province, designed to enhance energy efficiency and quality of life. This research selected to use the floor - wall - roof system by studying three scenarios: (1) Lightweight brick structure 2. Steel structure covered with lightweight cement fiber walls and (3) Prefabricated insulation panel system. The popular construction systems in Thailand, such as lightweight brick structures and steel structures covered with lightweight cement fiber walls, result in high internal temperatures and high energy consumption, causing discomfortable feelings when stay inside of the building, which is unsuitable for Thailand’s climate.This research found that the Case Study 3, which is the prefabricated insulation panel system, has the best heat insulation value. The temperature and the feeling of being in the best comfortable condition are with the heat value: Case Study 1 measured temperature of 30.64 °C, the feeling of being 32.89 °C; Case Study 2 measured temperature of 31.06 °C, the feeling of being 33.47 °C; and Case Study 3 measured temperature of 26.00 °C, the feeling of being 26.40 °C, respectively. The construction of the prototype building in this research has developed knowledge, using a system of floor panels, walls, roofs, and prefabricated insulation, reducing construction steps, reducing time, and labor from the original construction. It is a system that allows the building to save energy to the maximum, can be completed within 5 days. It demonstrates excellent heat and moisture resistance, as evidenced by real-world experimental results. Data was collected on heat levels, ambient temperature, radiant temperature, and perceived temperature (Physiological Equivalent Temperature). The conclusion is that when Nordic-style houses are integrated with energy-saving designs and appropriate technologies, they can effectively adapt to Thailand's hot and humid climate.
