Energy Efficiency and Economical Analysis of Constructions Materials for Controlled Buildings in Thailand

S. Phetcharat
Abstract—Comparison of heat transfer reduction efficiency of construction materials and its economical worthiness was performed for materials popularly used in the construction industry in Thailand. Heat transfer through walls and roofs on the southern side of a model constructed according to the criteria and specifications for controlled buildings in the category for offices and educational institution as announced by the Ministry of Energy. Economical analysis results show that foam cellocrete is the best wall material for heat resistance properties with an OTTV value of 18 W/m2 but lightweight concrete is more cost effective with a B/C ratio of 2.93 and a payback period of 1 year and 7 months. For the best concrete block arrangement, double walls with gap, has B/C ratio value of 2.56. Light screening film on glass or double glass walls help to lower the heat transfer rate but not to the required 50 W/m2 by the Ministry of Energy. Thus, it should be integrated with other materials at the appropriate portions. For roofing materials, the best material for heat insulator is polyurethane foam but the most cost-effective material is polystyrene foam with highest B/C = 1.12 and a return period of 4 years and 5 months.

Index Terms—Construction materials, energy conservation, controlled buildings.
