Abstract

The purposes of this research were studying the use of computer programs to help design and simulate situations to support energy management in school buildings, finding a guideline of reducing the heat through the building according to the law, also providing the information supporting of deciding of owners in energy management in the building. The scope of research was the air-conditioned section area of the school building, Faculty of Industrial Technology, Suan Sunandha Rajabhat University. The research method was ISA’s OTTV52 program for calculating the heat value through the building and Google Sketch-up for simulating of building environment design. Methods of conducting research by surveying physical measurements of buildings and electrical system equipment, recording the temperature and illuminance value and using to simulate the design and result from analysis. The results found that the school building has total electricity consumption of 349,542.12 kWh per year. The total heat value through the building frame exceeds the standard value, especially in the northwest. This research suggests that is the building walls should increase the air gap, attaching polyethylene foam and gypsum board to the surface with gypsum plaster and changing window glass film. Moreover, metal sheet roofs are proposed to spray white foam insulation on top to insulate and increase heat reflection. That result was resulting in the total heat value through the building frame is greatly reduced. This research has simulated for installed ivy garden in vertical in order to receive the heat from the sun directly which the ivy panel has a thick bush. It will assist in reducing the heat into the building frame, reducing the usage of air conditioning and make room temperature almost in a comfortable area. This natural technique is to manage energy in sustainable buildings, low-cost, and creating a shady place for buildings.
