Abstract

Nowadays, the trend of climate is highly increased. Therefore, air conditioner was widely installed in residential building for adjust the Thermal Comfort. On the other hand, the electric appliance has highly an effect on electric fee. For this reason, the chosen material was used in construction as well as wall and ceiling, which protect the heating of sunlight from outside into inside of residential and reduce electric fee. In this research aims to evaluated of the assembly material that appropriate and various of ratio in the heat resistance and low cost condition using value engineering for creating BIM model. The software (Autodesk Revit and Autodesk Ecotect) was analyzed in this paper. In the part of selected material was chosen the acceptable material of consumers and commercial construction material. The design of wall and ceiling was changed the position, type of material in each of layer of wall and ceiling. After that, the verities of designed patterns were installed and test to residential building model. According to the experiment can be examine the temperature at the time of use and amount of electrical energy due to usage. As the result of the walls in the afternoon, the lowest temperature of wall is brick wall with 2 sides sand plaster. The best of heat protection of wall with installation of air conditioner is lightweight concrete wall, with 75 mm of thickness and 30 mm of gap in the middle. At the night time, the appropriate wall with installation of air conditioner is lightweight concrete wall with 2 sides plaster. In the part of ceiling, it found that thermal insulation (Stay cool) 150 mm of thickness can be protecting the heat of sunlight. In addition, the analysis data is increasing of 10.28% of the constructing cost, reducing of 17.01% of electrical fee and 20 years of the total lowest cost.
