The results of the analysis indicate that both 2 cases. Material selection structure energy saving can reduce the overall heat transfer of the building and the roof than the use of structure building materials that do not use energy-efficient appliances. So, changing from material structures that do not use energy-efficient appliances. A structural material energy saving Can help to reduce heat transfer with a payback and value in economics faster.
From the results of the study showed that when changing building structure materials, which do not use the device to save energy as the energy-saving materials that would have costs increase because the original building structure materials, which do not use energy saving equipment with cheaper materials of construction energy-saving. Because of the use of auxiliary equipment in the building structure reduces the heat into the building, so the price is higher. Simply comparing term payback and value the way economics of the use of the accessory in the structure. Appropriate value to investors
