The purpose of this research study is to develop decision-making tools for energy saving house that corresponded with the cost of construction  within four energy saving assessment   frameworks in Thailand.  The results reveal that building envelop holds the most significant from all four assessment.  The significant impact of the building envelops record between 23-40% in all of the evaluations approximately 66-88% of the bottom line score. The principle of the building envelops is to classify the property of the material which exhibits high heat resistant quality . The fundamental of the building envelops is to analyze the property of the material, which exhibits high heat resistant quality.  The main source of the research is from TEEAM evaluation, which recognizes three property of building envelope glazing type, materials of exterior and materials of ceiling insulation.  Through the measuring of the energy efficiency data to the sample house, the results suggest four performance classes of energy saving efficiency simultaneously with the increase of construction cost. The lowest performance class (D Group) provide 8% more in energy efficiency with an increase of 5% of the initial cost and Internal rate of return at (IRR) 21%.
