Presently Rental office is famous in downtown that near food center and have good transportation. In Thailand office buildings usually have operating time 8-10 hours per day. So need to improve the building for energy conservation and employee’s comfort. Glasses are one way that heat transfers occur highly. Overall Thermal Transfer Value (OTTV) is a tool for measure heat transfers through building envelope. From OTTV calculation for existing building OTTV is 92.94 W/m2 that over ministerial regulations indicate 50 W/m2. Improving building envelope by add more thickness of glasses can reduce OTTV 1.3% and improving building envelope by film installation can reduce OTTV 47.2% and improving building envelope by add shading can reduce OTTV 48.5%. However each improving policy have each investment cost. Conjoint analysis is consider of many factor to find willingness to pay for each choice. So set policies for energy conservation water and waste management and increase comfort are employees to improve energy conservation water and waste management and increase comfort are 19935.90 17590.50 and 1563.60 baht respectively so can improve building envelope by add shading result in OTTV to 47.8 W/m2 Budget 18000 Baht can be improve organization that payback about 5400 Baht per year. Increase thermal comfort by install table fan. From the result of research expect to apply to improve rental office in the future.

The research aims to study and develop the Kaolinite mixed with cement powder for the mass wall. The Kaolinite development process to improve the characteristics. The Kaolinite mixed ratios are 10% 20% 30% and 40% and the result indicated that the experiment mortar-mix ratio at 0:8:2.75:0.2:0.05:0.04:0.5 of cement powder sand Kaolinite limestone superplasticised and clean water compared to No MK control sample covered ASTM standard in tensile strength more than 100 ksc compressive strength of MK20% with superplasticised at 434 ksc. The water absorption values under the standard passed

This research aims to study and test a ceramic product in using to constructs a wall. This research is based on a previous studying to develop a ceramic product that saves the energy in the building. The early test shows the product has out door heat resisting capability and it is very user-friendly. However the test was only an early stage. The research still lack of a real life situation test and has very little feedback from the consumers. All of which are very importance to farther develop this product into a production stage. The research has 2 steps. First step to testing the heat and humidity resisting quality of the product the researcher is building four testing blocks (dimension 1x1x1 meter). Each block has different material on one of its side block 1 has brick block 2 has concrete masonry unit block 3 has autoclaved aerated concrete and block 4 has ceramic block. The other three side of each block have a heated and humidity resisting form. The researches test the following; heat energy the temperature inside the blocks and humidity inside the block. After comparing the difference between the airs inside and out-side of the blocks the block 2 with concrete masonry unit has the best humidity resisting quality and is the most user-friendly product. In the term of heat resisting block 3 with autoclaved aerated concrete perform the best. Second step to test the user-friendliness of the product the researcher found 2 groups of consumers. First group are the wall constructing expert. This group has a hard time using this product and can’t get use d to the product so they find this product to be too thin and too weak. Second group the home owner feel the product has a thinner wall and believe it’s weaker than a typical construction brick. There for they still don’t know how to use this product.

Currently the toy manufacture is beginning to be interested in greenhouse gas or carbon dioxide equivalent release reduction. Because this is one to way to encourage production cost environment trouble and organization image valve efficiently. The receivable standard for evaluation is carbon footprint for Organization CFO. So this research has objective to study opportunity for initiate CFO in Toy Manufacturing plant case study this CFO is able to evaluate energy consumption and GHG release systematically. This can be used to prepare plan of energy consumption reduction management and reduce GHG release of efficiently. This research was study energy consumption and GHG release by using database of 2010 we found that plant case study was released carbon dioxide 8500 tons CO2 carbon dioxide equivalent by calculated into Scope 1 = 1249 tons CO2 Scope 2 = 6948 tons CO2 equivalent and Scope 3 = 304 tons CO2 equivalent. So the result from this research is being uses important information for planning energy consumption reduction and GHG release of sustainable case study.
