This research approach to study the development of interior wall for reduce energy consumption by air conditioning in the building. In order to be a prototype in the development of an industrial system for the export of green architecture in order to generate income for the community or entrepreneurs to bring money into the country to upgrade the industrial economy to be sustainable It is an architectural material that is compatible with the weather in Thailand. It can be used as a guideline for people interested in applying it to their own home building or disseminating through various media to reduce energy costs for a comfortable living. The objective is to study the factors that affect the development of wall paneling in order to reduce the energy burden of the air conditioner in the building in order to further the commercial production. The researcher collected data for the past 6 months not including other thermal energy. Used to calculate the energy consumption index for 2 building groups it was found that the electricity consumption of green buildings were 531100 kilowatt hours. And an average of 5.31 kilowatt hours per square meter While the non-green building has an average of 653360 kilowatt hours. And an average of 6.53 kilowatt hours per square meter As for the results of the data analysis the damage level is mostly at level 1 which is the wall surface and no obvious damage. Especially the 4th and 5th height is 1.55 meters and 1.85 meters from the floor level in the building. Damage level 3 is found at the height level 3 at a height of 1.00 meters from the floor level in the building. Assessment of damage caused to the interior wall of the building that occurred in 3 levels. The results of the data analysis showed that most damage levels were at level 1 namely the wall surface without obvious damage. Especially the 4th and 5th height is 1.55 meters and 1.85 meters from the floor level in the building. Damage level 3 is found at the height level 3 at a height of 1.00 meters and from the results of collecting moisture content in the exterior wall materials And analyzed to find the average for each of the 5 levels of height which are 0.55 meters 0.75 meters 0.95 meters 1.55 meters and 1.85 meters found that the buildings have different moisture content in each wall level (p <0.05). In conclusion this green building index equation can be applied to other buildings to reduce energy consumption and meet the standards of the green building. From the equation the electricity consumption can be predicted using the electricity usage index and systematically designed energy management in buildings. The area with the most damage will find the humidity in the range of 47% -98% the highest damage level 3 at an elevation of 0.80 meters from the floor level in the building

This research is the development of an energy - saving water planting kit. The objective is to develop a prototype of an energy - saving water planting kit by applying solar energy as an energy source that is controlled by the Arduino board through a blynk application and study the efficiency of the water culture planting kit. By comparing electricity usage rates between solar energy and electric power from the household. In this study there were 4 experimental sets. The experiment was water cultivation without installation 2 experimental sets and 2 experimental sets were installed using green salad vegetables. In research the 45 days growth period consisted of leaf length and width root length number of leaves and height. There is also a comparison of the efficiency of AB fertilizer and soy milk hormones to reduce chemical usage. The research has shown that the use of the soybean milk hormone provided a high growth rate of Lactuce sativaVar. Longifolla than AB fertilizer. There are many nutrients but only in small amounts. When used as a nutrient for plant growth needs to be changed daily. Considering the economic value using AB fertilizer as a nutrient will be worth more than soy milk hormones. For the installation of the instruction set and the LED lamp was suitable for Lactuce sativaVar. Longifolla growing than not installing the instruction set and the LED lamp. These can save electricity cost of 85 baht per month.

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 aim of this research was to develop recipe for butter cake from lowcalories sweeteners instead of sucrose sugar chemical properties of butter cake from low- calories sweeteners instead of sucrose sugar and to study the physical properties of butter cake from low-calories sweeteners instead of sucrose sugar. The use of maltitol syrup to replacement sucrose butter cake low-calories show that 36.28% to 42.47% of carbohydrate content. Decrease in carbohydrate content results in reduced calories. Cake crumb show that the b* value decreases significantly and the a* value is not significantly different. The texture of the butter cake has a higher in hardness and lower in cohesiveness. The Adhesiveness and Springiness are not different. The sensory evaluation scores of butter cakes ranged from 6.95 to 8.61. Appearance color aroma flavor texture and overall liking. The results showed that 40% and 60% of sucrose substitutes were sucrose substitutes. The 80 on all the attributes especially on the flavor. However the use of maltitol syrup substitutes for sucrose. As a result the amount of energy of the butter cake decreased which is beneficial to the health of consumers.

Defrosting at evaporator panel is one of working cycles in freezer. Power consumption in defrosting does not meet the objective of using freezer therefore the approach to decrease power consumption in defrosting is one strategy for energy saving. Normally the cycle of defrosting in freezer is a constant time that specify by referring to the highest humidity period. With this control concept the problem of temperature exchange is not occurred from ice accumulation at evaporator panel but it makes the over necessity of defrosting process in the low humidity season and cause the unnecessary power usage in freezer. This research presents the control approach for defrosting by using the difference of the temperature at evaporator and the temperature at chilling area. By using this approach the defrosting process is operated depend on load and the fan is on or off relate to defrosting time. Test results demonstrate that about 12% of power can be saved by this control approach when compared to constant time control.
