This research was a study of energy management in public building. The goals of this project are to decrease energy consumption and to enhance energy management system of the building. Regarding the energy survey the building lights are turned on for 24 hr. per day in order to satisfactorily serve the customers. In the study it was found that the energy consumption of electric light on the fourth floor roof can be reduced by changing the light “Floodlight MH. 4x250W” to be “High bay LED 4x150W” For the merit this project can save the energy around 6632570 baht per year and switching towards high-efficiency lanterns and replacing FL. T8 light bulbs installed in the walkways with FL. T5 models. This reduces lighting cost by 361425 baht per year. Moreover the energy management system was analyzed by using SWOT Analysis. As a result we observed the barriers to communication must be overcome to promote energy conservation. One approach is to increase the performance through the use of communication strategies within organizations. This method will help align employees understanding and participating in activities of conserve energy.

This research had an aim to develop an autoclave for using in natural dyes extraction and dyeing process. The autoclave used the stainless steel as the major material what it was a noble durable material and good resistance for the chemical used in the processes. The achievement results showed by the comparison data between the conventional process and the development using autoclave in term of extraction efficiency deep of shade (K/S) time equivalent process time and amount of gas consumption saver. The knowledge from the research would transfer to the target group at Bann Yang Nam Klad Tai Phetchaburi province. The results were following as 1. For the extraction process: the extraction process using 100oC for 45 min. They obtained product was the same dye quality but the autoclave process was smaller water evaporation as 26.71% whereas the conventional process was 41.99%. 2. For the dyeing process: All condition from the autoclave using make a deeper dye shade (K/S) than conventional process. The dyeing time equivalent as 15 minutes to make the depth shape via autoclave process as alike the conventional process for 45 min. 3. Saving time and gas consumption: the autoclave process could save 66.67% time process and 88.99% amount of gas consumption. 4. The Complacency for knowledge assignment: the satisfaction level in the content time and period was good. Furthermore the utilization the instructors and the value obtained were excellent. This research accomplished the study objectives. The results were not only corresponding to energy conservation but them also reducing the chemical toxic and pollutant vapor inhalant to the worker.
