由於科技日益發達，經濟不斷提升，人們對於生活品質及健康與舒適的生活環境的需求也逐漸提升，進而對能源的需求也不斷增加，造成許多的環境衝擊，尤其地球暖化日益嚴重，使得環境保護與節能減碳成為全球最關注的議題，建築物的能源使用效率亦逐漸成為現今之熱門議題。因此，本研究提出之最佳化模型配合三種相關設備的使用以提供使用者維持一定熱舒適水準，同時達到最小化之能源消耗。
本研究提出之最佳化模型基於實際情況，經由利用相關之環境與個人資料和設備條件以及使用者輸入之期望PMV值，能提供使用者一組最佳設定溫度與相對濕度以及冷氣、除濕機與加濕機的操作策略。藉由不同設備組合的使用策略，可達成維持使用者期望之熱舒適水準，同時最小化能源之消耗。

Since the development of technology is growing rapidly, and economic level are enhanced continuously, people started to raise their requirements of life quality, and a healthy and comfortable environment. However, while the economy and technology evolve, the continuously raising demand of energy causes many impacts in the ecology environment, such as global warming. As the result, the issue of ecology environment protection and energy saving become the most concerned part for the entire planet. Due to the growth of energy costs, energy consumption and environmental impacts, energy efficiency in buildings become an important issue nowadays. Therefore, the purpose in this study is to provide an optimization model that can reduce the energy consumption while maintaining the indoor thermal comfort.
In this study, we have proposed an optimization model based on a variety of practical situation. The system will use the relevant data detected through the environmental and personal sensor, or manually input by user, and then user will give the equipment condition and an expected PMV value to run the model. Finally, the model will provide the optimal set-point of temperature and relative humidity and the operating strategy of air conditioning, dehumidifier and humidifier. By arranging different combinations of these apparatus, we can achieve the reduction of energy consumption while maintaining a certain thermal comfort level.
