PhotoJapanese government declared goal of achieving carbon neutrality by 2050, to achieve this target the Ministry of Energy has proposed the BI-Tech project, which aims to help raise awareness of energy conservation among building occupants through AI and IoT technologies. In this study, we focus on the users’ air conditioning set-point temperature and energy-saving behaviors and developed a low-cost system for real-time monitoring & prediction of indoor thermal comfort and air conditioning energy consumption based on BI-Tech, calculating thermal comfort in real time and predicting air conditioning energy consumption based on user’s set-point temperature changes and evaluate the indoor healthy office environment in real time uploading data to App interacting with users, to raise the users’ awareness of energy saving and achieve energy-saving behavior.
夏季は自然に冷却・除湿し、冬季は太陽集熱する熱性能可変型PDSC外被システムの性能向上を目途に、PDSCとERV(全熱交換換気)を併用したPSE(再生可能エネルギーと全熱交換を活用したハイブリッド換気システム)の省エネルギー効果について検討する。これまでに行ったPSEの数値実験結果を基に、汎用製品化を目指して実際に民間企業とPSE機器を共同開発する。更に、実証住宅による屋外実験と数値シミュレーションによりPSEの通年に亘る効率的な運転条件や方法について検証し、最適な制御システムを設計する。
