Researchers of the University of Luxembourg have the aim to develop a building concept for their new university buildings with low energy consumption and a high thermal comfort. To achieve these objectives it was necessary to develop a concept ensuring tolerable room temperatures without mechanical ventilation and air-conditioning based on low electricity consumption for lighting and office equipment.The new main building “La Maison du Savoir” of the University of Luxembourg was simulated dynamically by means of the software tools TRNSYS and TRNFLOW. Furthermore, daylight simulations were performed, because special façade elements were imposed by the architects, and measurements of test installations were done to optimize the internal loads from lighting. Through this optimization of the windows considering the effects of daylight and solar radiation in the summer period, energy saving effects by the lighting of 50% are realistic.The night ventilation reaches the highest cooling effect of all analyzed means. As the opening of windows is not mechanically controlled, a heightened awareness on the part of the user is assumed for an effective realization.Separate calculations of the annual heating demand were done and result in a theoretical heat energy consumption of 12 kWh/m3a (48 kWh/m²a). The optimized electricity consumption of lighting, domestic hot water and auxiliary energy is approximately 4,5 kWh/m3a (18 kWh/m²a) in the office part of the building. These values comply with the limit values according to the internal guidelines of the University (Maas et al., 2008). But in case mechanical ventilation and airconditioning were used, these limits could not be respected anymore.The thermal comfort in the office rooms of the “La Maison du Savoir” is ensured according to the future regulation of Luxembourg for non-residential buildings, if all suggestions are going to be realized.

    盧森堡大學的研究者有,目的是制定其新大學建築與低能耗和高舒適性的建築概念。為實現這些目標,有必要制訂確保沒有機械通風和空調基於低電力消耗的照明及辦公設備可以忍受房間溫度的概念。新的主建築"La Maison 杜能力"的盧森堡大學是動態類比通過 TRNSYS 和 TRNFLOW 的軟體工具。此外,夏時制類比被執行,因為特別的正面因素強加的建築師、 測量測試設施,都是為優化的內部載荷從照明。通過這種優化的考慮夏時制和夏季時期的太陽輻射效應的 windows,由 50%的照明節能效果是現實的。夜間通風達到最高的冷卻效果的所有分析手段。由於開放的視窗不機械地控制,有效實現假定使用者提高的警覺。每年的供暖需求的單獨計算進行了,導致 12 千瓦時/m3a (48 千瓦時/m²a) 理論熱能源消耗。優化的電力消費的照明、 生活熱水和輔助能源辦公室地區是建築物的大約 4,5 千瓦時/m3a (18 千瓦時/m²a)。這些值符合根據大學 (Maas et al,2008年) 的內部指引的限制值。但在的情況下使用了機械通風和空調,這些限制不能再也尊重。如果所有建議都將要實現在"La Maison 杜能力"的辦公室房間熱舒適被確保根據盧森堡非住宅建築的未來規例。溫度的分析

    不要跟我說你是高科大營建系 建築物裡的作業

    該不會是吧 哈哈
