solar shading

The Kindergarten Solhuset is built according to the Active House vision with an emphasize of good daylight conditions and fresh air. The house was completed in 2011, and detailed measurements of the indoor environment have been performed since the completion. The daylight performance is evaluated with daylight factor simulations. The main activity rooms have daylight factors of 7%, while the innermost rooms with only roof windows achieve a high daylight factor of 4%. Electrical light is used frequently in daytime during the winter, but much less frequently during summer.

The thermal comfort of the “Home for Life” dwelling in Denmark, the “LichtAktiv Haus” in Germany and “Sunlighthouse” in Austria is investigated with a particular focus on the control strategies and the role of solar shading and natural ventilation (ventilative cooling). These houses are three of six buildings in the Model Home 2020 project (Feifer, 2013). They have generous daylight conditions, and are designed to be energy efficient and CO2 neutral with a good indoor environment.

The thermal comfort of the residential building Home for Life is investigated with a particular focus on the strategies used to achieve good thermal comfort, and the role of solar shading and natural ventilation. Home for Life was completed in 2009 as one of six buildings in the Model Home 2020 project. It has very generous daylight conditions, and is designed to be energy neutral with a good indoor environment.

Motorized sun-controlled louvers and electrically heated glasses are installed in NIKKEN SEKKEITokyo Bldg. A lot of highly effective equipment systems are set up in this building. In this research,these energy conservation systems are measured and analyzed. This report explains the specificationof the building, equipments, and the window system. . As a result, it was confirmed that the exteriorblinds and a heat generating double glazing was effective in keeping thermal environment comfortableand saving energy.

Solar shading devices can significantly improve thermal comfort and reduce cooling loads and potential glare problems in highly glazed buildings. This paper describes results from an extensive measurement program that started in 1997, covering external shading devices, products placed between two panes (interpane), and internal shading devices. Measurements of the total solar energy transmittance (g-value) have been performed using a double hot-box arrangement placed in a real climate.

In Switzerland, even if the average daily temperature rarely exceeds 25º C during the summer months, more and more cooling plants are being installed in administrative buildings. The CUEPE participated as experts in some realisations that showed (simulat
