Résumé

The thermal comfort of the residential buildings LichtAktiv Haus in Germnay and Sunlighthouse in Austria is investigated with a particular focus on the strategies used to achieve good thermal comfort, and the role of solar shading and natural ventilation. The houses were completed in 2011 as two of six buildings in the Model Home 2020 project. They have very generous daylight conditions, and are designed to be energy efficient and CO2 neutral with a good indoor environment. The living rooms in both houses have generous daylight conditions and have been selected for the detailed analyses for this reason. The thermal environment is evaluated according to the Active House specification (based on the adaptive method of EN 15251), and it is found that the house reaches category 1 for the summer situation. Some undercooling occurs in Sunlighthouse during winter, causing the room to achieve category 2 if the entire year is considered, while LichtAktiv Haus maintains category 1 when undercooling is included. It is found that ventilative cooling through window openings play a particularly important role in maintaining thermal comfort and that both window openings and external solar shading are used frequently.
