Thermal Comfort—Case Study in a Lightweight Passive House

Saving energy while maintaining a high-quality internal environment is an increasingly important scientific and technological challenge in the building sector. This paper presents results from long-term study on thermal comfort passive house situated south of Poland. The was constructed 2010 with use prefabricated, lightweight technology. main source ground heat pump which powers floor heating DHW. also equipped mechanical ventilation system recovery exchanger. A structure has active systems limited capabilities (especially for cooling) combination increases difficulty proper inner environmental condition. Extensive experimental investigations hygrothermal performance have been carried out several years. measurement results, such as air temperature humidity, well surface partitions, could be directly used to determine basic indicators, including PMV PPD. Any missing data that not measured, windows, floors, some other elements envelope, calculated using WUFI®PLUS software validated available measurements. These are final; full applied methodology did consider human adaptation assumed constant clothing insulation. Nevertheless, general, show good conditions inside under research conditions. confirmed via survey inhabitants: 2 adults 3 children.
