maja, mille energiavajadus on viidud miinimumi looduslike kütte-, valgustus- ning jahutusvõimaluste abil, energiasäästlik maja
building that does not rely on the installation of active mechanical heating, cooling or ventilation systems to ensure a comfortable, healthy indoor environment
a house built in accordance with the Passivhaus energy efficiency standard
Hea teada
The passive house standard was defined in 1988, and the first passive house was built in Darmstadt in Germany in 1990.
Passiivmaja kasutab ära asukoha looduslikke kütte-, jahutus- ja valgustusvõimalusi, nii et ehitise energiavajadus on viidud miinimumini, mikrokliima on tervislik ning vajadus kunstliku valgustuse, ventilatsiooni, kütte ning jahutuse järele minimaalne, ilma selleks päikesepatareisid ja tavapärast soojuse akumulatsiooni süsteemi kasutamata.
All airtight buildings (any low-energy building needs to be airtight), except those in so called “lucky climates”, require the use of an efficient ventilation system. In Passive Houses this system can also be used for heating purposes, without the need for additional ducts, major technical interfaces, auxiliary fans etc.
