Nollaenergiarakennus
“A nearly zero-energy building is a building that has a very high energy
performance. The nearly zero or very low amount of energy required should be
covered to a very significant extent by energy from renewable sources,
including energy from renewable sources produced on-site or nearby”
(Article 2/EPBD recast)

3. 38/23/13
Nollaenergiarakentaminen
§ Rakennuksen energiantarve riittävän pieneksi varmistaen hyvä
rakennusfysikaalinen toiminta ja hyvä sisäilma
§ Energian tuotanto rakennuksissa/alueella lisääntyy
§ Energiantarpeesta katetaan merkittävä osa talossa tai sen
läheisyydessä tuotetulla uusiutuvalla energialla
§ Energianvarastointi ja kaksisuuntaiset energiaverkot tulevat
tärkeämmiksi

Uudet eristemateriaalit
Aerogel, the lowest thermal conductivity ever known lamda< 0,012W/mK in ambient conditions
The main goal of the AEROCOINs project is to develop a new
composite/ hybrid aerogel material to improve the thermal insulating
performance of existing buildings aiming at reducing their energy
demands.
