This document discusses sustainable passive houses for both old and new buildings. It highlights that retrofitting existing buildings to the passive house standard can result in energy savings that pay back the additional costs within 5-11 years. New buildings can also be constructed to the passive house standard to minimize energy usage from the beginning. The passive house standard is presented as a strategy to address economic and environmental issues.

Official journal of EU published on 2010-06-18
“Utilize all energy efficiency potentials
of buildings”
All new buildings must be
“Nearly Zero Energy Buildings” at least by 2020
That implies:
– new build must comply Passive House Standard
at least
– minimal residual energy demand must be
covered with renewable energy
At retrofits max. efficiency potential shall be used
