The first ‘Passivhaus’ low energy construction standard is credited to Dr. Wolfgang Feist of the Passivhaus Institut, Germany. The first Passivhaus being completed in Darmstadt, Germany in 1990.
Passive Houses” were defined as buildings which have an extremely small heating energy demand even in the Central European climate and therefore need no active heating. Such houses can be kept warm “passively”, solely by using the existing internal heat sources and the solar energy entering through the windows as well as by the minimal heating of incoming fresh air.
The following PDF downloads provide some useful informarion on the Passivhaus standard, along with the recently published ‘EnerPHit’ standard that seeks to apply Passivhaus design principles to existing buildings:
- Passipedia – Passipedia constitutes a vast array of cutting edge, scientifically sound, Passive House relevant articles. Passipedia is the tool with which new Passive House findings from around the world are being presented, as well as where the highlights of more than 20 years of research on Passive Houses are being posted, often for the first time ever in English.
- Passivhaus Primer: Introduction – An aid to understanding the key principles of the Passivhaus standard
- Passivhaus Primer: Designers Guide – A guide for the design team and local authorities
- Passivhaus Primer: Contractors Guide – Addresses the issues that building contractors face when tasked with a Passivhaus project and gives simple advice and tips on how to deliver a successful outcome.
- Certification Leaflet – Outlines the difference between a Passivhaus dwelling and a Passivhaus unit and how to consider mixed use developments.
- Passivhaus Certification Criteria: Residential – Outlines the certification and evidence requirement for the residential Passivhaus Standard
- Passivhaus Certification Criteria: Non-Residential – Outlines the certification and evidence requirement for the non residential Passivhaus Standard
- EnerPHit Certification Criteria: Residential Refurbishment – The EnerPHit Standard has been developed as a good practice refurbishment guide for Passivhaus renovations. EnerPHit recognises the difficulty of achieving a full Passivhaus standard in existing buildings without excessive cost or intrusion to the existing building. Hence EnerPHit has set a slightly different standard requirement to the full Passivhaus standard
