About the Passivhaus Standard:
The term “PassivHaus” refers to a specific building construction standard with excellent comfort conditions during summer and winter. Such buildings reduce space heating by 90% and total energy consumption by 75-80% compared to UK Building Regulations and achieve a comparable reduction in carbon emissions. The Passivhaus Standard was developed in the early 1990’s by Professor Wolfgang Feist and Professor Bo Adamson and then launched in 1996.
The Passivhaus Standard, the worlds leading quality assurance standard for low energy building, is over 20 years old and there are now reported to be more than 50,000 Passivhaus buildings globally – including houses, apartments, schools, offices, sports halls and gymnasiums, sheltered accommodation and care homes, hospitals and medical centres.
The exemplary performance of Passivhaus Standard has been documented extensively through ongoing scientific research. In parallel research has revealed that there is a significant gap between the theoretical performance of sustainable low energy dwellings and the actual delivered performance. This often means carbon emissions savings are not being delivered in practice. Recent papers, including a paper prepared by the architet of Steel Farm (http://www.mdpi.com/2071-1050/8/1/97/pdf), demonstrate that houses build to the Passivhaus Standard are capable of closing the performance gap.
