Professor Wolfgang Feist is the Founder of the Passive House concept and the Passivhaus Institut in Germany. He first developed the term ‘PassivHaus’ in the 1980’s to refer to a voluntary, ultra low-energy construction standard for residences intended to dramatically reduce the requirement for space heating and cooling. Since then, the Passive House concept has become the fastest growing low energy standard in Europe and has seen widespread adoption, with over 25,000 structures completed to date.
Steff Bell is a certified Passivhaus designer. He was introduced to the Passivhaus standard while working in Germany with Herz & Lang GmbH and obtained his Passivhaus qualification through the Certified European Passivhaus Designer Course (CEPH) at the Energieinstitut Vorarlberg in Austria. Since his return to Scotland, Steff has been working with the Scottish Passive House Centre (SPHC), helping to implement the Passive House standard in the UK through his work with the SPHC, research/development, article work and lecturing.
