Apos Petrakis, senior architect at Impington based Archangel Architects has achieved Passive House Designer accreditation. Passive House or Passivhaus is the world’s leading fabric first approach to low energy building. It dramatically reduces heating and cooling requirements, whilst creating excellent indoor air quality, comfort and health.  It is a rigorous voluntary standard tried and tested on over 37,000 buildings worldwide for over 25 years. The standard is equally suited to retrofits.  After successfully participating in the Passive House Institute’s Certified Passive House Designer/Consultant examination, Apos is now a Certified Passive House Designer. 

Archangel Architects are increasingly focused on delivering long-term sustainability and as certified European Passivhaus Designers can design your new home or any building to one of the three Passivhaus Standard, classic, premium or plus; or if retrofitting existing buildings, to the EnerPHit standard. The Passivhaus Standard is a construction standard developed by the Passivhaus Institute in Germany for highly energy efficient buildings utilising passive solar energy using windows that take in more heat energy than they lose (triple glazed with a window U value of less than 0.8W/m²K). The standard can be met using a variety of design strategies, construction methods and technologies and is applicable to any building type.

Apos is an Associate and a chartered architect trained in Germany with 12 years’ experience in residential and cultural projects. He has completed an MSc in Environmental Design from the University of Cardiff, and leads Archangel’s implementation of energy efficiency and sustainability.
