passive house (passivhaus)

Oliver Kaminski is a Certified Passive House Designer, bringing specialist energy efficiency knowledge to the practice.

Passive House design seeks to reduce dependency on fossil fuels and is the fastest growing energy performance standard in the world . This is primarily achieved through excellent thermal performance, air tightness and heat recovery through mechanical ventilation.

The Passive House Standard was evolved in Germany in the early 1990's and currently there are over 30,000 passive house buildings worldwide. The UK has few. This is changing however, as environmental and fuel poverty concerns rise.
