PassivHaus is the world’s leading standard in energy efficient construction.  It is an internationally recognised standard which can be applied to different building types. 

A PassivHaus building is one in which a comfortable interior climate can be maintained throughout the year without using active heating or cooling systems.  Buildings using PassivHaus techniques can save up to 90% of energy demand. 

SRE provides specialist PassivHaus advice for clients seeking to develop buildings with exemplar levels of energy performance.  With a fully trained PassivHaus consultant within the SRE team, this specialist approach can be combined with other project requirements including Renewable Energy Feasibility and BREEAM/CSH.
