What is Passivhaus?
Passivhaus is a leading international low-energy standard for buildings. First developed around 20 years ago, it has been generating much more interest in the UK over the past five years or so.
It is based on sound building physics to reduce energy consumption by design, and results in simple, robust, long-lasting and energy-efficient buildings.
A Passivhaus building uses typically around 80% less energy than the majority of our existing buildings.
Whether you are motivated by concerns over global warming, worries about the increasing costs of gas and electricity or just want a comfortable environment with excellent air quality, a Passivhaus approach may provide the solution.
How is a Passivhaus different from a conventional building?
The heat exchanger uses the heat contained within the air being extracted to pre-warm the cooler external air coming in without actually mixing/cross contaminating the air.
