Passivhaus is the World's leading comfort and energy standard for buildings. It sets a target for the amount of heat and electrical energy that a building can use and provides a process to ensure that target is achieved. Certify your building to Passivhaus.

What is Passivhaus
The leading comfort and energy efficiency standard for buildings. It ensures comfort and low fuel bills.
Passivhaus Certification provides independent quality and technical checks throughout design and construction.
Contributing to better buildings, proven to work through feedback and monitoring.
Holistic building design
Building performance based on evaluation of the whole building using proven PHPP software. Considers how fabric and systems interact and enables design using a predicted building performance.
Improved comfort and health
Fresh filtered air to every room removes internal pollutants, dust, and cuts out pollen and pollution from outside. Consistent warm rooms in winter with minimum heating. No cold drafts when you don't want them, and no cold windows running with condensation. Warm in winter, cool in summer.
Reduce fuel poverty
Minimise the amount of energy needed to run a building to reduce fuel poverty in a meaningful, robust way. Heating bills less than £100 a year with no loss of comfort leaves cash for living.
Simple to use
You can use a Passive building just like any other building. Throw open the windows when it is hot or when you want a breeze, stoke up your woodburner in the winter. The only difference is that when you shut the windows to stay warm, it stays warm.
Fresh air always
When the windows are shut the ventilation system continues to provide fresh, filtered air completely silently. This removes smells and moisture quickly, whilst recovering the heat from the extracted air.
Design out overheating
Minimising overheating risk is carefully managed in the design process. There is a stringent target for Passivhaus buildings to meet, heat gains from the sun and equipment in the building are accounted for.
