What is Passive House?

Passive House is a voluntary standard for energy efficiency in a building, which reduces the building’s ecological footprint. It results in ultra-low energy buildings that require little energy for space heating or cooling. The standard is not confined to residential properties; several office buildingsschoolskindergartens have also been constructed to the standard. The design is not an attachment or supplement to architectural design, but a design process that integrates with architectural design. Although it is generally applied to new buildings, it has also been used for refurbishments.

What are the benefits?

If a building is designed to Passive House standards, the living environment is carefully controlled to give the occupants excellent air quality whilst cutting their energy usage dramatically. 

Low-energy, or Passive House buildings, have a higher value to buyers and tenants. For portfolio landlords, they retain their value with lower maintenance costs, tenants stay for longer, and vacant periods tend to be shorter than in traditional buildings.

I educational buildings, the working environment is optimised, and savings are made when the buildings are not being used.

Of course, the lower energy demands of Passive House buildings have a much lower impact on the environment.

Is Passive House more expensive?

In Passive House buildings, the cost savings from dispensing with the conventional heating system can be used to fund the upgrade of the building envelope and the heat recovery ventilation system. With careful design and increasing competition in the supply of the specifically designed Passive House building products, it is increasingly possible to construct buildings for almost the same cost as those built to current building standards. On average passive houses are reported to be more expensive upfront than conventional buildings – 8% to 10% in UK.
