PassivHaus Design

PassivHaus refers to a low energy construction standard developed in Germany in the 1990’s by Dr Wolfgang Feist of the PassivHaus institute, Darmstadt, Germany.

PassivHaus Design offers a standard for the construction of very low energy using buildings. A building can be certified as a PassivHaus if the following set of criteria are met. These are:-

• The building should not use any more than 15kwh/m²/year in heating
• The total use of primary energy for all uses combined (including heating, hot water, and non regulated electricity use) should not be more than 120kwh/m² /year.
• U values for each external building element/envelope should not exceed values of 15W/m² K
• The building must not leak more than 0.6 times the house volume per hour pressurised to 50Pa (N/m² ) below atmospheric pressure. This equates to approximately 1/10 the current building regulations standards.

There are currently more than 17,000 buildings across the world which have been design using PassivHaus Design details
