Promotion of European Passive Houses (PEP)

Tags:
Big savings in home energy consumption are there for the taking. The Passivhaus concept offers a workable, affordable solution for achieving such savings. However, we need to pass on the experience we have gained beyond small groups of experts by targeting a wider community of building professionals. PEP therefore set itself the task of spreading this knowledge throughout Europe using various channels.

Results

  • Over 2 000 000 visitors to the PEP web-site in two years.
  • Guide for architects and planners with tips on dwelling design and choice of construction sites.
  • Guide for energy designers with tips on building envelopes and energy calculations.
  • Guide for structural designers with tips on comfort, thermal bridges and air tightness.
  • Passivhaus Planning Package improved: a tool allowing design to be checked against Passivhaus requirements after entry of data on material and components

Lessons learned

  • Following the definition developed by the Passivhaus Institut, a Passivhaus has a heat demand of 15 kWh/m2 floor area per year, whilst the total primary energy use in the house is restricted to 120 kWh/m2 per year. The Scandinavian partners of the project have shown that these are unrealistic criteria for their countries. In consequence, for Northern Scandinavia and other countries with cold climates, a more flexible definition of the Passivhaus concept is required.
  • With the Passivhaus technology on the brink of large market penetration, contribution to the Kyoto agreement for this period will be small. However, through the Passivhaus concept considerable energy saving compared to the business as usual can be obtained. This energy saving potential implies high CO2 reductions of 50-65 % for each building.
  • An inventory has been made of market introduction barriers and possible solutions. Most frequently encountered barriers in partner countries are: limited know-how; limited contractor skills; and limited acceptance of the Passivhaus concept in the market.
