What is the Cost of Building a Passive House?

The most recent Part L of the Building regulations requires that all new buildings need to comply with NZEBs (Near Zero Energy Building) i.e. an A2 or above EPC rating.

To satisfy Passive House Certifications, your building needs to achieve an A1 EPC rating. The cost of building a Passive House that achieve such standard is generally between 10% to 15% more expensive than a conventional house. However there is a cost saving over time and the pay back is estimated to be between 7 and 10 years, such as:

  • RUNNING COSTS - Heating and hot-water costs for a Passive House should be in the region of just €0.15 per square metre, per year
  • RESALE VALUE - Energy efficiency increases the resale value of your property
  • GRANT SUPPORT - Please check out our NZEBs section for details on grant support.
