To help you assess the thermal performance of your build and ensure it is compliant with the updated H1 energy efficiency standards, we have created a free, easy to use, online H1 calculator. This calculator will also help you optimise your design, find the most cost-effective route towards compliance, and calculate by how much your design would pass or fail compliance.
Find you H1 compliant design in 3 quick and easy steps:
- Enter your climate zone, date of building consent application and size of your building.
- Enter your proposed construction R-values for each building element.
- The calculator will compare the heat loss from your proposal with the equivalent reference building and confirm whether your design would pass or fail H1 compliance.
