CO₂RE


Provides calculated carbon footprints per square metre for residential roof, wall and floor constructions.

CO₂RE draws on residential construction elements from the BRANZ House Insulation Guide (5th edition) and a few details from the PHINZ High Performance Construction Details Handbook https://passivehouse.nz/hpcd-handbook . It enables the user to:

  • Find out the estimated climate change impact for different types of residential roof, wall and floor constructions.
  • Compare the carbon performance of alternative roof, wall and floor constructions according to a desired minimum construction R-value.
