CO2RE live webinar


CO₂RE draws on residential construction elements from the BRANZ House Insulation Guide (5th edition) and some details from the PHINZ High Performance Construction Details 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 different roof, wall and floor constructions according to a desired minimum construction R-value.
