Research & reports

To help improve the quality of our homes and buildings we consider input from the sector and publish independent research. We are driven to improve our understanding of the impact of construction on our environment and how we can help you design and build the best buildings for our people and the planet.

Performance Leasing Guide and Model Clauses 
This Guide enables tenants and landlords to create better performing, more energy efficient buildings. A joint initiative between government and industry, it was developed by EECA, lawyers DLA Piper New Zealand, and NZGBC.

The model clauses are designed to insert directly into lease agreements, and cover issues of:

  • co-operation between tenants and landlords
  • energy use, water and waste
  • quality of the indoor environment
  • use of rating tools such as Green Star and NABERSNZ.

The Guide was adapted from a resource produced by Sydney’s Better Buildings Partnership (BBP), a government/ industry initiative.
