BRANZ. Welcome to BRANZ



  Providing feedback, information and data

Introduction to the section

BRANZ welcomes provision of information and data to add to and improve the current resources in the framework. By providing data and information, you consent to BRANZ having the option of making the data publically available.

Please email Dave Dowdell with data or information that you would like to submit for consideration for framework inclusion or to provide notification of data (in the case of large files).

Information we are seeking is as follows:

  • Data on building products used in New Zealand.
  • Reference buildings.
  • Information for datasheets.
  • Feedback on LCAQuick - Office.

Data on building products used in New Zealand

  • Notification of published EPDs (preferably, compliant with the EN 15804 standard) for building products used in New Zealand.
  • Critically reviewed LCIs for building products used in New Zealand. These can be provided in Excel or (if modelled using GaBi) as a ".gbx" file. Alternatively, a reference to the publically available dataset can be provided. A critical review statement or critical review report from an independent critical reviewer will also need to be submitted which confirms the findings and scope of the critical review.

Reference buildings

BRANZ would like to develop more reference buildings in order to build up a bigger library of office and other buildings for use in design in the future. To achieve this, BRANZ is seeking recently designed and consented buildings. The identity of submitted reference buildings will be treated as confidential unless otherwise notified.

Reference building information can be provided to BRANZ (with client consent) for offices and other building types e.g. schools, public buildings.

The types of information that BRANZ needs is:

  • Completed preliminary design LCAQuick - Office model (if used).
  • Consent documentation, including specification and drawings.
  • Energy modelling report.
  • Contact name and details for the architect, structural engineer and energy modeller.
  • Confirmation from the client that BRANZ may use the building as a reference.

If you would like to submit details of a recently completed reference office or other building to BRANZ, please notify Dave Dowdell by email.

Information for datasheets

Data for inclusion in datasheets to add to or replace existing data. For example, this may include information about construction site waste generation rates by product and end of life routes (for waste at the construction site and at building end of life). Data should be supported with information about the underlying study used to obtain the data and source.
