Whole-building whole-of-life framework


The New Zealand whole-building whole-of-life framework provides tools, data and information to support decision making for sustainable building design. It assists calculation of the climate change impacts and other environmental impacts of our buildings.

Calculating environmental impact

We cannot put a meter on a building to measure its environmental impacts. This can only be achieved through calculation using techniques such as carbon footprinting or life cycle assessment (LCA). For complex, long-lived products such as buildings, this calculation requires a lot of data, scenarios and assumptions.

The framework supports these calculations through the tool LCAQuick and the carbon footprint data provided by BRANZ CO₂NSTRUCT.

LCAQuick: Life cycle assessment tool

Use LCAQuick to calculate the greenhouse gas emissions (and other environmental impacts) associated with building designs and to iteratively reduce or design out carbon (and other environmental impacts).

BRANZ CO₂NSTRUCT: Embodied carbon and energy datasheet

BRANZ CO₂NSTRUCT contains embodied greenhouse gas and energy data for construction materials and products. The data in BRANZ CO₂NSTRUCT is derived from several sources, and provided in the database with a data quality metric.

About the framework

The pages below provide more information about:

  • how and why the New Zealand whole-building whole-of-life framework was developed
  • reference buildings to compare building plans
  • building carbon footprints and LCAs
  • environmental indicators calculated by the framework.

Framework applications

These applications can be used by architects, designers and engineers to help make sustainable design decisions early in the construction process.
