Green Star NZ - Performance

The Green Star NZ suite of rating tools was designed as a three-stage process to match the key phases in a building life cycle - Design > Built > Performance. Now that Design and Built tools are available for office, education and industrial buildings we are focusing on developing a Green Star – Performance tool.

This new tool will definitely cover Office buildings but it has not yet been determined which additional building types will be addressed by the tool.

The Performance tool is critical to driving the building and property sectors to greater levels of performance and efficiency. The tool will play a key role in ensuring the initiatives implemented during design and construction of new buildings and refurbishments, are delivering actual savings. In addition to providing essential information to close the loop on building design and performance, it is also expected this tool will be taken up by existing building owners, occupiers and managers as a benchmarking and decision-making tool.


 

Tool Development Process

In July the NZGBC held stakeholder workshops in Auckland and Wellington to seek initial input to the direction of a Green Star - Performance rating tool. The central feedback from these workshops was that the tool should be:

  • cost-effective
  • simple
  • clearly linked to the whole Green Star system
  • deal robustly with base building versus tenancy issues
  • measureable, accessible and transparent

These workshops helped identify a strong interest in and market demand for an Energy Performance Certificate to benchmark a building's operational energy performance only. We will therefore be pursuing the development of this as well as a holistic Green Star - Performance rating (which will address broader environmental sustainability concerns applicable to other Green Star tools, such as energy, water, indoor environment etc).

The feedback period on the proposed scope of the Green Star - Performance tool has now closed. Please see below for the feedback form, and the summary of feedback.

Green Star – Performance, Proposal Feedback Form

The feedback period has now closed. 

A Steering Group (see Table 1) to oversee the tool's development has now been established and a Technical Working Group will be set up in November to provide a broad range of expertise into the technical development of the tools.

Expressions of interest are currently being sought from experienced parties to be part of the Technical Working Group (if you are interested please email greenstarnz@nzgbc.org.nz).

Steering Group Membership
Organisation Representing
Property Council Building owners and developers
CoreNet Tenants
Facility Managers Association Facility managers
Electricity Commission Government's electricity efficiency policies and priorities
Energy Efficiency and Conservation Authority Government's electricity efficiency policies and priorities
Ministry of Education Education facility portfolio

Further stakeholder input will be sought in October when we release an outline proposal of for the tools. If you would like to receive notification of when the proposal is released please email greenstarnz@nzgbc.org.nz and include 'Performance Tools' in the subject line.


 

Project milestones and dates

The key milestones and dates for the tool's development are set out below. These dates are dependent on

Tool Scoping Phase (July '09 - November '09):
Stakeholder Workshops held in Auckland and Wellington July 2009
Stakeholder feedback summary produced September 2009
Steering Group first meeting held October 2009
Feedback period for outline proposal October 2009
Tool Scoping Report finalised November 2009
 
Tool Development Phase (will begin when full tool funding has been raised through industry support):
Expressions of interest called for Technical Working Group
Technical development of tool
Anticipated pilot tool release date
Feedback period for pilot tool
Final tool release

All tool development dates are highly dependent on this project achieving full sponsorship, and the availability of data. These dates will be updated as the project progresses.


 

Tool Sponsorship and Market Leadership

We are currently seeking expressions of interest from organisations seeking to adopt a market leadership position in relation to building performance.

Sponsorship packages are available for the development of the Green Star - Performance tool. To discuss these options further please contact the NZGBC Marketing and Membership Manager Kirsty Campbell on (09) 379 3996 ext. 908 or kirsty@nzgbc.org.nz.
