Green Star & NABERS

TMCO helps buildings across Australia and New Zealand achieve Green Star and NABERS ratings with practical, cost-effective strategies that improve performance, support compliance, and demonstrate sustainability.

Sustainability advice that improves buildings and cuts carbon.

Ratings like Green Star and NABERS are a means to a better building, not an end in themselves. We give practical, cost-effective advice that improves performance, supports compliance and demonstrates sustainability.

Building modelling and simulation

Thermal modelling for integrated design of services and thermal envelope. Using both dynamic and static modelling software, we offer design analysis across residential, commercial and industrial applications:

  • Overheating risk analysis
  • Solar PV performance design
  • CFD and energy efficiency analysis
  • HVAC loads analysis
  • Green Star greenhouse gas modelling
  • NatHERS thermal comfort modelling
  • NCC Section J compliance modelling
  • Wind modelling at macro and micro scale

Ratings and certification

We guide projects through Green Star, NABERS and other rating tools, and translate the requirements into practical design decisions. This might include:

  • Green Star design and as-built ratings
  • NABERS energy and water ratings
  • Carbon and lifecycle assessment
  • Pathways to net zero and lower embodied carbon

For new buildings

Sustainability decisions made early, from orientation and thermal envelope to services and controls, set the performance of the whole building. Early input delivers a better rating for less cost.

Options that are costed and clear

We set out the sustainability options with their pros and cons, capital and running costs, available funding and payback comparisons, so you can make an informed decision with no nasty surprises.

Modelled within the design

We model performance within the architect's actual model, using Revit and ArchiCAD, so sustainability is designed in, not bolted on.

A track record of firsts in sustainable buildings.

Our team members designed one of the highest Green Star rated (6 star) buildings around, the Christchurch City Council Civic Building.

We have many firsts, including New Zealand's first NABERS whole-building rating, its highest NABERS rating, its first certified carbon-zero building and the first Green Star church, many of which have won awards.

When will you benefit by involving us?

At the outset of a new project

Sustainability set as a goal at concept stage is far cheaper to achieve than one added later. Early input shapes orientation, envelope and services for the whole project.

  • When you are targeting a Green Star or NABERS rating
  • When you want lower energy and carbon with a clear payback
  • When an existing building needs a performance review
  • Whenever running cost and sustainability matter
