Benchmarking the sustainable design and construction of building fitouts

The Green Star Interiors rating tool aims to assist clients and project teams to objectively rate their projects and achieve sustainability goals including environmental, health and wellbeing and social goals. It can be used to certify the fitout of any and all types of building, including retail, industrial and public buildings. 

Tonkin + Taylor Principal Environmental Scientist, Sandra O’Brien-Kelly, believes the new space has enhanced office culture and improved wellbeing and collaboration.

“There’s a great feeling and having access to plenty of natural light, areas for collaboration, and open spaces where we can work and catch-up has been fantastic for morale,” she says.”

What makes a Green Star fitout?

Green Star is a holistic tool that awards points across various key performance and environmental categories to assess a project's sustainability.

Projects must meet a number of mandatory benchmarks for a lower-carbon, higher-performing project, before using a combination of optional credits to achieve a final score. The greater the number of points, the higher the Green Star rating.

A rating of 4-6 stars can be awarded, with a 4 demonstrating best practice, 5 New Zealand excellent, and 6 stars putting a project among world leaders in green building.

 

The Green Star Interiors tool has a shared investment in making buildings green and making offices comfortable and uplifting. Its holistic assessment makes you consider the multiple facets of a fitout. It’s the best tool to prove a fitout is sustainable and a Green Star fitout is going to stand out above all other rentable spaces. Many agencies and developers are now requiring an Interiors rating for their buildings as they, and the market, see the value in having a Green Star certified office.
