Capital building best of its kind in New Zealand

20 December 2017

A Wellington waterfront building is the first in New Zealand to receive the highest possible energy efficiency rating.

33 Customhouse Quay, which reaches four storeys high, has over 300 workers and boasts floor area in excess of 5,000 m2, is the first building to be awarded the top 6 star rating under an independent, government backed energy efficiency scheme called NABERSNZ.

NABERSNZ, which is run by the nation’s leading sustainable building organisation, the New Zealand Green Building Council, assesses the amount and type of energy used, measured against the size of the building, and has ratings from 0 stars, which indicates poor performance, to six stars, which shows aspirational performance.

33 Customhouse Quay is owned by Stride Property. In November, Stride were one of over 20 organisations who made a landmark commitment to tackle energy efficiency and called for the Government to do more to encourage all businesses to do the same.

Sam Archer, technical director of the New Zealand Green Building Council, said: “This six star rating is brilliant. Well done to Stride, who are showing world class with this great green building.

“It’s not just environmental benefits that energy efficiency brings. There’s good evidence that energy efficient buildings also provide a better indoor environment for staff and that leads to productivity gains. That’s why there’s a real shift towards better, healthier, green buildings in New Zealand.”

Alan Barbour of Beca, who led the environmental design of the building said: “33 Customhouse Quay was designed and constructed to be a leading edge building, and to set new benchmarks for sustainability and efficiency.

“The 6 star NABERSNZ rating is a terrific achievement, and confirms the value added by the combination of the low energy design inclusions and the continued commitment of the owner Stride Property and their tenant.”

Commercial buildings use over 20 percent of New Zealand’s electricity, costing businesses $800 million every year.

NABERSNZ is a Kiwi adaptation of the National Australian Built Environment Rating System. A NABERS assessment is mandatory for large buildings in Australia, but not yet in New Zealand.

33 Customhouse Quay was also the first in New Zealand to be awarded a Green Star rating, receiving 5 Stars in October 2007 showing that green designed buildings are also green in operation.
