Tohora House Whangarei’s first Greenstar Building

Tohorā House has become the first building in Whangarei to achieve a Green Star rating for its sustainable and energy-efficient building design.

Tohorā House has achieved a 4 Green Star Design rating – denoting best practice – from the New Zealand Green Building Council (NZGBC).

The NZGBC noted smart design decisions from the outset helped Neil Wild & Associates build environmental efficiency into the building and create a comfortable, energy-efficient indoor environment.

Tohorā House is made of lined precast concrete, which has high thermal stability, keeping the interior cool in summer and warm in winter. Extended overhangs provide shading at the hottest time of the year, helped by heat-reflective glass coatings. Tohorā House’s lights are highly efficient LEDs, and are controlled separately around the building’s perimeter to reduce the use of artificial light and energy during the day.

Opened in April 2015, Tohorā House also features an energy-efficient air conditioning system, with the ability to recover heat from the hot-water system.

Northland DHB chief executive Dr Nick Chamberlain says it was important to invest in a building that prioritises sustainability and efficiency.

“Tohorā House exemplifies the benefits of well-planned new construction, bringing together formerly separate teams, providing the opportunity to operate as a ‘whole of system’ organisation, and saving costs. Green Star helped us verify that our new building is energy efficient, providing a much better working environment for our staff and while helping to save the planet.”
