A purpose-built building for the RNZAF Maintenance Support Squadron at Ohakea has received this country’s first 5 Green Star – Industrial Built rating from the New Zealand Green Building Council (NZGBC).

The award for the building’s construction complements an award presented earlier for the building’s design in 2011 with the 5 Green Star rating recognising excellence in sustainable design.

NZ Defence Force chief operating officer Will Peet said the project design and construction teams had worked hard to ensure the building met NZGBC criteria and provided “fit for purpose” working space that would serve the air force’s needs well into the next century.

NZGBC chief executive Alex Cutler said the building was an example of the latest in workplace development. “Green Star certification is a clear demonstration of the Defence Force’s commitment to providing a great place to work for their personnel, as Green Star-rated buildings have proven to be healthier and more productive.

hows their commitment to energy efficiency through design and construction of a building purpose built to achieve it,” Mr Cutler said.

The building houses workshops, maintenance areas and training facilities to service the new NH90 and A109 helicopters, and to play its part in the wider Defence Force logistics chain.

It is a collection of large workshop areas for the maintenance of components and complete aircraft or other vehicles, specialist rooms for particular maintenance requirements and office areas.

Sustainable features include efficient heating, ventilation, air-conditioning systems and energy-efficient lighting; cold water systems that reduce water consumption; and sustainable use of rain and wastewater. Sound-absorbing natural materials address noise levels.

Our investigation revealed HVAC plant control and staff practices to be the cause.

Replacement of the HVAC system was uneconomic and the goals of the project needed to be completed with no impact on day-to-day court operation. As a result, a 3 stage project was launched to optimise the existing HVAC system and ensure efficient use and operation of plant.

Following completion of the project, electricity use in the building has nearly halved, and the project investment payback period was just 9 months. The success of this project displays how powerful the process of recommissioning of older buildings can be, and the ongoing savings and benefits that can be gained with only a small capital investment.

Efficiencies like those achieved at the Hamilton District Court really do represent low hanging fruit and can easily be replicated at sites across NZ.

Judges’ Comments:
“This project combined minimal capital outlay with great payback and did not disrupt normal operation. An excellent example of re-commissioning the energy management of existing building services.”
