A hefty 750 people celebrated the country’s best commercial buildings last night in Auckland at the annual Property Council New Zealand Rider Levett Bucknall Property Industry Awards, and three properties in particular set new standards for mixing design with sustainability.
The University of Canterbury's NZi3 Innovation Institute won an excellence award in the Resene Green Building Property Award category. Judges said the building was an exciting demonstration of how an integrated design approach with sustainability at its core can deliver an exceptional outcome.
Its environmentally sustainable features include solar shading by passive and active elements, an environmentally-focused selection of materials, phase change material to reduce cooling needs, mixed mode environmental control utilising under floor air distribution (UFAD) and under floor heating, intelligent lighting control and daylight harvesting and rainwater collection and reuse.
The judges were impressed with the extremely well integrated and complementary environmentally sustainable systems, successfully achieving good acoustic performance and natural ventilation, resulting in a building that presented a benchmark for others to follow.
Two buildings received a Merit Award in the Resene Green Building Property Award: the Deloitte Centre in Queen Street,Auckland and Aorangi House in Wellington.
The Deloitte Centre
The Deloitte Centre is a five-star Green Star Office building and a leader in the market with respect to the scale of the environmentally sustainable design features implemented.
The materials selected, energy and water use and waste management were given careful design attention and judges said the retention and restoration of the key features of the historic Jean Batten Building added to the achievement.
Judges said the Deloitte Centre was a great example of a premium office tower with genuine green credentials, saying it set a new standard for a commercial building in Auckland’s CBD.
Aorangi House was awarded a Merit Award in the Resene Green Building category for demonstrating how an unfashionable building from a past era could be refurbished into a desirable environmentally sustainable building with a new lease of life.
The building’s exterior was reclad and externally insulated to its full 12-storey height. Sun louvers, while providing solar shading, also allowed good daylight penetration and external views. The building uses mixed mode environmental control, mostly based on natural ventilation with a supplementary cooling system.
Judges said the building provided a very good direction for the Wellington market, showing how a building can be refurbished to become a good quality green building, without resorting to full HVAC (heating, ventilating and air-conditioning) solutions.
Submissions for the awards are open to both members and non-members of Property Council New Zealand. Entries go through a rigorous, 12-week process in which ten judges review each submission, setting it against detailed criteria. Judging also involves site visits.
Submissions needed to show economic and financial data and were judged on the return on investment, operation and maintenance factors, the degree of difficulty, environmentally sustainable features and urban design principles.
