Beca's revolutionary artesian heating and cooling system for Christchurch International Airport has attracted international industry recognition, winning International Project of the Year at the 2015 CIBSE Building Performance Awards.
The CIBSE Building Performance Awards recognise engineering excellence in the built environment, with an emphasis on energy efficiency. Winners are acknowledged as 'best in class'.
Celebrations kicked off at the awards dinner on 10 February at the Grosvenor House Hotel in London, as the 14 category winners were announced, along with the recipient of the coveted Carbon Champion of the Year Award.
Watch Justin Hill, Beca Christchurch Building Services Manager, accept the award and talk about the unique artesian heating and cooling system, delivered as part of Christchurch International Airport's $237million Integrated Terminal Project. The ethos of which was sustainable, energy efficient operations.
The essence of the system is the use of artesian water that flows beneath the city of Christchurch and the Canterbury Plains. Easily accessible through wells, the artesian water provides the airport with a cost-effective, long-term heating and cooling solution, and a super-efficient, sustainable energy source when used in this manner.
Chillers, which act as geothermal heat pumps, provide both mechanical cooling and heating. And 12oC artesian water is used for direct cooling. This innovative system enables artesian water to heat or cool the building or do both, at any one time. It also has the ability to recover and redistribute heat energy around the building.
"The CIBSE Awards are unique in the industry in that they don't just examine the design of projects and products" says Hywel Davies, CIBSE Technical Director and Chair of the Judging Panel. "What sets our awards apart is that they are focused very firmly on assessing how buildings perform. This is particularly important when both energy security and generating capacity are increasingly uncertain."
The innovation also recently won the Building and Construction category at the 2014 New Zealand Engineering Excellence Awards, and a Gold Award of Excellence at the 2014 ACENZ INNOVATE New Zealand Awards.
Congratulations to our teams on this outstanding achievement, and well-done to all the 2015 CIBSE Award winners and finalists on their entries.
