Te Hononga

Powell Fenwick provided all of the engineering services for this project including Structural, Mechanical, Electrical, Fire, Civil, Hydraulic, Acoustic and Green Star.

Powell Fenwick worked closely with Ngai Tahu and Christchurch City Council (CCC) on this very successful project for the new CCC offices.

Key features of the project included 6 Green Star Office Design, As-Built and Interiors ratings. Te Hononga is New Zealand’s highest rated Green Star Building, receiving 6 Stars signifying ‘World Leadership’.

It included an innovative use of Council landfill gas from Burwood to power Trigen plant for building base electrical, heating and cooling loads to reduce environmental impact (approx. 90% reduction in carbon emissions compared to a traditional design) and operating costs (approx. three year payback for Trigen/Landfill gas system).

Other innovations included the integration of the CCC owned Civic Trigen system with the CCC Art Gallery building with a complex electrical changeover system to power the Art Gallery from the Civic Trigen when excess capacity is available.
