Powell Fenwick completed the Mechanical, Electrical, Civil and Hydraulic engineering services for the Waimakariri District Council Ruataniwha Kaiapoi Civic Centre.

The building consisted of a museum, community library, service centre and civic courtyard. The mechanical services involved solar energy modelling to allow accurate design of the solar shading. Other features include an optimised mix-mode system which allows passive cooling and ventilation working in conjunction with the under floor heating.
