Te Kōngahu

Powell Fenwick completed the mechanical, electric and hydraulic design for Te Kōngahu, Museum of Waitangi.

The mechanical systems design involved temperature and humidity control of the museum and gallery spaces used to house exhibits and artefacts. This included central treatment of the fresh air, which was typically high in humidity given the location of the site, through to the use of chilled and heated water air handling systems. Supplementary humidity control systems were included to account for the loads seen from occupants that can vary significantly depending on the season.  Close coordination with the architect was required to ensure adequate air tightness of the building to reduce infiltration of outdoor air and regulate the internal environment. This is closely monitored by a centralised control system that also provides historic trend information for validation to outside exhibit lenders.
