When the new library/service centre and learning centre for south Christchurch is finished it will be among the most environmentally friendly buildings in Christchurch.

The request for such a building came from the local community during the Christchurch City Council’s public consultation process. And it is being realised in a design by Architecture Warren and Mahoney.

Work on the building by Mainzeal Property and Construction started in September. It is planned the new facilities — including a Council Service Centre, library, learning centre classrooms and café — will open in June next year, says project manager Ian McKenzie of the Christchurch City Council.

The finished complex will be set on the banks of the Heathcote River (on the corner of Colombo Street and Hunter Tce) and will be surrounded by a moat, with water as a central design theme. The library doors will open on to patio decks, creating islands in the moat, where in summer people will be able to sit and read.

Shade will be provided by roof overhangs on the building and trees. Rainwater collected on the roof will supply the moat, which will cool air circulating through low-level windows. Energy from the Christchurch water supply is to power heat pumps in winter, while low-energy light fittings are to be controlled by daylight sensors.

Water in the building will be heated by solar energy.

In keeping with the council’s Zero Waste strategy, the building will also use many materials with a recycled content and will be constructed according to a strictly enforced waste management plan. The building will also incorporate durable materials to minimise the use of surface finishes such as paint.

The café will be run by the owner/ operators of the Cashmere café, The Cup.
