32 Project 1 • • • • • • 2 • Water efficiency is achieved through low flow sanitaryware, as well as a drip irrigation system that reduces water consumption by more than 90%. Low volatile organic compounds used in urinals, thus negating the two largest water demands. Located within the heart of the CBD, building occupants have excellent proximity to local amenities as well as world-class public transport systems. No on-site parking has been provided; building occupants are encouraged to use the public mass transport infrastructure and/or cycle to work. Secure bicycle storage and showers are provided on site to encourage alternative forms of transport to work. The location within the CBD promotes the reuse of structures and reduces the need for urban sprawl. Although ecological improvement within the built-up environment was hard to achieve, a rooftop garden and entertainment area provide a welcome relief for building occupants. Sustainable material selection was carefully considered, together with the reuse of materials from the deconstruction phase of the project. System description All sanitaryware installed within the building has been chosen to reduce water wastage. These include: – – Dual flush toilets (3.6ℓ/min average flush) – – Waterless urinals (0ℓ/min) – – Water-efficient shower (9ℓ/min) – – Low flow taps (6ℓ/min) 1. 2. 3. Inside the new WWF-SA building.
