8R.1.4 Examples of ESD Measures
Water Efficiency
These measures ensure all non-residential buildings implement systems
of water collection and recycling. Systems to minimise mains water usage
may include:
i) On-site rainwater collection and on-site waste water treatment to
provide recycled water for use within the development.
ii) Provide low flush toilets and water efficient fixtures and fittings,
including waterless urinals.
iii) Utilise water efficient landscape principles, such as the selection
of low water usage species, including local species, and the use
of tree foliage to create on ground shade and windbreaks.
Energy Generation
These measures encourage implementation of systems that provide
alternative energy sources. Energy generation measures may include:
Wind turbines
The exhaust plenum is at slightly
negative pressure, induced by north
flues stack effect and wind-powered
turbines
Vertical planting
Green north facades and roof top
assists shading, glare and air quality.
Access to nature enhances
productivity relieving stress.
Shading and light
Light shelf and balcony floors provide
horizontal shading from northern sun.
Ambient and direct daylight bounces
off external and internal light shelf.
i) Solar louvres (powered by photovoltaic cells) that track the sun to
supply building use;
ii) Solar hot water system;
iii) Solar energy collection technology such as solar heat pumps for
hot water and photovoltaic cells;

Healthy air
100% outside air supply via vertical
ducts deliver air floor by floor to
sealed access floor plenum.
Displacement air
Fresh air fed at low speed
through controllable floor vents.

Chilled ceilings
Chilled ceilings panels absorb radiated
heat from equipment and occupants.
Occupants experience ‘coolth’ by
radiating heat to chilled ceiling overhead.

Thermal mass
Thermal mass in concrete

Shower towers
Air and water falls to provide
cool water for building
reticulation and cool air to
supplement ground floor and
retail cooling.
