harvested water used 2 2
All WCs are dual flush with maximum flush rates of under 4.5L
(half flush) and 9L (full flush) 1

Waterless urinals are used or only grey/rain harvested water water
is used for flushing 1 1
WA3 Wash Hand Basins
All taps have a maximum flow rate of less than 6L/minute 1 1
WA4 Showers
All showers have a maximum flow rate of less than 10L/minute 1 1
WA5 Irrigation
Landscaping does not require irrigation or all requirements met
from grey/rain water harvested water 1 1
WA6 Greywater
Grey water from over 80% of hand basins and showers reused 2 2
WA7 Rain Water Harvesting
4.0+ L of rainwater harvesting capacity per m2 of useable area 6 6
3.0-3.9 L of rainwater harvesting capacity per m2 of useable area 5
2-2.9L of rainwater harvesting capacity per m2 of useable area 4

11. Loss of biocapacity
โข Biocapacity: The capacity of ecosystems to produce
useful biological materials and to absorb waste
materials generated by humans, using current
management schemes and extraction technologies.
Global Footprint Network
13. Sustainable Building Assessment Tool:
Future Considerations
Increased emphasis on Biocapacity
โข Promoting the use of grown materials
โข Supporting the integration of ecosystems into development in order to
support local ecosystem services as well as the provision of food, health
and livelihoods
โข Drawing on local indigenous knowledge
โข Ensuring that local communities are involved in development and benefit
from this
Linked measures and positive feedback loops
โข Demonstrate how addressing biocapacity can lead to improved social and
economic benefits
โข Indicate how positive feedback loops could work: increasing biocapacity
leads to social and economic benefits, leads to reduced environmental
impacts, leads to improved biocapacity..
