energy – domestic greenhouse gas emissions
Space heating 53%
Water heating 20%
Lighting 6%
Appliances 16%
Cooking 5%
emissions from the domestic housing sector represent about 30% of the total
minimum energy standards

energy – design considerations
● orientation
● volume / surface ratio
● use of thermal mass
● insulation
● natural light
● natural ventilation
● choice of heat supply
● use of renewables

minimum water standards
based on consumption of internal potable
water in litres / person / day using the code
water calculator
● levels 1 & 2 – above proposed water
regulations level (120 litres per person per
day)
● levels 3 & 4 – cost effective water saving
fittings (105 litres per person per day)
● levels 5 & 6 – water recycling / rainwater
collection (80 litres per person per day)
credits available – water
key design considerations:
- selection of fittings
- rainwater harvesting
- grey water recycling
minimum surface water run-off
standards
surface water management
● ensure that peak run-off rates and annual
volumes of run-off will be no greater than
the previous conditions for the development
site
● requirement for all levels
credits available – surface water
key design considerations:
- surface water management
- porous paving
- green roofs
minimum materials standards
environmental impact of materials
● at least 3 of the following 5 key elements to
achieve at least a D rating in the 2007 green
guide
-
roof
-
external floors
-
upper and ground floors
-
internal walls
-
window
● requirement for all levels
