energy – domestic greenhouse gas emissions
emissions from the domestic housing sector represent about 30% of the total
Space heating 53%
Water heating 20%
Lighting 6%
Appliances 16%
Cooking 5%
minimum energy standards
based on SAP 2005 calculation and % improvement on 2006 building regulations part LA
code level energy performance
equivalent rating
level 1 10% improvement EST good practice
level 2 18% improvement
level 3 25% improvement EST best practice / ecohomes- very good
level 4 44% improvement ecohomes- excellent
level 5 100% improvement
level 6 full zero carbon exemplar

energy – design considerations
● orientation
● volume / surface ratio
● use of thermal mass
● insulation
● natural light
● natural ventilation
● choice of heat supply
● use of renewables
● low energy lighting
● use of conservatory sun space
● use of materials

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
