minimum energy standards based on SAP 2005 calculation and % improvement on 2006 building regulations part LA
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 ● use of sun-shading devices mixed development, circus street, brighton by LCE Architects
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
