We are currently working on the first phase of the Durand Close regeneration in Carshalton, Surrey for our client Rydon Construction. The first phase includes 112 residential units, along with a community centre.
There is a planning requirement for 12% of the sites carbon emissions to be reduced by renewable technology, with a further 11% being reduced by low carbon technology.
White Associates have provided an alternative design strategy for our client which involves the use of biomass plant as a lead boiler to provide 30% of the on-site energy demand; therefore exceeding the planning requirement for the combined requirement of renewable and LZC technology with a completely renewable source. This 30% biomass inclusion under SAP 2005 Appendix Q has proven a 25% reduction in calculated carbon emissions using NHER figures (to include cooking and small power use, whereas SAP alone only covers heating, hot water, and lighting).
This has proven to be a greener, and yet more cost effective solution to our client than the planning proposals. White Associates are always prepared to investigate, and if necessary provide alternative proposals based on our detailed SAP calculations and summary reports.
