Utilizing district energy system as a cost-effective measure in meeting UK domestic 'zero carbon' targets

摘要

In 2007, the UK government announced that all new homes are to be 'zero carbon' by 2016. At present, zero carbon dwellings are significantly expensive to achieve, costing up to 40% more in capital costs than conventional building. Delivering the energy through a district energy supply achieves zero carbon at considerably less cost. This paper concluded that district energy using a large wind turbine and community biomass boiler could reduce technological capital costs by £20 000 (70%) per 128 m dwelling. It was estimated that a district energy can save £35 000 in capital and running costs over a 30 year life cycle.
