Reducing the carbon footprint of existing UK dwellings – three case studies
2012
Singh, H. | Eames, P.C.
A set of technological interventions has been identified which are suitable for applications in the majority of existing UK dwellings and which would significantly reduce their carbon footprint. The dwelling types are semi-detached, detached and terraced. The paper considers two scenarios, viz. i) using present-best technologies and ii) looking at the likely-future technologies. The research has assessed the effectiveness of the selected technological interventions. These reduce heating demands and as a result there is a decrease in carbon dioxide emissions. It is concluded that the total CO2 emitted because of space and water heating can be reduced by up to 86, 87 and 86% respectively for the semi-detached, detached and terraced dwellings using likely-future technologies and by up to 78, 77 and 82% using present-best available technologies. This assumes that the proposed mechanical ventilation system used in conjunction with a heat-wheel heat recovery system (MVHW) runs on green electricity generated by a solar PV system.
