The residential sector has been identified as one of the most prospective for significant cost-effective reductions in energy use. Multiple possible transition paths are possible towards ‘zero carbon’ emitting housing as the basis for a de-carbonisation of the housing sector. This paper focuses on the carbon footprints of alternative configurations of dwelling types, various ratings for the thermal performance of the building shell, a mix of built-in and plug-in domestic appliances, and local energy generation technologies. These scenarios which provide transitions to zero carbon housing are discussed. Known as ‘hybrid’ dwellings, they deliver significant energy, and GHG savings per year compared to new housing designed to current standards.
This paper is one of a series of papers from a single study, Hybrid Buildings: Pathways for Greenhouse Gas Mitigation in the Housing Sector by the same authors, covering the energy use within the residential sector.
