    Abstract

    This research examines the cost effectiveness of the Passivhaus standard for social housing construction in England, and whether it is worthwhile for social housing providers to build to the standard from a life cycle cost (LCC) perspective.
    A critical review of the literature has ascertained the minimum standards for social housing construction in England and the underlying reasoning behind the choosing of Passivhaus over other alternative methodologies that are less expensive.
    The time taken to build Passivhaus continues to take longer than a traditionally built home as more attention to detail is required but according to the Homes and Communities Agency who regulate social housing in the UK, their house building targets for social housing are being met, so this is not the upmost priority for social housing providers. This is in contrast to the open market sector where house builders are falling short of their targets.
    The quality aspect of Passivhaus is also not an issue as the standard follows a rigorous certification process that is difficult to achieve, with the priority resting on airtightness levels.
    The primary research was completed using existing case studies of Exeter city council Passivhaus developments and Southern Housing Groups first Passivhaus development on the Isle of Wight, along with interviews with a selection of people from each project. The interviews highlighted the requirement for social housing Passivhaus dwellings being focused on the residents and the issues surrounding fuel poverty rather than cost. The research shows that there is an issue surrounding fuel poverty in the UK that is a priority for councils and housing associations to tackle.
    In conclusion the research has found that a combination of factors influence whether or not a Passivhaus development will be cost effective, these being; experience of the contractors, knowledge of Passivhaus by sub-contractors, the cost of certified materials, these all play a role in the cost effectiveness of a project. This is followed by the conclusion that Passivhaus costs should come down due to the pending implementation of government legislation.
