    PAS 2035 is the latest publicly available specification for low-energy domestic retrofit from the British Standards Institution (BSI). It provides specification for the energy retrofit of domestic buildings and details best practice guidance for domestic retrofit projects.

    It covers such work as:

    • Retrofit programmes promoted and/or funded by national or local government schemes e.g. the Energy Company Obligation (ECO)
    • Retrofit programmes initiated and/or funded by landlords, including social housing organizations, private landlords in the domestic sector and commercial property portfolio holders
    • Retrofit of individual buildings by their owners and/or occupants, including both domestic and commercial owner-occupiers
    • Retrofit that is integrated with and forms part of broader repairs, maintenance and improvement (RMI) activity related to individual buildings or building stocks

     

    Under PAS 2035, existing ventilation shall be assessed as inadequate for the improved dwelling if one or more of the following are apparent:

    • There is evidence of condensation and/or mould growth in the dwelling
    • There is no ventilation system, or the ventilation system is incomplete or not functional
    • There are not undercuts of at least 600mm2 beneath all internal doors, above the floor finish, to allow air to move through the dwelling
    • There is no provision for purge ventilation of each habitable room (e.g. by opening windows).

     

    PAS 2035 is there to help mitigate these risks and ensure healthy living environments for years to come.
