It is evident that significant improvements need to be made within the energy efficiency of the UK’s building stock, if the country is to meet its global carbon commitments.
In 2015 the government commissioned the Each Home Counts review to identify and tackle the high level of failure present in domestic retrofit, and to determine a better process for the retrofit of energy efficiency and renewable energy measures. PAS 2035 (PAS 2035:2019 Specification for the energy retrofit of domestic buildings) was introduced as a result of this review, with the backing of industry and the government department for Business Energy and Industrial Strategy (BEIS). Following a transitionary period the government has proposed to make compliance with PAS 2035 mandatory for all public funded projects which would include ECO funded retrofit projects.
How is Pas 2035 different
The PAS embraces quality retrofit work eliminating problems associated with defects, shallow retrofit, accountability, poor design and performance gap. PAS 2035 delivers a whole building approach to the retrofit process, considering the home, environment, occupancy and the suitable measures to install. This eliminates the issue of the retrofit work being considered in isolation which can unintentionally damage the overall building performance.
Where is PAS 2035 applied?
PAS 2035 and the retrofit standards framework may be applied to all domestic retrofit activity and embrace work that is initiated, procured, funded and delivered in a wide variety of ways including:
– Programmes of retrofit promoted and/or funded by national or local government schemes
– Programmes of retrofit 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 form part of broader repairs, maintenance and improvement (RMI) activity related to individual buildings or building stocks.
