NOTE re this review draft:

PAS 2030 Scope summary.

This revision of PAS 2030 specifies requirements for the installation of Energy Efficiency Measures (EEM) in existing buildings (not new build) used for both dwelling and non‑dwelling purposes and is intended for use by entities undertaking the installation of any products and/or systems designed to improve the energy efficiency of such buildings. For dwellings, that design is required to be in compliance with PAS 2035 (currently in development and also released for review). For non-dwellings, requirements for the design remain as for the 2017 edition. This revision also extends the application of the specification to include the insulation of residential park homes, through the addition of measure specific annex B13.

As with previous editions, this PAS includes requirements in respect of installation processes, process management and service provision and includes criteria relating to installation methods, equipment, tools, product or system and material suitability, the commissioning of installed measures and the training, skills and vocational qualification of the people undertaking such installation. The PAS includes information provided to assist installers to fulfil their responsibility to ensure the effective co‑functioning of EEM installed in the same building.

This PAS consists of core requirements to be met by any entity claiming compliance with it, and normative measure-specific Annexes setting out supplementary requirements for each included measure type.

Claims of compliance with this PAS will be in respect of the processes and procedures employed and their application in the installation of EEM in any given building. Such claims do not reflect the quality or performance of the retrofit design, which will be the subject of claims of compliance with PAS 2035 or, for buildings other than dwellings, other assurances or guarantees provided by the design source.

This PAS requires claims of compliance to be in respect of the core requirements and all Annexes relevant to the measure installation undertaken by the claiming entity. The entity is also required to identify whether the claim is on the basis of self‑assessment, other party assessment or independent third‑party validation and to differentiate between installation undertaken on the basis of an installer provided EEM design and that undertaken in accordance with an EEM design provided by an independent third party.

This PAS specifies requirements for retrofit of dwellings, including: assessment of dwellings for retrofit; identification and evaluation of improvement options (energy efficiency measures, or EEMs); design and specification of EEMs (whether individual measures or packages of multiple measures); and monitoring and evaluation of retrofit projects.  It covers EEMs that are intended to:

improve the insulation of the elements of the building fabric (exposed floors, walls, roofs, windows and external doors) and reduce thermal bridging;

improve the air-tightness of the building envelope;

improve the resistance of the building envelope to water penetration and its resilience against flooding;

establish a safe dynamic moisture equilibrium through each element of the building fabric,

provide or upgrade ventilation to ensure good internal air quality and minimise the risk of condensation;

minimise the risks associated with overheating;

provide efficient heating and cooling systems with responsive, intelligent or ‘smart’ controls, including systems that use low or zero carbon (LZC) technologies;

provide efficient water heating systems with responsive controls, including systems that use LZC technologies;

provide efficient fixed lighting with appropriate controls;

provide efficient appliances and equipment to reduce electricity use and minimise internal heat gains;

provide locally generated renewable electric power, e.g. by means of solar photovoltaic (PV) systems and micro combined heat and power (CHP);

provide on-site energy storage to improve the usefulness of energy generated by LZC technologies;

provide metering and monitoring systems to promote the efficient use of energy;

In addition to setting out requirements for the commissioning and handover of all of the above, this PAS also specifies requirements for advising building occupants about improvement options appropriate to their homes, and the efficient and appropriate use and maintenance of their retrofitted homes as well as for monitoring and evaluating retrofit projects when appropriate, and feeding back lessons learned to all parts of the supply chain, including the building occupants.

Many aspects of domestic retrofit are covered by existing standards.  Where appropriate those standards are referred to in this PAS, and compliance with the standards referred to is thereby a requirement of this PAS.

This PAS 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 organisations, 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;

This PAS and the retrofit standards framework may also be applied not only to retrofit work carried out by commercial building contractors and specialist installers of retrofit measures but also to work carried out by local SME builders and independent tradesmen working alone or in small teams.
