Discover the benefits of PAS 2035/2030 and BS 40101. The UK’s Climate Change Act, as amended in 2019, sets out the statutory objective of achieving net-zero greenhouse gas emissions by 2050. This will require the reduction of all greenhouse gas emissions associated with energy use in buildings to the lowest possible level, in the context of a net zero balance between energy supply and demand.

Retrofitting is the act of fitting new systems designed for high energy efficiency and low energy consumption to buildings previously built without them.

The act of retrofitting buildings aligns construction businesses with the UN Sustainable Development Goals, contributing to Goal 3 on good health and well-being, Goal 7 on affordable and clean energy, Goal 9 on industry, innovation and infrastructure, Goal 12 on responsible consumption and production, and Goal 13 on climate action.  

To help your business get to grips with the tools we have to support with retrofit work, we have launched our Retrofit Framework Infographic.

Key Retrofit Standards

Our Retrofit Framework Infographic highlights the key standards that offer best practice guidance when it comes to conducting energy retrofits of existing buildings.

These standards include:

PAS 2035/2030 Retrofitting dwellings for improved energy efficiency. Specification and guidance.

Sponsored by the UK Government’s Department for Business, Energy, and Industrial Strategy (BEIS), PAS 2035/2030 on retrofitting dwellings is a key document in a framework of new and existing standards on how to conduct effective energy retrofits of existing buildings.

PAS 2035/2030 on retrofitting dwellings can be adopted by all those engaged in the management, design, and installation of energy efficiency measures in existing buildings.

BS 40101:2022 Building performance evaluation

They say if you can measure it, you can manage it. This is why it’s so important to evaluate the performance of buildings in a systematic and standardized way.

BS 40101:2022 is a newly published standard that provides guidance on the approaches used to evaluate actual building performance, the identification of performance parameters that warrant attention in specific circumstances, and the expertise required of individuals undertaking different degrees of building performance evaluation.

The endgame is that evaluations generate information that can help close the performance gap between the intended and actual performance of buildings.

This standard can help stakeholders to:

• Make quicker progress towards net-zero

• Reduce waste and running costs

• Improve the health and well-being of building occupants

• Drive improvements in how building fabric and structure perform long-term

• Improve the efficiency and expertise of individuals engaged in building performance evaluation

BS 40102 Health and well-being and indoor environmental quality in buildings

The BS 40102 series of standards are currently in development, to be published in 2022. The objective of this standard series is to define robust and appropriate technical standards for thermal comfort and internal air quality, for adoption in whole building retrofit projects, in order to ensure improved health and wellbeing of residents, occupants, and visitors.

The standard will establish a framework for the assessment of buildings to identify where issues occur and to set requirements for monitoring and evaluation of health and wellbeing parameters. In recent years, regulatory and commercial pressures have led designers, constructors, building owners/landlords, tenants, and maintenance teams to focus on reducing operational energy costs.

It will be split into two parts.

Part 1: Health and Wellbeing in Buildings will give recommendations for the measuring, monitoring, and reporting of the well-being and IEQ (indoor environmental quality) performance of an occupied building and the associated building services. It will provide an evaluation and rating system, the aim of which is to enhance IEQ, create healthier buildings and improve the well-being of building occupants.

Part 2: Thermal Comfort, Indoor Air Quality and Overheating will expand on issues raised by Part 1, to develop a best practice approach to thermal comfort, overheating, and internal air quality.

BS 40104 Assessment of dwellings for retrofit

BS 40104, whose publication is anticipated for 2023, will aim to provide standardization of the method of retrofit assessment described in PAS 2035/2030. This assessment is completed as part of the process that records vital evidence to the stakeholders in the process. The standard will provide requirements for the level of expertise needed for the role.

Our range of retrofitting standards and documents are available for simple and flexible access with a BSI Knowledge subscription. The flexibility and visibility it provides of the best practice guidance enables you and your team to get the most from standards before, during, and after your retrofitting activities.
