As of the UK Government’s 2015 commission of the
Each Home Counts (EHC)
review outlined 27 recommendations, which included the establishment of a universally-recognised quality mark in the form of
TrustMark
. The EHC review called for an industry-wide Code of Practice – resulting in the publication of the PAS 2035 document.
PAS 2035 is an end-to-end framework for the application of energy retrofit measures to existing buildings in the UK, alongside providing the best practices for implementation.
With there being 27 million domestic buildings in the UK, the vast amount of them require significant energy efficiency improvements. In the past, there have been efforts to deliver retrofit measures, however, as no universal standards or approaches had been agreed upon, this compounded the issue.
What does PAS 2035 cover?
The PAS 2035 specification was put into place as an approach to installing energy-efficient measures (EEMs), taking into account the standard requirements of the entire building from both a technical standpoint and considering factors such as occupancy comfort. By retrofitting buildings instead of demolishing and rebuilding, we are reducing the impact on the environment and improving the energy performance certificate (EPC) rating at the same time.
Is PAS 2035 mandatory?
From 30th June 2021 PAS 2035 became mandatory for domestic retrofit companies planning EEMs. This means that the PAS 2035 specification MUST be followed for all retrofit projects.
What is PAS 2035 retrofit?
Retrofit is the installation of additional measures to a building that were not included in its initial design. The majority of the UK’s housing does not meet the levels of energy efficiency and sustainability which is required to meet the UK’s target of Net Zero emissions by 2050. PAS 2035 was sponsored by the Department for Business, Energy and Industrial Strategy (BEIS), and designed by the British Standards Institution (BSI).
What are the roles within PAS 2035?
There are a number of professional roles outlined in PAS 2035, of which are listed below. It is not a requirement for all the roles to be carried out by separate individuals, as long as the individual who carries out each role has received the levels of training as well as certification which are required by PAS 2035. Making sure that there are no unresolved conflicts of interest.
- Retrofit Advisor
- Retrofit Assessor
- Retrofit Coordinator
- Retrofit Designer
- Retrofit Evaluator
- Retrofit Installer
Retrofit Advisor Explained
Someone to provide valuable advice to a client or householder throughout the retrofit process, the evaluation of improvement options, the selection of improvement measures (EEM), the retrofit design, the operation and maintenance of installed measures, or how to operate a home in an energy-efficient way upon retrofit completion.
Retrofit Assessor Explained
The role of the Retrofit Assessor is to gather information about the building that is subject to the retrofit works. Domestic retrofit assessments are quite broad, including factors like the building’s construction, structure, and architectural features. As well as the assessment considering the building’s current condition, including any structural defects, such as leaks, condensation, and mould build-up.
Retrofit Coordinator Explained
This role is required for all domestic retrofit projects in order for them to comply with PAS 2035. The Retrofit Coordinator holds a vital project management role within the overall retrofit process. They are needed for the protection of the client and the public. Overseeing a domestic retrofit project from inception to completion, they will liaise with building owners and retrofit stakeholders to ensure effective project management. They will be able to prepare a Medium-Team Improvement Plan using existing data from retrofit assessments, in order to provide a scope for improvements over a 20-30 year period.
Retrofit Designer Explained
A package of information will be prepared by the Retrofit Designer which will determine the unique combination of EEM systems, products, materials and their interrelationships, to be installed in a building in order to achieve specified energy efficiency.
Retrofit Evaluator Explained
The person which is qualified to monitor and evaluate the effectiveness of a retrofit project as well as provide feedback to the client and the project team.
Retrofit Installer Explained
The person or organisation which undertakes the physical placement of EEM(s) in an existing building.
