Retrofit Assessment

Dwellings which require energy retrofit work will first need to be assessed by a Retrofit Assessor. 

These assessors play a critical role in the PAS 2035 process as they collect and provide property data/information which Retrofit Coordinators can use to develop a relevant improvement plan.

Reports produced by the Retrofit Assessor include:

  • Energy Performance Assessment
  • Condition Survey
  • Occupancy Assessment
  • Heritage Impact Assessment (Risk Pathway C – Traditional Buildings)

Retrofit Coordination

In order to comply with PAS 2035 every domestic retrofit project will need to be managed by an approved Retrofit Coordinator. 

A Retrofit Coordinator is the individual who will be responsible for overseeing the assessment of dwellings as well as the subsequent specification, monitoring, and evaluation of energy efficiency measures, in accordance with PAS 2035.

A Retrofit Coordinator will manage a retrofit project from inception to completion, and will need to liaise with Clients, Retrofit Assessors, Retrofit Designers and Retrofit Installers in order to ensure effective end-to-end project management and successful delivery of the project as a whole.

The activities that Retrofit Coordinators are expected to undertake as part of the PAS 2035 process include:

  • Liaison with the client to set in place the Intended Outcomes of the project
  • The completion of a retrofit risk assessment for each dwelling or dwelling type within the retrofit project
  • The development of a retrofit project plan
  • The development of a medium term improvement plan for every dwelling, for implementation over a period of thirty years
  • The documentation of the project progress, including any information that is supplied by building owners, and other retrofit stakeholders involved in the delivery of the project

Retrofit Design

The main responsibilities of the Retrofit Designer are:

  • Designing and planning energy efficiency retrofit for residential buildings
  • Analysing the impact of the specified energy efficiency measures (EEM)
  • Issuing visual and technical advice and guidance, which may include the use of 3D Building Modelling

Prior to undertaking the design and specification of retrofit work, the Retrofit Designer shall ensure that they are in possession of a retrofit assessment for the relevant dwelling or dwelling type, prepared by a Retrofit Assessor, on the basis of which the retrofit design shall be prepared.

Retrofit Evaluation

The Retrofit Evaluator shall collate the information provided by the Client and the occupant(s), summarise it, formulate recommendations for any remedial actions required and any changes to the retrofit process that may be appropriate, and circulate the summary and recommendations to the Client, the Retrofit Coordinator, the Retrofit Assessor, the Retrofit Designer and the Retrofit Installer.

Three levels of monitoring and evaluation shall be carried out, as appropriate:

  • Basic monitoring and evaluation shall be applied to every completed domestic retrofit project
  • Intermediate monitoring and evaluation shall be applied to projects for which (in the opinion of the Client, the Retrofit Coordinator or the Retrofit Evaluator) basic monitoring and evaluation indicates that the outcomes are significantly different from those originally agreed and intended, or there are unintended consequences of the retrofit work
  • Advanced monitoring and evaluation shall be applied to projects for which (in the opinion of the Client, the Retrofit Coordinator or the Retrofit Evaluator) intermediate monitoring and evaluation indicates that further investigation is required to understand and resolve any discrepancy between predicted performance and outcome performance, or to explain any unintended consequences
