What is PAS 2038?

Are you working on a retrofit or refurbishment of a commercial building? Then PAS 2038 is an absolute must! Read on for our guide on PAS 2038, what it is and why you need it.

In the sustainable construction industry, we like to talk about retrofits. It’s become a buzzword in the energy world because of how great of an impact it can have in reducing energy efficiency within an existing build. As the UK government works to achieve its 2050 Net-Zero emissions target, the industry has had to take a closer look at its existing buildings, ensuring that they are better insulated with low carbon heating and other energy saving measures are applied to drastically reduce the 20% of carbon emissions they account for. And that’s where PAS 2038 comes in.

What is PAS 2038?

PAS 2038 is a standard that provides a set of guidelines for those wanting to complete retrofitting energy measures on their commercial buildings. It provides information on the different roles involved in the process as well as the different standards and competencies required. 

Similarly to PAS 2035, it is expected that the government schemes will require retrofit professionals to follow PAS 2038 in order to access funding. To help you get clued up on the new approach, in this blog we will discuss the ins and outs of PAS 2038, guiding you to make sure you have access to all commercial opportunities. 

What is the purpose of PAS 2038?

The purpose of PAS 2038 is to provide building owners, occupiers, energy managers and any other stakeholders involved in the build with a standard for retrofitting energy efficiency measures in non-domestic buildings. It follows the ‘whole building’ retrofit approach which will ultimately improve the energy efficiency of our existing builds, working towards the UK’s commitment of reducing carbon emissions. When the PAS 2038 retrofit is completed, It will:

What’s the difference between PAS 2035 and PAS 2038?

Of course, the benefits of PAS 2035 and PAS 2038 are vast for organisations that provide services around the enhancement of existing building stock. But, what is the difference between the two? 

Whilst both standards cover the assessment and design of energy efficiency measures, PAS 2035 covers domestic buildings, whilst PAS 2038 for commercial buildings such as student housing, hotels, warehouses and offices. That’s the only difference! Both have retrofit standards for energy efficient funding allocation, providing complete specifications for the energy retrofit of the specific build.

What buildings does PAS 2038 apply to?

PAS 2038 applies to all non-domestic retrofit activity and can be used in projects that are initiated, procured, funded and delivered by government schemes. Although, it’s important to note that not every non-domestic building will and can follow PAS 2038. If you have a non-domestic build that is domestic in size, less than 500 metres, you can opt to follow PAS 2038 so make sure to weigh up the pros and cons so  you do what’s best for your build.

What is the non-domestic retrofit process?

Similar to the PAS 2035 Retrofit Coordinator, the lead professional will act as the project manager, helping to manage the project throughout, reviewing objectives and desired outcomes. The main stages of the process include:

  1. Appointment of a project team
  2. Assessment of the building which includes context, condition, occupancy and performance
  3. Identifying and evaluating improvement options 
  4. Agreement of intended outcomes
  5. Preparation of improvement plan
  6. Carrying out retrofit work
  7. Testing, commissioning and handover of the retrofitted building
  8. Fine tuning of performance to meet targets
  9. Evaluation of the project to confirm outcomes and any unintended consequences

We know this can seem quite daunting, but thankfully, the standard includes detailed instructions on each of the areas so that your organisation can ensure that the projects are managed effectively so you can achieve your desired outcomes!
