Non-Domestic On-Construction Calculations, Assessments and Energy Performance Certificates
All new buildings now require an Energy Performance Certificate (EPC) upon completion. However, the process is different to that used for existing buildings. Sometimes called Simplified Building Energy Model (SBEM) or Building Regulations United Kingdom Part L (BRUKL) calculations, you should be working with your accredited energy assessor throughout your project to ensure you meet the Building Control requirements.
Whatever type of property you have, we can help provide the on-construction calculations you need. Our fully accredited assessors are experienced in dealing with all types and sizes of projects including shops, offices, factories, hotels, care homes, warehouses, workshops, stores and mixed use complexes. We can arrange assessments for properties whether they are Level 4 or 5 and also arrange thermal modelling if it is required. Our team are also used to working with other professionals including project architects. Additionally, if you are still at the planning stage, we can provide the reports necessary to help you achieve the permissions you need.

Frequently Asked Questions
We all need to do our bit to improve energy efficiency and to protect the environment for future generations. If you discover non-compliance you can report the matter to the relevant authority.
The Property Energy Professional Association (PEPA) has introduced a service for anyone to report instances of non-compliance relating to the energy performance of buildings regulations. Specifically, you can report:
- Failure to obtain a valid Energy Performance Certificate (EPC) in respect of marketing a property for sale or let;
- Failure to obtain a valid Energy Performance Certificate (EPC) in respect of selling or renting a property;
- Failure of a public building to display a valid Display Energy Certificate (DEC);
- Failure to obtain an Air-Conditioning Energy Inspection (ACEI) for a building requiring one.
Using the service couldn’t be simpler. To access the on-line reporting form, click here.
It can also be an advantage to the building’s owner to have a more recent assessment. This is particularly true where energy efficiency improvements have been carried out that are not reflected in the current certificate. Where buildings are tenanted, it can also make life easier for a landlord if assessments are renewed at strategic points within the tenancy cycle.
The phrase “Potential Impact” is used in the Recommendations Report for a Non-Domestic Energy Performance Certificate (EPC) to identify the impact carrying out each recommendation would have. However, it is not clearly explained and often leads to confusion. Often clients are not clear what impact is being identified (cost, carbon emissions, energy use) or how much change they can expect.
Non-domestic assessments are all based around helping the UK meet its climate obligations. As such, they are designed to reduce carbon emissions and encourage the use of cleaner fuels. It is therefore not surprising that the impact referred to is how much each recommended measure is likely to reduce the carbon emissions of the building.
For each recommendation that is automatically generated by the approved software, the carbon impact is automatically assessed. An impact less than 0.5% is described as “Low”, 0.5% to 4% is described as “Medium” and greater than 4% as “High”. For manually amended or added recommendations, the assessor should evaluate the impact using the same scale but has to do this using a modelling process.
Energy and Cost Savings
Reducing carbon emissions is not necessarily the same as reducing energy consumption or costs. Generally, using less energy will result in lower costs and lower carbon emissions but this is not always the case.
For example, changing the fuels used could reduce carbon emissions whilst increasing costs or visa versa. Different fuels behave differently so a cheaper fuel may have a larger carbon footprint. Equally, consideration would need to be given to the technology and maintenance costs associated with using each fuel type.
As with any business decision, the full range of benefits and drawbacks of implementing each recommendation should be considered prior to implementation.
