Commercial EPC's and Residential EPC's are slightly different. A residential EPC for a new build will use your SAP results to create the EPC. For residential new builds this is usually completed from the plans. If you have an existing residential building, this is completed with actual measurements and observations from the site.

However, commercial EPC's are slightly different. The basics are the same, the EPC will show you how energy efficient your build is, and it will also state where improvements can be made. However, a level 4 energy assessor must undertake a new build commercial EPC. Commercial new builds usually have certain targets to reach to get certification. You will need to speak to your assessor to understand your requirements.

The EPC is predominately a desk-based service. However, a site survey may need to be carried out. The commercial EPC will use the SBEM Software, while a residential EPC will use the SAP Software.

There are many aspects which will contribute to your EPC, resulting from the airtightness of your build, to any renewable technologies used.

To get the best results, you can speak to our Energy Experts at the beginning of your project to ensure that you build to the correct standards and implement your goals for compliance.

The New Build commercial EPC is a direct output from the SBEM. This basically calculates the CO2 emission rate, this is also known in the industry as BER – Building emission rate. This MUST not be greater than the Target emission rate also called the TER. Information is mainly derived from Build specification and and a full set of scaled drawings and inputted in to our SBEM software (SBEM stands for : Simplified Building energy model)

Some considerations within this certification are:

• • New Build EPC - Lighting

• • New Build EPC - U-Values

• • New Build EPC – Fabric

• • New Build EPC - Windows

• • New Build EPC - Air Tightness

• • New Build EPC - Heating and Cooling

• • New Build EPC - Renewable Technologies

• Being an Energy assessor myself, one of the best pieces of advice is to get to us at the Design stage to make sure all the build specification complies to the Part L2 regulations.  

Please pick the phone up to speak to one of our energy experts in Commercial EPC’s we will be happy to help. If you need to combine other Services for a one stop shop convenience package let us know as we are trying very hard to make compliance uncomplicated.
