If you own a non-domestic building in Colchester or if one is going through planning permission and about to be built, then you should be aware that Non-Domestic Energy Performance Certificates and Recommendation Reports are required whenever a commercial building is sold, let or constructed*. This is to let any potential occupiers of the building know how energy efficient the Colchester property is and how the rating could be improved.

Buildings located in Colchester or anywhere else is in England can be categorised under 3 different levels of Non-Domestic Energy Performance Certificates. The levels represent different levels of complexity of the building and its fixed services, ranging from level 3 for simple buildings to level 5 for the most complex.

In general:

Level 3 EPC = Small existing buildings with heating systems less than 100 KW and cooling systems less than 12 KW.

Level 4 EPC = Any newly built buildings and large existing buildings with heating systems greater than 100 KW and cooling systems greater than 12 KW. A level 4 is also required if any specialised fixed services such as VAV, fan coils or chilled ceilings are used.

Level 5 EPC = These are for the most complex buildings that could have features such as ventilation with enhanced thermal coupling to the structure, automatic blind and vent controls, and atria. Level 5 buildings must be assessed using an approved Dynamic Simulation Modelling (DSM) software.

Located on the Essex and Suffolk border, close to Colchester, all our staff here at Ecodraw are fully qualified Level 5 Low Carbon Consultants and Low Carbon Energy Assessors accredited with CIBSE (Chartered Institute of Building Services Engineers). This allows us to produce Energy Performance Certificates for any level of building complexity.

We use the approved Dynamic Simulation Modelling software EDSL TAS to produce an accurate 3D thermal model of your building, which we then input all of the services into in order to generate your EPC rating and associated recommendation report.

If you require an EPC for your Colchester property, ranging from the simple to the complex, please get in touch with us today. If you are still unsure as to whether or not you require an EPC just let us know any questions you may have and we will be more than happy to help you out.

*Some exemptions as to when an EPC is required do apply. For example any buildings that do not use energy to condition their indoor environment i.e. heating, cooling or ventilation do not require an EPC. Also some buildings such as those used for religious activities, temporary buildings or stand-alone building with an area of less than 50m2 are also exempt.
