What is a Commercial EPC?

Energy Performance Certificates (EPCs) help in improving the energy efficiency of a building, and reducing carbon dioxide emissions. A commercial EPC, as the name suggests, is provided for a commercial building, by a highly qualified Non Domestic Energy Assessor (NDEA) after an exhaustive inspection of the building's dimensions, fabrics, electrical and mechanical fittings etc. The Commercial energy perfomance certificate will provide the energy efficiency rating as well as a recommendation report containing measures that can be taken to improve the same. A Commercial Energy Certificate is valid for ten years. The ratings range from 'A' to 'G', with 'A' being the most efficient, and 'G' the least.

How is a Commercial energy performance certificate different from a domestic EPC?

An EPC for a commercial building as opposed to a domestic one is much more intensive and requires the NDEA to be highly technically qualified. Commercial EPCs are a lot more complicated since buildings such as factories could have different parts of their plans for different functions. Also, shops may have a separate area for a warehouse, and hotel rooms can be of different sizes. Consequently, the inspection takes much longer in the case of a commercial EPC, and it includes several steps such as these:

* General building observations including orientation and dimensions, kind of energy usage.

* Taking photographic evidence of various features.

* Taking detailed measurements of walls, floor and ceiling.

* Observing the type of heating and cooling in the rooms.

* Observing lighting in the rooms.

* Taking note of the ventilation provided.

Apart from the steps listed above, there are several more that are involved in a Commercial EPC survey. Once the data is collected, the EPC is processed using the Simplified Building Energy Model Interface (SBEM), which is a software to calculate the energy efficiency rating, and is Government approved.

Owing to the complexity that is involved in the process, and the differences in the types of commercial buildings, it is very difficult to predict a fixed cost for a Commercial EPC. However, it is quite obvious that they are expensive.

Why is a Commercial EPC important to have?

One of the primary goals of any business is to cut costs and overheads as far as possible. Energy is one of the largest factors when it comes to overheads. A Commercial EPC is very useful as it reflects the overall energy efficiency of the property and also provides recommendations on how the efficiency can be improved. By implementing these recommendations, a business can reduce the carbon dioxide emissions and increase the energy efficiency to a great extent.
