EPCs for Commercial Buildings

Improving the energy rating of a building

There are a number of considerations for improvements to non-dwellings: (all information provided courtesy of the Carbon Trust):

Budget and resources for the project
In most cases a business case will be required. This is likely to focus on cost and financial return (eg payback period, based on energy and other cost savings), but may also include other benefits such as meeting regulations, improved environmental performance and corporate reputation, or better staff working conditions.

Consequential Improvements
The Consequential Improvement requirement applies to proposed work in buildings over 1000m² which consists of:

• an extension
• the initial provision of any fixed building services such as heating, ventilation or air handling
• an increase to the installed capacity of any such fixed building service.

If the criteria apply then the building will be required to comply with the Building Regulations but only if the work is technically, functionally and economically feasible. For more information if you think you may be affected. See Approved Document L2B at: www.planningportal.gov.uk.

Requirements
Improvements may include the purchase of equipment – do you know the exact make and model you need? If not, you may need to undertake research and talk to suppliers before producing a shortlist of options and then preparing a product/project specification that clearly defines your requirements.

Knowing which suppliers, installers and/or contractor to use
The next step is to identify potential suppliers to approach for quotes. Where possible contact vendors that have been recommended to you. If this is not possible, contact trade associations representing suppliers of the products you require. Alternatively if you know which equipment you need, but are unsure of an installer, contact the equipment manufacturers and ask them to provide you with a recommendation.
