The Energy Performance of Buildings Directive has resulted in a number of energy certificates that are required for buildings. Firstly any building that has an air conditioning system(s) over 12 Kilowatts must be inspected and issued with a report in accordance with CIBSE TM44. BEMS Energy is able to provide you with these reports for your buildings. Our CIBSE accredited inspectors have a wealth of knowledge and experience within the Air Conditioning and Building Services industry. We believe that this experience, coupled with our in depth building controls knowledge allows for a uniquely detailed report that will be of great benefit to your organisation. This report will help to reduce the Carbon Footprint and the running costs of the building services plant.

Since October 2008 EPCs have been required whenever a building is built, sold or rented out. BEMS Energy is again able to provide you with the required Certificate to ensure that your building complies with all legalisation.

Display Energy Certificates are only required for buildings with a total useful floor area over 500 m2 that are occupied by a public authority or institution providing a public service to a large number of persons and therefore visited by those persons. They are valid for one year. The accompanying Advisory Report is valid for seven years. BEMS Energy is able to provide your building(s) with a DEC to ensure full compliance with the EPBD.
