Greenoke (ESOS) Ltd is able to provide businesses and commercial property owners with a number of services to improve their energy efficiency and raise their profile using specific strategies, products and energy efficiency initiatives.  For more information about our consultancy services please see below.

Non Domestic or Commercial Energy Performance Certificates

Commercial or Non-Domestic Energy Performance Certificates (NDEPCs) were historically required Commercial EPCfor when business premises were sold or let and more recently have been required if businesses want to apply the Feed in Tariff (FiT) for Solar Photovoltaic installations.

The EPC details the energy efficiency of a property based on its business usage, internal area usage, age, size and construction, as well as the Heating, Ventilation, Air-Conditioning, Lighting, Glazing and Insulation. The report provides a rating from A (excellent) to G, as well as a recommendations report which details low, medium and high cost opportunities for the property owner/tenant to improve the energy efficiency of the property.

The Assessment involves an on-site survey which will require the assessor to visit all parts of the property. The Assessor will take measurements and inspect key energy using aspects of the property. The Assessor will then perform the key calculations off site and the data will be entered into the government approved system and the report generated.

An EPC lasts for 10 years, or until a significant change is made to the property, which would change the score or rating of the property.

It is worth noting that as from 2016, landlords will have to agree to reasonable energy efficiency improvements to their properties as requested by tenants, and that in 2018 no landlord will be able to rent out a property with an F or G rating.

Display Energy Certificates

The Energy Performance of Buildings Regulations introduces the requirement for DECs in public buildings by 1st January 2009. From this date a DEC must be prominently displayed in non-domestic DEC Page imagepublic buildings with a gross floor area over 1,000 m2 (this is the area measured from the internal face of your external walls). From 1 January 2013 DECs were required for all such buildings of over 500 m2 and from July 2015, all such buildings of over 250 m2 will also require one.

In the context of these Regulations a public building is one occupied by public authorities or institutions providing public services to large numbers of persons, for example:

  • Central Government,
  • Local authority
  • NHS buildings etc.
  • Buildings such as leisure centres,
  • Theatres and galleries providing services from public funds

Recent changes have reduced the requirement to only those buildings which are frequently visited by members of the public and useful guidance on this criteria is provided in the Communities website DEC FAQ section. Smaller buildings will also be ‘caught’ by the Regulations on a site where they have a combined floor area exceeding 1,000 m2 and are connected by a conditioned (heated, cooled or mechanically ventilated) space.

The Display Energy Certificate will convey the Operational Rating of the building, indicating its energy efficiency and CO2 emissions on a scale of A to G. The Operational Rating will indicate how well the building is being managed and operated. Display Energy Certificates are based on the building’s energy consumption, so if you are responsible for a public building affected by the Regulations you should start to gather the data (from meter readings and/or energy suppliers) without delay. Estimated consumption data from energy suppliers can be used during the initial implementation period.

A Display Energy Certificate will convey all the information necessary for the public to take a view on the building’s energy performance and most importantly it will include advice for improvement. A DEC will remain valid for one year and the Advisory Report will remain valid for seven years.

BREEAM In-Use AssessmentsBREEAM Logo

BREEAM (The Building Research Establishment Environmental Assessment Methodology) In-Use is a scheme to help buildings managers, owners and occupiers reduce running costs and improve the environmental performance of existing non-domestic buildings. It is a voluntary independent certification process that provides a clear and credible route map to improving sustainability credentials of existing buildings. The Bream In-Use scheme is recognised and implemented worldwide.  BREEAM In-Use assessments must be reviewed annually and repeated in full on a 4 yearly basis.

Energy Efficiency and Low Carbon Consultancy

Many of our clients  are looking to reduce the costs of running their businesses and energy is often a key area where savings can be made.  Using our formal assessment procedures and extensive Low Carbon Consultant logoknowledge of energy efficiency opportunities we can provide our clients with consultancy, advice, implementation planning and project management services.

Greenoke (ESOS) Ltd is able to provide businesses and commercial property owners with a number of services to improve their energy efficiency and raise their profile using specific strategies, products and energy efficiency initiatives.

ISO50001 Audit

ISO 50001 is an energy management system (EnMS) that helps organizations in all sectors use energy more efficiently.

Using less energy to do the same or more work, reduces costs, significantly increases profits and reduces your business’s climate change impacts.

ISO 50001 is based on the management system model of continual improvement also used for other well-known standards such as ISO 9001 or ISO 14001. ISO50001 offers organisations a framework to:

  • Develop a policy for more efficient use of energy
  • Fix targets and objectives to meet the policy
  • Use data to better understand and make decisions about energy use
  • Measure the results Review how well the policy works
  • Continually improve energy management

Commercial Green Deal Assessments

This evaluates the business process undertaken in the building to create an energy saving policy with recommendations.  Also it has to cater for the default EPC inferences to be altered to a superior reflection of actual building use designs. This second assessment will consider efficient administration routines; fuel duty information and notable energy use where needed.

The amalgamation of a further bespoke frameworked evaluation; categorical energy use information as to how the building is used, which permits the consultant to provide the client with the most up to date advice to allow transaction resolutions to be carried out.
