Minimum Energy Efficiency Standard for commercial buildings
The Energy Efficiency (Private Rented Property) (England and Wales) Regulations have now received approval from both Houses of Parliament and will ensure that buildings rented for commercial use in the private sector meet minimum energy efficiency standards.
GreenRock Energy are industry leaders in the field of reducing energy consumption for our clients. We have carried out over 10,000 Commercial Energy Assessments across the whole of the U.K.

Display energy certificates - dec public buildings
Display energy certificates and advisory reports for public buildings (dec).
Update: Now required for smaller public buildings
From the 9th July 2015 If you manage smaller public buildings (250m2 - 500m2) you will be required by law to have a valid Display Energy Certificate (DEC) and Advisory Report (AR).
Display Energy Certificates (DECs) are designed to show the energy performance of public buildings.
Any building occupied by a public authority and frequently visited by the public with a total floor area between 250m2 - 500m2 must have a valid Display Energy Certificate (DEC) and Advisory Report (AR). Both these documents are valid for 10 years.
Public authorities must display their DEC in a prominent place clearly visible to the public, e.g. near the building’s entrance. They can be fined £500 if they don’t.
DECs & Advisory Reports continue to be required for eligible buildings of 500m2 – 1000m2 and are also both valid for 10 years.
DECs for buildings of 1000m2 or more remain valid for 1 year and the Advisory Report for 7 years.
Only a fully accredited DEC Assessor can undertake and issue your certificate. As well as an on-site inspection, assessors may require a discussion with the building manager regarding energy efficiency energy management. It is necessary to provide a full 12 months' of electricity and heating bills to calculate the operational rating.
Our fully qualified and experienced DEC Assessors are based countrywide, providing a first-class, responsive service.
For further information or to book your DEC Assessment, call GreenRock Energy on 01225 753755.
When DECs are required
From 9 January 2013, if you are an occupier of a building requiring a DEC, you willneed to display a DEC showing an operational rating in a prominent place clearly visible to the public. You will also need to have in your possession or control a valid advisory report.
If you are a new occupier, or have been in occupation for less than 15 months by 9January 2013, you may not have the previous 12 months of meter readings availablethat are required for an operational rating. The legislation makes provisions forcalculation over the period of occupation in these cases.
Validity period of DECs
Where the building has a total useful floor area of more than 1,000m², the DEC is valid for 12 months. The accompanying advisory report is valid for seven years. Where the building has a total useful floor area of between 500m² and 1000m², the DEC andadvisory report are valid for 10 years.
Responsibilities for displaying a DEC
Under this legislation it is the responsibility of every occupier of a building affected by these regulations to:
• display a valid DEC in a prominent place clearly visible to the public at all times
• have in their possession or control a valid advisory report which conveys
recommendations to improve the building’s energy performance
This must be done for each of the buildings affected
An energy assessor, accredited to produce DECs, is the only person who can produce a DEC and advisory report for your building. It is acceptable for employees to produce DECs provided they meet the standards of and are accepted by an accreditation scheme.
Firstly the energy consumption data provided will be reviewed by the energy assessor in line with the approved methodology. Under certain conditions, the methodology allows adjustments to be made for longer hours of occupation, variations to weather and climate and allows certain activities to be separated if they are not typical of the type of building (separable energy uses).
The carbon dioxide emissions for the certificate are based on the adjusted energy consumption and adjusted total useful floor area and building type to give a measured CO2 emission per square metre.
The energy assessor will then use an approved tool to calculate the operational rating and produce a DEC and advisory report from the information gathered in line with the approved methodology.
DEC's Within an ESOS Assessment
Buildings occupied by public authorities and institutions providing public services , as well as buildings that are frequently visited by members of the public, which have a total useful floor area (TUFA) of over 1,000m2 are required by law to display a DEC. However, a voluntary DEC can still be beneficial for many businesses even if not under mandatory issue, to demonstrate the energy efficiency of a given building. For instance under the new government legislation for large companies and industry, ESOS (Energy Savings Opportunity Scheme) a DEC is acknowledged as a relatively low cost route to compliance as part of a company’s evidence pack for submission for ESOS.
A DEC shall constitute an ESOS compliant energy assessment for the aspects of energy consumption within a building which it covers, provided:
• it is still valid on the compliance date of a compliance period; and
• the assessment has been undertaken and the certificate issued (and accompanying recommendation report provided) within the compliance period.
A DEC assessment will measure the total amount of energy used by a building within a 12 month period. This will include any electricity and gas consumed, as well as fuel stores (such as coal, oil etc) where applicable, in order to provide a banded OR (operational rating) from A-G, with A being the most efficient.
