requiring Display Energy
The purpose of introducing
Display Energy Certificates (DECs) is to raise
public awareness of energy use and to inform
visitors to public buildings about the energy use of
a building. DECs provide an energy rating of the
building from A to G, where A is very efficient and
G is the least efficient and are based on the actual
amount of metered energy used by the building over a
period of 12 months.
Public authorities, and
institutions providing public services to a large
number of persons, who occupy space in a building
with a total useful floor area greater than 1000m2,
must display a valid display energy certificate
("DEC") at all times and have a valid advisory
report in their possession.
Only public authorities or public
institutions (those providing services traditionally
associated with local or national government)
occupying a building must display a DEC. Other
private occupants of the same building are not
required to display a DEC.
The DEC is valid for twelve
months and is required to be updated annually. The
Advisory Report which contains recommendations for
improving the energy performance of the building and
its energy usage is valid for seven years.
does it cost?
Display Energy Certificates need
to be quoted individually for each enquiry. This is
due to the differing complexity of the buildings and
also the amount of data that needs to be gathered
during the site survey.
