Display Energy Certificate

What is a DEC?

A Display Energy Certificate (DEC) shows the actual energy usage of a building, the Operational Rating, and helps the public see the energy efficiency of a building. This is based on the energy consumption of the building as recorded by gas, electricity and other meters. The DEC should be clearly displayed at all times and clearly visible to the public. A DEC is always accompanied by an Advisory Report that lists cost effective measures to improve the energy rating of the building.

When are DEC's required?

DEC's and advisory reports are required for buildings with a total useful floor area over 1,000m2 that are occupied in whole or part by public authorities and by institutions providing public services to a large number of persons and therefore frequently visited by those persons.

DEC's are valid for one year. The accompanying Advisory Report is valid for seven years. The requirement for Display Energy Certificates came into effect on 1 October 2008.

Architectural Plans

Many building facilities managers are faced with the problem that either no plans exist for buildings in their charge or only archaic imperial paper copies of poor quality are available. We can organise the production of metric scaled plans in conjunction with an EPC or DEC survey, thus reducing the cost of subsequent energy surveys.

These can either be standard RICS style floor plans or fully dimensioned CAD based Architectural drawings.

Charges for these two types of plans would be an additional charge in addition to the EPC fee for basic floor plans or a per square meter charge for the CAD based service.
