Display Energy Certificates (DEC) are applicable to all public buildings with a total useful floor area greater than 250m². DECs are required to provide information about how energy efficient a public building is.
Similar to an EPC, the building will receive an energy rating from A-G and is based on the performance potential of the building fabric and HVAC services. This rating directly correlates to actual building running costs that our surveyors will accumulate from 12 month’s utility bills.
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 250m² and 1000m², the DEC and advisory report are valid for 10 years.
