All public buildings with a total useful floor area greater than 250m² are obligated to have a Display Energy Certificate (DEC) and advisory report. DECs are required to provide information about how energy efficient a public building is.
It states an energy rating from A-G and is based on the performance potential of the building (fabrics) and its services (heating, ventilation, lighting). The DEC comes with a recommendation report demonstrating how the energy performance can be enhanced.
Public Display Energy Certificates can only be produced by an accredited Energy Assessor and should be displayed no smaller than A3 in a prominent place clearly visible to members of the public. Fines can be issued for failing to display a DEC and failing to have a valid advisory report.
Over 1000m2 Must be renewed every 12 Months
250-999m2 Must be renewed every 10 years
