Display Energy Certificate (DEC)

Display Energy Certificates (DECs) are designed to show the energy performance of public buildings. DECs last for 1 year. A DEC certificate shows a buildings  Operational Rating, it represents CO2e emission per meter squared.and states an energy rating from A-G 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.
