Non-Domestic Energy Certification
With the recent desire to reduce CO2 emissions and as part of the European Energy Performance Directive, the UK Government has introduced two levels of certification which apply to buildings in differing ways.
Display Energy Certificates (DEC) currently apply to public buildings with a total floor area of over 1000m2.
It is widely believed that over time the extent of these requirements will be increased to include all publicly accessible buildings.
Additional requirements in the form of Energy Performance Certificates (EPC) have been introduced for energy assessments of commercial properties prior to any lease or sale.
