NEWS: Prepare for DEC floor area threshold decrease to 500m2 in 2013.
A DEC will provide energy ratings of a building based on the actual amount of metered energy used by the building over the past 12 months. It will show the operational rating, carbon dioxide emissions and previous operational ratings from the last three years. This certificate must be displayed publically and needs to be accompanied by an advisory report.
Your DEC will become invalid every 1 year and your advisory report will need replacing every 7 years.
