The energy efficiency certificate (EEC) is an official document drawn up by a competent technician that includes objective information on the energy characteristics of a building.
The ECE qualifies a building in terms of energy by calculating the annual energy consumption required to meet the energy demand of a building (including hot water production, heating, lighting, cooling and ventilation).
The energy rating scale is a seven-letter scale and varies between the letters A (most energy-efficient building) and G (least energy-efficient building) and is reflected in the Energy Label.
