The certificates must include details of the relevant building’s performance and reference values so that the owners or tenants may assess comparability of energy performance with similar properties. Cost evaluation must include an assessment of energy savings and underlying energy prices, together with a preliminary price forecast. Labels may provide estimates for payback periods based upon cost optimal savings. For apartments or for units designed for separate use in blocks, certificates may be based on either a common certification for the whole building or upon the assessment of a similar building unit with the same energy relevant characteristics.
