CWA 15693:2007

This CEN Workshop Agreement specifies a list of values of average saving lifetime, and/or an agreed methodology to establish these saving lifetimes, for commonly implemented types of energy efficiency improvement (EEI) measures in end-use. These saving lifetimes can be used in bottom-up calculations of energy savings, realized as result of policies and actions, as part of Directive 2006/32/EC on energy end-use efficiency and energy services.
This Workshop Agreement provides saving lifetimes in relation to the ESD, and does not supersede saving lifetimes used in Member States for other purposes. The CEN Workshop Agreement recognizes that there is variation in the saving lifetimes of Energy Efficiency Improvement (EEI) measures across Member States.
