Notes: 1) Values are taken from a selection of completed and ongoing preparatory studies and may be subject to change. 2) Impacts and savings mentioned may be overlapping (e.g. ventilation and CH

boilers, motors and their applications). 3) Ventilation impacts show 2 numbers: the first is the electricity consumption, the second shows the (heating) fuel savings. 4) 'Other impacts' means that aspects

were taken into account/ studies, not necessarily --e.g. due to lacking test standards-- (already) translated into requirements. Items with a ‘?’ are or could be subject of ongoing pstudies (no Commission
