In hotel, the usual indicator is the electricity consumption per person-night, i.e the ratio between the electricity consumption and the number of person-night (kWh per person-night).
In the health sector, the usual indicator is the electricity consumption per bed, i.e. the ratio between the electricity consumption and the number of beds occupied in hospitals (kWh per per bed).
These indicators also combine the effect of energy efficiency improvement but also of increase comfort and labour productivity.
4.2.1.4. Specific energy consumption per m2
The specific consumption per m2 is defined for service sector’s sub-sectors as the ratio between the energy consumption of the sub-sector and the floor area of buildings. 10 EL/EMP: electricity consumption divided by employment; EL/VA: electricity consumption per unit of value added; EL/IPI: electricity consumption by production index; EL/PNIGHT: electricity consumption by number or persons-nights; EL/NBED: electricity consumption by number of beds in hospitals.
4.2.2. Bottom- up indicators
Two types of bottom-up indicators can be considered in designated buildings: - Indicators of specific consumption per unit of activity (e.g. kWh per person-nights in hotels, and per bed in hospitals); - Indicators of specific electricity consumption per m2 by type of buildings.
These indicators will be calculated for electricity and for fuels (mainly LPG separately).
4.3. Data for service sector
Energy consumption and activity data will be included by sub-sector
4.3.1. Energy consumption
Electricity consumption by sub –sector is monitored by EPPO
4.3.2. Activity data
The activity data required in services are: o The value added by sub-sector for the three main sub-sectors: wholesale and retail trade, hotels and restaurants, and health and social work activities. o The industrial production index for the three main sub-sectors o The number of employees by sub-sector for the three main sub-sectors; o The floor area size (m2) in hotels and hospitals; o The number of beds for hospitals and number of person-nights for hotels,
The floor area represents the floor space that needs to be cooled or illuminated; it is measured in m2 .
The employment is usually expressed in full-time equivalent (Full-time equivalent employees equal the number of employees on full-time schedules plus the number of employees on part-time schedules converted to a full-time basis).
