Energy savings of 22 to 56%: results of experiments on pilot buildings under the HOMES program in associationwith the French Electrical Contractors’ Association (FFIE)
Over the past 20 months, a series of experiments conducted on 5 pilot sites by the
HOMES program and the FFIE have produced exceptional results in terms of energy
savings. As well as identifying several improvement drivers, the initiative has also
unlocked the potential for commercializing a number of prototype technical
innovations.
To reduce the energy consumption of equipment and systems in buildings, the HOMES program has defined 150 control functions based on 2 key principles:
> Reduction of the energy demand in each room based on the room's occupancy and levels of activity, using a "multi-application" approach which combines and optimizes all the energy-consuming equipment
> Secondly, optimization of the energy supply on the 3 energy vectors which feed a building: electrical systems, water systems (heating, hot water, etc.) and ducting systems (ventilation, etc.)
Using these active control solutions, it has been possible to measure a considerable reduction in energy consumption at the pilot sites.
> Montbonnot primary school (Isère region): 56% saving in energy consumption, mainly by controlling the air quality and the thermal comfort (according to the occupancy level - which is very intermittent), and by controlling the heat production according to the requirements of the classrooms.
