Residential housing management: meeting the challenge of the energy transition
According to the Observatoire de la performance énergétique du logement social, more than 70% of the bills concern heating consumption. A financial impact, but also an environmental one.

What is energy performance ?
The energy performance corresponds to the annual consumption of a building in energy: in particular electricity, water, gas. It depends on the quality of the structure, its mode of operation and its energy equipment.
The energy performance of a building is classified according to an energy scale ranging from A to G clearly indicated in the DPE (Diagnostic de Performance Energétique). It is this energy label that indicates the level of energy consumption of a home or building, as well as its rate of greenhouse gas emissions (GHG).
Energy performance: what are the challenges for housing providers?
The energy performance of buildings addresses first of all an environmental issue by considerably reducing a building’s carbon impact, as well as regulatory considerations.
A number of standards and labels have been promulgated to encourage the building industry to accelerate its ecological transition:
- The RT 2012 which imposes on new buildings (residential, public, tertiary) an annual energy consumption that must not exceed 50 kWhEP per m2.
- The ELAN Law which imposes, among other things, a reduction of at least 40% of energy consumption by 2030.
- The law on the ecological transition for green growth (LTECV) which provides, among other things, the renovation of 500,000 homes per year since 2017.
- The energy renovation plan for housing (PREH) which concerns existing buildings, including the BBC label (Bâtiments Basse Consommation).
The government deploys many schemes in the form of aid or tax credits to finance renovation work. We can mention MaPrimeRénov’ or the financing of part of the work by Action Logement for landlords and homeowners.
- However, renovation is no longer enough: we need to think about sustainable housing and have a long-term vision, in particular through the deployment of smart meters and the continuous monitoring of energy consumption.
In addition to the energy renovation of housing, many levers make it possible to measure and control the energy performance of residential housing.
Technological advances have made it possible to consolidate the concept of intelligent buildings. The aim is for the building to communicate data on the energy consumption of assets in order to measure their energy performance and effect energy savings. To do this, an interconnection is necessary by deploying intelligent sensors to automatically read the electricity, water and gas consumption, but also to detect any anomaly.
The concept of a connected building is also governed by the Ready2Services (R2S) standard. This standard defines the main stages of intelligent building to facilitate its implementation in the construction of new buildings or renovations. It applies equally to residential, multi-family and commercial buildings.
Smart building, smart city… the more buildings are connected, the more an ecosystem of services develops.
The Internet of Things and energy management platforms offer many opportunities to the building industry: energy performance monitoring, cost reduction, invoice control… This is where Energisme can provide you with a tailor-made answer through its N’Gage platform, specialized in the automatic collection and analysis of multi-fluid data.
