Abstract
Energy consumption in the social housing sector constitutes a major economic, social, and environmental issue, because in some countries such as France, social housing accounts for about 19% of the housing sector. In addition, this sector suffers from ageing, which results in high energy consumption, deterioration in the occupant quality of life, and high pressure on the budget of low-income occupants. The reduction of the energy consumption in this sector becomes a “must”. This reduction can be achieved through energy renovation and innovation in both energy management and occupant involvement by using smart technology. This paper presents a contribution to this goal through the investigation of the impact of smart monitoring on energy savings. The research is based on monitoring of comfort conditions in an occupied social housing residence in the North of France and the use of building thermal numerical modeling. Results of monitoring show that the indoor temperature largely exceeds the regulations requirements and the use of a smart system together with occupant involvement could lead to significant savings in heating energy consumption. The novelty in this paper concerns the use of comfort data from occupied social housing residence, occupation conditions, and building thermal modeling to estimate energy savings. The proposed methodology could be easily implemented to estimate heating energy savings in social housing buildings that lack individual energy consumption monitoring.

This paper presented an investigation of potential heating energy savings in a social housing residence
This issue is of high concern, because the social housing sector suffers generally from low energy performance, which lead to high energy consumption and high pressure on the budget of low-income occupants
Summary
Energy consumption in the social housing sector constitutes a major economic, social, and environmental issue, because in some countries such as in France, this sector accounts for about 19% of the housing sector This sector suffers from ageing, which results in high energy consumption as well as in high running expenses, degraded quality of life, and high pressure on the budget of low-income occupants. Analysis of the impact of buildings renovation on energy savings in two renovation programs in Grenoble, France showed that building renovation did not meet the expected energy savings, because of insufficient consideration of occupant behavior and lack of building monitoring [5] This result was confirmed by the research conducted by Juan et al on the energy use in the social housing sector in Spain [6].
