In the context of the current process of reflection on the New National Programme for Urban Renewal (NPNRU) neighbourhoods, the City of Paris entrusted Apur with the mission of assessing the Climate Plan consumption objectives of 80 kWh/m²/year per unit and 60% reduction of energy consumption by the HBM housing stock.
HBM housing is a sector of the housing stock with quite specific construction characteristics. It lies somewhere between old building methods from which it inherits numerous aspects and modern construction of which it uses certain building techniques notably reinforced concrete.
The Apur study carried out for the City of Paris Department of Housing and Habitat in partnership with the housing organisations Paris Habitat, RIVP and Elogie-SIEMP, proposes an analysis of the first Climate Plan operations carried out on the HBM housing stock. The study proposes capitalising on feedback from operational experiences by visiting construction sites, interviewing Project Managers -MOA-, Project Contractors -MOE- and Technical Design Studios -BET-, analysing energy diagnoses and a collection of maps and diverse data made available to Apur.
The study is organised in 3 notebooks:
- The first deals with the spatial evolution of the housing stock since its creation. It describes the various interventions on the morphology of the ensemble, on exterior and interior areas of premises, which enabled HBM to adapt to new comfort standards and requirements;
- the second looks at the technical aspects of these interventions specifying the initial characteristics of the buildings and the technical procedures carried out. The impact of these initiatives is assessed using feedback on experience and a detailed analysis of energy audits;
- the third proposes that the scale of measures carried out be broadened in the context of the Climate Plan operations by highlighting approaches and procedures as yet largely unexploited which could contribute significantly to improving the environmental impact of this sector of the housing stock.

This study follows on from the historical study on the HBM housing stock carried out by Apur in 2017 called : “Low cost housing on the outskirts of Paris -La Ceinture-: a historical study”
