Energy-efficiency of buildings

The Shift Project has assembled a working group of specialists and professionals to discuss thermal renovation of buildings, a phase which constitutes an imperative step towards decarbonizing the economy. Having identified the reasons explaining why public policy measures have failed to have a satisfactory impact on the annual rate of renovation, the working group outlines a global action plan to structure renovation professions and markets.

 

Proposals

The working group recommends, among others:

- a regulatory framework for a renovation spread out over time, according to the type of housing;

- revision of existing thermal regulations for buildings;

- a complete overhaul of priority targets for public financial aid, to redistribute public funds that are currently allocated to ineffective incentives;

- training and qualification in thermal renovation for building trades so that artisans can offer the most effective services.

 

Publications

The first report was released september 2012 and presented to several ministerial hearings during fall 2013. The ministries demanded a series of notes to be presented January 2014, which The Shift Project produced. The output will be presented to the Prime Minister’s Cabinet and to the parliamentarians February 2014.

The conclusions of two working groups on 1) the modelling of collective housing and 2) the renovation passport will be publicly released during spring 2014.

The issue dealt with

A substantial reduction in fossil fuel consumption in industrialized and emerging countries cannot be achieved without significant energy savings from the built environment. In France, if the building sector is to play its part in Factor 4, it will be mainly in the domain of heating.

We cannot rely entirely on new build, that much is clear: the rate of renewal of the building stock is well below 1% per year. Moreover, only a third of new houses are built on the site of older, demolished, buildings; the other two thirds correspond to an expansion in the building stock.

A massive reduction in CO2 emissions in the building sector will therefore depend predominantly on the energy-efficiency renovation of existing stock. There are many barriers, however, to implementing such an initiative: the intrinsically low return on investment (mainly due to the weakness of energy prices), too few trained builders, too little capital available for the buildings that are eligible for renovation, difficulty freeing up premises to do the work, lack of a regulatory framework in a number of countries, complexity of working on jointly-owned properties, etc.

 

Working group

The project is led by Brice Mallié, who has 15 years’ experience in consulting. The working group includes professionals in the construction sector (Fédération Française du Bâtiment, Groupe Bouygues) and in on-the-job training programs, regulatory specialists (Plan Bâtiment Grenelle), industrial companies (Saint-Gobain, Rockwool), energy companies (EDF and GDF Suez), research units (Enertech and Pouget Consultats), expertise banks (BPCE), and more broadly technical experts in thermal renovation. The group has drawn upon the practical knowledge of its members, and feedback from programs conducted in other European countries (Green Deal in the U.K., KfW in Germany).

Baptiste Bernier joined the working group since November 2013 as Project Assistant.

 

Timeline

The final report was made available in late June 2013, and submitted to the secretariat of the National Energy Transition Debate.

The first report was released September 2012 and presented to several ministerial hearings during fall 2013. The cabinets demanded a series of notes to be presented January 2014, which The Shift Project produced. The output will be presented to the Prime Minister’s Cabinet and to the parliamentarians February 2014.

The conclusions of two working groups on 1) the modelling of collective housing and 2) the renovation passport will be publicly released during spring 2014.

 

Conferences

A conference on the study findings was held on February 18, 2013, during which specialists and professionals met in two round-table discussions.

Brice Mallié was also given the opportunity to present The Shift Project’s work to the DHUP (Housing, Urbanism and Landscape Delegation of the French Government) on demand of the Monitor, to Avenir et Énergies (Future and Energies), RBR 2020 (Reglementation Building Responsibility) and several times as part of the Nouvelle France Industrielle (New Industrial France) between June 2013 and February 2014.
