May 2005 (on going)
Territorial scope

Target buildings  




Public buildings

 New buildings    

Private buildings
 Existing buildings
 Industrial, services, etc.

Main Targets by 2020

·      20% reduction of energy consumption and GHG in all territory;

·      Increase renewable energy production to reach 21% electric consumption from renewable sources, and 26% of urban heat consumption also from renewable sources.
Main Targets by 2050  
    ·      Adopt a regional position in accordance to the Factor 4 process, which corresponds to emissions below 2 teqCO2/year/capita

·      Divide by 4 the GHG emission by 2050

Grenoble-Alpes Métropole was the first region in France to sign a Climate Action Plan. This pioneering action launched in 2005, combines local authorities, government agencies, housing authorities, energy suppliers, universities, associations and businesses.

The local climate plan sets targets for reducing emissions of GHG for the years 2020 and 2050 on the territory of Grenoble Alpes Métropole which has committed to go beyond the European objectives. The second phase of the plan started by adopting a new charter consistent with global issues of climate and energy, in which all partners are invited to commit to quantitative targets for reducing emissions of GHG and energy consumption and promoting renewable energy.

The local climate plan has three main goals, which are:

·      Engage key stakeholders: the partnership approach, to mobilize the local actors around common objectives, and make their actions visible and coherent. The coordination, assistance and monitoring are provided with the assistance of the local agency for energy and climate. The observatory monitors consumption and emissions on the territory. All the partners meet in a forum every six months. The scientific council, composed of renowned experts in the fields of science, technology, economics, finance, sociology, urban planning and housing, advises the Metro for its policies to aim for the Factor 4.

·      Implement the action plan of the Metro: the internal process, to meet the commitments of the Metro. It is structured by the Cit'ergie label

·      Engage citizens: the public process, to mobilize, support, and inspire action for the citizens.

After the presentation of the Climate Plan strategic objectives and the interaction of monitoring carried out by the Climate Observatory as one of the main outputs of this Plan, to track consumption and emissions of GHG on Grenoble territory, is already possible to observe the results and note that the impact of public policies concerning the residential sector is difficult to evaluate.

In fact, the residential sector is a priority in Grenoble-Alpes-Métropole policy implementation effect of the Climat Plan. This priority is focused on 4 project axis (public and private new construction and public and private refurbishment) under the following objectives:

§  Reduce energy consumption for heating house needs with focus on reducing the needs to the buildings envelope improvements;

§  Fight against energy precarity by mobilizing territorial actors on both new construction and rehabilitation programs.

As part of its housing/lodgment jurisdiction and as prime contractor for the local housing program (LHP) the Grenoble-Alpes-Métropole has an active policy support for the social housing developments, and its also conducting a policy to support the refurbishment of public and private park.

Since the launch of its Climate Action Plan in 2005, the Métropole has determined as one of its main priorities to enhancing the buildings environmental qualities.

This environmental policy applied to the jurisdiction of the urban community housing has resulted in the design and implementation of the following measures:

Ø New construction - public park

In anticipation of the new thermal regulations that will be apply until the end of 2012, the Métropole wished to encourage and support the social public houses lenders to refurbish their houses in order to meet the energy performance ambitions beyond existing regulatory requirements. According to this measure, from 2008 the Métro has offered financial assistance to contribute to over-investment induced by the construction of social houses that were categorized by THPE 05 then BBC (Low Consumer Building).

Ø New construction - private park

In line with the previous procedure, the Métro has created a working group called "Climate and Urban development" involving the Metro officials services of planning/environment of suburban districts to promote the inclusion under private developments operation of environmental quality aspects (energy, air quality, noise, water management, and climate change adaptation).

In terms of environmental impacts, the existing housing stock whether private or public is a major issue that can reach the goals of energy consumption and CO2 emissions reduction by 2020. For this reason, the Metro has implemented the following features:

Ø Rehabilitation - public park

The rehabilitation of public park is a supported subject to compliance with an established reference work document under the achievement of a renovation performance level goal of BBC (Low Consumer Building) of 96 kWh/m2/year after works. The objective is to achieve a reference number of 500 lodgments renovation, with a 3.6 million euros budget over the 2010 to 2013 period.

Grenoble municipality stipulated an allocation of 10% of the municipality's investment budget to energy conservation measures in order to achieve a 30% reduction in overall energy consumption by 2014. As far as municipal buildings are concerned, a refurbishment programme was set up to deal with the 25 most energy-intensive buildings which are responsible for 75% of all municipal buildings' consumption.

Ø Rehabilitation - private park

With the aim to encourage the insulation reinforcement in private buildings that were built between 1945 and 1975, the Métro launched in 2010 a new device insulation campagne denominated Mur/mur, with 17.3 million euros to cover this sector under the period 2010-2013. The funding conditioning should be in observance to an obligation to reach a performance BBC renovation level (96 kWh/m2/year).
