Sustainable Buildings approach: Improving the energy and environmental efficiency

Vivendi has implemented a “Sustainable buildings” program aimed at improving the energy and environmental efficiency of its buildings, thereby reducing the carbon footprint of the sites.

Project objectives

The objectives of the "Sustainable buildings" approach are to reduce the environmental footprint linked to the use of sites via: - Raising employee awareness about “green” energy practices (and generally good environmental practices), in order to fully involve them in the process; - The guaranteed optimal compliance with environmental regulations, and in particular those relating to infrastructure equipment (lighting, air conditioning systems, heating); - Optimization of the site's operating processes and equipments in order to reduce the associated energy consumption (electricity, steam, etc.) and reduce the greenhouse gas emissions generated by them.

Detailed project description

The “Sustainable buildings” approach deployed at the Group’s headquarters consists of a set of actions aimed at guaranteeing optimal use of energy on the site. This is reflected in particular by the following actions:

– Implementation of a dual ISO 14001 (environmental management) & ISO 50001 (energy management) management system, including the deployment of an environmental and energy policy accompanied by indicators allowing a thorough management of the energetic performance ;

– Establishment of an environment and energy “Green Team” (also composed of site service providers) whose role is to lead and continuously improve the efficiency of the environmental and energy management system;

– Launch of regular information campaigns for site employees related to eco-gestures (poster campaigns, creation of an e-learning module dedicated to the environment-energy approach, events, etc.);

– Implementation of actions on infrastructure equipment: relamping campaigns, more precise control of heating and air conditioning, implementation of sub-metering systems to improve the tracking of of energy consumption, optimization maintenance actions (removing sludge from circuits, etc.), removing or replacing obsolete equipment with more efficient devices, etc.

– Optimization of waste sorting channels ;

– Systematic integration of an analysis of the potential energy gain in the specifications of all works carried out on site.

Emission scope(s)

on which the project has a significant impact

Scope 1

Direct emissions generated by the company's activity.

Scope 2

Indirect emissions associated with the company's electricity and heat consumption.

Scope 3

Emissions induced (upstream or downstream) by the company's activities, products and/or services in its value chain.

Emission Removal

Carbon sinks creation, (BECCS, CCU/S, …)

Avoided Emissions

Emissions avoided by the activities, products and/or services in charge of the project, or by the financing of emission reduction projects.

Scope 2 Optimization (process and material) of site equipment – Relamping

  • Scope 2 emissions:

    Electricity and steam 2015: 336 tCO2eq / year

    Electricity and steam 2019: 263 tCO2eq / year

    or a reduction of nearly 22% in CO2eq / year emissions in absolute value.


    NB: the figures for 2020 are considered not to be representative, the COVID situation having led to the closure of the site for several weeks.

Electricity emission factor from the network in France = France – Electricity – 2018 – average mix – consumption> 0.0571 kg eqCO2 / kWh

Illustrations of the project

The “Sustainable Buildings” program contributes to the following SDGs:

– SDG 7 Clean and affordable energy by improving the energy efficiency of the building stock;

– SDG 9 Industry, innovation and infrastructure: making more rational use of resources and environmentally friendly materials;

– SDG 11 Sustainable cities and communities by improving air quality;

– SDG 13 Measures relating to the fight against climate change.

The “Sustainable Buildings” program, based on internationally recognized management standards, can be reproduced on all of the Group’s sites. The environmental benefits and the ROI may vary depending on the size of the site, the operational control status exercised (owner or tenant) and the initial energy performance of the site.

Its deployment also requires a strong commitment from Management as well as the designation of a dedicated resource to oversee the action plan.
