Installation of a lighting management system for the facades and windows of 10 stores

In order to reduce the GHG emissions of 10 of its Asian stores, Louis Vuitton has set up a system for controlling electricity consumption (lighting management system for facades and stores windows).

Project objectives

  • To reduce electricity consumption linked to the lighting of stores as well as the associated CO2 emissions.
  • To commit Louis Vuitton teams
  • To bring visibility on climate commitment in stores
Detailed project description

For the Maison Louis Vuitton worldwide, stores account for 82% of greenhouse gas emissions linked to electricity (and 70% of electricity consumption).

Among these stores, the 2 Taiwanese stores and 8 Chinese stores are particular in two respects:

  • They are located in countries where electricity is very carbon-intensive (500 gCO2 / kWh for Taiwan and more than 700g CO2 / kWh in China),
  • They have particularly large facades and windows.

The interest of the project launched by Louis Vuitton is to install, in each site, a lighting control for facades and windows connected to an electronic timer. The slots during the switch off of the lights have been planned (especially at night). No human intervention is necessary, everything is automatic.


This initiative will result in an overall energy saving estimated at 538 MWh per year (408.8 MWh in Chinese stores and 129.2 MWh in Taiwanese stores). It should prevent the emission of 395 metric tonnes of greenhouse gases each year.

Note: this project is the result of the program launched by Louis Vuitton which allows each year the environmental community of the zones, called “Green Team”, to highlight non-budgeted initiatives by presenting them to Michael Burke, the President of the House. In 2019, 19 projects were financed by Louis Vuitton on behalf of the LVMH Carbon Fund.

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 – Switch off of facades and windows at night.

Illustrations of the project

This project contributes to SDG 12 Responsible consumption and production.

Through this project, the 10 stores are reducing their energy consumption, thereby raising employees’ awareness of more sustainable consumption patterns.

This system can be replicated in each store, the carbon impact depending on the country’s energy mix (the more the country is carbon intensive, the greater the emissions are avoided).

Regular adjustment of the system is necessary to synchronize the opening / closing times of the store with the switching off / on of facades and windows.
