MEASURES TO IMPROVE ENERGY EFFICIENCY

compared with 2016 due to adverse weather conditions at the end of the year. It is used entirely for tanning processes during the week and is injected back into the grid onweekends. Gas cogeneration used to simul- taneously produce hot water and electricity worked throughout the year. Lastly, the Montereau and Vivoin tanneries continued implementing improvement plans determined by regulatory energy audits performed in the second half of 2015. Textiles At each production plant, the equipment was modified and programmed to limit energy consumption. At ITH the temperature regulation systems (Rooftop) were replaced by more economical systems; this modification was made in response to the energy audit conducted on the site in 2016. The combustion and process equipment was modified and programmed to limit energy consumption, in particular on the Ateliers AS and SIEGL sites, which are the main consumers. The installation of economisers on the boilers, variators on the primary pumps and shutdown of the boiler room on weekends are a few examples of the optimisations that were achieved. The modernisation programme for SIEGL’s treatment plants, which was launched in 2016, also had impacts on the site’s consumption of electri- city. This was due to two major factors, namely: channelling our effluents to a smaller tank, which allowed us to reduce the number of homogeni- sation devices, and replacing filter membranes with new, more efficient technology. With respect to gas, thedivisionachieveda2%decrease in consumption. This result is due to the replacement of the vaporiser at SIEGL which, in spite of a period of tests involving overconsumption, enabled the facility to reduce its annual consumption once the situation hadbeen stabilised. As a result of the initial results achieved, we expect to be able to save 5% during the course of 2018. At the AEI site, the replacement of an old boiler by more efficient technology also means that we can expect to reduce our energy consumption in 2018. The division also pursued its programme of deploying LED lighting; the printing and weaving workshops are now equipped (colour, fixing, and rinsing facilities, and printing lines) and we will gradually be completing the deployment of these solutions in the offices and meeting rooms. As the use of lighting represents approximately 10% of our electricity consumption, this remains an important issue for the division. Finally, our activities involve a high degree of interdependence between water consumption and energy consumption, since we heat most of the water that is consumed. As a result, when we are able to maintain a high degree of control over one of these parameters, this can actually have an impact on the other.

Leather Goods In the context of designing new leather goods, special attention was paid to environmental impacts and more particularly to energy consumption. Anticipative work organised around four areas of work: s energy consumption: this parameter is one of the main challenges of the technical programmes for the new Leather Goods division. Once the project is launched, various solutions are envisaged and thermal simulations are carried out by specialists from design firms commis- sioned for the project. Based on the results, the solution that is most suited to the project is selected. For example, the building of the last Leather Goods division put into operation at the end of 2017 (l'Al- lan production unit), was constructed ensuring that it met the highly demanding level of the HQE (High Quality Environmental standard) label, i.e. it exceeded the objectives of the 2012 Thermal Regulation standard by 30% (regulation laid down at the Grenelle Environment Forum, which aims at limiting the primary energy consumption of new buildings). To do so, reinforced thermal insulation and sealing were carried out on solar installations for the production of hot water and optimum output equipment (heat pump, etc.); s energy management tools: as soon as the new Leather Goods divi- sion is put into operation, meters are positioned and dedicated sof- tware is set up to control energy consumption and the identification of possible drifts as accurately as possible; s employing renewableenergy productionsolutions: theLeatherGoods division put into operation (l'Allan production unit) has a park of photo- voltaic panels for generating electricity of up to 152 kWc for own use. Nontron has a thermal solar power system that provides 100% of the hot water consumption in washrooms; s minimumconsumptionbyequipment:theenergyimpactoftheequip- ment was introduced as one of the decision-making criteria in the context of the machinery investment strategy for the leather métier. As such, new equipment introduced in the new Leather Goods divi- sion but also in existing ones, ismore energy-efficient. This approach can be implemented through a partnership with suppliers. Tanneries The tanneries are working to improve the energy efficiency of their facili- ties. For example, the tannery of Vivoin continued its work on the thermal insulation of buildings and optimised control of the hot water network. The Tanneries du Puy also worked to reduce heat loss when supplying hot water to production areas with the installation of a re-circulation loop. At Cuneo, electricity production from 296 photovoltaic panels installed on the roof of the tannery totalled 59 MWh, representing 8% of the site’s total electricity consumption in 2017. The production was down slightly
