The certification, which recognises our daily commitment to reducing our environmental impact, was renewed in 2015.
This commitment can be seen every day through the following actions:
LED lighting and motion detectors for more energy-efficient car parks
Between lighting, lifts and ventilation systems, Saemes car parks consume more than 10 million kWh every year. Since 1 January 2015, our electricity comes from entirely green sources (solar panels, wind power, etc.)!
Saemes has replaced its fluorescent lighting with LEDs, which consume 30% less energy. In all, more than 10,000 LEDs have been installed, accounting for half of all lighting installations. Additionally, motion detectors have been installed to better adjust lighting use to actual needs while ensuring the lighting quality our customers expect.
All of these actions, along with increased awareness and participation from our employees, have helped us reduce our energy use by 16% since 2011. This translates to 2 million kWh per year, which equals the annual energy use of 283 households.
Reducing water consumption
Saemes has purchased new floor scrubbers that consume 70% less water than previous models in order to save water.
Water-saving efforts also include the elimination of water bottles at car parks. Tap water, filtered and regularly controlled, is offered instead of bottled mineral water that must be transported by lorry over hundreds of kilometres.
Water and electricity usage is regularly controlled during car park renovation and construction projects. Water recovery and filtering systems have also been installed.
Minimising construction site pollution
Saemes sets up an environmental oversight programme at every construction site to limit noise pollution and improve waste management.
Dust control precautions are taken at all sites (water spraying, etc.).
A Waste Planning and Disposal plan was created to evaluate and classify waste quantities by category in order to ensure they are properly disposed of or recycled.
At construction sites, the company is assisted by an acoustic specialist or installs a noise control wall (e.g., Cardinet car park).
Working hours are controlled to limit noise for local residents.
Mieux gérer les déchets
2000 m3 de déchets clients sont traités chaque année par le service propreté de Saemes. Le tri sélectif a été mis en place sur tous les parkings dès 2009 (poubelle papiers et poubelle autres déchets).
Les encombrants récupérés sur les parkings sont recyclés par filières (piles, batteries de voiture…). Concernant les batteries et les ordinateurs, leur destruction est tracée par un organisme extérieur. Les boulettes d’hydrocarbure sont stockées dans des barils hermétiques récupérés par un prestataire agréé.
Le traitement des eaux d’exhaure devient une priorité : ces eaux sont rejetées, lorsque cela est possible, dans la Seine plutôt que dans le réseau public d’assainissement. Sur certains parkings comme Ecole de Médecine, une partie des eaux d’exhaure est prélevée dans une citerne et réutilisée pour le nettoyage de celui-ci à la place de l’eau du réseau.
Enfin, le rejet de polluants nocifs par le service propreté est limité grâce à l’interdiction de certains produits chimiques (dont la Javel).
Better waste management
Some 2000 cubic metres of customer waste are processed every year by the Saemes cleaning department. A waste sorting system was installed in all car parks in 2009 (paper waste and other waste).
Bulky waste picked up from car parks is recycled based on type (device batteries, car batteries, etc.). With regards to batteries and computers, their disposal is managed by an outside organisation. Tar balls are stored in hermetically sealed barrels which are later picked up by a certified service provider.
Treatment of wastewater is a priority : when possible, this water is discharged into the Seine rather than the public sewage system. At some car parks, such as Ecole de Médecine, part of the wastewater is stored in a cistern and reused for cleaning rather than public water.
The discharge of hazardous pollutants by the cleaning department is reduced thanks to the ban of certain chemical products (e.g., bleach).
Bee hives above our car parks
Saemes also aims to contribute to broader environmental actions. For example, bee hives were installed on the terrace roof of the Firmin Gémier car park. In August 2015, a first harvest of 500 kg of honey was made.
