Purpose of the project
The refurbishment of 55 rue Amsterdam in the 8th arrondissement of Paris, an office building of 12,100 sqm built in 1929, is an illustration of the quest for excellence and innovation developed by Gecina in each of the company’s Sustainable Building themes and eco design.
The main idea is to transform this old building in the center of Paris into a multi-labelled office complex at the forefront of innovation in terms of both environmental aspects and uses.
The building will become operational by 2017.
For each Sustainable Building theme, specific targeted actions are carried out:
- Energy efficiency and renewable energies: Reduction of energy use by 45% through high efficiency thermal insulation and high performance HVAC equipment.
- Certification targeted: HQE® Exceptional, BREEAM® Outstanding, LEED® Platinum, Effinergie Renovation Label, WELL Label and BiodiverCity Label
- Health: Implementation of low impact construction materials with the most highly restrictive labels (GreenGuard, Ange Bleu and Cygne blanc)
- Well-being and Comfort : Optimal management of ambient comfort (real time monitoring of energy use with the Hypervision® tool, comfort level with the Fireflies® sensors for temperature control, air quality and noise control)
- Accessibility: Compliance with applicable regulations
- Connectivity: Alternative transportation means promoted by providing assigned parking places for electric vehicles with recharging facilities (10% of total), ride-sharing vehicles (3%), bicycle storage room of 50 sqm
- Security: compliance with regulation
- Climate Change: Connection to urban heat and cold networks, partially powered by renewable energy
- Non renewable raw materials: Use of bio-based and locally produced materials: use of 6,000 sqm of wood based insulation inside the building, with 10% of products from a local producer (located within 800 km)
- Recycling and waste management: Installation of structures adapted for sorting with six waste sorting lines available
- Biodiversity: Buildings with high vegetation concentration: green roofs and courtyards (a 300% improvement in BAF) - 20 cm substrate and 56 different species integrated
- Water: Rain water retention facilities and reuse of gray water for toilets and plant watering.
Current certification and labels:
- BiodiverCity Label was accorded in November 2014. Comprising four areas (commitment, project, ecological potential and amenities), the label attests to the compliance of the real estate project with an ecologic level of quality. It provides assurance of a project’s compliance with requirements specified in a reference source.
- Well label application in progress : Gecina is the first French company to apply and to be eligible for this label. The Well label contains seven themes, Air, Water, Nutrition, Light, Fitness, Comfort and Spirit and promotes a holistic approach based on the twelve health and well-being domains including concentration, energy, physiology, rest and regeneration, stress and mood management and others. It breaks down into 85 criteria classified in the three categories of pre-requisites, optimization areas and optional optimization areas.
Anticipated quantitative results:
- Energy efficiency: the target is set to an energy saving of -45%, which represents a consumption of about 274 kWh (primary energy)/sqm/year
- Climate change and GHG emission: the target is to reach an overall emission of 8.9 Kg Eq C02/sqm/year
- Water: the target is to reach an overall water use of 0.54 m3/sqm/year as well as accommodation of 25% of the building’s requirement of non-potable sanitary facilities water and 100% of the watering requirements
Other anticipated results are defined by the targets described in the “Approach” section.
“Gecina continues to develop a portfolio of responsible, efficient, new-generation buildings, fully integrated into the city and their districts on all levels, supporting the wellbeing and productivity of user customers”
