Patriarche & Co completes office building in Lyon for Genzyme
Genzyme is a pioneer in medical biotechnology. It has set up its main premises in Lyon, in the Gerland district. A production unit, laboratories and offices are brought together behind a double skin that affirms the urban aspect of this project.
The landscaping design is integrated into the site plan, minimising waterproofing works and the planting of allergenic varieties. The vegetation is dense and diversified, with a large floral meadow planted at the heart of the plot.
Throughout the project design stage great attention was paid to research and studies into the environmental and health impacts of construction materials. Using lifecycle analyses and safety data sheets, we were able to choose healthy materials for people and the environment. The carpets, paints and timber used have 'label' certification. In the same way, deconstruction and recyclability, cleaning and maintenance were all key criteria in the choices made.
The thermal strategy is organised around a very efficient casing, consisting of a double glass skin, actively regulating the hygrothermal atmosphere inside the building summer and winter alike. An atrium distributes natural light inside the offices, saving on artificial lighting costs. Lastly, renewable energy is generated by photovoltaic panels, completing the system. During the design phase the building was modelled by thermal dynamic simulation using Trnsys software.
An in-depth environmental approach was used for the Genzyme - Lyon Gerland offices and laboratories project. It is the first French building certified LEED and 'NF Bâtiments Tertiaires – HQE®' (French standards for tertiary buildings, high environmental quality) to achieve the highest possible environmental profile, in the form of 13 'TP' (very efficient) targets and 1 'P' (efficient) target (target 14), in accordance with the August 2006 frame of reference.
