Sustainable growth for L’Oréal
Challenge
Challenge
When L’Oréal decided to set up an advanced, new research center in Saint Ouen, Paris, it was imperative that the building itself encompassed the forward-thinking, responsible ethos of the company. Designed to facilitate the development and creation of new hair products for the future, the building needed to meet the highest standard of sustainable architecture, reflecting it through both its aesthetics and its performance.

Solution
Solution
Architect Frederic Tomat designed a light and airy structure that minimizes the impact of greenhouse gases through various measures, including an innovative self-watering green roof and terrace solution from BMI.
Through the use of our advanced BMI Siplast Waterproof system, we were able to create a durable solution that supports beautiful flora through a simple water-retention system. Nidaroof alveolar plates helped to manage the rate of water flow by providing a stabilizing substrate with an integrated honeycomb sheet that temporarily retains rainwater. For effective drainage of unused water, a separating geoface layer (Geoflow 44-1F) was installed between the highly resistant waterproofing membranes and Nidaroof panels. This simple system will help to sustain the green roof and ensures compliance with the strict Parisian water-dispersal regulations.
The vegetation was supplied as a pre-cultivated carpet created by an experienced landscape gardener. This beautiful natural covering was installed over the Waterproof solution on ribbed steel, anti-root, pre-vegetated watertight tanks.
Results
Opened in 2012, L’Oreal Saint-Ouen is now the company’s main research hub, leading development operations across the world. In addition to its aesthetic appeal, the green roof provides a reliable, low-maintenance solution that makes a huge contribution to the building’s overall environmental profile through its excellent thermal performance and ecological water management. Alongside the use of solar energy, it has contributed to the building’s HQE (Haute Qualité Environnementale) certification and has also seen it qualify for Outstanding Sustainable Building certification- a first for any Research Centre.
