In residential buildings and mixed-use buildings (offices and residential) that produce less than 1,100 liters of waste per week, the waste is collected by the local authorities. In office buildings and mixed-use buildings which produce more than 1,100 liters of waste per week, the waste is collected by private companies. In 2017, 29 office buildings have a waste collection agreement implemented by Gecina that includes a weighing requirement or an estimate depending on the number of bins removed, for a minimum of five channels (paper/cardboard, plastic, glass, and wood (in compliance with decree No. 2016-288 of March 10, 2016 respecting waste prevention and management adaptation and simplification). Depending on the waste generated on site, complementary sorting channels have been implemented to recycle cans, plastic cups, ink cartridges and WEEE. Gecina’s reporting on waste production and recovery will therefore cover more than 369,494 sq.m, i.e. 52% of offices portfolio.

Recycling of materials and products

Focus on eco-design The design and construction of low energy buildings (BBC – bâtiments basse consommation ) has brought to light the increase in requirements of construction materials needed to reduce energy use during operation (increase in thickness of insulation, more complex outside finishing carpentry, need for blinds, etc.). This change involves consideration of the overall impact of buildings throughout their life cycle in terms of both gray energy (1) and the production of hazardous waste, air and water pollution, and eutrophication (excess nitrogen, phosphorus, etc.) of environments (indicators determined by life cycle analysis - LCA). Since 2011, Gecina has performed LCA on all of the assets that it develops though internal project management to encourage low environmental impact solutions in its choice of materials and constructive measures. As a result, the impact on the protection of biodiversity, consumption of non-renewable natural resources, gray energy consumption and primarily CO 2 emissions is studied at various project phases: sketching for modeling and choice of the structure; ■ final design phase for the modeling and choice of ■ technical equipment; the project phase for modeling and choice of finishing ■ products.
