Two 'learning stores' with the best equipment in energy saving were completed in 2011. The Quimper store in Brittany had the lowest consumption, with energy-efficiency techniques such as skylights across the whole store, rainwater used in toilets, solar water heating and 330m2 of photovoltaic panels. It also has sustainability features such as a green roof, night cooling and an orchard with bees.
The Lormont store, in Bordeaux, achieved a grade B, which is high on the energy-efficiency scale. The energy-efficiency techniques included a larger roof and wall insulation, skylights on 8% of the roof space and low-consumption lighting tubes called T5 Eco.
In-store energy reduction
In 2011, Castorama France achieved a 16% reduction in energy intensity from a 2010 baseline. Every store had a reduction target, ranging from 5% to 15%, on electricity consumption per square metre. All maintenance managers can check the hourly curve of energy consumption for electricity or gas and compare it with the previous year or with other stores.
In 2011, best practice guidance on energy-saving and performance spreadsheets were sent to every store manager and maintenance manager. Castorama France also featured a number of articles on energy-saver champions in the Planetcasto newsletter, and ran several spots on CastoTV, focusing on energy saving. The management team has been regularly informed of progress and impact on individual store, regional and national energy use and costs.
Energy saving in the home
Castorama has a number of tools aimed at helping customers save energy in the home. It has built an online application where customers can develop their own insulation plans to save energy. Castorama also has a dedicated webpage for its eco product range, known as 'la maison eco'.
It has created a series of videos called 'weekend castoche', offering detailed DIY demonstrations which will help customers to create better homes; several of the videos are about installing insulation.
