With a total net floor area of 23,300 m², Green Office® Meudon is the first large scale positive energy office building in France. Designed by Bouygues Immobilier and subsequently acquired by Scor, it has hosted 1,250 Steria France employees since July 2011. The building is operated and maintained by Exprimm under the terms of an Energy Performance Contract (EPC), which provides guarantees on energy consumption and production according to pre-set conditions of use.
The data collected by Si@go, a software application specifically developed by Bouygues Immobilier and Steria, shows that annual generation and consumption exceeds forecasts:
- The differential between energy production and consumption stands at 9% vs. a theoretical forecast of 3%.
- Annual energy generation came to 76.9 kWh/m² vs. 64 kWh/m² projected at the outset. Production by the cogeneration plant trended in line with consumption whereas power contributed by the photovoltaic panels was 12% higher than theoretical calculations.
- All-purpose energy consumption* stood at 70.8 KWh/m²annually compared with theoretical consumption of 62 KWh/m². Excluding heating, which overran significantly, consumption for other purposes was in line with forecasts, or lower than estimated for some items.
* consumption from regulatory usages (heating, air-conditioning, ventilation, lighting, auxiliary equipment and circulating fans) as well as from office appliances, lifts, car parks, etc.
