Treated HEQ® targets :


Target1: Harmonious relation of the buildings with their immediate environment
• Gathering of building around a main courtyard which echoed the type of farmhouses of Normandy.
• Homogeneity of surfaces treatments of the building by using of wood cladding and green roof.
• Excellent occupancy of the large and available parcel (21 600m²), planning the future extension of the factory.

 

Target 4 : Energy Management
• Installation of a heat Pump: diminution of the current cost of energy, good air circulation in the builging (constant temperature in every room).
• Canadian well complemented by a mechanical double flow ventilation system, for cooling and dehumidification in summer and for heating in winter.
• Access of natural lighting optimised by a provision of light from the sky in every room thanks to the lag between green roofs.

 

Target 5 : water managment
• Roof storm water treatment by green roof.
• Runoff water treatment by vegatal ditchs. The storage volume of the main ditch will be 216 m³, which corresponds to a volume of one hour of rain durinf 10 years.
