With its 6 700 inhabitants, Seyssins is part of the Grenoble urban agglomeration (the METRO). The City is already committed to the development of a more sustainable energy policy by means of different initiatives.
Seyssins joined the Display ® Campaign in September 2005. The first step was to raise awareness internally in order to change the mind set within the administration thus facilitating a broader initiative focussed on reducing the consumption of energy. With this approach in mind the engineering department of Seyssins offered to control the temperature of the public buildings in order to achieve savings.
This initiative started after they realised that there is often a difference between the capacity of the boilers and the real needs of the buildings. The heating installations are indeed often oversized, especially when over the years there has been improvements in the insulation of the building

When it is necessary to change the boiler, often in the case of an emergency, the new capacity installed is still not adapted to the real heating requirements of the building due to a lack of knowledge. Therefore, the engineering department of Seyssins recommends preventive energy audits in order to know the heating requirement of the building and to envisage the replacement by a boiler of adapted capacity when that is necessary.
This step avoids paying more for oversized equipment throughout the lifespan of the boiler.

Currently, two schools - Priou and the Louis Armand primary schools – had their boilers adapted to the real heating requirements of the buildings. Indeed, the boilers dated back to the construction of the building and the improvements on the envelope revealed that the boilers were oversized. These changes made it possible to achieve substantial savings and this success will lead to other replacements of the same type in other municipal buildings.
