Primary energy need
(Calculation method : RT 2012 )
The operation concerns the design of a new heart of the City, in connection with the existing Town Hall, within a site in full requalification (subdivisions in the course of realization, project of modification of the road network, rehabilitation of the 'old train station). This operation offers the city of Pannes both shops and services as well as spaces for care, work and relaxation. Local companies have been favored (95% of the work) and the buildings constructed are energy efficient.
The organization of buildings and flows takes into account the needs and uses of residents and users. The treatment of outdoor spaces plans to develop quality green spaces, punctuated by forecourts.
A building made from local biosourced materials
Within this urban renewal project, the central building of the Center Bourge is built according to the following construction methods:
- Wooden frame walls with insulation distributed in straw;
- Insulating joist-slab floors;
- Wooden floor structure;
- Traditional framework;
- Insulation in blown cellulose wadding.
The straw comes from crops in the town of Pannes. It was stored by the city on its territory to then be installed in the wooden frame walls by the UTB carpenter in Villemandeur (<8 km from the construction site). The prefabricated elements were then assembled on site.

Timber frame walls, straw filling
Utb has specialized for several years in the manufacture and installation of timber frame walls.
Indeed, wood has become a very good alternative to concrete, it has many thermal, environmental and aesthetic advantages.
Thus, buildings made of wooden frames guarantee natural and efficient insulation for its users.
At the request of the City of Pannes, which wanted to favor local materials, the walls are insulated with local straw.
