Owner approach of sustainability

COMPLETE and PERENNIAL RENOVATION of 4 PUBLIC HOUSING BUILDINGS (4 x 20): - INSULATION OF EXTERIOR WALLS, with installation of a CLADDING that does not require any particular maintenance - INSULATION OF "CELLARS" FLOORS - ROOF INSULATION - FRAMES REPLACEMENT , DV - REMOVAL OF THERMAL BRIDGES induced by the REMOVAL of "CONCRETE" BALCONIES and their REPLACEMENT by new METALLIC ELEMENTS disassociated from the STRUCTURE- INSTALLATION OF NEW INDIVIDUAL BOILERS "CONDENSING GAS" - IMPLEMENTATION OF MECHANICAL VENTILATIONS, type C (mechanical extraction) - ELECTRICAL COMPLIANCE and FIRE, with installation of LOW CONSUMPTION devices in common areas - COMPLIANCE "PEOPLE WITH REDUCED MOBILITY"

Architectural description

In addition to the desire to meet a significantly improved energy performance, the project wanted to give these public housing projects a new architectural identity. It is reflected in particular by an architecture symbolically inspired by the industrial past of the CITY of HERSTAL, presenting "structured" panels and balconies. The tones are intentionally sober but varied, each building being aesthetically differentiated (shade of cladding, colors of some glazed elements).
