Energy-intensive building

Complete energy renovation of 4 x 20 PUBLIC HOUSING.

In addition to the installation of a new high performance envelope (WALLS, ROOFS, FRAMES) and the complete replacement of the systems (HEATING, SANITARY, VENTILATION and COMPLIANCE "PEOPLE WITH REDUCED MOBILITY" and ELECTRIC), each of the 4 buildings has registered in a search for a revaluation of the SOCIAL IDENTITY associated with PUBLIC HOUSING.

Building users opinion

The MASTER OF WORK carried out a satisfaction survey, which resulted in a globally high satisfaction rate.

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).

Reasons for participating in the competition(s)

BUILDINGS WITH LOW HEATING REQUIREMENTS thanks to the installation of a new insulating envelope (reduced by more than 50%), which are individually insured by means of HEATING PRODUCTION TECHNIQUES with high efficiency (NATURAL GAS, CONDENSATION system). An individualized MECHANICAL VENTILATION ensures in each dwelling the EXTRACTION of STALE AIR, ensuring de facto an optimal comfort for the residents.

This heavy energy renovation optimally combines high level of thermal performance with real ease of management and use by the occupants.
