Architectural description

Intentions, starting point of the urban and architectural project:

o The main objective is to create a specific place at the Perex 4.0 center, in   with Perex 1.0, in order to create a coherent whole, through a qualitative landscape and urban planning approach .

o The implementation of the new administrative building is defined in such a way as to make it visible and accessible from the public space, while taking full advantage of the potential of the site, in order to reinforce the existing landscape qualities and to respect the qualities of the related building. The main lines of force of the main roads and highways that make up the site are taken into account as part of this reflection.

o The various constraints related to the geographical location of the place, the specific program, the orientation, the visual perspectives or the goal of high environmental quality, are all opportunities to optimize the project and improve the immediate environment.

o The singularity of the program, located at the motorway junction of Wallonia, at the gates of its capital.

o The building is designed taking into account exterior traffic , accessibility and external mobility.

o Environmental and sustainability specifications are integrated at every stage of the design, from the definition of building orientation to details of construction, choice of materials, facilities and technical equipment.

Smart Building

BMS :

Based on the meters and sensors installed in the buildings, a program concerning energy monitoring of buildings will be proposed thereafter allowing to adjust the energy consumption during the first phases of exploitation (Commissioning) and to avoid by following all drifts of these consumptions (energy monitoring). The tools proposed for the verification of the energy performance of the project will therefore be as follows:

- Commissioning: Mission of assistance and advice for the regulation of the regulation parameters related to the energy systems present in the buildings, in operating conditions during the first year. This mission will be based on a monthly visit and a visit report including the energy balance of buildings and the adaptations and / or remarks to improve the regulation of the various systems. In addition, at the end of a full year of operation, an assessment of the real energy performance of buildings will be carried out, allowing a comparison of actual performance with those planned for design.

- Energy monitoring - M & V according to IPMVP: An energy monitoring according to the IPMVP protocol can be proposed thereafter. It will be based on a sensor / meter network placed within the building, and a computer platform for processing and analyzing data based on thermal simulations of the building. The objective is to provide a detailed, continuous and predictive analysis of the operation of the building (consumptions and comfort obtained). A service based on the skills of the design office will be proposed to advise and assist the client continuously based on the analyzes performed.

Urban environment

Homogeneity: by the perfect coherence of tones (white / gray), the play of simplified volumetrics and the assertion of the tower as connecting element, the fusion is perfect.

This perception is reinforced by the complete covering of the perex 1. 0 of a coating on insulation and its existing zinc cover.

The new center comes to take support on the ground, taking advantage of the differences of level to integrate the ground garden in a base.

On this base, the project comes to take support. The different slides between them to make the most of the resources they need.

Central place : motorway crossroads of Wallonia, the site has an important symbolism in the notion of control. We wanted to highlight this symbiosis between the site and the program.

Signal: The new control center proudly displays its central status.

Parking: We favored concentration rather than spreading, in order to optimize the landscape integration and the quality of the distributions.

1. A new 50-space car park (of which 36 reserved for the police) is created on the left of the project,

2. the current car park (in ground garden) and along the road is repacked in 55 locations.

3. The existing 15-seater pocket, located before the site, is maintained.

A total of 120 places (including 3 PRMs, in the immediate vicinity of the entrance).
