Designed by architect Romain Schmitz and realized by POST Luxembourg, the ‘Mercier’ office building is located in the Gare district where it occupies a surface area of 60 x 60 m around the Rue de Reims. The development owes its name to the company Mercier, who previously operated a champagne factory on the site.
The building comprises two basement and six floors above. The ground floor and first floor are partially accessible to the public with post office counters, as well as commercial and meeting areas in the large central atrium. The remaining four floors are reserved for offices and can be flexibly converted into several units. These upper floors are organized around an atrium with a canopy spanning 24.5 m, thus providing an abundance of natural light.
The structure of the building consists of reinforced concrete with massive slabs on pillars. These so-called ‘active slabs’ include an integrated pipe system that allows the concrete mass to be used for the storage and exchange of heat energy. In order to optimize the abundance of natural light, these slabs are made of a very light coloured concrete.
All of the architectural and technical approaches and specifications were implemented in a spirit of durability and comfort of use. Sanity fittings were provided by Villeroy & Boch throughout. These include toilet fittings from the Subway Direct Flush C+ and O.novo Vita WWC lines, Subways urinals with ProDetect 2 technology, as well as hand basins from the Loop & Friends as well as O.novo Aussgussbecken collections. The buildings developers explain these fitting were selected due to their quality and performance, but also on the basis of solid brand reputation.
The new "Mercier" building of the POST will be certified according to the criteria of sustainable building DGNB which includes the themes of noise insulation and acoustic comfort. INCA conducts the acoustic studies required during the design phase in order to respect the thresholds imposed, assists the prime contractor in the field of acoustics during the submission of the works and will have a monitoring mission during the implementation phase in particular for find defects in implementation such as sound bridges. Apart from this acoustic component of the building INCA regularly takes measurements of site noise to document the requirements for classified establishments.
