How green walls make a difference in ‘t Centrum

‘t Centrum will have green walls throughout. But why do green walls make such a difference? And how do they influence circularity?

The greening of façades, roofs and the immediate surroundings of buildings is just one of many ways to increase circularity. Green spaces provide buildings with ecosystem services with a circular effect. What’s more, nature provides these services for free.

“’t Centrum will have two green walls that have their own circular qualities. These walls do so much more than ordinary walls. The green wall inside the building will also influence the building’s climate. Moreover, the exact effect will be accurately measured. The walls will be irrigated with rainwater that we collect on or around the building”, Teun Depreeuw, the CEO of Muurtuin, adds.

Green wall

The green wall outside acts as a building envelope for part of the building, with the green space providing insulation as an added service. This outdoor green wall will be supplied with greywater (TOTAL VALUE WALL©). Here the adapted planting is used to treat the greywater, as part of a vertical water treatment facility. The greywater also provides nutrients for the plants.

Maintenance

Ordinarily vertical gardens require maintenance three times a year, in the form of replanting, pruning and fertilising. The classic indoor vertical garden also needs additional light to ensure that the wall’s indoor plants remain green.

The conventional outside vertical garden, which is supplied with grey water, is planted with adapted plants. The set-up was based on the results of the previously executed TOTAL VALUE WALL© test, giving rise to a version 2.3 as a result in ’t Centrum.

  • The most circular office building of the Low Countries can be found at Kamp C in Belgium

    Kamp C, the living lab of the Province of Antwerp for sustainability and innovation in the construction industry, and a previously selected consortium of seven companies have recently completed ‘t Centrum in Westerlo (Belgium). This is the first completely circular office building in Flanders. The three-storey building has a total surface area of 2,400 m2. The building’s high level of circularity is remarkable. It has been entirely constructed from reusable materials and can thus be completely disassembled and rebuilt elsewhere. The builders used innovative materials, applications, techniques and new business models throughout.

  • Magnesium oxide insulated panels for ‘t Centrum

    The walls of ‘t Centrum are clad with vapour-permeable, magnesium oxide insulated panels. Magnesium oxide has several circular properties and is fire-resistant. Bart D’Haese, an expert in Healthy Houses at EXIE NV, and contractor Joeri Beneens explain the reasons behind this choice.

  • Cellular glass for the circular roof of ‘t Centrum

    Cellular glass insulation was chosen for the roof terrace of 't Centrum, a circular office building in Westerlo (Belgium). The office building has been built in such a way that it can be dismantled and rebuilt elsewhere using the existing materials. The choice of cellular glass insulation, a material that is produced by FOAMGLAS ®, was made based on compressive strength to bear the load of the decking. Below we list four reasons why cellular glass is a good choice for a circular roof.
