In order to ensure a harmonious connection between a dense residential area of Laeken and the industrial area of the Port of Brussels, a brownfield site was requalified. This made it possible to develop a brand new neighborhood integrating housing, modern equipment, activities for children and businesses, integrated in a green framework that meets the status of sustainable neighborhood of the most modern and the most attentive to the environment.
This was directly rewarded by the interest of potential occupants of all types and sectors, concretizing the modernization of a neighborhood that immediately found his own.

Owner approach of sustainability
The project aims to reduce city water consumption through rainwater harvesting and greywater recycling. The water management systems are integrated into the landscaping of the site, which brings at the same time an omnipresent biodiversity: green and storing roofs, green facades, storm basins, bio-purification and infiltration beds, permeable materials ...
The district is served by a district heating network, from a centralized high-performance boiler room. The production of energy is completed by the installation of photovoltaic panels on the roofs.
These power generation facilities are managed by a third-party investor who guarantees a lower cost of consumption than the official statistical cost.
A system for sorting and collecting household waste by underground containers is installed in the public space.
In order to raise awareness and empower new residents, all have signed a sustainable neighborhood charter outlining the ideal conduct to ensure the smooth functioning of sustainability aspects.
The project followed an assessment path for a BREEAM communities certification. According to preliminary results, to be confirmed by BREEAM, the score would exceed 93%, which would make Tivoli GreenCity the most sustainable district in the world!
The architectural design has been entrusted to several architectural offices and the buildings each have a distinct personality that allows their inhabitants to identify themselves.
In order to integrate the existing heritage, the old building Belgacom is renovated and plays the role of anchoring the new district in the old.
Transit traffic and access to underground car parks are reported on the suburban streets, while the new inner streets are designed for soft mobility and priority for pedestrians and green amenities. Streets follow a long S-shaped path, which reduces speed while providing a greener overall view through the non-linear alignment of trees on the sidewalk.
663 bicycle parking spaces, including 583 sheltered indoor parking spaces and 80 on-street parking spaces, are located in the immediate vicinity of building access.
The accommodations are compact and through. The rooms of day, stay, kitchen, terrace, are in direct functional relation and the orientation of the housings ensures the best sunshine of the living spaces. Building circulation cores make the most of natural light, which reduces the demand for electricity for common areas.

Treatment and recovery of greywater to feed the toilet

Management / Others
The water in the shower, sink, bath, washing machine and kitchen is called gray water.
It is essentially all domestic wastewater, with the exception of toilet water (= black water).
These gray waters are therefore less polluted and can be perfectly cleaned and then used as a flush or reuse in the garden.
The greywater unit is based on the principle of biological purification. The fat separator is the first step in purifying the system. Because of the internal partitions, the water is forced to pass through the compartment in a winding movement, so that the fats are trapped. The water is then aerated in the second purification stage. Microorganisms break down organic components in wastewater. Bioballs provide additional adhesion surface and promote optimal purification. The water is then cleared of its smells and colors. The third compartment contains activated carbon. Activated carbon is a form of carbon that has been treated to have as large a reaction area as possible per unit volume. In the fourth and final purification step, the water is disinfected using UV light.
After purification, the water must be collected in one day. This daily stock must be plastic and its volume depends on the project. It is important that the purified water is not stored longer than necessary.
The gray water treatment unit comprises a large tank, compartmentalized inside during the purification steps described above.
