Broeklin: a circular working and shopping district for the future<\/h1>\t\t\t\t<\/div>\n\t\t\t\n\t\t\t\t\t\t\t
\n\t\t\t\t\t\t\t\t\t\t

Broeklin is an innovative, circular working and shopping district located on the northern edge of Brussels. The development brings together work, retail and leisure, supporting both production and consumption with the short supply chain as a guiding principle. Residual streams are given a second life: what is waste for one function can become a valuable raw material for another. With urban agriculture integrated on site, Broeklin is designed as a sustainable and efficient closed loop. Sweco is the engineering partner for technical installations, structural design and infrastructure, and also acts as consultant for acoustics, fire safety and sustainability.<\/p>\n<\/p>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\n \t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n

Flexible architecture embedded in the landscape<\/h2>\n

The site was designed by ORG Urbanism & Architecture and Jaspers\u2011Eyers, with landscape design by Bureau Bas Smets. Six large, contemporary halls form a coherent whole, together covering 150,000 m\u00b2. They accommodate thousands of employees and visitors and support a broad mix of uses, ranging from retail with on\u2011site production or finishing to food and beverage, leisure, culture and office spaces.<\/p>\n

The design actively brings the landscape into the buildings. Architecture and environment merge seamlessly, resulting in nearly half of the total site area being green.<\/p>\n

Sustainability as a core principle<\/h2>\n

From the outset, the design team adopted an integrated sustainability approach in line with Sweco\u2019s design principles. Broeklin is targeting multiple certifications (BREEAM, WELL, EU Taxonomy and LCBi), not as an end in itself, but as a means to realise its ambitions and maximise overall sustainability performance.<\/p>\n

The sustainability strategy is structured around four key pillars:\u00a0Energy, Water, Materials, and People & Environment.<\/p>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n<\/section>\n\n\n

  1. Reducing demand<\/strong><\/li>\n<\/ol>\n

    Advanced insulation significantly limits heat loss and allows energy to be retained for longer. Sweco\u2019s engineers designed highly energy\u2011efficient systems for heating, cooling, ventilation and lighting. Natural ventilation principles further reduce reliance on mechanical installations.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

    1. Maximising renewable energy<\/strong><\/li>\n<\/ol>\n

      The design combines several concepts for efficient heating and cooling, including Aquifer Thermal Energy Storage (ATES) and advanced cooling tower technology. Roof surfaces are optimally equipped with photovoltaic panels. As a result, Broeklin\u2019s energy performance is 36% better than the EPB standard, well above statutory requirements.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

      1. System integration<\/strong><\/li>\n<\/ol>\n

        Energy exchange between different concessions and halls is enabled through a site\u2011wide energy network, preventing peak loads and oversizing. Thermal buffers and batteries temporarily store surpluses, allowing energy to be deployed intelligently at a later stage and enabling effective peak shaving. This integrated approach ensures that all systems operate as one coherent whole rather than as isolated technologies.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n

        1. Reducing consumption<\/strong><\/li>\n<\/ol>\n

          Water efficiency is the first step. Water\u2011saving toilets and showerheads reduce flow rates for sanitary use, in line with BREEAM and EU Taxonomy requirements. Electronically self\u2011closing taps prevent unnecessary waste, while a leak detection system improves robustness in both operation and management. The landscape design further limits irrigation needs.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

          1. Maximising reuse of rainwater and groundwater<\/strong><\/li>\n<\/ol>\n

            By carefully sizing and positioning rainwater tanks and buffers, applications such as toilet flushing can be supplied entirely with recovered water. For broader reuse applications, including irrigation and cooling towers, up to 77% of demand can be met with low\u2011quality water, significantly reducing reliance on mains supply.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

            1. Drainage and buffering<\/strong><\/li>\n<\/ol>\n

              Permeable surfaces account for 26% of the site, combined with buffering systems that delay drainage and collect water during heavy rainfall. This approach ensures no additional burden on the sewer network compared to the pre\u2011redevelopment situation.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n

              1. The R\u2011ladder<\/strong><\/li>\n<\/ol>\n

                Broeklin is based on the principles of the R\u2011ladder, with a strong emphasis on reduction through optimisation. Refined structural calculations prevent over\u2011dimensioning, vulnerable building elements are protected, and durable, high\u2011quality materials are selected. By deliberately leaving some internal concrete structures exposed, unnecessary finishes such as paint or suspended ceilings are avoided.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

                1. Circular economy<\/strong><\/li>\n<\/ol>\n

                  Secondary materials are used wherever possible, and reuse is maximised. Where reuse is not feasible, materials with recycled content are prioritised, preferably from post\u2011consumer sources. For concrete, glass, aluminium joinery, insulation and metals, the proportion of primary raw materials is deliberately limited.<\/p>\n

                  Broeklin aims to set a national benchmark for concrete, with a target of 30% recycled content. This corresponds to a volume of recycled aggregate equivalent to Belgium\u2019s total use in 2025. Concrete mixes are precisely optimised to meet exposure and strength requirements and are produced close to the site to minimise transport impacts.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

                  1. A holistic approach to health<\/strong><\/li>\n<\/ol>\n

                    Health is understood in its broadest sense, encompassing physical, mental and social well\u2011being. As people spend most of their time indoors, buildings should do more than provide shelter; they should actively support user comfort and health. When designing the indoor climate, Sweco\u2019s engineers paid close attention to temperature, humidity, air movement and air quality.<\/p>\n

                    Abundant natural daylight, validated through daylight simulations, enhances visual comfort.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

                      Universal accessibility is embedded in the design through inclusive choices such as ramps and clear signage. Thoughtful wayfinding ensures the site is intuitive and easy to navigate for all users.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

                        The former brownfield site has been transformed into a rich ecological landscape with strategically positioned green zones. Sweco\u2019s infrastructure experts supported landscape architect Bas Smets in the technical development and integration of the landscape design.<\/p>\n

                        The roof of Hall 4 is seeded with grasses, while fa\u00e7ades incorporate greenery. Valley landscapes with pioneer and climate\u2011resilient trees connect public areas, complemented by larger forest zones focusing on native species. Water landscapes, including ponds and wadis, enhance biodiversity through water\u2011loving plants. Indoors, biophilic design elements such as planters, shrubs and houseplants further strengthen the connection with nature.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n

                        Safe shopping and working<\/h2>\n

                        Fire safety is a defining aspect of the design, given the scale and multifunctional character of the project. Sweco\u2019s fire safety consultants assessed the development using a performance\u2011based approach, examining where the design deviates from prescriptive fire standards and evaluating the implications for user safety, structural integrity and environmental impact.<\/p>\n

                        Their assessment covered fire detection, firefighting systems (including sprinklers), smoke and heat extraction, evacuation strategies, fire resistance, compartmentation and accessibility for emergency services. Using advanced simulations, evacuation scenarios were analysed in terms of ventilation, temperature and visibility. The design comfortably meets the required safety margins.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

                        Acoustic comfort in a multifunctional environment<\/h2>\n

                        Fa\u00e7ade insulation limits external noise intrusion, which is particularly important given the site\u2019s proximity to major traffic routes and a nearby airport. In buildings accommodating events or recording studios, box\u2011in\u2011box constructions are used to minimise sound transmission and prevent disturbance to other users or the surrounding community.<\/p>\n

                        Throughout the rest of the development, precise acoustic separation is provided between different functions. High\u2011performance floating floors and sound\u2011insulating walls prevent noise transfer between offices, meeting rooms and leisure spaces. Finally, the careful design of voice alarm systems ensures clear and intelligible communication during emergencies, adding an essential layer of safety to the acoustic strategy.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n
