Embodied carbon
The strategies are focused on material reduction and the use of recyclable/sustainable input materials to lower the building's embodied carbon:
-
Material Reduction in Structure: The concrete slabs were optimized for thickness and reinforcement to minimize material use.
-
Weight-Reducing Elements: Recyclable weight reducing elements were incorporated into the concrete slabs, a proactive technique to minimize the overall volume of carbon-intensive concrete required.
-
Sustainable and Recyclable Finishes: Custom furniture uses sustainably sourced veneer from fast-growing European tree species. The flooring finish is an endlessly recyclable material, ensuring that the material can re-enter the circular economy at the end of its life.
Operational Emissions / Energy
Operational strategies are advanced and focus on high efficiency and user well-being, which were critical to achieving the BREEAM Outstanding score:
- Renewable Energy and HVAC: The design includes the integral use of renewable energy (specific type not stated, but integral use is confirmed) and advanced building systems, including heat pumps, for heating and cooling.
- Passive and Active Climate Control: Climate ceilings are installed throughout the offices, combined with carbon dioxide sensors to guarantee excellent thermal comfort and healthy indoor air quality.
- Daylight Optimization: At least 70% of the exterior wall surface consists of glass, combined with a design choice for high ceilings and abundant daylight. This minimizes the need for artificial lighting during the day, reducing electrical consumption.
- Energy Management: Energy consumption across all systems (lighting, cooling, heating) is meticulously measured for continuous optimization and minimized operating costs.
Service and maintenance emissions
The focus on maintenance is linked to efficiency and overall structural longevity:
-
Minimizing Maintenance Costs: The overall design aimed to minimize operating and maintenance costs, suggesting the selection of durable and long-lasting materials and systems.
-
Integrated System Longevity: The advanced building management system that controls the heat pumps and climate ceilings ensures the equipment runs optimally, which inherently extends the service life of the mechanical systems.
-
Green Infrastructure: The green façade on the new parking building connects seamlessly with the park, providing insulation and protecting the building envelope, thus contributing to long-term resilience and reduced maintenance needs over time.
Afterlife
Flexibility is central to the design and is framed as an "intelligent shell" built to evolve with changing user and societal needs.
- Optimal Flexibility: The office spaces are entirely free of structural elements apart from the load-bearing columns and the central core (containing elevators, stairs, and technical shafts).
- Modular Layout: This arrangement allows office levels to be optimally divided, combined, and split again in the future into flexible entities ranging from 200 to 550 square meters to meet changing market demands.
- Structural Alignment: The column grid is designed to accommodate both the parking function (two cars fit between two columns) and the office function (desks) seamlessly, demonstrating inherent structural flexibility.
The design approach emphasizes both design for disassembly and material circularity:
-
Recyclable Elements: The flooring material is specified as endlessly recyclable.
-
Design for Disassembly: The flexible layout, which uses the main structural columns as the only fixed elements in the office space, implies that non-structural partition walls and internal fit-outs can be easily removed and replaced for future program changes, aiding disassembly.
-
Concrete Reduction: The incorporation of recyclable weight reducing elements into the concrete slabs suggests that these specific components can be recovered or recycled at the building's end of life.
