Sustainability Report
Embodied carbon
The project prioritises low-carbon construction through extensive use of timber in the facades and internal elements. Prefabricated timber frame modules reduce waste and transport emissions, while the timber cladding is thermally modified rather than chemically treated, improving durability with minimal environmental impact. FSC-certified wood ensures responsible sourcing. Additional reductions come from:
- Laminated timber beams in the atrium.
- Climate-positive flooring (≤ 5 kg CO₂/m² embodied).
- A compact building footprint that consolidates multiple functions into a smaller volume than before.
Operational Emissions / Energy
The building performs as energy-neutral in use. It is designed for very low operational carbon, supported by the following:
- Energy label A+++++
- Energy demand: 65 kWh/m², fully covered by on-site renewables.
- Heating and cooling via a geothermal system with heat pumps.
- CO2-controlled balanced ventilation with heat recovery.
- Smart-controlled, energy-efficient pumps, fans, and LED lighting.
- Full rooftop PV array providing all required electricity.
- Optimal daylight: atrium, courtyards, and tall windows reduce artificial lighting demand.
Service and maintenance emissions
Building systems were selected for long service intervals and energy-efficient operation. The facade and envelope are designed for low-maintenance:
- Thermally modified timber cladding requires minimal treatment.
- Durable modular facade panels allow isolated repair rather than full replacement.
- High-quality Schüco aluminium frames reduce long-term maintenance cycles.
- Simple access to terraces and modules enables efficient inspection and repair.
Afterlife
Adaptive reuse was an explicit consideration.
- The main structure is concrete with minimal columns, allowing large, open floorplates that can shift to new uses without structural change.
- The facade uses a uniform module size, enabling window relocation, addition, or replacement if the internal programme changes.
- Interior planning accommodates functional change for care functions, offices, or other support programs, ensuring long-term relevance.
The project incorporates several components that can enter a circular cycle:
- Prefabricated timber facade panels can be individually removed, repaired, or replaced.
- Standardised aluminium and glass window modules facilitate reuse and reinstallation.
- Thermowood cladding can be dismantled and reused due to mechanical fixing and stable material properties.
- Modular detailing ensures the facade can be adapted without demolition.
