Embodied carbon
Efficient
Embodied carbon overview
- All walls and floors are prefabricated and constructed from timber. Steel is used where required, limited to elements that can be flexibly incorporated.
- The contractor prefabricated all timber walls and floors in-house. The facade builder, Bouwmag, prefabricated the glass block elements using plastic reinforcement and insulating concrete. The specified glass blocks are double-walled, energy-saving units supplied by Seves Glassblock (Clear 1919/8 Clearview).
Operational Emissions / Energy
Low Carbon
Operational emissions overview
- The project complies with Centrumeiland’s permit requirements, which require demonstration — using calculations — that the building is rainproof prior to submission.
- An MPR calculation and a BENG calculation were carried out in accordance with Building Decree regulations. The dwelling achieves an energy label of A+++, with fossil energy use of 26.31 kWh/m² per year (6.17 kgCO2/m² per year) and a renewable energy share of 76.7 percent.
- Heating and hot water are provided via a heat pump. A balanced ventilation system with heat recovery is installed, alongside photovoltaic panels. The dwelling includes a mechanical cooling system and is not connected to a gas network.
- The heat demand is 56.54 kWh/m² per year, with a low risk of overheating during summer months.
Service and maintenance emissions
Recycled aluminium window frames are used, offering a long-lasting and maintenance-free solution.
Afterlife
Adaptive Reuse and Flexible Design Considerations
Light House is conceived as a lightweight structural system, comprising a steel frame infilled with prefabricated timber elements. This modular approach supports flexibility and ease of disassembly over time.
