Sustainability Report

The project achieved a significant reduction in operational emissions through a holistic energy strategy that surpassed the national WT2021 standards by 30% (EP of 42.13 kWh/m²a vs. the limit of 60 kWh/m²a). The primary design choice was the total decarbonization of the heating system for this 280 m² facility: replacing an obsolete gas-based infrastructure with a high-efficiency air-source heat pump cascade powered by an on-site Photovoltaic (PV) array (Q ≈ 13,213 kWh/year).

By achieving high thermal inertia through a high-performance building envelope and repurposing existing underground infrastructure for rainwater harvesting, the operational carbon footprint was minimized to 18.43 kg CO_2/m²/year. This marks a transformative shift from a carbon-heavy 1980s facility to a low-emission, energy-efficient modern landmark.

The reduction in service and maintenance emissions was achieved through a strategic selection of high-durability, low-maintenance materials and simplified technical systems. By opting for a ceramic and aluminium facade and roofing, the project eliminates the need for frequent chemical cleaning, painting, or surface treatments required by traditional plasters.

On the technical side, the replacement of complex, high-maintenance fossil fuel boilers with a modern air-source heat pump cascade significantly lowers the frequency and intensity of technical service interventions. These units, combined with the integrated PV system, operate with minimal mechanical wear. Furthermore, the decision to repurpose existing underground infrastructure (the rainwater tank) reduced the carbon-intensive transport of new construction materials to the site and simplified long-term site irrigation maintenance, resulting in a highly resilient and "service-light" architectural ecosystem.
