Challenge
Solutions & Tech Applied
Request from the city Mayor: HEQ design, renewable energy, and maximum comfort. Photovoltaic production: 46.60 kWh/m²/year, and CO2 emissions: 7 kgeq CO2/(m²/year)
The main features and benefits of the proposed solution are:
- Variable flow installation and installation optimisation
- No performance loss
- Uniformity of temperatures
- Control of residual air speed in the desired area
- No recovery network, thus fewer load losses for fans, lower maintenance costs, smaller, no condensation, and no heat insulation
- Strong Delta T, thus flow reduction
- Ultra-fast warm-up
- Setting of desired comfort level through air speed regulation according to functional logic
- Heavy-duty free-cooling
- Natural ventilation mid-season and night for exploiting the thermal inertia of the low slab with sanitary vacuum.
Key Tech Features
BMS, free-cooling, including motorised opening control system
