  • External insulation with double-glazed windows.
  • Eco-materials on the roof made from recycled tires.
  • Water recovery system integration.
  • Airtightness target: n50 < 1.1.
Performance Evaluation
  • Wood boiler with hydro-ejector technology.
  • Dual-flow AHU with heat recovery >85%.
  • CO₂ controllers in each classroom.
Diagnostic Testing
  • Blower-door testing for airtightness verification.
  • Thermal imaging for insulation quality control.
  • Ventilation performance and CO₂ sensor calibration.
Maintenance Review
  • Maintenance protocols for wood boiler and ventilation systems.
  • Operator training on CO₂ control optimization.
  • Seasonal inspections for energy systems.
System Optimization
  • Balancing of ventilation rates for comfort and efficiency.
  • Optimization of wood boiler operation for seasonal load.
  • Integration of water recovery with building management.
Efficiency Improvement
  • Energy and water monitoring for real-time performance tracking.
  • Energy consumption target: < 50 kWhep/m²·year.
  • Continuous improvement through annual recommissioning.

Result: A state-of-the-art educational facility achieving exceptional energy efficiency and indoor air quality, leveraging eco-materials and renewable heating to meet ultra-low consumption goals.
