Sport New Construction – Energy

Sector: Sport Year: 2015 City: Liévin, France Gross Floor Area (GFA): 1,080 sqm Total Cost: €2.2 million Scope of the Mission: Energy Project Management (~2.5 years: Program, Design, Construction, Commissioning, Occupancy, Maintenance)

New construction of a sports facility delivered with an HQE approach and RT212 compliance. High-performance envelope with external insulation and double-glazed windows, airtightness target Q4 < 1.7 m³/m²·h, gas condensing boiler, dual-flow AHU with >80% heat recovery, single-flow unit with CO₂ control for the gymnasium, and an energy & water monitoring system to sustain performance in use.

Detailed Assessment
  • Project type: new construction with HQE and RT212 targets.
  • Envelope: external insulation and double-glazed windows.
  • Airtightness design objective: Q4 < 1.7 m³/m²·h.
Performance Evaluation
  • Defined KPI baselines for energy and water use.
  • Verified heat recovery efficiency >80% on dual-flow AHU.
  • Assessed seasonal efficiency of the condensing boiler.
Diagnostic Testing
  • Functional tests: AHUs, boiler plant, and CO₂-controlled single-flow unit.
  • Air and water balancing; controls sequence verification.
  • Airtightness test protocol and results review.
Maintenance Review
  • Preventive maintenance plan and calibration routines.
  • Operator training for seasonal changeover and alarm handling.
  • Asset register and critical spares list.
System Optimization
  • CO₂ setpoint tuning for gymnasium ventilation.
  • Optimized schedules aligned with occupancy and events.
  • Boiler return-temperature control for condensing mode.
Efficiency Improvement
  • Continuous monitoring with KPI dashboards and alerts.
  • Seasonal recommissioning and performance reviews.
  • Roadmap for incremental efficiency upgrades.

Result: a high-performance sports facility with verified ventilation control, efficient heat recovery, and a monitoring framework to protect savings over time.
