Education Restructuring & Extension

Sector: Education Year: 2015 City: Grenay, France Gross Floor Area (GFA): 6,300 sqm Total Cost: €13.3 million Scope of the Mission: Energy Project Management (~4 years: Program, Design, Construction, Commissioning, Occupancy, Maintenance)

Restructuring and extension of an education facility delivered under HQE with RT2005 compliance. High-performance envelope (external insulation, double-glazed windows), PV membrane and solar thermal integration, water recovery system, gas condensing boiler, dual-flow AHUs with >80% heat recovery, and an energy & water monitoring system. BAARCH led the full lifecycle from programming to post-occupancy maintenance.

Detailed Assessment

Project type: restructuring & extension with HQE / RT2005 targets.
Envelope strategy: external insulation and double-glazed windows.
Renewables concept: PV membrane and solar thermal panels.

Performance Evaluation

Baseline KPIs defined for energy and water use.
Verified heat recovery efficiency >80% on dual-flow AHUs.
Assessed seasonal efficiency of the condensing boiler.

Diagnostic Testing

Functional tests: AHUs, boiler plant, PV and solar thermal loops.
Air and water balancing; controls sequence verification.
Metering validation within the monitoring system.

Maintenance Review

Preventive maintenance plan and calibration routines.
Operator training for seasonal changeover and alarms.
Asset register and critical spares list.

System Optimization

Optimized heat recovery control and setpoints.
Boiler return temperature management (condensing mode).
Schedules aligned with occupancy patterns and seasons.

Efficiency Improvement

Continuous monitoring with KPI dashboards and alarms.
Seasonal recommissioning checkpoints and performance reviews.
Roadmap for incremental efficiency upgrades over time.

Result: an energy-efficient education facility with verified heat recovery, optimized boiler operation, and a monitoring framework in place to sustain performance in use.
