Government Facility Restructuring – Energy
Restructuring of a government facility following HQE and RTex retrofit principles. The project achieved high energy performance through internal insulation with double-glazed windows, airtightness level Q4 < 1.7 m³/m²·h, LED lighting with dimming, and gas boiler technology using hydro-ejectors. Dual-flow AHUs with > 80% heat recovery and an energy & water monitoring system were integrated. BAARCH oversaw the full project lifecycle from programming to post-occupancy maintenance.
Detailed Assessment
- HQE-compliant retrofit under RTex methodology.
- Envelope upgrades with internal insulation and high-performance glazing.
- Air leakage testing confirming Q4 < 1.7 m³/m²·h.
Performance Evaluation
- Measured airtightness, lighting efficiency, and thermal envelope performance.
- Verified > 80% heat recovery efficiency in AHUs.
- Assessed seasonal efficiency of hydro-ejector gas boiler.
Diagnostic Testing
- Performance tests on heating, ventilation, and lighting systems.
- Monitoring system calibration and functional verification.
- Airflow balancing and control sequence validation for AHUs.
Maintenance Review
- Preventive maintenance plan for HVAC and lighting systems.
- Operator training for monitoring dashboards and seasonal adjustments.
- Maintenance logs and spare-parts inventory creation.
System Optimization
- Optimized setpoints for heating and ventilation.
- Lighting dimming schedules to reduce peak loads.
- Adaptive control strategies for occupancy variations.
Efficiency Improvement
- Continuous monitoring with energy/water KPIs.
- Seasonal recommissioning procedures.
- Long-term energy efficiency improvement roadmap.
Result: a retrofitted government building with enhanced airtightness, efficient HVAC and lighting systems, and an active monitoring framework to ensure sustained performance.
