Buildings account for 44% of final energy consumption in France and 25% of greenhouse gas emissions. The energy transition inevitably means transforming HVAC systems: replacing gas boilers with heat pumps, developing geothermal energy and connecting to district heating networks.
Key decarbonisation technologies
- • Air-to-water heat pumps: COP of 3 to 5 depending on conditions, they are replacing gas boilers in new builds and renovations.
- • Ground source heat pumps with boreholes: stable all year round (COP > 4), ideal for large commercial buildings.
- • Urban district heating networks: supplied by biomass, geothermal energy or waste heat recovery. 900 networks in France.
- • Solar thermal: for DHW production, alongside a heat pump. Covers up to 60% of DHW needs.
- • Wastewater heat recovery: an emerging technology for apartment buildings and swimming pools.
What this means for commissioning engineers
- • Heat pump expertise: commissioning, heating curve adjustment, verification of actual COP.
- • Hybrid systems: managing the heat pump/gas changeover, optimising temperature thresholds.
- • Low temperature: systems running at 40-50°C (underfloor heating, fan coil units) demand more precise balancing.
- • Monitoring: low-carbon systems need instrumented monitoring to guarantee the expected performance.
FIELD TIP
The France Relance recovery plan and MaPrimeRénov' (French renovation grant) are speeding up the replacement of fossil-fuel boilers. It is a huge market for commissioning engineers specialising in heat pumps and energy retrofits.
The energy transition is not just a regulatory constraint — it is a profound transformation of the commissioning engineer's job. Professionals who build their skills in renewables and monitoring will be the backbone of this change.
