Technical studies
and diagnostics
As part of our support missions for sustainable and efficient construction or rehabilitation, we carry out technical studies to facilitate decision-making by project owners.
- Renovation and energy optimization of installations (heating, air conditioning, ventilation)
- Diagnosis of malfunctions in distribution networks (heating, hot water, cold water)
- Legionnaires' disease prevention
FAQ
Technical studies and diagnostics
What do you mean by “technical studies” vs. “diagnostics”?
Technical studies: HVAC/Plumbing/Ventilation sizing, calculation notes, schematic diagrams, power balances, equipment selection, budget estimation, and tender documents.
Diagnostics: on-site assessment of existing installations (boiler room, substations, networks, ventilation), measurements (temperatures, flow rates, pressures, CO₂), analysis of malfunctions, and prioritized action plan (adjustments, balancing, replacements).
Diagnostics: on-site assessment of existing installations (boiler room, substations, networks, ventilation), measurements (temperatures, flow rates, pressures, CO₂), analysis of malfunctions, and prioritized action plan (adjustments, balancing, replacements).
What types of diagnoses do you actually carry out?
• Boiler rooms & substations: efficiency, regulation, heating curves, backup/replacement, safety.
• Hydraulic networks: balancing, pressure losses, valves, circulators, temperature difference (ΔT), corrosion/sludge (treatment lines).
• Ventilation: flow rates, AHU/VAS adjustment, air renewal, noise levels, airtightness.
• IAQ (Indoor Air Quality): spot measurements of CO₂/TH/T°, summer comfort, operating recommendations.
• BMS/Metering: verification of points/setpoints, alarms, time strategy, meter reliability.

What quick benefits can be expected without "major work"?
Useful: adjusting water temperature control, optimizing setpoints and schedules, balancing networks, correcting faulty sensors/valves, overhauling the building management system (programs, alarms), isolating critical points, and calibrating ventilation.
Typical results: stabilized comfort, reduced consumption and breakdowns, improved operational clarity—useful for deciding on potential replacements.
Businesses: periodic audit (or ISO 50001 as an alternative). Check if you become subject to the 2025 regulations based on your consumption levels. tennaxia.com+1
