## Smart Smoke Extraction System Deployment Guide for Existing Buildings in Villeurbanne

Why Villeurbanne Needs a Smart Smoke Extraction upgrade

• EU energy‑efficiency directives (2018/844) require reduced HVAC energy consumption while maintaining safety.
• French ERP regulations (Arrêté du 25 janvier 1980) mandate automatic smoke control in public‑access buildings.
• Urban densification in the Confluence district increases fire‑risk exposure, demanding faster smoke clearance.

Modernizing smoke extraction aligns fire protection with sustainability, occupants’ well‑being, and legal compliance.

Core Components of a Modern Smoke Extraction System

1. Smart Smoke Sensors

Feature	Benefit
Multi‑criteria detection (optical + thermal)	Reduces false alarms by up to 30 %
IoT connectivity (LoRa, NB‑IoT)	Real‑time status in the Building Management System (BMS)
Self‑diagnostic and predictive maintenance alerts	Extends sensor life > 5 years

2.Variable‑speed Exhaust Fans

• EC (electronically commutated) motors deliver up to 90 % energy savings versus AC motors.
• PWM speed control adapts airflow to the size of the fire zone, complying with EN 12101‑2.

3. Automated Smoke Vents & Dampers

• Motorised louvers open within 3 seconds when smoke is detected.
• Fail‑safe spring return ensures operation even during power loss.

4. Integrated Fire Alarm & BMS Interface

• Modbus/KNX or BACnet protocols allow centralized monitoring.
• Alarm prioritisation (smoke → heat → manual call point) streamlines operator response.

Step‑by‑Step retrofit Guide for Existing Buildings

1. Audit Existing Infrastructure

• Conduct a CFD (Computational Fluid Dynamics) simulation of smoke spread.
• Map current exhaust fan capacities and vent locations.

2. Select Compatible Smart Devices

• Choose sensors with CE‑mark and ISO 7240‑2 certification.
• Verify fan controllers support the building’s BMS protocol.

3. Install IoT Gateways

• Place gateways at strategic points to minimise latency (< 200 ms).

4. Program Control Logic

• Implement staged opening: 30 % → 60 % → 100 % fan speed based on smoke density.
• integrate with fire doors to ensure pressurisation of escape routes.

5. Test & Commission

• Perform functional tests per NF P 92‑500.
• Record results in a digital log for audit compliance.

6. Train Facility Staff

• Conduct quarterly drills using the new alarm sequences.

Benefits of Modern Smoke Extraction in Villeurbanne

• reduced evacuation time – 25 % faster smoke clearance compared with legacy systems.
• Lower energy consumption – up to 40 % reduction in fan electricity use.
• Enhanced regulatory compliance – meets 2024 French fire‑safety update and upcoming EU “Smart Buildings” roadmap.
• Improved occupant confidence – real‑time visual alerts via mobile app increase perceived safety.

---

Practical Tips for Building Owners

• Prioritise zones with high occupancy (schools,offices,hospitals) when budgeting for upgrades.
• Leverage government incentives – the French “Plan Bâtiment Durable” offers a 20 % tax credit for energy‑efficient fire safety retrofits.
• Bundle upgrades – combine smoke extraction with HVAC filter upgrades to streamline permits.
• Use certified installers – ensure the contractor holds the “Attestation de Compétence en Sécurité Incendie” (ACS).

Real‑World Example: Villeurbanne Confluence Office tower (2023‑2024)

• Project scope: Replace three 2.5 kW exhaust fans with EC fans, install 48 multi‑criteria smoke sensors, and integrate with the existing KNX BMS.
• Results:
• Energy use for smoke extraction dropped from 12 MWh/year to 6.5 MWh/year.
• Fire drill evacuation time reduced from 4 min 30 s to 3 min 10 s.
• received the “Eco‑Fire Innovation” award from the French ministry of Ecological Transition.

Frequently Asked Questions (FAQ)

Q1. How does a variable‑speed fan differ from a traditional constant‑speed fan?

A: Variable‑speed fans adjust airflow based on real‑time smoke density, preventing over‑pressurisation and cutting electricity use by up to 60 %.

Q2. Are IoT‑enabled smoke detectors vulnerable to cyber attacks?

A: When configured with encrypted TLS interaction and isolated VLANs, the risk is comparable to standard IT equipment. Regular firmware updates are crucial.

Q3. What is the typical lifespan of a modern smoke extraction system?

A: With predictive maintenance, components such as EC fans and sensor modules can exceed 15 years before major replacement.

Q4. Do retrofits affect the building’s fire rating?

A: Properly designed retrofits maintain or improve the existing fire resistance classification, provided they meet NFPA 72 and French ERP standards.
