System Solutions for Smoke Ventilation and Natural Ventilation – Engineering, Safety & Indoor Climate

Modern building automation demands rigorous energy efficiency alongside failsafe life safety. Combining certified smoke and heat exhaust ventilation (SHEV) with automated natural ventilation delivers properties with superior indoor climate and premier fire safety – seamlessly integrated into the same facade and control architecture.

Life Safety & SHEV

Certified Smoke Ventilation (EN 12101)

During a fire incident, toxic smoke and heat present the greatest hazard to human life. An engineered smoke ventilation system automatically opens smoke vents and facade windows in stairwells, atriums, and escape routes to keep corridors free of smoke and facilitate firefighting access.

Fully compliant with BBR regulations and EN 12101-2 natural smoke vent standards.
72-hour battery backup power supply in accordance with EN 12101-10.
Supervised fire alarm loops and manual break-glass call points with priority override.

Indoor Climate & Energy

Natural Ventilation & Night Cooling

Natural ventilation utilizes thermal buoyancy (stack effect) and wind pressure to supply continuous fresh air without noisy mechanical fan coils. The system regulates indoor temperature and CO2 concentrations with pinpoint precision in educational, commercial, and public facilities.

Automated night purging reduces daytime cooling energy demand by 30–50%.
Demand-controlled window opening based on temperature and indoor air quality sensors.
Substantially reduced operational energy consumption and carbon footprint.

Actuators & Bus Automation

Actuator Sizing & MotorLink® BMS

Actuator selection is governed by window dimensions, weight, opening stroke, and aerodynamic requirements. WindowMaster MotorLink® technology provides true digital bus control with millimeter precision, speed modulation, and full two-way feedback to building management systems.

Compact chain and spindle actuators providing pushing forces up to 1,500 N.
Seamless integration into BMS/SCADA infrastructure via BACnet, KNX, or Modbus.
Real-time position feedback, anti-entrapment monitoring, and diagnostic alerts.

Engineering Checklist for Window Automation Systems

Actionable guidance for architects, MEP/fire engineers, and property managers:

Contact our engineering team for sizing calculations

1. Window geometry & aerodynamic area

Identify opening type (top-hung outward, bottom-hung, roof light) and calculate both geometric and aerodynamic free area (Av).

2. Safety classification & voltage

Select 24V DC with battery backup for life-safety smoke ventilation or 230V AC for dedicated comfort ventilation installations.

3. Weather protection & entrapment safety

Integrate rain and wind weather sensors to prevent moisture damage alongside certified anti-pinch safety under EN 60335-2-103.

4. Regulatory compliance & maintenance

Establish an accredited maintenance protocol for annual functional audits and battery replacement schedules.
