Image
Air flow is produced when central HVAC fan is energized (set thermostat to “fan”)
Image
Image
An elevator shaft vent with a motorized damper in a multistory multifamily building provides smoke and hot gas control in an elevator shaft during fire events; during normal operation the damper remains closed to reduce energy loss.
Image
Continuously-operating ventilation & exhaust fans include readily accessible override controls

Pressure manometers are used to determine the level of pressurization and rate of leakage when conducting blower door testing and building diagnostics
Image
Right - The automated ventilation system has a sensor built in switch that can detect indoor air pollution; if it senses a rise in humidity, VOCs, smoke, carbon dioxide, or small particulates, the system will turn on the nearest fan to eliminate pollution
Image
Image
Right – Smart equipment for homes may include a tablet or touchpad from which the homeowner can control lighting, HVAC, window shades, security, music, and other home automation features.
Image
Right – The builder provided adequate wall space for the solar inverter next to the home’s electric panels.
Image
Right – This bath fan runs continuously at low speed and is activated by a motion sensor to operate a higher speeds.
Image
Right – This plug-in sensor detects indoor air quality issues in a home, including elevated levels of humidity, VOCs, smoke, carbon dioxide, or small particulates; if detected, the sensor can switch on the nearest exhaust fan to remove the pollutants.
Image
Right- An electronic controller operates an exhaust fan, a mechanical damper on a fresh air intake, and the central heat pump’s fan, which draws in fresh air through the damper and distributes it in sync with exhaust fan operation for balanced fresh air.
Image
Image
Image
The green-lit panel next to the fan and light switches is an indoor air quality sensor that will automatically turn on the exhaust fan if it detects a rise in humidity or indoor air pollutants.
Image
Image
The ventilation controller is next to the thermostat and has a manual override button
Image
Image
Image
This bath exhaust fan ventilation control can be set by the HVAC technician for continuous operation, delayed shut off, or a set amount of minutes each hour
Image
This damper located at the top of a stairwell in a multistory building is automatically kept closed to reduce energy loss; it automatically opens during a smoke event.
Image
This home’s balanced fresh air system includes a filtered fresh air intake that is wired to the central HVAC system with timer controls while exhaust fans in the kitchen, bathrooms, and laundry room pull stale and moist air from the home.
Image
This multistory stairwell has an automatic damper that is integrated with the engineered smoke control system.
