Building HVAC Systems

Meteorological Instruments for Feedback and Control of Building HVAC Systems

Natural Ventilation Monitoring

HVAC (Heating, Ventilation and Air Conditioning) is important in the design of medium to large industrial and office buildings. Conditions can be regulated with respect to temperature and humidity through 'natural ventilation' using outside air without the use of fans or other mechanical systems. Accurate ventilation control requires air flow and other atmospheric condition sensors.

Mechanical or Forced Ventilation Monitoring

"Mechanical" or "forced" ventilation can be used to control indoor air quality. Excess humidity, odours, and contaminants can often be controlled via dilution or replacement with outside air. However, in humid climates much energy is required to remove excess moisture from ventilation air. In this instance outside weather conditions should be measured using an accurate multi-sensor weather station.

Room Air Distribution

Ultrasonic wind sensors are often used in building management systems, providing vital information when access doors dramatically fluctuate indoor air quality and pressure.

Increased Building Safety

In certain high wind speed conditions it may be unsafe for automatic windows and doors to be used. Building management systems often rely on wind sensors to determine when this safety limit has been reached.
