Indoor air quality (IAQ) and its effect on occupant well-being and comfort are essential. Many issues such as sick building syndrome, indoor air quality thermal comfort, visual comfort, and acoustic comfort are a part of the indoor environment. Good indoor air quality requires attention to the building's HVAC system, measure and monitoring, healthy indoor air, air filtration, and pollutant source management. Some good practices in these areas have also been highlighted.

On average, we spend approximately 90% of our lives indoors and take about 20,000 breaths a day. We assume the air is "clean" in the buildings and will not affect our health. It is surprising how little we know about the importance of indoor air quality.

HVAC systems' operation is a critical requirement for reopening and maintaining adequate safe indoor air quality (IAQ). An HVAC system has so many vital components – one being sensors. Sensors verify operation and accuracy to improve system performance and ensure occupant health, safety, comfort, and productivity.

The new 22ADP-584A and the 22ADP-584B duct differential pressure sensors with true auto-zero functionality provide precise pressure measurement. The automatic calibration electronically adjusts the transmitter’s zero reference value every ten minutes. During the adjustment, the output and display values will freeze to the last measured value, eliminating output signal drift due to thermal, electronic, or mechanical effects. The device returns to its normal measuring mode after the one-second calibration process.

Trusted flow measurement is essential in maximizing HVAC system efficiency and ensuring occupant comfort. Glycol prevents heat transfer fluids from freezing in heating, cooling, and air conditioning systems. In systems where pipework is exposed to the exterior environment – rooftop units, free cooling, cooling towers – and green energy applications, such as solar thermal collectors. Glycol is also used in district cooling systems – such as high rise properties where low-temperature energy networks serve several customers.

Belimo is excited to announce the release of new Room Sensors, which complement the existing sensor product range. The Belimo Room Sensors measure temperature, humidity, and CO₂ in a wall-mounted design offering high accuracy and fast response. The sensors are maintenance-free and provide long-term reliability for a comfortable room environment. Integrated with Near Field Communication (NFC) allows for fast programming, commissioning, and troubleshooting with the Belimo Assistant App and a smartphone. The product series consists of Temperature, Temperature with Setpoint, Temperature and Humidity, and Temperature, Humidity, and CO2. Key features include

People spend approximately 90 percent of their time indoors and breathe 3170 gallons (12,000 liters) of air per day. Therefore, it is essential to understand the powerful influence that indoor air quality has on our well-being, especially during this extraordinary COVID-19 pandemic. While the impact of volatile organic compounds (VOCs) on humans has been widely discussed within the context of the 'sick building syndrome,' the role dry air plays in spreading of microbes, including viruses, is often neglected. High performing HVAC systems and proper humidification strategies are required to maintain a stable and healthy indoor air quality in buildings.

Humans spend around 90% of their lifetimes inside closed rooms, therefore its essential to have a pleasant room climate. Air quality, in particular, has a significant impact on our health and well-being. Airtight building shells may well be superior in terms of energy, but they prevent natural air exchange. However, buildings can be fully automated using appropriate ventilation systems and sensors.

Glycol is commonly used to prevent heat transfer fluids freezing in heating, cooling, and air conditioning systems. It is typically found in systems where pipework is exposed to the exterior environment – rooftop units, free cooling, cooling towers, district cooling systems, and green energy applications, such as solar thermal collectors. Glycol into any system can result in large errors in thermal energy measurement when using a meter intended for water alone.
