According to the U.S. Environmental Protection Agency, we spend over 90% of our time indoors. Much of this time is spent in our offices. Studies show that cleaner air in office buildings can improve productivity and reduce absenteeism. High Efficiency Air Cleaning – Dynamic Air Cleaners remove dangerous airborne particles that other air cleaning systems miss…including odors, VOCs, smoke, bacteria, allergens, fine dust, molds and pollen…without producing any harmful ozone. When properly applied Dynamic Air Cleaners can have a significant impact on removing odors from outside air as the air comes through the ventilation system.

Precise measurement of air quality. The carbon dioxide content of room air gives a measure of the air quality, especially as it relates to the health and comfort of the people occupying the building. Air quality can be adversely affected by increased levels of carbon dioxide, carbon monoxide, volatile organic compounds (VOCs), particulates, or bacteria. Increased ventilation reduces the level of all of these unwanted contaminants. Measuring the CO2 concentration provides an economical way of ensuring that there is sufficient air circulation and prevents over-ventilation which can add unnecessary heating or cooling costs.

The Heating Ventilation and Air-condition (HVAC) market in the Building Automation industry focuses on controlling atmospheric conditions to make them more suitable. Among the conditions controlled by these systems are temperature and humidity. aIST’s thin film platinum and nickel temperature sensors are ideal for heat meter monitoring and control applications in HVAC because of their high resolution and long term accuracy. Additionally, IST’s thin film capacitive humidity sensors are ideal for controlling the relative humidity of an environment due to their rapid response times and accuracy over time. Thermal mass flow sensors also have applications in the HVAC industry as an indicator of duct airflow

A “white room” is a room where aeration, ventilation, air filtration, building materials and operating procedures are prescribed in order to control the concentration and quality of the particles which are present in the air and to meet adequate cleaning standards.

For cleaner air in health clubs, gymnasiums, arenas and stadiums, Dynamic Air Cleaners are proven winners. Dynamic Air Cleaners can be found at the UNI-Dome, home of the University Of Northern Iowa basketball and football programs. In a recent IAQ upgrade to reduce the ventilation air into the building, which was constructed in 1976, Cosatini Engineering (Chicago) used the Ashrae 62 IAQ procedure to calculate a reduction of outside air needed in the facility. The original plan was to use 95% cartridge filters with a bank of carbon to meet Standard 62 requirements. Dynamic V-Banks were used in place of the passive cartridge filters in two 125,000 cfm air handlers.

Roads, railways and airports are the largest source of transportation noise and frequently effects development land for houses, schools and hospitals. Noise sensitive developments adjacent to or affected by transportation noise require the careful assessment of these sources, either by measurement or prediction and often both. This assessment enables the correct specification of the building envelope (walls, windows, ventilators and roofs) to achieve appropriate internal noise levels in new developments. Here social housing providers are often at the forefront of providing superior internal ambient noise climate for their tenants and require precise specification of glazing and ventilation systems. New or altered forms of transportation sources near to existing noise sensitive sites also require careful assessment to minimise impact.

Many industries are involved in coating products with solvent-borne materials and then employing ovens or dryers to remove the solvents from the finished product. The key hazard is an explosion from the build up of solvent vapors in the oven or dryer atmosphere. This buildup could occur by a malfunction in the production process such as: a sudden or improper amount of coating, a change in ventilation controls or excessive speed. In any of these cases, the concentration of flammable vapor has an opportunity to rise above safe levels, creating a potentially explosive mixture of vapor in air.
