As part of Gausman & Moore’s main roles in building design, our engineers are the forward thinkers in HVAC system installation, and it’s contributing factors. The installation of HVAC systems is not only helping to regulate temperature and airflow in a building but to help with a building’s ventilation. Most modern-day facilities, whether they’re industrial or commercial, have some type of ventilation system in place. Their main purpose is cooling—taking warm air out of the space and replacing it with cooler air.
Ventilation is vital for most commercial facilities with any number of occupants, but in some cases, it is a requirement. Many laboratories, medical facilities, government buildings, and schools are required by law to have proper ventilation in place. The main premise behind these regulations is to provide safety by keeping dangerous fumes and/or pathogens away from occupants when they occupy the space or open the sash on a fume hood.
These facilities include:
● University and college research laboratories
● Government agencies
● Small testing and analysis facilities
● Government research
● Commercial and industrial firms
● Hospitals and outpatient facilities
The purpose of proper ventilation in these areas is to control the buildup of emissions and odors, both toxic and non-toxic for humans. If a facility is using chemicals, properly disposing of them is not necessarily enough to ensure effective removal of all chemicals, therefore they must be diluted and ventilated. For laboratories, the room’s ventilation rate will be agreed upon by the owner and our specialists to ensure the best possible system is put in place. For surgery suites, the ventilation air must be tempered, humidified, and HEPA filtered, providing a positive room air pressure.
Regardless of the type of system in place, they must all still fulfill the following requirements:
● Sustain the necessary fume hood exhaust airflow
● Provide optimal room airflow to balance the fume hood exhaust and other exhausts
● Sustain optimal total room exhaust airflow to meet the room’s minimum ventilation rate in air changes per hour
● Sustain enough total room exhaust airflow to allow optimal supply airflow and maintain room temperature and humidity
● Maintain the required contrast between the room’s supply airflow and its exhaust airflow, which will help attain the required static pressurization relationship between an individual room and adjacent rooms/areas
When Gausman & Moore develops a ventilation system for your commercial building, we will first take into consideration the volume of air that will be in the facility and match it will an optimal size ventilator and system. Depending on the size and specific use of the facility (i.e. for chemicals, patients, etc.), we will design for maximum safety and efficiency for all occupants.
