Like many businesses, we want to provide the healthiest working environment for our employees. This case study discusses a three-tiered approach to providing clean air for our business Dilution, Disinfection and Increased Filtration. The cost of installation, operation and maintenance considerations are included as well. CHALLENGES Assessment of spaces – Our facilities serve multiple functions with different design constraints, which serve different types of mechanical systems so there was no universal solution. Evaluation of solutions – There are multiple technology solutions, which address COVID-19 transmission. Each has its own capacity and restriction for effective deployment. Product availability and ship times – Demand is high and production is limited due to supply chain production capacity and pandemic shutdowns. Orders can take months to fill. Compatibility and placement of the new devices – Evaluating the existing system and the area served is critical to selecting the correct solution. SOLUTIONS Engineering Analysis – We analyzed our current mechanical systems’ capabilities and the impacts of modifications to select the most effective solution and the locations for installation. Controls modifications – We modified our controls settings to bring more outside air into our facilities throughout the day increasing our daytime indoor air changes to twice a day. Bipolar ionization – We added these devices to the supply air throughout our facilities to destroy most pathogens, reduce particulates, eliminate odors, allergens, and other pollutants. Upper air UV lights – We placed these devices in our higher traffic areas for an additional layer of protection. Increased filtration – We upgraded our filtration with MERV 13 filters in our equipment capture as many contaminants as possible. COST Our Initial Investment – $2 per square foot to purchase and install the equipment. Operating Cost– Each bipolar ionization device consumes between $6 and $12 of electricity annually. The UV light arrays consume between $12 and $45 annually. MAINTENANCE Bipolar ionization – Each device requires an annual light cleaning and the ionization tubes are replaced every 2 years. UV lights – Bulbs must be changed annually. THE BOTTOM LINE According the Environment Protection Agency the average American spends 93% of their life indoors. Spending so much time inside a workplace with poor indoor air quality, especially during a pandemic can affect employee health and productivity. Shapiro & Duncan has been providing air quality solutions and upgrades for over 44 years. Our in-house engineering, construction and maintenance teams will work together to build you a plan and reopen your space.
