IBSI offers advanced design and analysis for protecting buildings against airborne disease transmission, mold contamination, nosocomial infections, and the threat of biological weapon (BW) agents. Optimized combinations of filtration and ultraviolet germicidal irradiation (UVGI) can be retrofit in most buildings to provide high levels of protection for building occupants against common airborne pathogens, allergens, respiratory irritants, and intentional releases of BW agents. Other options for improving building aerobiology include pressurization schemes, compartmentalization, detection technologies, surface disinfection systems, mailroom disinfection, and new or developmental technologies. Solutions for specific buildings are tailored to meet client requirements and the unique conditions or concerns that owners may have. Commercial buildings, health care facilities, food industry facilities, airlines, hotels, residential facilities, agricultural facilities, laboratories, animal facilities, and industrial facilities with special needs can be evaluated and retrofitted to meet client concerns.

Computer models of buildings are developed to size air cleaning systems in order to provide the most cost-effective protection possible. Simulations are performed to model releases of biological agents in buildings and air cleaning components are sized to minimize potential infections or casualties. A preliminary feasibility review will be conducted based on building drawings and operating data to determine whether a building is suitable for immunization.
