Fresh-Aire UV: Outdoor Air Estimation SoftwareCustom-written, SCOPE is a free software tool that calculates minimum outdoor air allowances and return-on-investment (ROI) results when applying ventilation rate procedure (VRP) and the indoor air quality procedure’s (IAQP) sorptive air cleaning provision. The software takes the guesswork out of executing ASHRAE 62.1’s VRP or IAQP allowances, the company said. Users can register for SCOPE at and download a MicroSoft Windows®-compatible executable file. Required input parameters include unit size, airborne contaminants of concern (CoC), building use, and other related statistics. Software calculations include the clean air delivery rate (CADR) of more than two dozen common outdoor and indoor CoC. It automatically calculates and inputs weather data based on more than 50 selected North American geographical regions. Results are exported as a full-color PDF file that displays the amount of ASHRAE 62.1-compliant outdoor air reduction allowed, energy savings, ROI (in U.S. dollars) and air purification equipment payback as a result of employing the APCO Rack System.
