As an alternative to the quarterly inspection of cooling coils required in Feature 6, Part 1b, projects may sample 25% of the project’s cooling coils per quarter (representative of all building orientations and equal to 100% of cooling coils per year) through either visual inspection or performance inspection tests. Policy documentation must be provided that includes a detailed description of the inspection protocols for cooling coils and drain pans, and confirming that cleaning will be provided if mold is found before the annual inspection. The inspection and analyses must be performed in accordance with ISO 16000-18 and ISO 16000-17.
Note that dated photos must still be provided to IWBI on a yearly basis.
