Hi, I have question regarding option (b) under part 1, which states that:
Building policy states that all cooling coils are inspected on a quarterly basis for mold growth and cleaned if necessary. Dated photos demonstrating adherence are provided to the IWBI on an annual basis.
According to my understanding and after discussion with mechanical engineer, this work can cost very high. For example: in a typical medium size office floor, number of cooling coils are approximately 90. And it takes 30 minutes to inspect every coil according to ISO 16000:18. This will add up to 45 hours of job per floor. Since, frequency is quarterly this will be significant operating cost per year.
Do you have any thoughts about this? or what is the intent behind this feature requirement ?
