Humidity is measured between 0 - 100% and is universally accepted as being optimal when it is 40% and where in this index the contribution will be 0, but at a Humidity reading of 0%, the contribution increases to 25% and similarly when humidity reaches 100% it contributes 25% to the index. See Slide1 for details.
