system allows building operators to monitor and
control building temperatures, which meets one
part of the LEED credit requirements. In GSA
buildings that have active humidification systems,
P100 also requires relative humidity sensors and
controls that are tied back to the DDC system.
This will meet the second part of the LEED
requirement; however, it will not be applicable on
all GSA projects.
