Equipment that dehumidifies building spaces used for plant growth and
maintenance shall be one of the following:
1.
Stand-alone dehumidifiers that meet the following minimum
integrated energy factors as measured by the test conditions in Appendix X1 to
Subpart B of 10 C.F.R. Part 430 :
1.1.
Minimum integrated energy factor of 1.77 L/kWh for product case volumes of 8.0
cubic feet or less;
1.2. Minimum
integrated energy factor of 2.41 L/kWh for product case volumes greater than
8.0 cubic feet;
2.
Integrated HVAC system including, but not limited to, heat
pump technology, with on-site heat recovery designed to fulfill at least 75
percent of the annual energy for dehumidification reheat;
3. Chilled water system including, but not
limited to, heat pump technology, with on-site heat recovery designed to
fulfill at least 75 percent of the annual energy for dehumidification reheat;
or
4. Solid or liquid
desiccant dehumidification system for system designs that
require dewpoint of 50°F (10°C) or less.
