Inquiry

Is it acceptable to utilize a sampling strategy in fulfilling the requirements of EAp1 Commissioning under LEED Existing Buildings Version 2.0? The project in question is a hotel, with individual fan coil units for each room. The language from NC 2.1 stated " Similar units that are numerous (e.g., many smaller rooftop packaged units, air terminal units and exhaust fans) may require a specific sampling strategy." The sampling strategy utilized would be conducted as follows: The fan coils will be randomly tested at 10% of total units (The 1st sample). If 10% of the units in the first sample fail the functional performance tests, another 10% of the group will be tested (The 2nd sample). If 10% or the units in the 2nd sample fail all remaining units in the whole group will be tested.
