Measurement devices must be permanently installed on each outdoor air intake at each air-handling unit (AHU) or central mixing plenum.
You can only use approved equipment to perform the continuous monitoring, including Pitot tubes, Venturi meters, rotating vane anemometers, and mass air flow sensors.
Monitoring must be performed for at least 80% of the building’s total outdoor air intake flow serving occupied spaces.
Buildings with some level of existing monitoring, or a BAS, have the best chances at successful completion of this credit because implementation costs will be lower.
Install permanent outdoor airflow measurement devices that provide continuous monitoring and generate an alarm if the minimum outdoor airflow rate falls more than 15% below the minimum rate specified in the building operating plan. You should have already figured out this minimum airflow rate for your building to meet the requirements of IEQp1: Minimum Indoor Air Quality Performance.
Follow Case 1 if you have mechanical ventilation systems.
Case 1: Mechanical Ventilation Systems
This credit has three compliance paths: Cases 1, 2, and 3. Unlike many other LEED credits where you choose one to follow, you may need to follow two or three of these, depending on your building:
Case 1 is for predominantly mechanically ventilated buildings.
Case 2 applies to buildings with densely occupied spaces such as cafeterias or meeting rooms.
Case 3 applies to naturally ventilated spaces.
Many waste haulers will provide a breakout of recycled materials by material type upon request, but it is a good idea to check with your hauler to see if they provide this level of detail before implementing your program so that you can create your own process for tracking recyclables if necessary.
If possible, track individual waste stream components that are diverted from the landfill and isolate these values for the purposes of documentation. Ask your waste hauler about providing itemized hauler reports so that you can consistently track the separate waste streams from your building’s ongoing consumables waste, such as paper, cardboard, and glass.
