Make sure that compliance and coordination with this credit is called out in the IAQ management plan if your project is pursuing IEQc3.1: Construction Indoor Air Quality Management Plan—During Construction. 

Use MERV 8 filtration on any permanent mechanical system equipment used during construction. This adds to construction management tasks and could easily be overlooked and lead to loss of the credit.

Use temporary ventilation systems instead of the permanent HVAC units during construction. This prevents contamination of new ductwork during the construction process. 

Keep HVAC&R equipment cut sheets on file in the case that there is an urgent problem with the refrigerant in the equipment so that the refrigerant can be handled or replaced properly. 

Calibrate occupancy sensors and other lighting control systems (if included) after the installation of all office equipment and furnishings. Installing office equipment and furnishings after calibrating the lighting control systems could cause poor system performance.

Document credit achievement through LEED Online. You'll need to provide the following information: 

• occupancy type for building spaces 
• number of occupants or spaces (as applicable to space type) 
• a description of the lighting controls 
• lighting control types   
• project drawings showing the different lighting control types and locations.

Commission lighting systems to confirm their performance in concert with the commissioning credits EAp1 and EAc2.
