Complete all required LEED documentation and upload to LEED Online:

ASHRAE 6.1.1 documentation
IEQc7.1 requirements stated in the OPR and BOD
Thermal comfort variables and established comfort zone
Calculation results (dependent on chosen methodology)
O&M materials (as they are available).

Confirm required calculations based on the finalized design by using a PMV/PPD calculation, the ASHRAE comfort tool, or psychrometric zone chart. 

Variables like clothing levels and metabolic rates are not compliant or non-compliant, but are used instead to determine what appropriate operating ranges will be for a space. You have to show that your HVAC systems will create conditions within these operating ranges. 

Occupant access to thermal controls can help to meet the credit requirements on a space-by-space basis while increasing energy efficiency (by preventing conditioning of a whole HVAC zone rather than individual spaces) and increasing occupant satisfaction by giving people greater control over their thermal conditions. Increasing occupant satisfaction will help projects that are attempting IEQc7.2. 

Provide ample thermal controls for building occupants. This will increase comfort and occupant satisfaction and will keep operating conditions within the prescribed ranges of ASHRAE-55. 

Make sure that the Basis of Design for commissioning reflects compliance with credit requirements and includes design assumptions and load calculations.

Make sure that HVAC engineers track and reconfirm credit-compliant operating ranges through the design development phase.

Make design adjustments to meet credit requirements during design development, keeping in mind the potential impacts on energy use.

Include the following inputs on the LEED Online credit form:

Clothing Insulation and Metabolic Rate of building occupants
Weather design conditions used for peak load calculations
Hours per year that outdoor temperatures exceed design conditions
Maximum Design Humidity
Design Air Speed
Radiant temperature asymmetry
Vertical air temperature difference
Floor surface temperature
Draft.

Pick the best calculation method for demonstrating credit achievement. Document IEQc7.1 using a Predicted Mean Vote/Predicted Percentage of Dissatisfied (PMV/PPD) calculation, ASHRAE comfort tool, or a psychrometric comfort zone chart from ASHRAE-55. The method you pick will likely be determined by the preference and past experience of the mechanical engineer. (See the Resources tab for software options).
