Action Steps

The contractor is the signatory for this credit, and has to confirm compliance with the bullets above and sign off on this credit. 

Develop the Systems Manual, O&M manual, or equivalent. Ensure that the O&M manual includes the following:

• General and specific instructions on the maintenance and operation of controls
• Seasonal settings and changeovers
• Limits in the adjustment of manual controls
• Maintenance and inspection schedule for all thermal and other environmental and thermal condition-related building systems.

Complete all required LEED documentation and upload to LEED Online:

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

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

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).

Examine operating conditions to confirm how likely you are to meet the credit requirements.

Include credit-related information in the Basis of Design for the commissioning credits EAp1 and EAc3. At a minimum this should include:

Review how thermal controls and operable windows affect credit requirements. Projects in very temperate climates may meet the credit requirements through the use of operable windows exclusively, as long as mean monthly outdoor temperatures are between 50°F–92°F. See ASHRAE-55 section 5.3 for details.
