Action Steps

To comply with Option 2, you’ll need to calculate the weighted impact of the following characteristics of all refrigerants used in your project: 

• environmental impact (through destruction of the ozone layer and the concentration of greenhouse gases in the atmosphere);
• coolant capacity and refrigerant charge (determined by equipment specs); 
• rate of refrigerant leakage (determined by equipment life);
• and end-of-life refrigerant loss (largely determined by equipment specs).

If your project has no cooling system or uses a system without refrigerants, you can achieve the credit through Option 1 (“do not use refrigerants”). Document your credit compliance path with appropriate supporting documents by completing the credit form and providing cut sheets or other confirmation of the system type.

Complete the table of equipment and appliances in LEED Online and verify that 50% of the rated power is Energy Star-labeled.

Demonstrate LPD compliance using ASHRAE compliance forms— or if your project developed an energy model, use the outputs from the model to fill in the forms. Compliance forms are available on the ASHRAE website for free download.

Demonstrate compliance using the ASHRAE forms or a sign-off by the registered architect and engineer. 

Develop the compliance documentation. Compliance can be demonstrated with ASHRAE 90.1-2007 compliance forms, or the LEED Online form may be signed by the registered architect and design engineer. 

Confirm that the system components and system efficiency are the same as that specified. 

Install the systems as specified. Have the mechanical engineer and the commissioning agent visit the site to ensure that the correct systems are being installed. 

Update the table of appliances and equipment after the construction documents are complete to track any reduction or increase in the amount of Energy Star-labeled equipment and appliances. If the Energy Star-labeled systems do not make up 50% of the total rated power, revisit the list to identify which appliances and equipment can be upgraded to meet the threshold. 

Ensure that the specified lighting system and controls are installed.
