EA127 - Credit form

Select one of the following:

Option 1. No Refrigerants or Low-Impact Refrigerants. The project does not use refrigerants or uses only refrigerants that have an ozone depletion potential (ODP) of zero and a global warming potential (GWP) of less than 50. (1 point)

Option 2. Calculation of Refrigerant Impact. Refrigerants in HVAC&R systems minimize or eliminate the emission of compounds that contribute to ozone depletion and climate change. The combination of all new and existing base building and tenant HVAC&R equipment that serve the project comply with the maximum threshold. (1 point)

Option 1. No Refrigerants or Low-Impact Refrigerants.

If low-impact refrigerants are used, provide the names of these refrigerants. If no refrigerants are used, describe why no refrigerants are needed.

Option 2. Calculation of Refrigerant Impact.

Table: Mechanical Cooling and Refrigeration Equipment

Complete the following table for all modes of mechanical cooling and refrigeration equipment with 0.5 lb (225 g) or more of refrigerant serving the project.
Note: Projects that select "Other" must provide documentation of the ODPr and the GWPr values for the refrigerant.

HVAC&R Equipment Type	Units	Qunit ({{ units.qunit }})	Refrigerant	ODPr	Life (Yrs)	Mr (%)	LCODP x 10^5	Impact per {{ units.impact }}	Impact Total

Notes:
1 GWPr, ODPr, Lr and Mr values are auto-populated with default values. Non-default values are not permitted. See the LEED Reference Guide for full table of default values of GWPr and ODPr.
2 Average refrigerant impact per kW must be less than or equal to 13 for 1 point. 2 Average refrigerant impact per ton must be less than or equal to 100 for 1 point.

For projects with variable refrigerant flow (VRF) systems:

Upload the supporting documentation for how the refrigerant charge value for the VRF system(s) was calculated.

For projects with commercial refrigeration systems:

Select one of the following:

Project has attained GreenChill’s silver-level certification for newly constructed stores.

Project meets the following requirements:

Average HFC refrigerant charge is no more than 1.75 lb of refrigerant per 1,000 BTU/h (2.72 g of refrigerant per kW) total evaporator cooling load.
Predicted project-wide annual refrigerant emissions rate is no more than 15%.
Leak testing has been conducted using the procedures in GreenChill's best practices guideline for leak tightness at installation.

Upload the refrigerant equipment schedule and leak test results OR proof of attainment of GreenChill's silver-level store certification for newly constructed stores.

Special Circumstances

Describe the circumstances limiting the project team's ability to provide the submittals required in this form. Be sure to reference what additional documentation has been provided, if any. Non-standard documentation will be considered upon its merits. (Optional)

Upload any additional documentation that supports the claim to special circumstances. (Optional)
