GENERAL<br />
Refrigerants<br />
� Demonstrate that all refrigerants to be installed within the project site boundary<br />
have an ozone depletion potential (ODP) of zero<br />
Fire Suppression <strong>System</strong>s<br />
� Demonstrate that all gaseous fire suppression systems to be installed within the<br />
project site boundary have an ozone depletion potential (ODP) of zero<br />
This credit only refers to refrigeration systems contained within the site boundary; (i.e.<br />
district cooling systems which provide only chilled water to the site are not subject to<br />
the requirement of this credit)<br />
ADDITIONAL REQUIREMENT/CLARIFICATIONS<br />
None<br />
This is a requirement. There are no Credit Points awarded.<br />
� Brief narrative describing how the project meets the credit requirements; and<br />
� Specification extracts for all proposed refrigerants and gaseous fire suppression<br />
systems confirming ODP of each refrigerant and gas is zero.<br />
� Updated narrative describing how the project meets the credit requirements; and<br />
� Manufacturer’s information for all installed refrigerants and gaseous fire<br />
suppression systems confirming ODP of each refrigerant and gas is zero.<br />
� The ozone depletion potential (ODP) of various refrigerants is given below:<br />
