Even one piece of equipment can tip your calculations to compliance or noncompliance. Use the calculator in the LEED Online submittal template to run calculations from the beginning of HVAC system selection (note that your project has to be registered through LEED Online to download those forms). This gives a sense of how far from compliance a system may be; teams then get a better idea of how significant a change may be required. Note that annual leakage and end-of-life refrigerant loss rates are set to defaults but can be edited if needed. 

If your project building is connected to a district chilled-water system, you have to include all the chillers in that system in the calculations, even if they are outside your project’s scope or control. As a rule of thumb, if the system is serving

If your project building is connected to a district chilled-water system, you have to include all the chillers in that system in the calculations, even if they are outside your project’s scope or control. As a rule of thumb, if the system is serving your LEED project it should be included in calculations, whether it is within your project scope of work or not.
