6.7 HVAC Secondary Systems

This group of building descriptors relate to the secondary HVAC systems. There is not a one-to-one relationship between secondary HVAC system components in the proposed design and the baseline building since the baseline building system is determined from building type, size and heating source.  Appendix A shows the applicability of each building descriptor for the eight baseline building systems. Depending on the nature of the proposed design, any of the building descriptors could apply.
