Revision history [back]

All;

I am curious to learn about others' approaches for handling baseline radiant heating AND cooling; when if comes time to build the baseline model. Whether this be radiant gas heating at an outdoor stadium or restaurant or a radiant slab for cool. While a several software can account for the energy usage in a proposed design, either directly or approximately; I haven't see and don't know of any guidance on how this should be reflected for baseline models. For example, California Energy Code and ASHRAE 90.1-2010 define conditioning of 'enclosed areas; but with radiant conditioning this isn't a requirement. It also has applications where forced air conditioned would be impractical. So, how are appropriate baseline systems created ?

As an extension to this, how has it been handled within your chosen software package? Thanks in advance for your thoughts.
