Description

As we add Thermal Comfort Parameters, the following parameters (from BLAST) are closely related to People and should be included on the People statement:

Metabolic Rate
Clothing Insulation
Work Efficiency

The Activity Level is based on the ASHRAE Heat Gain of people in
Conditioned Spaces which is further based on a heat gain at a specific
temperature.

Should we move totally to the more specific (from a user's point of
view), metabolic rate and clothing insulation? (Not sure about work
efficiency -- do we really need that? It would seem to be a modifier on
Metabolic rate) And can we derive the activity level (i.e. heat gain) from
the mets and clo values? (Based on the actual zone temperature.) Or will we need to have multiple PEOPLE:ActivityLevel and PEOPLE:MetRate or similar definitions.

Fix

2000.03.16 (RS): Thermal comfort has been added to EnergyPlus and the input parameters are slightly different from the original BLAST implementation. The first difference is that heat gain from occupants is entered as Watts rather than mets. This is due partially to the fact that the comfort and people statements have been consolidated into a single input statement. So, the request to include thermal comfort parameters in the people statement has been fulfilled.

In the PEOPLE statement, activity level and metabolic rate are essentially the same thing from the user's standpoint. I believe all of these concerns have been addressed with the recent changes to the PEOPLE statement and the addition of the Fanger thermal comfort model (with KSU and Pierce to follow).
