Zone elevation #182

Closed KarenWGard closed 1 year ago

KarenWGard commented 1 year ago

In order to calculate the number of floors in a building for HVAC system zone assignment, we have developed an algorithm that relies on zone elevation.

Currently in the RMI, for each building segment, there is a number given for the number of floors above and below grade, however, simply adding these numbers for all building shells may result in duplication if there are multiple building segments in the RMI. It is common practice in eQuest, (for example), to create multiple building 'shells' to capture complex building geometry. I believe we can anticipate that eQuest building shells will translate to building segments in the RMI.

Suggestion to the Zone data group, add the following data element:

elevation - the average elevation of the zone floor - absolute elevation above ground level (an elevation < 0 indicates that the zone is below grade)

@KarenWGard can you remind me why Zone:floor_name is not sufficient?

KarenWGard commented 1 year ago

it doesn't consistently indicate whether a floor is above or below grade

actually, my bad. I've been corrected. We do not need to distinguish. Floor Name will work. I'll close the issue
