All of the following are true of IEQ Credit 7.2- Thermal Comfort- Verification except:

A. The credit requires surveying building occupants
B. The credit will result in high implementation costs
C. The credit requires a permanent monitoring system for NC/CI projects
D. Residential projects are not eligible for this credit
E. Credit can only be achieved if project achieves 7.1 Thermal Comfort- Design

My guess is either C, D. I say C because the permanent monitoring system is only for NC projects, right?

I did not see anything regarding residential for this credit in the reference guide. Anyone else have any guesses?
