HVAC Survey: Visual Guide

Use for reference while filling out the HVAC (heating + cooling) section of the survey

--Please review the following suggested

prioritization for completing the HVAC portion of

the survey.

Prioritization:1. Building owner, tenant, facilities manager

2. Site visit

3. Permit history or City documents

Reminder:

The HVAC survey questions need to be answered for each

building use section in the building

(e.g. a mixed-use building with a restaurant on the first

floor and apartments on floors 2-3 would have 2 use

sections: restaurant + apartments).
