|
|
| An equipment history record file, noting dates of installation and repair |
|
|
| Air balancing reports and airflow specifications |
|
|
| "As-built" blueprints and system operation plans for mechanical, electrical, and plumbing systems |
|
|
| Is there a rapid response to water damage events? If so: |
|
|

|
|
| Are staff trained how to safely shut down electric and gas supply lines? |
|
|
| Does staff have access to appropriate tools? |
|
|
| Does staff have telephone numbers for fire, police and emergency personnel? |
|

Systems and components |
Yes |
No |

|
|
| Rooftop water elements |
|
|
| Janitors’ closets |
|
|
| Sprinkler systems |
|
|
| Compressors |

| Drains (drainage travels away from the structure, does not drain directly onto the roof or over the side of the building) |
|
|
| Air filters (no dust or debris found) |
|
|
| Air coils (no dust or debris found, level condenser units) |
|

| Condensate drains/lines/pans (no dirt, algae, contaminants or rust found) |
|
|
| Basement flood control and sump systems |
|
|
| Have there been any changes to windows, space use, office equipment or other modifications? If so: |
|
|
| Has the HVAC been reviewed to ensure it continues to meet demands? |
|
|
Heating systems and burners |

|
|
| Heat exchangers — no cracks found? |
|
|
| Proper venting of combustion byproducts (chimneys, vents and connective pipes)? |
|
|
| Appropriate carbon monoxide levels? |
|
|
| Emergency shutdown procedure? |
|
|
| Sufficient return air supply? |
|
|
| Proper balance of ventilation and exhaust systems? |
|
|
| Supply ducts tight, appropriate pressures and airflow? |
|
|
| Is HVAC response to thermostats, humidistats and other control systems adequate? |
|
|
Large building systems |
Yes |
No |
| Do cooling towers have appropriate drainage? |
|
|
| Are fan belts, motors, and other basic system components inspected, lubricated and maintained? |
