RE: Ritz Carlton -Vail - Lounge Remodel - Test and Balance Results
Project No. 8234.15
Dear Brian,
This letter is in response to the Town of Vail Building Department (TOV) Inspection Summary dated 20
December 2018 for the Vail Ritz - Lounge Remodel Project. It is our understanding that the building
department reviewed the test and balance (TAB) report for the project provided by HVAC-TAB, Inc. and noted
the deviations between the measured air flow and the maximum design air flow listed for the VAV boxes
serving the renovated areas. The TOV has provided a temporary certificate of occupancy (CO) for the project
but will not provide a final CO until they receive stamped calculations from a design professional verifying
minimum ventilation rates are satisfied.
As requested, BG Buildingworks (BG) has completed the ventilation calculations based on chapter 4 of the 2015
International Mechanical Code. The following table lists the minimum required ventilation airflow for each
space along with the original design airflow requirements and the TAB airflow results:
Design (CFM) Minimum
Space VAV TAB Required Comments:
Box Min Max (CFM) Ventilation
(heat) (cool) (CFM)
Private The TAB value exceeds the required
Lounge FPB-8 1500 3600 2032 392 ventilation rate and the minimum VAV
118 box requirement
Library The TAB value exceeds the required
116 FBP-9 600 3500 1967 308 ventilation rate and the minimum VAV
box requirement
The TAB value exceeds the required
FPB-10 400 2150 542 285 ventilation rate and the minimum VAV
Main box requirement
Lounge
117 The TAB value exceeds the required
FPB-11 400 2150 2270 285 ventilation rate and the minimum VAV
box requirement

For each VAV system, the measured TAB airflow exceeds the design minimum airflow requirement and exceeds
the code minimum ventilation airflow rate. Therefore, all areas are receiving more than the code minimum
ventilation airflow and are receiving more than the design minimum airflow for heating.
Please contact me with any questions.
