Re: 221 E Mountain BDR Comments – Mechanical Equipment Roof Area Analysis
ME #: 15085
Dear Seth,
Per your request in our phone conversation dated 6/23/2016, this letter is a summary of the
required mechanical HVAC roof top equipment for the project referenced above. This letter
should also be considered our response to the Fort Collins BDR comment (BDR160011) we
received on 05/27/2016 for the project referenced above. Section 3.8.17 of the City of Fort
Collins Land Use Code, mechanical equipment exceeding the maximum building height is to be
limited to 5% of the total roof area.
Currently, we anticipate to provide the new four (4) story building with two (2) packaged rooftop
units (RTU) to provide the International Mechanical Code (IMC) required heating and ventilation
air to the space. In addition, a single restroom exhaust fan (EF) will provide the IMC required
ventilation to the core group of restrooms. At this time, it is expected that a future restaurant
tenant will occupy a portion of the first floor retail space, thus, as part of this analysis, we have
included the kitchen hood exhaust fan (KEF) and makeup air unit (MAU) that is expected to be
mounted on the roof. Lastly, per Poudre Fire Authority, a fire pump will be required for the space
which will need a backup generator. Due to space limitations, the generator is currently planned
to be placed on the roof.
Attached you will find a summary of each roof mounted piece of mechanical equipment and its
total percentage of roof area covered. Per your request, we have included both the area of the
fourth floor roof, and an analysis of the total roof area, which includes the lower third floor roof
area. The table provided in the attachment indicates roof area of all mechanical equipment
relative to the total roof area (including both roofs) is approximately 5.22%. The mechanical
rooftop units, RTU-1 and 2, are standard packaged equipment and they have been sized to
handle 30% outside air (relative to total airflow). The 30% outside air flow rate is the industry
standard recommendation for maximum amount of outside air a unit can adequately temper
during the design day conditions. Anything above that would generally require a larger air
handling unit.
We feel that the code required space heating and ventilation equipment has as small of a foot
print as allowed for standardized equipment and we request that the City of Fort Collins allow
the units as currently configured to be provided and placed on the roof. In addition to the
summary, cutsheets of each proposed piece of roof mounted mechanical equipment has been
provided for your reference.

NOTE: Roof Opening Requirements:
Minimum Roof Opening: The minimum roof opening size is the illustrated duct diameter plus 0.25 in. on all sides.
For example: If the duct size is 14 x 14 in. square, the minimum roof opening size is 14.5 x 14.5 in. square.
Maximum Roof Opening: There must be a minimum perimeter of 1.75 in. between the roof opening and the roof curb.
For example: If the roof curb is 75 x 30 in. square, the maximum roof opening is 71.5 x 26.5 in. inches square.
NOTE: The weatherhood and filter sections of the make-up air unit are not supported by the curb.
This is by design, in order to help alleviate water infiltration issues. MUA Unit supports are shipped loose with unit.

Clearance to combustibles is defined as the minimum distance required between the heating source and the
adjacent combustible surfaces to ensure the adjacent surface's temperature does not exceed 90 F above the
ambient temperature.
Recommended Minimum Service Clearances
Housing 32 and less 42 in. on the controls side of the unit
Housing 35 and higher 48 in. on the controls side of the unit
To ensure ample space for component removal (evaporative cooling media, coils, filters, etc.), service clearances
should be 6 in. wider than the width of the module itself.
