From Mark Schatz
October 24, 2000
One of the issues raised in Monday's meeting on grease hood exhaust was whether or not
the project was submitted to the County Health Department. I have followed up on this
with George Jansen. The city plan checker determined that the kitchen was so small that
it did not require county health department review. Therefore, the city chose not to
forward it to them for their input.
However, our consultant did fill out forms for the exhaust ventilation systems, copies of
which I have found in our files. I have attached copies of these for your review and/or
use.

Memo to Mark Nelson
• Cc: Mike McCrary, Travice Whitten
From Mark Schatz
BSA Architects
December 5, 2000
I am writing to follow up on two issues related to the building departments concerns about the kitchen
exhaust hood in the Cupertino Senior Center.
1. To the best of my knowledge, then: is nothing in the code that would require us to extend the finish
ceiling above the metal hood housing. This would in fact, be extremely difficult to do because of the
large numbers of ducts located immediately above the hood. Typically, we simply butt the ceiling
grid up to the face of the hood. In chis case, we have also proposed adding insulation into the
extension of the metal housing of the hood.
2. Concern was raised regarding the bracing of the wall onto which the hood is mounted. Our
structural engineer has reviewed these conditions and concluded that the existing bracing is
sufficient. A letter from him is attached.
I hope that this memo, in addition to the materials from Craig Linford at Mechanical Design Studio, will
be sufficient for obtaining the final approvals for the hood.

Thank you for Lhe attached method to calculate exhaust flow
rates. The method described of taking the Lotal lenqth of Lhe
hood "L" An feet and multiplying it by the r.fm rating per
iineal. foot (appropriate for Lhe hood based on the maximum
cooking equipmenL temperature) will result in Lhe tot -Al cfm
for the hood.
If you have any questions, please feel free to direct any
calls to me.
Very truly yours,

Minimum Exhaust Flow Rafts
To determine the minimum exhaust flow rates for rcmini Air Systems I LI.. listed hoods the following
procedures should he followed,
1. Choose a style of hood that you would like to use in your cooking facility from the Gemini Air
Systems catalog.
2. Measure the total length and width of the cooking equipment that will he operating under the hood.
Add the specified overhangs to the overall length and width of the couking equipment. This will give
you tale minimum hood size.
3. Record the hood length. 'Rte area of the hood drat is considered the length is shown in figure A. only
the length or the hood is used In detcrmining the minimum exhaust airflow rates. The width (+ides) and
the highth of the hood are not used to determine exhaust airflow rates.
4. Verify that lite hood you have choler has been tcatcd to vemilatc at the maximum cooking
tempenttures of the cooking equipment you intend to operate under it
i. Choose the correct formula for the cooking equipment operating under the hood. The cooking
equipment operating under the hood with the highest cooking temperature is used to determine the
minimum exhaust airflow tate formula. Return to the ficmini Air Systems catalog and relocntc the
• style orhood you have chosen. Find the temperature that corresponds to the highest operating
tempcmuire of the cooking equipment operating under the hood. Match that temperature with the
accompanying minimum exhaust airnuw me fornnda.
b. Multiply the hood length by the minimum exhaust air flow rale formula. This figure is the minimum
exhaust airflow rate for this (food. _

SUBJECT: Kitchen Hood Wall
Mark, at your request I have reviewed the lateral stability of the wood stud wall supporting the
• kitchen hood. Based on the as -built construction of the wall (continuous double 2x4 top plates lapped
at cross walls at both ends, plus a horizontal 2x4 cross brace fastened to the perpendicular cross wall
with 3-16d nails at both ends to the top plates) and the information in the construction documents,
the wall appears to be adequately braced for compliance with the 1997 UBC.
The bottom of the kitchen hood should be fastened to 3x or 4x blocking in the stud wall with 4414
wood screws, equally spaced. The top of the hood shall be braced back to the stud wall with an angle
located at each rod hanger. See option #2 on the attached sketch for complete information! i rr,
