Dear Mr. Olson:
In your letter of September 19, 1984 for heating and ventilation plan
approval you cite ILHR 63.22 requiring additional insulation at the return
air tunnels.
please b8 advised that the normal temperature of the return air will
be 58 F to 62 F since this air is tempered by the "spill air" from the
refrigerated cases located directly over the air inlets. This calculates
out to a temperature differential with the surrounding medium (ground) of
less than 25 F and, therefore, duct insulation is not required per ILHR
63.22(1)(b)1.
The thermal resistance (R) of the insulation being provided at the
tunnel walls adjacent to the exterior is R -10.8 which exceeds requirements
of ILHR 63.22(1)(a) by 200 %.
Yours very truly,
OK-0" /0+/ ELLIS STONE CONSTRUCTION COMPANY
