- An accurate type of f low measurement de vice (suc h as a ventur i or sharp edge orifice) if t esti ng
and balancing i s required at a specific pump. Triple-duty valves do not proved accur ate
enough flow m easurements.
- Sound Level Testing
a. Sound level testing shall be specified only in areas where the UIHC project manager deems sound levels to be
a critical issue. Selection of the areas to be tested shall be made during the design phase.
b. Sound level testing shall be based upon ANSI 224.3. NC curves shall be developed by the TBC for inclusion
in the sound level report.
23 07 13 Duct Insulation - Do not install exposed duct lining on supply or return air ducts unless authorized by the Owner.
- Double wall duct (solid outer and inner liners with insulation between) shall be specified on supply air ducts
(and on return air ducts where insulation is required) within Mechanical Equipment Rooms and on risers in
main chases. - Specify rigid insulation or insulation wrap at other locations for supply air ducts and, where deemed necessary, for
return air ducts. Rigid insulation shall be installed using both adhesives and welded pins.
23 07 19 HVAC Piping Insulation- Insulate all mechanical piping systems per ASHRAE 90.1.
- Jacketing:
a. For t ypical mechanical piping systems, use fiberglass insulation with all-service jacketing.
b. Install additional jacketing at locations where physical protection is required.
c. Install PVC jacketing on all piping within Mechanical Equipment Rooms.
d. Install aluminum jacketing for insulated piping outside the facility and at locations where maintenance access
may cause damage.
e. Review with the Owner specific types of jacketing proposed for each installation.
23 08 00 Commissioning of H VAC- Include the TBC on any projects where formal commissioning is specified.
- A Certified AABC Commissioner shall be part of any commissioning team.
23 09 00 Instrumentation and Controls for HVAC- General
a. A majority of the existing temperature control systems within the facility are currently based upon the
Johnson Controls Metasys system. However, Johnson Controls, Siemens and CI3 are now approved TCCs at
the Hospital. However, there are locations where the required new systems of one TCC would work better
with the existing equipment than others. The Design Professional shall review such areas with the Owner’s
Rep.
b. The Design Professional shall coordinate all new temperature control work with any existing systems. - Temperature Control System Requirements
