| 03/13/2014 | RONALD BROWN | BUILDING-COMMERCIAL | REVIEW | Approved | |
| 03/24/2014 | ROBERT SHERRY | MECHANICAL-COMMERCIAL | REVIEW | Denied | 1. Comment not addressed. [Initial comment: Complete the Envelope Compliance Certificate by checking the appropriate line items in Section 3, the Air Leakage, Component Certification, and Vapor Retarder Requirements. Supporting documentation shall be either on the drawings or in a project manual. Sign the completed Envelope Compliance Certificate.] 2. Simply specifying the use of an "Ecobee" control system does not address the initial comment. Indicate which code-required features are to be included in the control system. [Initial comment: Show that the features of the proposed HVAC control system meet the control requirements of Sections C403.2.4 and C403.3 by providing for off-hour and set-back control, automatic shutdown and start-up control, and, if the control does not require manual changeover from the heating and cooling modes, restricts set point overlap.] 3. The ventilation calculations refer to a value as "Vcp" - what is the meaning of this symbol? Show how an "Ez" value of 0.85 was obtained. Include ventilation for the corridors. [Initial comment: Provide calculations demonstrating adequate ventilation using the current code. The City of Tucson did not adopt ASHRAE 62.1-2010 and the 2012 IMC only references Appendix A of ASHRAE 62.1-2010 as an alternate method of calculating the system ventilation efficiency (Ev). Reference: Section 403.2, IMC 2012. 4. Show how the diversity was determined for HP-2. [Initial comment: Both HP-1 and HP-2 (also referred to as AC-1, FC-1, AC-2, and FC-2) serve multiple zones. Calculate the system outdoor intake flow rate (Vot) using Sections 403.3.2.3.1 through 403.3.2.3.4, IMC 2012.] |
