Plan review for the above referenced structure has been completed. This letter reflects comments to be addressed. In order to facilitate a shorter back check time, we request that you please provide revised plans and calculations, highlighting any changes, along with a written response to each of the noted items indicating action taken.

SCOPE OF REVIEW:
The scope of this plan review covers architectural, plumbing, mechanical, energy conservation and electrical. All code references are to the 2006 International Residential Code, 2006 International Energy Conservation Code, and Arizona State amendments to the 2006 Uniform Plumbing Code. All features were checked only to the extent allowed by the submittals provided. All portions of this project are assumed to meet or will meet other departmental requirements, conditions and concerns before permit approval.

GENERAL REQUIREMENTS:
All corrections and revisions shall be made on original tracings or a finished reproducible set. Return two sets along with a set of the first submission for reference. Pen or pencil corrections on final prints will not be acceptable. To avoid delays, ensure that all corrections have been made, are complete, and have been coordinated on all applicable detail and note sheets (clouded revision notation is not necessary for comment changes).

All engineers and architects involved in the design of the structure are to seal the related sheets of plans, details and calculations in accordance with the rules of the State Board of Technical Registration.

Show the "R" values of insulation and the "U" factors of the windows and doors on the plans as well as the solar heat gain coefficient SHGC minimum value of 0.40, N1101.2.
2. Tucson is in climate zone 2B. The simplified prescribed energy values for glazing and skylights is U=0.75, ceiling R=30 and walls R=13. Mass wall requirement is R=4 when 50% of insulation is exterior and R=6 when applied interior, N1102.1. RES check may be used for calculating compliance with other values. Select the location of Pima County rather than Pima (City). "Pima, AZ: 2006 IECC <4,000 ft" is found at the end of the list for the State selection. (Do not select Arizona).
