2012 Slide Template 3/31/2017 Chapter 3 General Requirements Label or Table Solutions National Fenestration Rating Council Component Modeling Approach (CMA) for site-built commercial windows. Field Labeling available for missing labels. How it typically goes is I am notified of a missing label. I take the job information and direct the manufacturer to follow the field labeling process. They work through the process as prescribed, document it with their inspection agency (IA), and I confirm with the job person if all went as planned. All NFRC participating manufacturers must follow this process per this NFRC document: See section Bob the Builder contacts you and says “I removed the labels.” You get the job information and contact the manufacturer. Than manufacturer does whatever is in the 118 pages you just sent. If you could flesh this out with a few bullet points, so that an AHJ could know what to expect and how to verify, that would help. What information will be included? How can an inspector know that it is genuine? What kind of timeframe? What is the cost? 2012 IECC Update Handout page 5 Copyright 2011 International Code Council

Explain conditioned space and how it affects residential and commercial buildings? Conditioned space is an area or room within a building being heated or cooled, containing uninsulated ducts, or with a fixed opening directly into an adjacent conditioned space. For residential buildings access doors from conditioned spaces to unconditioned spaces shall be weatherstripped and insulated to a level equivalent to the insulation on the surrounding surfaces (see Section R ). All sunrooms enclosing conditioned space shall meet the fenestration requirements of this code unless they meet exceptions (see Section R ). For commercial buildings the floor (see Section C ), duct and plenum insulation and sealing (see Section C ) are affected if the space is not conditioned. 2012 IECC Update Handout page 22

Explain the differences between service hot water systems and circulating hot water systems. Service water-heating is the supply of hot water for purposes other than comfort heating. Circulating hot water system is when the distribution piping is heated to maintain usage temperatures using pipe heating cable, the system pump or heat trace cable that has automatic or manual switches or controls that can be set to optimize system operation or turn off the system during periods of reduced demand. 2012 IECC Update Handout page 22
