4. NSA Component Testing Guideline
Document is “complete”
Living document, under continuous improvement
Certain sections may benefit from expansion
Use of the document will help identify areas for improvement
Will be available on Member’s Only section of website or on NSA SVO

5. Report of ICC Hearings 2012 IBC, IRC, IECC, Etc.
Planned publication in April 2011
Adoption / implementation depends on local municipality
Currently, as of most states have adopted I- codes statewide
Non-ICC Code -
2000 IBC – 2 States (MO, NE)
2003 IBC – 3 States (CT, KS, SD)
2006 IBC – 25 (includes DC)
2009 IBC – 21
2012 IBC – 0

6. Report of ICC Hearings Changes of Interest Adoption of ASCE 7-10
General
40% bigger than previous, reportedly due to larger font
Occupancy Category now called Risk Category
Performance based design procedures included
Wind
Multiple wind maps with occupancy importance incorporated  Strength design wind speeds, therefore ASD load factor = 0.60
New simplified wind procedure in ASCE 7
IBC will also retain the Alternate All-Heights provision
Seismic
New maps

7. ICC / State Codes & Standards Update
Monitoring State Building / Energy Codes
Example: State of North Carolina Energy Code
2012 code was going to raise the sunroom roof and wall insulation from R-19  R-24 in CZ 1-4 and from R-24  R-30 in CZ 5-8.
In order to monitor the ICC model code, as well as national energy codes (IECC, ASHRAE 90.1, 90.2, IgCC, LEED, etc.) we have not focused on the individual state codes
In order to take on this task it would help to have a list of high-priority states

12. Sunroom Foundation & Deck Design Guide
Develop a design guide for NSA member company engineers, third party engineers and contractors to show the most common solutions to sunroom concrete foundation and wood deck design. Several example designs for each scenario would be presented including:
TEK 1: Concrete Sunroom Foundations
Site Soil Conditions / Testing
Slab on grade design – existing / new
Footing design
TEK 2: Deck Design with Sunrooms
PT lumber issues
Joist ./ Ledger / Carrier Beams / Posts / Bracing / Connections
Designing Footings for applied sunroom loads
NSA Engineering Services Report

13. Sunroom Environmental Load Examples
Develop example calculations for NSA member company engineers, third party engineers and contractors to show them the correct way to determine the ASCE 7 snow, wind, seismic and other loads on sunroom structures.
