3 2030 Energy Initiative Changes in Building Industry Clean Energy & Security Act 2009 o 50% more efficient from o 5% each year after 2014 o 70% efficient by 2030 o Similar for nonresidential Pending federal legislation SIP s technology meets these guidelines

4 SIP Benefits to meet 2012 Energy Code Continuous insulation benefits for greater overall R-value Greater airtightness and less infiltration New Energy Code Requirements 2012 IECC 13% more efficient than 2009 and 30 more efficient than 2006 IECC Greater insulation requirements(continuous envelope) Blower door test a new requirement for new construction other than with SIP Construction

5 Energy Efficiency Energy efficiency is a key element of any green home or commercial building Buildings account for 40% of U.S. energy use Reduces carbon footprint Not green washing tested, verifiable benefits and payback

6 SIP History First used in 1930 s Forest Product Lab Still being used as a day care center Used skins to carry the structural loads Wall studs ¾ x 2 ½ Proven Technology

7 Structural Insulated Panels (SIPs) are Composites of: Oriented strand board (OSB) Regenerable Harvested Wood Expanded polystyrene (EPS) Recyclable Insulation Laminating adhesive Structural Grade

8 What is EPS? Closed cell thermal insulation Thermoplastic Free of CFCs, HCFCs, HFCs and formaldehyde Recyclable Warranted R-Value (4.17 per in.) No Thermal Drift 20 Year 100% R-Value Warranty

9 Other Forms of Insulation Urethane Has dangerous HFC s, CFC s Not dimensionally stable Diminishing R value Non recyclable Poly ISO, XPS Has dangerous HFC s, CFC s Diminishing R value

10 Why Treated EPS? Talon Guard from Atlas Treated EPS offers built-in resistance to termites & carpenter ants. 30 Year Warranty

11 SIP Coatings BluWood a lumber treatment Fungal protection Termite infestation protection No-Burn is a Class A fire retardant Clear coating Non toxic Non-carcinogenic Green properties Sto-Guard is a Secondary weather barrier Air & moisture barrier 6 Month exposure warranty

12 SIP s are Code Approved For over 30 years Recognized by these building authorities BOCA, ICBO, SBCCI, HUD ICC.ES PSC Various state and local agencies FL, TX, IL, et Each panel stamped with code listing

13 SIPs are Used For: The exterior insulation envelope of the building, including structural: Walls Roofs Floors

14 SIPs are Available in Various Sizes and Thicknesses Walls Panels R-Value at 40 F 4 1/ / Roof Panels R-Value at 40 F 8 1/ / / Panels are available up to size 8 x24.

15 Blocking Steel Large Spans

16 Attachment Options Into Steel Joist Into LVL or Dimensional Lumber

17 Screw Options - Uses Screws go through panels, into structure Wood screw point for wood Light drill points for metal light gauge Heavy drill point for steel/iron up to ¼ thick

18 Corner Wall Detail

19 SIP Roof Panels SIP roof systems are non-vented SIP Panel vs. vented attic space Jim Walter Research Corp., St. Petersburg, Florida Surface temperature only 10 degrees warmer Shingle manufactures will provide full warranty coverage for SIP s roof decks Architectural Grade/ 40 year warranty required

20 Roofing: Pre-cut end fill cap to finish off the roof. Panels and plates can also be miter cut to form the roof edge. Non-Vented

21 Load/Span Design Charts Load charts vary by spline and load type Block and surface spline chart Other spline types: I-joist, LVL, 2x lumber

22 Architectural/Design Flexibility Efficient custom designs Fire Stations Churches Restaurants Banks Schools Auditoriums Industrial Buildings Residential

23 Design Flexibility Timber frame Post and beam Timber trusses

31 Energy Code 2012 Thermal Bridging Stick Frame SIP

32 Life Cycle Analysis (LCA) studies for SIP s EPS Molders Association SIP s save energy invested in component and product manufacturing & transportation year energy payback year recapture of greenhouse gas emissions BASF SIP s outperform 2x construction for LCA Oregon Dept. of Environmental Quality SIP s reduce onsite construction waste when compared to other systems

33 Energy Code 2012 Oak Ridge National Laboratory Studies Less gaps to seal test room, is 15 times tighter than stick built 50-70% annual savings over MEC Framing factor: 3% vs % stick built

34 Sizes up to 8 x 24 Panels are lightweight, easy to handle Oversized panels may require mechanized equipment Building with SIPs

35 Building with SIPs Panel Fastening: Nails Staples Screw fasteners Adhesive/ Sealant

36 Wall panels have 1-1-1/2 diameter electrical chases Horizontal at switch & outlet height Vertical at 4 o.c. SIP s and Electrical Top and bottom plates are drilled during installation to access the vertical electrical chases

37 Building with SIPs Foundation types: Slab on grade Poured concrete Concrete block Pre-cast concrete Insulated treated wood

38 Wall to Foundation Detail

39 Wall to Rim Joist between Wall Panel and Foundation

40 Building with SIPs Platform framing: Set plates back from floor s edge Attach plate to floor with adhesive/sealant and fasteners At corners, position plates to allow for adjoining panels

41 Building with SIPs Splines: Used to connect panels Eliminate thermal breaks Factory cut, sized to match pre-cut spline pockets Plates: Used to block panel edges Plate pockets precut in panels

42 Block Spline Detail

43 Roofing: Larger panels can be supplied for increased efficiency in roof assembly

44 Requires Basic Stick Frame Tools

45 Cost Comparison How much does SIP quality and performance cost? Materials: plus 10-25% Labor: minus 30-40%

46 Utility costs have been proven to be as much as 50-60% Less in a SIP Building than a conventionally-built structure.

47 Energy Code 2012 Air filtration part of performance method calculation Responsible for 30 50% of heating and cooling loss

48 Cost Comparison Comparable construction costs with Long-term Energy savings Philip Merrill Environmental Center LEED Platinum This is 59.0% less than typical office buildings based on 1995 data collected by the Energy Information Administration.

49 SIP panels are thoroughly tested and proven for structural and thermal performance SIPs Review

50 SIPs Review Structural load bearing: Transverse Axial Creep Racking Diaphragm

51 SIPs Review Long span capacity: Roofs/ceilings

52 Speed of Construction Field experience indicates building with SIPs is approximately 30% to 40% faster

53 SIPs Review Comfort features: Energy-efficient Eliminates air movement Rigid EPS core No thermal drift Termite resistant

54 Building responsibly reduces the environmental impact Lower energy consumption Recyclable cores Generable wood No CFCs, HCFCs or HFCs Energy Star PATH FSC Chain of Custody
