Slide 2 Slide 3 Exterior of home is building envelope. Includes all components that separate indoors from outdoors. Prevent heat from being lost or gained inside home. Integral part of structures waterproofing system. Slide 4 Foundation Thermal Envelope Slide 5 Hold up structure. Keep out groundwater. Keep out soil gases. Keep water vapor out. Keep heat in during winter. Slide 6 Non insulated concrete foundation is most basic. Heat loss from basement accounts for significant energy loss from a home. Apply rigid foam to exterior of foundation to provide thermal resistance and protect from environment (heaving of soil). Properly insulate interior of foundation. Slide 7 Exterior wall assembly. Airtight construction. Moisture management. Insulation. Windows and doors. Slide 8 Slide 9 Seal bottom plate of exterior walls. Caulk before installation. Caulk inside edge after installation. Slide 10 Seal rim joist. Spray foam rim. Seal between top plate and rim joist. Seal between rim joist and subfloor. Slide 11 Seal between door thresholds and subfloor. Seal window and exterior door rough openings. Use non-expanding latex based spray foam that will not pinch jambs or void warranties. Slide 12 Protect exterior wall assemblies from water intrusion. All exterior finishes leak. Complete, properly lapped, and drained moisture barrier beneath exterior finish. Install adequate roof overhangs. Divert water from house. Water collection for irrigation. Slide 13 Adequate amount of insulation. Proper installation. Slide 14 Allow light into home. Present a major source of heat loss. Present a major source of heat gain. Low-E glass coatings. Low conductance gas fillings. Argon Krypton Low-E and gas fillings about 5% of windows overall cost. Slide 15 Maintain intended function for intended life expectancy. Examples Roof overhangs Gutters Weather resistive barrier behind exterior finish. Enhanced foundation waterproofing. Proper flashing Slide 16 Airtight construction. Keep moisture out. Saves energy. Prolong lifespan of structure. Improved air quality. Slide 17 Green Building for Building Professionals National Association of Home Builders The NAHB University of Housing 1201 15 th Street, N.W.

Increase durability and reduce maintenance. Reuse materials. Use recycled content building materials. Recycle waste during construction. Use renewable and resource efficient materials. Use materials which can be recycled at end of their life span. Slide 21 19.2 and 24 on center spacing. Single top plate. Eliminate unnecessary framing at intersections. Size headers for actual load conditions. Eliminate bearing headers in non- bearing situations. Slide 22 Floor and roof trusses. Engineered Wood Products (EWP) Uses resources efficiently. Greater spans. Durable. Environmentally friendly. Slide 23 Plywood. Oriented strand board. Wood I-joists. Glue laminated lumber. Laminated veneer lumber. Parallel strand lumber. Finger-jointed studs. Timberstrand laminated strand lumber. Slide 24 Have top and bottom chord Typically laminated plywood or Solid lumber. Utilize center web Consist of oriented strands or Laminated plys of lumber Save lumber utilizing more material. Slide 25 Layers of dry wood veneers. Waterproof adhesive. Cured in a heated press. Grains run in same direction which makes a stronger framing member than conventional lumber. Slide 26 Use several shorter 2x4 or 2x6 sections of lumber. Reduce warping. Adds strength. Interchangeable with non-jointed lumber. Slide 27 Facility located in Deerwood, Minnesota. Oriented strand board product. Rim boards, columns, headers, and wall studs. Potential in window and door industry. Manufactured in 35x8x5 billet. Uses resin, steam, and pressure. Centered within 13-county area with adequate supply of aspen which reaches maturity in about 30 years. Slide 28 Insulated concrete forms (ICFs) Foam forms Air tightness, strength, sound, and insulation. Saves energy and money. Durability. www.forms.org Structurally insulated panels (SIPs) Floors, walls, and roofs Rigid foam sandwiched between layers of oriented strand board, plywood, or fiber cement. Framing, insulation, and exterior sheathing in one-piece component. www.sips.org Slide 29 Fiber-cement Vinyl Masonry products Metal All offer durable options which have increased life spans and can typically be recycled. Slide 30 Recycled content materials. Rapidly renewable materials. Reused or reclaimed materials. Composite materials. Slide 31 Recycled content pop bottle carpet. Yarn from polyester resins from recycled pop bottles. Composite decking. Wood fibers. Plastic grocery bags and milk jugs. Cellulose insulation. Recycled news print Cardboard fibers Computer papers Slide 32 Bamboo Durable flooring. Manufactured from bamboo which grows to heights of 40 and matures in less than 5 years. Neat grain patterns. Cork Slide 33 Reclaimed flooring. Reuse doors. Interior trims. Slide 34 Medium density fiberboard Cabinets Trims Doors Laminate flooring Slide 35 Reduce disposal cost. Eliminate waste before it starts. Recycle Cardboard Grind wood and drywall waste for erosion control. Metal Increase material efficiency. Reuse Cabinets Doors Flooring Trims Enhance marketing image. Market your efforts. Slide 36 Reduce materials with alternative methods. Recycle waste. Use resource efficient materials.
