Architectural Design Basement Floor Black band lives here! Features Utilities Water Storage Semi-finished rec. room/storage space

Architectural Design First Floor Black band lives here! Features Open kitchen/living room/dining room 1 Guest bedroom/office (pictured as an office) 1 Half bath Approximately 1200ft 2

Architectural Design Second Floor Black band lives here! Features 1 Master Bedroom (~330ft 2 ) -Full bath attached 1 Bedroom (~210ft 2 ) 1 Separate full bath Approximately 1000ft 2

Structural Design Considerations Black band lives here! Maintain a factor of safety between 4 and 6 Utilize green materials wherever possible Design with use of common off-the-shelf items in mind Design to include 2ft overhang Attempt to achieve greatest strength and durability with the lowest possible cost and maintenance potential

Structural Design Truss Design Options Black band lives here! Fink (W) – Spans 16’-33’ Howe (K) – Spans 24’-36’ Double Fan – Spans 30’-36’

Black band lives here! Ponderosa Pine -Dimensionally Stable -Good strength -Workable, resists splitting Douglas Fir -Superior Strength-to-weight ratio -Dimensionally stable -Excellent nail and plate holding ability Hem-Fir -Nearly as strong as Douglas Fir -Preferred for aesthetically oriented applications Steel -1/2 to 1/3 the weight of wood -Superior strength/durability -Non-combustible -May require outside engineering Structural Design Truss Material Options

Black band lives here! Asphalt Shingles -Most popular option -Low cost, great value -Usually guaranteed years Wood Shingles -Aesthetically pleasing -Expensive -Require maintenance Slate -Aesthetically pleasing -Very durable -Very heavy, expensive Metal -Durable, low maintenance -Range from cheap and utilitarian to expensive and ornate -Simple installation Structural Design Roofing Material Options

Black band lives here! Structural Design Next Steps Determine design and materials to be used based on feedback from other engineers’ calculations Complete structural analysis of the roof system to accommodate the 4 to 6 FOS Finalize design and compile a BOM

House Elevation Black band lives here! Elevation Limit 15 Degree’s Per Boise, ID, Building Codes Windows: If desired in basement, approximately 1 in 2 per 100 ft 2 of house footage on buried perimeter.

Foundation Analysis Hydrostatic Pressure Black band lives here! Three Backfill Options Modeled as Liquids were Sand, Pea Gravel, and Soil SandPea GravelDirt/Soil ρ (lb/ft 3 ) 100 ρ (lb/ft3) 110 ρ (lb/ft3) 120 Depth (ft) F H (lb/ft2) Depth (Ft) F H (lb/ft2) Depth (Ft) F H (lb/ft 2 )

Foundation Analysis Support Area and Stress Black band lives here! Stress is the total weight of the house on the foundation over the area that supports the foundation. The following assumptions were made: 1 st Floor: 60 lbs/ft 2 2 nd Floor: 40 lbs/ft 2 Roof: 30 lbs/ft 2 Resulted in an overall stress of approximately 3500 lbs/ft 2 being applied to the foundation.

Foundation Analysis Factor of Safety Black band lives here! The factor of safety was calculated using the stress and compressive strength, as well as the reaction forces and bending moment. Multiple compressive strengths of concrete were also tested from 3000 to 4500 psi. Range of Factor of Safety’s: 4.10 to 5.35 These are all with an acceptable range for the construction of a house

Foundation Analysis Diagrams Black band lives here! Tension: Occurs on inside of basement Compression: Occurs at site of soil pressure (Outside of Wall)

Building Thermal Systems Heat Transfer Analysis Drywall materials have very similar thermal properties. Plywood is standard Siding is less a thermal issue and more a matter of aesthetics Black band lives here!

Building Thermal Systems Heat Transfer Analysis Assumptions Natural and Environmental convections are small and will be calculated. Ceiling and Basement floor were modeled as walls, will have higher resistance Radiation effects unknown Black band lives here!

Building Thermal Systems Heat Transfer Analysis Results: 2x6 UA value ≈500 BTU/ft F 2x4 UA value ≈580 BTU/ft F Values are with fiberglass, drops ≈50 BTU/ft F with formed plastics Black band lives here!

Building Thermal Systems Heat Transfer Analysis Variances: 1.) Standard wall thickness is either 2x4 or 2x6. 2.) Insulations are Cellulose (or equivalent), formed plastics or sprayed fibers. 3.) Windows can be Single- Double- or Triple- layered Black band lives here!
