  1. CDAE 170 Solar Building Strategies Class #7 Oct. 18, 2003 Gary Flomenhoft BSME, MAPP, CEE Research Associate Gund Institute, SNR

  2. Review of Glazing-Chiras Window glazing: South glass: 7-12% of floor footage North glass: <=4% East glass: <=4% West glass: <=2%

  3. Direct Gain Principles-Kachadorian East, South and West glass should be 10-20% of total exterior heated wall area Peak supplied February day increase in solar slab temperature should be 8 degrees.

  4. Review of Indirect Gain Thermal Mass-Chiras (Thermal storage or Trombe wall) Vented Trombe wall

  5. Sunspace

  6. Skylight

  7. OVERHANG

  8. OVERHANG p.107 (www.susdesign.com/overhang) L = Length of Projection H = Height of window opening L = H / F 44º latitude: F=2.0-2.7

  9. SHADING

  10. Vapor Barrier

  11. INSULATION VALUES

  12. Review of Direct Gain Thermal Mass-Chiras Sun-tempered = 7% of floor footage. Incidental mass takes care of it (sheetrock, framing, furniture) >7% glazing needs extra mass. MASS THICKNESS 4-6” DIRECT FLOOR MASS: Each square foot of glazing over 7% x 5.5 or INDIRECT FLOOR MASS: glazing >7%sq.ft. x 40 or DIRECT or INDIRECT WALL MASS* in solar room: glazing >7% x 8.3 *Not everyone agrees

  13. Review of Indirect Gain Thermal Mass-Chiras (Thermal storage or Trombe wall)

  14. ENERGY COSTS
