Review of Insulation-Chiras

(Olson and Schwartz)

Review of Glazing-Chiras

Window glazing:

South glass: 7-12% of floor footage

North glass: <=4%

East glass: <=4%

West glass: <=2%

Review of Glazing-Chiras

Review of Glazing-window insulation

OVERHANG p.107 (www.susdesign.com/overhang)

L = Length of Projection

H = Height of window opening

L = H / F44º latitude: F=2.0-2.7

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

INDIRECT WALL MASS: glazing >7% x 8.3

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.

Review of Indirect Gain Thermal Mass-Chiras

(Thermal storage or Trombe wall)

Vented Trombe wall

(Thermal storage or Trombe wall)

Review of Indirect Gain Principles-Chiras

Orient south +-10 degrees

High performance glass

Thermally isolate glass

High quality caulk

Use Selective surface or high temp paint

Use dense material

Minimal interior finish

Insulate glass at night

Direct + Indirect glazing = MAX 20% of floor area
