10. Windows & Doors

11. Openings: • Windows and doors • Major impact on the house’s • appearance • Many Style options

12. Windows and Doors: Major part of …. • The comfort / safety of the house • Energy performance of the house • Many of them (Multiples) with variables = Scheduled

13. Windows & Doors Doors - Labeled on plans with number inside circle Windows – Labeled on plans with letter inside octagon or triangle …Labels refers back to a schedule

15. Window Sections Typical Section details Head (top) Jamb (side) Sill (base) R.O. (ROUGH OPNG.) F.O. (FINISH OPNG.)

20. Window Schedule • Size 6040 = 6’ W x 4’ L • (or hgt.) • Type - Operation • Glazing – glass type • Material – frame type

21. Window Schedule

25. WINDOWS 4 Ways to Evaluate • U-FACTOR • Solar Heat Gain Coefficient • Visible Transmittance • Air Leakage

26. U-FACTOR U-FACTOR The rate of heat loss is indicated in terms of the U-Factor of a window assembly. The insulating value is indicated by the R-Value which is the inverse of the U-Value. The lower the U-Value the greater a windows resistance to heat flow and the better the insulating value.

27. Solar Heat Gain COEFFICIENT The SHGC is the fraction of incident solar radiation admitted through a window. SHGC is expressed as a number between 0 and 1. The lower a windows solar heat gain coefficient, the less solar heat it transmits.

28. VisibleTransmittance The visible transmittance is an optical property that indicates the amount of visible light transmitted. Theoretical values vary between 0 and 1, but most values are between 0.3 and 0.8

29. Air Leakage Heat loss and gain occur by infiltration through cracks in the window assembly. Air leakage is expressed in cubic feet of air passing through a square foot of window area. .3 is recommended for Oregon

30. Low-E Windows • Glass is coated with silver or tin oxide which allows visible light to pass through but reflects infrared heat radiation back into the room. • Reduces heat loss in cool climates • Allows visible light to pass through but reflects infrared heat radiation away from the room, admits up to 40% less radiant heat from the sun. • Reduces heat gain in warm climates

31. High number for cold climate. Low number for warm climates The lower the number the better the insulating value Varies from 0 to 1.0 The higher the # the more light is transmitted. The best windows have air leakage rating between 0.1 and 0.6 cfm/ft.

32. Single-Glazed with Clear Glass

33. Single-Glazed with Bronze or Gray Tinted Glass

34. Double-Glazed with High Solar Gain Low-E Glass, Argon/Krypton Gas

35. Triple-Glazed** with Moderate Solar Gain Low-E Glass, Argon/Krypton Gas
