21 The many window innovations available today require a designer to make selections in at least 16 different variables VARIABLES

22 10 1. GLASS THICKNESS 2.5, 3, 4, 5, 6, 8, 10, 12, 16, 19 mm

23 90 2. TINTS: Low-Iron Clear, Clear, Green, Blue-Green, Blue, Bronze, Light Grey, Grey, Dark Grey 9

24 COATINGS: Visible Absorbing Visible Reflective Visible Color (Gold) Low Emittance Solar Absorbing Solar Reflective Solar Transmitting Self-Cleaning Anti-Reflective Other (UV Block, Anti-Graffiti) 10

25 3, HOW MANY LIGHTS? Single Glazing Double Glazing Triple Glazing Add-On Panels 4

26 10, IG SPACER Aluminum, Partly Insulating, ‘Warm Edge’ 3

27 32, Gas Fill Air, Argon, Krypton 3

28 97, GLASS STRENGTH Annealed, Heat Strengthened, Tempered

29 8. IMPACT RESISTANCE Laminated 0.015” pvb Laminated 0.030” pvb Laminated 0.060” pvb Laminated 0.090” pvb Colour interlayer Impact Resistant Interlayer Acoustic Insulating Interlayer CIP (Cast in Place Epoxy Laminate) 8 777,600

30 9. LAMINATION ORIENTATION Coated plies: Coating to air side OR Coating against interlayer (pvb etc.) n.b. Low-E coatings touching the interlayer lose their low-e property because glass is opaque to Far IR! 2 1,555,200

34 93,312, ORIENTATION OF OUTER LIGHT 2

35 186,624, ORIENTATION OF INNER LIGHT 2

36 373,248, ORIENTATION OF IGU Everyone should use hand-held coating detector meters 2

37 That makes about millions different combinations! ONE is the best. All others are likely less than best. HOW DO YOU CHOOSE?

38 CONCLUSIONS Glazing choices are many and varied IG gas fills and some coatings (4 at least) are invisible You cannot see by eye: U-Factor or SHGC There are tools, codes, standards and certification programs available Which bring us to low e, energy savings, and green issues….

39 Glass for Malaysia How do you choose? Performance issues Look of the building Energy Savings Green initiatives Many, many factors

40 40 TECHNICAL INFORMATION

41 The 4 Energy/Heat Flows Remember: Heat Flows from Hot to Cold UV Visible Solar IR Far IR 3% 50% 47%

42 Heat Flows from HOT to COLD Conduction Convection Radiation

43 U-Factor measures the rate of heat transfer from warm air side to cool air side. Watts/sq.m.degC Far IR Radiation Convection Conduction

44 SHGCSolar Heat Gain Coefficient % of Sun’s heat striking a window that enters a room (by conduction + convection + radiation) Far IR Radiation Convection Solar IR Radiation

45 Shading Coefficient % of Sun’s heat striking a window that enters a room (by conduction + convection + radiation) Compared to % of Sun’s heat striking a 3 mm Clear Glass window that enters a room (by conduction + convection + radiation) SHGC ~ 0.87 x Shading Coefficient Shading Coefficient is a Poor # to use…Why? Whose 3mm glass? Why not 6mm? SHGC is a pure formula and preferred.

46 Heat enters when the sun shines through the glass: SHGC (Solar Heat Gain Coefficient) or SF or S/C About half as much enters over a 24 hour day by conduction (U-Factor, or K factor) for 15 °C difference (40 °C outside, 25 °C inside) Adding Low Emissivity always helps because it lowers SHGC and it lowers U-Factor

47 Three Numbers are needed: 1.Tdw for fading control. (Free from LBNL Windows 5 1 to 0. Lower means less fading. ) 2.SHGC for Solar Control (or SF or Shading Coefficient x 0.87 Lower value means less solar heat gained inside the building from sun shining on the window) 3.U-Factor for thermal control (or U-Value, K Factor. Conversion: 1Btu/hr.sq.ft.°F = 5.68 Watt/sq.m.°K Lower value means less heat flow by conduction from warm to cold)

48 WHAT TO DO: 1.Select Glass for appearance, daylight transmission, color, reflectivity, etc. 2. Add a Low Emissivity property, and add a light of glass, for better Solar control if a solar absorbing layer is present. 3. For better Thermal control add Low-E, and add a light of glass (double glazing)

49 Glass, Light, & Heat The Flow of Visible and Invisible (Infrared) Energy from the Sun. Energy is Either: Transmitted Glass Absorbed Reflected

50 Typical Glass Energy Characteristics 3mm monolithic CLEAR 8% 100% 6% Reflected Out 7% Absorbed (Emitted Out) Total Rejected 13% 86% Transmitted In 1% Absorbed (Emitted In ) 87% Total Admitted INDOOR OUTDOOR

51 Solar Spectrum Terms Visible Light Transmittance Infrared (IR) Percent of light in the visible spectrum transmitted through the glass Wavelength range of ~ nanometers Has a penetrating heat effect when radiated onto a transparent material. Short-wave IR converts to heat when absorbed by an object Wavelength of ~ nm Ultraviolet (UV) Invisible to the human eye. Partially responsible for fading fabric materials over time, etc.Wavelength of ~ nm
