That makes about millions different combinations! ONE is the best. All others are likely less than best.

HOW DO YOU CHOOSE?

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….

Glass for Malaysia

• How do you choose?

• Performance issues

• Look of the building

• Energy Savings

• Green initiatives

• Many, many factors

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.

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

Three Numbers are needed:

1.Tdw for fading control. (Free from LBNL Windows 5

http://windows.lbl.gov/software 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.°KLower value means less heat flow by conduction from warm to cold)

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)

How Low-E Coating Works

Low-E coating redirect radiant heat (long wave radiation) back toward the source

Heat moves from HOT COLD

In the Winter heat from the inside flows OUT

In the Summer heat from the outside flows IN

62

Low Emissivity = Low U-Value

In Winter, inside heat flows Out

In Summer, heat from the outside flows In
