color=#0000ff size=2>Correct me if I'm wrong, but I think your
design building can vary from the 90.1 prescriptions (at least for the
ECB which is what I am assuming your using it for - give the design case
reference). For example if you use daylight sensors and you want to use a
lighter glass to take advantage of it, I think you can as long as there's an
overall energy savings - am I correct?</FONT></SPAN></DIV>

color=#0000ff size=2>Speaking of high performance glass - I am trying to model
PPG's Solarban 70, and it doesn't seem to be available in the window 5.2
database. (Its a new product with a 0.63 Tviz & 0.27 SHGC - a light to solar
gain ratio of 2.33). Is it possible to manipulate the numbers in Window 5.2? Is
the simplified glazing option acceptable for 90.1 ECB
analyses?</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=437263312-09042007><FONT face=Arial
color=#0000ff>International Glazing Database (IGDB), which is part of WINDOW 5.2
program (windows.lbl.gov) contains several hundred individual glass layers whose
solar transmittance is at or below 0.3, which, as a part of glazing system and
whole fenestration product, would produce SHGC of 0.25 or lower, which meets
ASHRAE 90.1 for all climate zones. The best choice for low SHGC windows is
so called spectrally selective low-e, and there are at least 100 glass
products with this type of low-e coating. The cost of these products is
only marginally higher than the cost of clear glass.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=437263312-09042007><FONT face=Arial
color=#0000ff>Having said that, I do want to state that the use of low SHGC
products in heating dominated climates (anything at or above climate zone 5) is
wrong and is the major flaw of both ASHRAE 90.1 and IECC 2006, particularly for
orientations with potentially high solar gain in the winter, such as South
orientation.</FONT></SPAN></DIV>
