Separate names with a comma.
It is my understanding that the robustness of mounting hardware is driven by UPWARD forces (i.e. wind) and LOADS (e.g. snow), lighter panels don't...
I had a similar problem (though mine was ICE!). Thank for the info, I will see if I have a crack as well.
While nice to have more efficient cells, for the most part the market is being driven by $/watt. Additionally, we are at the point where balance...
Right. I was talking about removing the cans altogether. The LED fixtures I was talking about, mount directly to the ceiling and are only about...
One instance where LEDs *really* make a lot of sense over CFLs is in recessed can lights. These are usually horrible air leaks, they can't in...
I would rather keep my balls on my person, than in my garage... As always YMMV. :-)
The way to become energy independent (and still remain on oil as these people seem to want) is to consume less oil by percentage with the rest of...
Jeweler's Rouge? :) :rolleyes:
It could well be that society (in whatever guise) will decide that this is exactly where we need them. Cars that can negotiate rights of way...
Please don't write it like that. Yes, you got it right, and I knew what you meant. Two panes is 0.85 * 0.85 = 0.7225 Thanks.
The sun-room is not heated space. Unless you *care* that is is 40° instead of 30°, the heat that ends up trapped there (when it is cold) doesn't...
Ok. Time to explain Lo-e. Lo-e stands for Low Emissivity. Emissivity is a measure of the percentage of radiant energy given of by a surface at...
No one. That is a generic window, from my spreadsheet. And again, it is glass only, actual windows with frames will differ.
Yes, Coatings are often only on one surface of one piece of glass, regardless of number of panes. There are some double coated triple panes,...
Sorry guys, you seem well on your way, and I am busy writing a paper for a local passivhaus forum, so I can't pay complete attention here. Just...
Sure. Things get tricky when you start adding coatings, etc. For example the difference between soft-coat lo-e and hard-coat lo-e, is very...
A window with a U value of 0.3 (R = 3.3) will lose 0.3 * 6890 Heating Degree Days (HDD) = 2067 BTUs / ft^2 / year, of heat loss. HDD is for...
SHGC is percentage of possible solar heat transmitted. Clear glass has SHGC of about 0.85 US made double pane lo-e windows have a SHGC of...
