Houses in cold climates usually should not have large picture windows? true or false?

It depends on the quality of the glass, the hours of daylight you'll recieve and the direction the window is facing.





In the northern hemisphere the Sun is found in the south direction of th esky. Therefore any south facing windows should be large to allow the Sun's radiation to penetrate. Obviously you need to recieve solar radiation to benefit. If you live in a densely poulated area with shadows cast over your windows then this would be pointless.





North facing windows will recieve no sunlight are therefore shouldn't be too large.





In the southern hemisphere the opposite is true. East and west facing windows will not be of any benefit since the solar radiation they recieve, if any in winter, will be very sparse.





However, glass can vary enormously in their thermal conductivity. Heat loss is normally measured by the thermal transmittance or U value, usually expressed in W/m^2K. In its most basic terms, the lower the U value, the greater the thermal insulation. Insulating glass units incorporating low emissivity glass can significantly improve the Thermal Insulation. Glass of higher U values will offer poorer insulation (http://www.pilkington.com/applications/p鈥?/a>





Obviously in winter the days are much shorter and any solar heating will be of a short (a few hours) duration. Windows will therefore lose heat as the Sun disappears over the horizon,Houses in cold climates usually should not have large picture windows? true or false?
False.. the bigger the window the more natural sunlight it will let in and help with the heating of it...Houses in cold climates usually should not have large picture windows? true or false?
True. A room with any window will always take more energy to heat than a room without windows, and the bigger the windows the more heat is needed.


When the sun is shining in the window, you may need less heat, but if you live in a cold climate you aren't going to get much sunlight. In a place like Chicago, in the winter, you only get sunlight for about 8 hours out of 24, and that's on a good day. And the sun is only going to hit your window for part of that time. The rest of the time heat is going out through the window faster than through the walls.
Plus, the real estate value of houses with tiny windows will nosedive, nevertheless.
I live in Chicago, I guess that's a cold climate, and my window is 7'x14' I think that would be considered large. It is a high-rise and it's special glass. With modern glass it is possible.
I think it is false. Just in my opinion, more sunlight would be let in if the windows were bigger and at night the chill would stay on the glass... my grandpa told me that... the bigger the better.
