There is a little bit more to this topic than just the glass. House aspect is a major factor, yes some of these wonderful architecturally designed houses are full of glass, You might find they face the correct direction to warrent using all this glass, not just to capitolise on the views. Some of these houses intentionally leave as much sun as possible into the house in the morning to heat up the house, to increase passive solar gain in the house interior for the rest of the day. You might find that these glass walls (when they are in the wrong aspect)are covered overhead either with a major roof overhang, or shading device to cut out the sun when not required, reducing solar gain. You'll find is mandatory now for all dwellings to be compliant with Part J of the BCA, a major component of this Part J is filling out a Glazing calculator which determines if your house really does have too much glass in relation to the floor area. Lastly the BCA glazing calculator does not recognize 'drapes' as a solar control device. Hope this helps a bit, Pat.

Pat is right. I am only referring to glazing that is indiscriminate of aspect. Most people install glazing for aesthetic purposes or views rather than a method of controlling solar gain. Design with correct orientation, shading and combining with thermal mass can ensure that glazing provides energy efficiency rather than being an energy liability. A question.
