Michael,
Yes and no. It is sometimes confusing, but I will try to explain, but first I will give you the link I found to Radiance as follows, http://www.radiancecomfort.com/ If you go to our site http://energysavingnow.com/ and read the introduction, you will also read about how the body function. Hot, warm and cold are descriptions of the human comfort, not necessary a specific air temperature, except for Architects, construction and HVAC engineers. Not only that, but it is a difference between men and women, in the sense that women have an extra layer of fat under the skin. Now I am going to be labelled as "male chauvinist", by the feminist movement, but I have to say it. The body is dependent of three major parameters, the radiation/emission, the air temperature and the humidity. The average brain with mentioned professions are limited to one parameter set, so we already here have a very large technical problem. Three environment descriptions, three energy transmission methods and the difference between men and women, not to mention between individuals. Who said that life is easy? In short, yes, the window you describe is very much better. Regardless of heat losses or not. Hakan At 10:12 03/01/2004, you wrote: >Thank you, Hakan.
