Passive Heating & Cooling Systems

Came across a few articles in my searches for passive heating & cooling systems. Most suggested that for tropical climates (i.e KAKADU) cross flow ventilation is a must. Currently reading up on some works by architectural firms that build in Miami, Florida. Miami is a good commercial location to look for ideas as they have extremely hot days coupled with humidity at above 50% everyday.

One site offered some advice in terms of the use of roof angled glazing:

NEVER USE ROOF ANGLED GLASS ! ! !



(1) Roof-angled glass is a huge heat loser on winter nights, when warm air rises to touch the low-thermal-resistance highly-conductive glass. It is like a thermal hole in your ceiling and roof, allowing enormous, expensive heat flow.

(2) Roof-angled glass is also a huge heat gainer on hot sunny summer days, when the scorching sun is nearly straight overhead for hours.

  1. Heating systems keep your home warm and comfortable. If you live in a particularly cold climate, the function of your heating system is a high priority.
