In extreme climates, construction decisions may substantially mitigate very cold or very hot weather conditions. A green contractor should address the following:
Will home orientation be considered? The orientation of the home can maximize or reduce window exposure. In hot climates, for example, less window exposure is better for keeping the home cool during the summer.
What sort of roof is recommended? The pitch, or slope, of a roof can impact energy efficiency. High-pitched roofs, or those with greater slants, are better in cold climates. For hot climates, low-pitch and reflective materials may be best for reducing heat.
What's the best ceiling height for this climate? Generally, it's lower for cold, higher for hot. The lower roof allows rooms to be heated more efficiently, and higher roofs increase air flow for better cooling.
