Design tips for a hot dry summer
	climate with cool winter

Use design tips for a hot dry summer climate with mild winter, plus

Because of the large difference between summer and winter temperatures:

• Adjustable shading) to allow entry to winter sun, but keep out sun in summer (use shutters and external awning blinds on windows or hanging from verandahs);
• Solar pergolas, on the north side of the house - these allow sun penetration in winter but not summer;
• Deciduous trees and vines around the house, if water supply permits, will provide summer shade and allow solar access in winter.

Because winter is cold:

• Windows (north-facing) should be larger than for the hot dry climate with mild winter, to allow solar passive heating in winter;
• Bulk insulation is required to reduce heat loss through walls and ceilings;
• As in the other hot dry climate zone, bedrooms should be of lighter construction, so they cool quickly at night - the trade-off is that they will be cold on winter nights.
• Air-tight construction to reduce heat loss via drafts
