Climate
• Hot dry summers• Moderately cool winters• Annual sunshine: 85%• Diurnal temperature
swings are very large• Annual Precipitation: 7 in.• April-June are driest• August is wettest (1 in.)

Climate—Design Priorities
• Keep hot temperatures out during summer
• Protect from summer sun.
• Use evaporative cooling in the summer.
• Use thermal mass to reduce day-to-night temperature swings during summer.

Design Priorities
• Keep the heat in and cool temperatures out during the winter.
• Let the winter sun in.• Use natural ventilation
to cool in spring and fall.
