Identify Your Climate
MIXED & HUMID- 3A, 4A, 5A

Mixed, humid climates experience all four seasons, however season length and level of extremity vary by location. These regions receive more than 20 inches of rain annually. The average winter temperature typically drops below 45° F during the winter and summers can be extremely hot and humid. Many of these regions will experience some snowfall and icing during winter months.

Buildings in these regions must be designed to balance conflicting weather conditions. Many mixed climates provide comfortable conditions during transition periods with very little intervention, but protection must be provided from seasonal extreme cold and heat. Adaptable features such as operable shutters or removable awnings can help adapt to seasonal needs. Solar control techniques should minimize direct solar gain during summer months, but with careful sun angle calculations, solar gain can be used in winter for passive heating. Sun angle can change drastically by season and must be considered year round. Similarly, layouts should take advantage of summer breezes, but provide protection form the harsh winter wind. Dehumidification and moisture control should be considered, as moisture will move in opposite directions based on the heating or cooling demand of the interior space.
