The design strategies appropriate to a given building depend heavily on its climate. There is no universal solution. What works brilliantly in an arid high-desert environment may be actively harmful in a humid tropical one. The first task of any designer is to understand the climate they are designing for.
Climate zones are typically characterized by temperature range, humidity, and precipitation patterns. For design purposes, the most useful classification divides the world’s inhabited climates into five broad types:
Hot and Humid (Tropical)— High temperatures year-round combined with high humidity and rainfall. Design priority: maximize ventilation and shade, minimize thermal mass, keep moisture out of the building fabric. Traditional responses include raised floors, open walls, large roof overhangs, and orientation for cross-ventilation.
Warm and Humid (Subtropical)— Hot humid summers and mild winters. Design priority: summer cooling through ventilation and shading, modest winter heating through passive solar and some thermal mass. Traditional responses include covered porches, operable shutters, and deciduous shade trees on the south and west.
Temperate (Mixed)— Moderate temperatures with cold winters and warm summers. Both heating and cooling are needed. Design priority: passive solar heating in winter with good insulation, natural ventilation cooling in summer. Thermal mass works well in this zone when properly managed.
Arid (Hot-Dry and Cold-Dry)— Low humidity, wide diurnal temperature swings (hot days, cool nights), and limited precipitation. This is the climate Pangea works in most often in Taos, New Mexico. Design priority: very high thermal mass to absorb daytime heat and release it at night, excellent insulation, maximum passive solar gain in winter, evaporative cooling in summer. Earth building materials (adobe, rammed earth, tire walls) are ideally suited to this climate.
Cold (Subarctic and Alpine)— Long, severe winters and short summers. Design priority: maximum insulation, minimal surface area relative to volume, aggressive passive solar gain, high thermal mass, and very tight building envelopes. Below-grade construction and earth sheltering are highly effective in this zone.
Understanding which climate zone you are in is the first step. The next is understanding the specific microclimate of your site: local wind patterns, topographic effects, shade from adjacent vegetation or terrain, and the specific behavior of sun and rain at your location and elevation. Climate zone descriptions are broad generalizations; sites within the same climate zone can vary significantly in their conditions.
