solar heating, daylighting, and natural cooling.
Open floor plans encourage natural air flow, which
provides cross ventilation and evenly distributed heating.
Roof overhangs and deciduous trees shade walls in summer
while allowing sunlight to enter and warm homes in winter.
Certain building materials can also contribute to passively
heating homes in the winter. For example, brick, rock, stone,
concrete and other masonry or earthen materials absorb
heat of sunny winter day and then release that heat during
darker, colder times. Keeping the home shaded from the
sun during hot periods of the year results in the internal
