These folding louvered porch doors provide effective shade from low-angle east and west sunlight and can open for views; the photovoltaic panels overhead allow in filtered natural light
Image
Image
Clerestory windows bring light in from above, reflecting it off of surfaces, making it more appealing than the direct light that comes from skylights
Image
Image
Exterior shading devices such as awnings or overhangs can significantly reduce cooling loads
Image
Infrared photometry shows the impact of a roof overhang on the south façade of a home, where the unshaded patio stonework is significantly hotter than the shaded portions of the patio and wall surfaces (temperature scale shown is in Celsius).
Image
Light-colored roofs and walls and deep overhangs for shade are some of the features used by builders in the hot-humid climate (Source: Alys Beach Construction).
Image
Low perimeter to area (P/A) ratio home designs reduce heat transfer and perform better in hot climate zones than high P/A ratio homes.
Image
Multi-layer honeycomb cellular shades such as these can provide summertime energy savings by blocking and reflecting solar heat, as well as wintertime energy savings by providing added insulation.
Image
Porch roofs, pergolas, and large overhangs can effectively shade windows and doors facing south, southeast, southwest, or even due east or west for most of the day if the overhang is very deep and sufficiently wide.
Image
Right – Horizontal overhangs on this house block sunlight in the summer while allowing it in during winter
Image
Right – This model home for the Solar Decathlon competition incorporates vertical trellises and retractable exterior blinds to control solar heat gain.
Image
Sheer shades can provide very effective daylighting and glare control while maintaining a softened view to the outside
Image
Temperatures in deep undisturbed soil at a given location are approximately equal to the annual average air temperature for that location
Image
The design of this home incorporates multiple methods to reduce summertime solar gains including roll-down exterior blinds, wide exterior horizontal louvers, minimized east/west-facing windows, and vegetation.
Image
White walls and roofs; overhangs and awnings; and operable shutters and garden walls all help to keep out unwanted solar heat gain providing cool interiors for this Florida home.
