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
An NFRC glazing system energy performance label will report U-factor, solar heat gain coefficient, visible transmittance, and air leakage; if the window is ENERGY certified, the ENERGY STAR label will be located next to the NFRC label
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
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
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 - This house has key features to block heat such as such as tree shading for the west wall and roof, minimized west-facing windows, and a porch roof, floor, and wing walls creating deep architectural overhangs and fins to shade south-facing windows
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
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
The patio roof on this home provides full shade to large glass doors and windows, reducing the home's heat gains.
Image
The south face of this home has an overhanging second floor, a pergola, and a roof eave to provide effective window and door shading for both floors in the summer without blocking view, diffuse daylighting, breezes, or ingress/egress
