Energy Efficient Outdoor Shades or Lattice for Privacy

Window Shade

• Outdoor shade structures can block light to a home's windows to reduce summer cooling costs. South- and west-facing windows can be sources of overheating in the summer and can create uncomfortable glare in the room. A properly placed shade structure will cut down on glare and unwanted solar heat without obstructing views out of the window. A shade structure can even improve the view from inside by adding texture and greenery.

Outdoor Room

• A shade structure can improve the interior environment by shading windows, but it can also be a part of an outdoor room with a ceiling and one or more walls that can extend your living area through much of the year. The structure can create a microclimate that's more comfortable than the surrounding area. In summer, it will be cooler because of the shade and natural ventilation. In spring and fall, the space may be warmer than the outdoors if it's well sheltered by the home and by strategically placed vegetation. Additionally, a low angle sun can penetrate the space to warm it.

Transition Space

• If the shaded space is a porch or patio extending from the home, it creates a transition area from inside to outside. The space adds a layer of privacy that's particularly nice for the street side of the home. It acts as a buffer zone between the home and the street, increasing privacy for people entering and leaving through the front door. Additionally, the space provides an opportunity for engaging with the community and neighbors from a protected, yet semi-public space.

Adding Vegetation

• A shade lattice can be beautiful in itself, but the addition of climbing vines adds a layer of functionality as well as aesthetic appeal to the structure. Some shade structures--such as louvered designs--provide optimal shade without vegetation. However, there are benefits to using vegetation on a more open lattice to provide shade. The plants create a cool and humid microclimate, making the space inviting on hot summer days. In summer, the vines leaf out to provide shade; in winter, they allow more sun into the space for additional warmth.
