"But Connecticut was paying up to $5 a watt for investments in energy efficiency," he continued, and a landed system, with greater exposure to sun than the partly shaded roof, though twice the price, offered twice the efficiency.
For example, a neighbor of the Antonios' son wanted to install a system on his house in Carroll Gardens, Brooklyn, but could not because the city would not let him prune the tall trees shading his roof.
Inside, the Tourer includes an eight-inch central information display and a shade roof panel not unlike the Magic Sky Control feature from Mercedes-Benz, which allows push-button control of the roof's opacity.
The danger is that the Vietnamese will turn their unique capital of tree-lined streets shading tile roofs into a second Bangkok--a forest of skyscrapers, a crawl of traffic, and an environmental catastrophe.
This is demonstrated in the paper using a parametrically defined model of a complex roof shading system based on the Changi Airport Terminal 3 design.
The method is based on an algorithm that calculates the optimum tilt and azimuth angles of PV modules on the basis of estimated data for solar irradiance, PV module shading times and roof characteristics.
The Picnic has laid down roots with a big, steel-and-concrete "roof" shading the picnic tables.
The four measures selected for uplifting the energy performance of the building envelope include glazing type, window-to-wall ratio, sun shading and roof strategies.
Greenhouses, particularly flat shading structures and curved roof houses, are often clad in permeable shade or insect-proof netting in southern Europe to reduce solar radiation gain and to increase ventilation.
