The position of the sun is expressed in altitude (or elevation) and azimuth, both of which will vary by location, time of day, and time of year. Altitude refers to the height of the sun over the horizon (higher in …
Which trees provide the "best" shade in summer?
It’s true, not all tree shade is created equal. Broad-leaved, deciduous trees, in general, cast a broader shadow than many evergreens, such as pine species. This is due, in part, to the shape of the mature tree canopy. When grown …
Where can I find information about trees I can plant for energy conservation?
Most states have information to help you decide what trees are right for your location and planting conditions. In Maryland, for example, and many other states you can view nursery catalogs and order trees online from state professionals. The …
Are pine trees a good option for planting around my home for energy conservation?
All pine species have evergreen needles and grow seed cones; however, pine species vary considerably in where they are found, how big they get, and how fast they grow. Therefore, pine species also vary in their potential for energy conservation …
Which trees are recommended for maximum energy conservation?
For most aspects of energy conservation, the bigger the tree the better. Larger trees shade larger areas. Though not an energy-saving feature, large trees also store more carbon. In some ways, trees that use more water save more energy too, …
Do urban forests play a role in mitigating global climate change?
Urban trees play a role in reducing atmospheric carbon dioxide directly by storing carbon in the trunk, branches, roots, and leaves until these tree parts die and decay. Trees also reduce energy consumption by shading the sun, cooling the air, …
How can I measure the dollar value (benefits) of the tree in my yard?
There are several methods to measure the value of trees. The National Tree Benefit Calculator is a fast and simple way to estimate the benefits gained from your trees — for free. Just enter your zip code, the species, size. …
What are some effects of urban vegetation on urban climate and hot cities?
The presence and/or lack of vegetation can affect solar radiation, air movement, and air temperature. Vegetation may be used to intercept solar radiation directly by providing shade and also indirectly by covering surfaces that reflect or re-radiate solar radiation. Vegetation …
How does vegetation guide wind to maximize cooling in the summer months?
Strategically positioning vegetation in the landscape can maximize cooling in summer months and help protect from cold winds in the winter. Wind may be accelerated &/or, to some extent, directed by the use of strategically placed trees and other vegetation …
Trees for energy conservation and solar panels – are they compatible?
Trees help conserve energy in three primary ways: casting shade to keep buildings cool, blocking chilly winds to keep buildings warm, and transpiring (evaporating) water to decrease ambient air temperature. Obviously, trees casting shade onto buildings affixed with solar panels …
