There are many advancements in building materials that assist in
saving money and energy. Though research on this topic was initially
launched for energy preservation purposes, it also helps in saving money
as well as preserving environment.
U.S. Environmental Protection
Agency (EPA) has determined that nearly $40 billion is spent to air
condition buildings in US, which amounts to one-sixth of the total
electricity generated annually. In order to cut down these costs, EPA
has come up with different roof materials and plans.
products should meet two specific conditions namely (1) They must be
reflective, referring to the amount of light energy being reflected away
instead of absorbing and (2) They must have high emissivity, referring
to the quickness of how the absorbed energy is emitted into the
By research, it has been found that light colors
are effective in reduction of peak demand for cool energy in buildings.
Normally, the roof system is the heavily exposed part of a building to
sun and it tends to absorb energy, serving as a large heat sink. Hence
based on the color of the roof and its reflective nature, the
temperature rise within the roofing system can be altered. When the roof
is enveloped by a white reflective material similar to a single ply
membrane, plenum air space temperature lowers to 90ºF unlike 120ºF in
the case of dark-colored roofs.
