Energy Efficient Home Building

Since the dawn of time, man has attempted to
harness nature. It's something of an obsession.
We've cultivated crops, domesticated animals,
built cities, dug up fossil fuels, and even
landed on the moon. But, the most common and
powerful source of energy at our fingertips has
been ignored by many executives and innovators
for far too long. Until very recently, solar
power has been a passing "fad" that only the most
die-hard of green energy converts and NASA would
tout and yet the technology never died. It
continued to develop, to innovate, and to become
more efficient. The first solar cell was created
in 1941 by an enterprising American working with
silicon named Russell Ohl. It's been 70 years
since that first breakthrough and solar
technology has come a long way. Cars have been
built with solar cells. Houses have been taken
off the energy grid with solar and wind energy
sources. You can go out right now and buy your
very own solar energy kit and start tapping into
that great big orb in the sky yourself.

Technology is a wonderful thing. It provides
endless opportunities and with the world
realizing with increasing urgency that our
traditional energy sources just aren't cutting it
any longer, solar is finally coming into its own.
This is a soon-to-be multi-billion dollar
worldwide industry. And, with the right tools and
knowledge in your back pocket, you can be at the
forefront, heating your water, powering your
garden lights, or even bumping your entire home
off the energy grid once and for all with green
energy. And it all starts with knowledge - the
basic facts about how this innovative technology
actually works and why you haven't heard nearly
enough about it in the last decade as our oil
prices have skyrocketed. If you've never heard
anything else about solar energy, you've probably
heard about or seen those foil lined, shiny
surfaced solar cells that sit atop businesses and
schools. They're called photovoltaic cells and
they are just one form of technology at our
finger tips used to convert the sun's rays into a
viable, usable form of energy for our homes,
electronics, and cars.

But, with the right technology, the sun can be
used for all sorts of other energy transference.
The dream of converting your entire home to solar
dependency doesn't have to be hard. You can
ignore the critics that say it's a passing fad or
that the savings take too long to manifest. The
"green" in home construction should not be an
afterthought it should be part of all planning.
Building an energy efficient house starts with
careful evaluation of the building site and the
climate in order to determine optimum orientation
and design. There are now energy-related software
programs which can assist in this effort. Points
to take into account include how the sun's
latitude and access will affect the home's
heating and cooling requirements placement of
windows to maximize solar gain in the winter
months and reduce it in the summer and whether
there are planned outdoor areas which will be
affected by shading or access to the sun. It is
also necessary to consider the direction of
prevailing winds - whether the home will be
subject to cold winter winds or receive cool
summer breezes from what direction do snowfalls
and drifting come and whether the location of
the home will increase or decrease required snow
removal.

It's also necessary to evaluate the natural
drainage pattern of the site in order to design
the home in such a way as to maximize natural
drainage. This minimizes possible future water
damage, and retains as much of the original
topography of the site as possible. A
well-designed and well-constructed green energy
efficient home reduces the amount of natural
resources which will be needed for future
operating costs, as well Simple Off-Grid System
Review as the amount of construction material
needed. Some things to take into account include
locating rooms and spaces with low HVAC
requirements (such as garage, storage rooms,
breezeways) towards the colder areas of the site
limiting the size and number of windows on the
north side of the home and in the service rooms
of the home locating operable windows to provide
cross ventilation (free cooling) in the warmer
months. Siting and building design should take
into consideration how daylighting will affect
every room in the home, since a proper
daylighting strategy can significantly reduce the
amount of electrical lighting required.
