Steel buildings
are a green choice. They’re energy efficient in many ways. The
materials for steel buildings are nearly always 100 percent recycled and
recyclable, reducing the strain on the Earth’s natural resources.
Pre-fabricated and pre-engineered steel buildings are also produced more
efficiently than wood and masonry buildings, and because they’re all
delivered in one shipment, they also put less of a strain on the Earth
in the delivery process. All in all, steel buildings are already the
ecologically sound choice when you’re putting up a new building.
However,
there are a number of things you can do to make steel buildings even
more energy efficient and Earth-friendly than they already are.
Insulate Your Metal Building
Uninsulated
steel may be weather tight, but it has a high rate of heat transfer or
conductivity. Whether you live in a climate that gets exceptionally hot
or exceptionally cold, you’ll want to invest in good insulation for your
steel building. Many steel buildings are designed to make installation
of insulation as easy as putting panels into place before closing up the
interior walls. Keep in mind that metal buildings
without insulation are more prone to trapping moisture and vapor, so
insulating your steel building serves more than one purpose. With proper
insulation, steel buildings are far more energy efficient, saving you
money by reducing the energy used for heating and cooling.
Use Renewable Energy
Steel buildings offer the ideal platform for renewable energy systems. Solar
panels can be easily mounted on the roof. If you prefer, you can use
solar thermal energy to heat water and heat the building at the same
time. By choosing renewable systems for your energy use, you can reduce
your utility costs by as much as 50 percent.
Choose an Energy Efficient Roof
The
roof you choose for your steel building can make a very big difference
in the amount of energy needed to keep your building’s temperature
comfortable. Most metal building suppliers offer a number of different
qualities of energy efficient roofs from which you can choose. If you
live in an area where the temperatures are generally high and your major
utility expense is for cooling, choose a light-colored reflective roof
to minimize your energy costs. If you live in a region where the winters
are cold and there’s significant snowfall, choose a dark roof which
will absorb and retain heat and contribute to snow melt.
In
addition to these fairly standard ways of increasing the energy
efficiency of steel buildings, keep your eyes peeled for new
developments. Over the next few years, for example, technological
advances in solar power may bring solar paint to the market, making it
possible to paint steel buildings with color that will also supply
renewable solar energy to power your appliances and lights.
