Simple solutions that cost nothing to improve energy eficience in your home, and make saving in your home budget also
There are some really cheap improvements in your home that can bust your energy efficiency, and on that way save energy consuming and money for bills.
Solar Orientation
The most energy efficient green strategy is designing and siting your new home to take advantage of solar gain. This design technique is called solar orientation and can reduce heating and cooling costs. If you can tell your left from your right, you can solar-orient your new home as well as the pros.
In northern latitudes solar heat gain is highest on façades that face south. To optimize the way your home uses this free energy align the building on an east-west axis so the largest façade faces south. This allows the sun’s energy to warm your home during winter months and can cut heating costs up to 20%.
When your home is solar-oriented to capture the sun’s warmth in winter you’ll know where to shade in summer. During the cooling season, the southern exposure of your home still gets the most sun but with the sun at a higher aspect so it’s easier to shade.
Use awnings, pergolas or deciduous trees strategically at south-facing windows. All of these simple design considerations offer enough shade to cut your cooling costs up to 40%
Natural Ventilation
Natural ventilation uses the existing wind patterns that surround your home to cool the interior and provide a more comfortable thermal environment. Placing operable windows to take advantage of thermal convection allows for natural ventilation.
Thermal convection is a simple principle of physics: warm air rises. Even on slight inclines, cross-ventilation can carry warm air out of your home. Another design technique encourages stack-ventilation - providing a path for warm air to enter at a lower elevation and travel upwards through your home.
Stack-ventilation can be facilitated mechanically with whole house and ceiling fans. Both of these elements can draw warm air up and out in hot seasons. With the flip of a switch, fans also help keep warm air circulating comfortably within living spaces in colder months.
Whole-house and ceiling fans reduce the need for air conditioning and help take advantage of natural ventilation. The result is a healthier indoor environment and considerable savings on electricity as fans use a fraction of the energy that AC uses.
Go Low Flow
High-efficiency toilets (HET) and showers provide comfort without wasting water, one of the most precious and finite natural resources. These water conserving fixtures can also save you thousands of dollars off your water bill over their lifetime.
In the past, toilets were notorious water wasters using up to 7 gallons per flush. Today’s high-efficiency toilets use less than 1.6 gallons per flush and perform better than outdated models. Many states offer rebates for high-efficiency toilet purchases and homeowners who choose HETs over conventional models can expect annual water bill savings of about 20%.
High-efficiency showerheads offer more water and money savings. Compared to 5.5 gallons per minute (gpm) in the past, today’s low gpm showerheads use 2-2.5 gpm without compromising comfort. This small element in your new home can save you up to $100 per year on your water bill.
