Geothermal heat pumps are one of the most energy efficient ways to heat and cool a home and provide hot water. More and more homeowners are discovering the benefits of these systems, which tap the relatively constant temperature of the Earth a few feet underground, for both new homes and retrofits in existing houses.
According to the Environmental Protection Agency (EPA), geo exchange systems are the most energy efficient, environmentally clean, and cost effective space conditioning systems available (source: “Space Conditioning: The Next Frontier”, EPA 430-R-93-004, April 1993).
Simply put, a geothermal system moves the heat from the earth (or a groundwater source) into the home in the winter and pulls the heat from the house and discharges it into the ground in the summer. The underground (or underwater) piping loops serve as a heat source in the winter and a heat sink in the summer.
Unlike air temperatures, which can vary greatly, a few feet below the earth’s surface the ground remains a relatively constant temperature. This ground temperature is warmer than the air above it during the winter and cooler than the air in the summer. Geothermal systems take advantage of this by exchanging heath with the earth though a ground heat exchanger rather than with the outside air (as with air conditioners).
Geothermal systems offer many benefits including: cost savings, durability, low maintenance, quiet operation and low environmental impact.
Because a geothermal system is so efficient, it uses a lot less energy to maintain comfortable indoor temperatures. This means that less energy – often created from burning fossil fuels – is needed operate the system. According to the EPA, geothermal heat systems can reduce energy consumption, and corresponding emissions, up to 44% compared to air source heat pumps and up to 72% compared to electric resistance heating with standard air conditioning equipment.
While the cost to install a new or retrofit geothermal system can be twice as much as a conventions gas or electric system, the immediate lower rate for heat, air conditioning and hot water makes the payback point at between 3 and 10 years. A qualified geothermal system provider and installer will be able to make all the calculations necessary for them to provide you with a complete and concise report that will provide you with the data on your break even point.
We are currently working with our qualified sub contractor for installation of a geo thermal system at one of our local builds here in Northern Michigan. Our homeowner is very green minded and has decided to make his home at least Energy Star rated. Watch throughout the next months as we report on the accomplishments that are made to reach this goal.
IT IS EASY BEING GREEN!
Green building offers homeowners the opportunity to have a safer, healthier, energy efficient and environmentally friendly residence with the same look and feel of a superior high-quality constructed luxury log home. A green built home is simply a better built home -- from the site planning, to preservation of natural features, to the structure of the house itself, including increased insulation to recycled materials, energy-efficient appliances, water conserving fixtures and more!
Keep in mind: You CAN have a luxury log or timber frame home and still go green!
What is green building?
Green building can be broadly defined as building new homes in a manner that conserves resources. Green building can include numerous elements affecting cirtually every aspect of construction. Most often it involves one or more of the following keys to energy efficient construction:
-> Land planning and design techniques that place the home for heating/cooling advantage, preserve the natural environment and minimize disturbance of the natural habitat.
-> Site development considerations that avoid erosion, minimize paved surfaces, runoff and protect vegetation -- especially trees!
-> Energy efficiency in heating/colling systems including your appliances and lighting, as well as the building envelope.
-> Reduces waste during and after construction, including reuse and recycling during construction and for the life of the home.
What you really need to know: Green building is not "ALL OR NOTHING". There are many levels of green efficiency -- from simply utilizing energy saving appliances, to achieving a certified "GREEN BUILT" status for your luxury home. Every step towards conservation and preservation of resources will help the environment. And, you don't have to sacrifice comfort to build green. Most of today's green-built homes are virtually indistinguishable from other luxury homes.
Why should you consider 'going green' with your new Town & Country Cedar Home?
Ask how we can include 'greener' technology in your new Town & Country luxury home that will improve safety, provide healthier indoor air quality, be more energy efficient and environmentally friendly!
Safer Homes: Our luxury homes are sealed tighter than ever before. This tightness helps to keep deadly gas from migrating between the house and attached garage. Closed combustion heating and water heating systems can be included to reduce the potential for carbon monoxide pollution inside the home. And, we recommend a CO monitor in all living areas.
Healthy Living: Your mechanical ventilation system can include air cleaners for improved indoor air quality. We can also help you select building materials and finishes with lower chemical content.
Energy Efficiency: Want to lower your energy use? We can help you lower your energy expense and limit the amount of air pollution created by general home living by steering you towards even stronger insulation packages, use of cutting edge window technology, as well as low water and more energy efficient appliance selections.
Helping the Environment: Remember that proper placement of your home on your property will make a big difference to local watersheds. Ask us how we can assist you with maintaining your property's natural environment!
