Modular Homes Are Really Green
There are several misconceptions about the design and green qualities of the modular home. In this installment of Best House Floor Plans, we’re evaluating five common fallacies associated with the home built off-site:
Fallacy #1: Modular homes require almost a year to build.On the contrary and depending on the size of the modular home, the factory built domicile has an assembly time of three to five days. Once the modular home is transported to the construction site, it requires only two to three months of construction time, compared to the conventional home, which requires nine months to a year for completion.
Fallacy#2: Modular homes are more expensive to build.According to national averages reported by architects, modular homes are 10 to 20 percent more cost effective than the standard built home.
Fallacy #3: Since, modular homes have to be transported from point “A” to its final site location, the factory built home is not green.Actually, many factory built homes are developed in accordance to a rating system, mandated by the U.S. Green Building Council. An example is the Leadership in Energy and Environmental Design (LEED). These pre-constructed homes are by far more energy efficient to live in.
Fallacy#4: The home built by module has only one insipid home style.Contrary to popular belief, modular homes are architected into a myriad of style options:
Colonial
Contemporary
Contemporary
Dutch colonial
Georgian
Mediterranean
Victorian
Fallacy #5: The building green concept is a marketing ploy used to promote the modular home building industry.Several years before going green or being eco-friendly was popularized, modular manufactures analyzed the amount of waste and its effect on the environment. The findings showed that significantly more building materials end up in landfills during standard home builds than the pre-fabricated home.
Moreover, the home floor plan, erected by module is green because it offers three redeeming qualities:
- It is environmentally conducive for the occupant, as well as the planet
- Decreases homeowner’s operational costs on energy
- Has a substantially smaller carbon footprint
In summation, modular homes are not only eco-friendly, but exude highly stylized characteristics, often indistinguishable to the traditional constructed home.

Energy-Efficient Mortgages
Technology Snapshot & Benefits:
Energy-efficient mortgages are one of the most beneficial and under-utilized programs the consumer can find and capitalize upon in today's real estate market. An energy-efficient mortgage can add an additional 15% of a home's appraised value to the principal of a new loan or a refinance, often at no additional cost, no compromise in the loan-to-value ratio for the borrower, and sometimes at a better rate. Yes, one pays a bit more in principal and interest, at today's rates, roughly $30-50 dollars per month, over the course of the loan. However, when this extra principal is used to install energy efficiency measures, it is not uncommon for the property owner to realize $75-100 per month in energy cost savings. When working with a lender who offers and understands the energy-efficient mortgage programs available, the steps for the borrower are very straightforward.
Estimated Cost Savings:
There are no additional costs associated with many energy efficient mortgage options, other than the cost of the additional $15,000 in amortized principal and interest (PI). By definition, the savings created by the energy efficiency measures are greater than the additional PI. This provides the assurance lenders need to conclude loans of this nature are good business.
In fact, the attractiveness of the energy efficient mortgage options also extends to lenders. What happens is that as the borrowers make the stated energy efficiency improvements and create monthly utility bill and other savings, their monthly cash-flow improves. This improvement in monthly cash-flow makes the borrower an even more stable and reliable customer, less likely to present the prospect of default.
Issues:
Most energy-efficient financing programs require that the borrower has an energy rating on their existing or new home. A rating typically involves an inspection by a professional energy rater who is certified under a nationally or state accredited home energy rating system (HERS). The Residential Energy Services Network (RESNET) provides a database of Certified Home Energy Raters by state.
Regional Issues:
Energy-efficient mortgages and other financing options for energy efficiency improvements are available throughout the U.S. and internationally.
Installation (Getting it Done):
The first easy step is to talk to a few lenders, such as the affiliates here on the site, and then prepare to have a certified energy rater come and conduct the analysis of your property. Your lender will also have suggestions as to energy raters who work with them on energy efficient mortgages, just as your lender has an appraiser with whom he/she works to conduct appraisals.

Geothermal Heating Systems
Technology Snapshot & Benefits:
Geothermal heating systems, also known as geo-exchange, ground source pumps, or earth-coupled pumps, take advantage of the earth's nearly constant temperature (45-75 degrees Fahrenheit, depending on latitude) to heat and cool buildings. They work by pumping water and antifreeze or a refrigerant under the ground to be heated or cooled by the earth and then pumped back through piping in the house. In the winter, the earth is used as a heat source, and in the summer as a heat sink. These systems are effective in any climate. The systems pollute less than traditional fuel-burning systems and are about three times more efficient. They are also more efficient than air-to-air exchange heating/cooling systems because water can transfer a greater amount of heat than air. They also have a longer lifetime than either system because almost all system components are indoors or underground. The average lifetime is 25 years for outdoor components and 50 years for parts that are installed indoors or underground.
Geothermal systems reduce the probability of a fire or carbon monoxide leak in a home because they do not require any combustion. Another huge benefit is the reduction of pollution. According to the Geothermal Heat Pump Consortium, geothermal systems reduce CO2 emissions by about 1.1 million metric tons over 20 years, which is "the equivalent of converting about 58,700 cars to zero-emission vehicles, or planting more than 120,000 acres of trees." Geothermal systems have the EPA ENERGY STAR® label, which not only indicates that using these systems benefits the health of our planet, but also that there may be incentives associated with installing the system, such as tax benefits or lower mortgages. Geothermal systems are also better at controlling relative humidity in buildings compared with other systems.
There are two different types of geothermal heating and cooling systems: open-loop and closed-loop. Open-loops systems require a body of water, and work by pumping water from this source through the house and then back into the body of water. In closed-loop systems, closed-loop piping through which water flows is buried under the ground. The piping for closed-loop systems may be installed vertically or horizontally, with vertical piping requiring a deep but thin trench and horizontal piping requiring a wide but shallow trench.
Geothermal systems are very popular among people who have used them. In fact, the California Energy Commission's Consumer Energy Center reports that 95 percent of people who have installed these systems would recommend them to others.
Estimated Cost Savings:
Geothermal heating systems can save between 30 and 70 percent on heating and cooling costs compared to traditional fuel-burning systems, and are estimated to use an average of 25 to 50 percent less electricity. These systems are often able to generate excess heat in the summer or even the winter, and a device called a desuperheater can use this excess heat from the system's compressor to heat water at no additional cost. These systems are expensive to install, costing about $2,500 per metric ton of unit, which works out to about $7,500 for the average-sized American home. This is nearly double the price of installing a traditional air conditioning unit. Closed-loop systems require an additional cost for drilling the trench in which the piping is laid, which can cost $10,000 to $30,000, although the costs of installation have decreased in recent years and are expected to continue falling. Overall, the long-term monetary benefits of transitioning to a geothermal system outweigh the initial cost. The U.S. Department of Energy estimates that the installation costs will pay for themselves in five to ten years, and then building owners will actually profit from the system for the remainder of the system's life. Schools and businesses, which will probably be using the system for a long time, could take special advantage of this profit to purchase new school or business necessities.
Besides saving money on monthly energy bills, geothermal heating systems are usually more durable and require fewer maintenance and repair costs compared with other units. Having a geothermal system adds value to a property proportional to how much monthly energy bills are reduced. Some states also offer monetary incentives for installing these systems.
Property owners who want some of the benefits of a geothermal system but simply cannot afford installation can consider an air-geothermal hybrid system, called a dual-source system. These systems are less efficient than a pure geothermal heating and cooling system, but more efficient than a pure air-based or fuel-based system. Also, dual-source systems are cheaper to install than pure geothermal ones.
Issues:
It is very important to get a qualified contractor to look at the building and land around the building to determine the best kind of geothermal system to maximize comfort, efficiency, and savings. All systems should be customized to a particular situation. It is very important to make sure the contractor is knowledgeable and qualified.
Open-loop systems are initially cheaper to install because they do not usually require drilling; however, it is important to note that these systems work only where there is a sufficient amount of fresh, relatively clean water available. If this is the case and an open-loop system may be used, you must research local regulations on discharging water and make sure these regulations are met.
Regional Issues:
Geothermal heating systems work in all climates, even extreme ones. Good contractors should be able to give advice on specific regional issues that affect drilling and installation, for example, very hard ground.
Installation:
Installation and installation costs of geothermal systems vary, depending on the type of system installed and the availability of a water source. All installations, however, involve installing some type of piping and units for converting and distributing heat. The ductwork used in these systems is the same as that used for traditional systems, so no change is required during installation. The most important thing about installation is finding a good contractor.

Reflective Roof Coating
Technology Snapshot & Benefits:
According to ENERGY STAR®, Americans spend about $40 billion annually to air condition buildings - one-sixth of all electricity generated in this country. In areas that are sunny and warm for most of the year, or have a very hot summer, the costs to individuals are particularly devastating. Reflective roof coating is protective coating that can be applied to roofs to keep a home cool without having to use as much air conditioning. Reflective roof coating is also called albedo coating, since the materials used have high albedo, or ability to reflect the sunlight. Reflective roof coatings have other benefits as well: they can increase efficiency in some air conditioning and ventilation units on the roof and because UV radiation expedites roof ageing, they also slow roof decay. These special coatings work by reflecting the sun's light and releasing absorbed heat.
Reflective roof coating is most effective for flat roofs because flat roofs usually absorb more energy than slanted roofs. The effectiveness also varies with the thickness and color of the coating, with lighter colors and thicker coatings being significantly more effective. In fact, bright white reflective coatings can have a solar reflectance of 85 percent and cut a roof's cooling load up to 70 percent.
Reflective roof coatings can be made from various materials. Paint-on coatings include acrylic paints, polyurethane, and elastomeric. These types of coatings do not require professional installation. Single-ply reflective sheets made from plastic, PVC, or rubber are effective, as are reflective roof tiles made from concrete, clay, or metal. In terms of total cost (raw price, installation fees, and maintenance fees), white titanium dioxide paint and aluminum sheets are the best choice. However, elastomeric and acrylic coatings reflect a higher fraction of solar energy. Longevity of the material used should also be considered.
No matter which materials are used, most homeowners who employ reflective roof coating experience cooler indoor temperatures and lower cooling costs.
Estimated Cost Savings:
Reflective roof coating can cut cooling costs from 10 to 70 percent depending on the coating used, climate, and the degree of sunlight to which the roof is exposed. Hot areas that are sunny for a majority of the year benefit the most from reflective roof coatings. The decrease in monthly energy bills far outweighs the costs of installation. Coatings that are painted on typically cost $15 to $25 per gallon and can be applied by the homeowner. Professional installation of single-ply roof sheets or tiles typically costs the same as installing any other type of shingle or tile; so, if installed at the initial building of a home or rebuilding of a roof, there will be little to no extra cost for the homeowner. Cost for single-ply PVC membranes averages $3 per square foot.
Issues:
Reflective roof coatings are a simple way to cut costs and help the environment. Virtually all roofs can be made to absorb less heat and reflect more sunlight using some type of reflective roof product. However, if the roof membrane is decaying, the coating will not be as effective and it is recommended that the membrane be replaced before the coating is applied. It is best to consult a professional or product manufacturer about the ideal type of coating for a specific roof.
Regional Issues:
Reflective roof coatings are not recommended for areas that are cool or cold for much of the year and/or experience high cloud coverage. They most benefit people in areas that are warm and sunny for most of the year. In warm and/or sunny cities, this coating can help fight the "urban heat island" effect, or increased temperatures due to greater reflectance and absorbance of sunlight by a conglomeration of dark, metal buildings. Decreased indoor temperatures in areas that can become extremely hot can increase comfort and reduce the likelihood of heat-related illness or death.
Installation:
Paint-on coatings are applied using a roller, a brush, or airless spray equipment, and require minimal skill to apply. The roof should be properly cleaned before applying the coating. It is important to consult with the coating manufacturer for tips and advice on how to apply a specific coating to a specific roof. Single-ply reflective shingles and roof tiles must be installed by a professional roofer.

Virtually all roofs can be made to absorb less heat and reflect more sunlight using some type of reflective roof product. However, if the roof membrane is decaying, the coating will not be as effective and it is recommended that the membrane be replaced before the coating is applied. It is best to consult a professional or product manufacturer about the ideal type of coating for a specific roof.
Regional Issues:
Reflective roof coatings are not recommended for areas that are cool or cold for much of the year and/or experience high cloud coverage. They most benefit people in areas that are warm and sunny for most of the year. In warm and/or sunny cities, this coating can help fight the "urban heat island" effect, or increased temperatures due to greater reflectance and absorbance of sunlight by a conglomeration of dark, metal buildings. Decreased indoor temperatures in areas that can become extremely hot can increase comfort and reduce the likelihood of heat-related illness or death.
Installation:
Paint-on coatings are applied using a roller, a brush, or airless spray equipment, and require minimal skill to apply. The roof should be properly cleaned before applying the coating. It is important to consult with the coating manufacturer for tips and advice on how to apply a specific coating to a specific roof. Single-ply reflective shingles and roof tiles must be installed by a professional roofer.

What you eat and the Environment
Mean, Lean Vegans (from ThreeHugger.com)
This isn’t the first time here on TreeHugger where we’ve shown support for plant-based diets. We’re usually hyping up its lower carbon footprint and its myriad of nutritional benefits, including low levels of saturated fat and cholesterol and higher levels of cancer-fighting fiber, folate, antioxidants and phytochemicals.
Lesser mentioned though is the link between the growth hormones found in conventionally raised meat, poultry, and dairy products—and weight gain. According to Sustainable Table, though the USDA and FDA claim that there is no connection, there is growing concern that the hormone residues can disrupt human hormone balance leading to weight gain, among other scary health risks.
Very Svelte Vegetarians
Though PETA tells us that, "Vegetarians are, on average, up to 20 pounds lighter than meat-eaters," not all veggies are created equal. If you’re a vegetarian who considers polishing off a box of Teddy Grahams dipped in non-organic peanut butter part of a nutritionally complete and slimming meal—think again.
We’re talking about eco-conscious vegetarians eating primarily plant-based and organic diets in moderation. Here’s why. While peanut butter might seem a smart meat-free source of protein, if it’s not organic you may be doing more harm than you think. Pesticides and fertilizers are fat soluble. So when you down that chunky, nutty goodness—you could be getting a good dose of toxins, too. Research is showing that when the body—especially organs like the liver—get overwhelmed with toxic matter, it becomes more difficult to shed pounds.

Reinventing Reality
You may or may not be in the Real Estate industry....this goes to everybody...I think is fair to say that this economical time changed and touched every one's lives...I'm so sick of hearing people complaining about it....we are all better off than many people around the globe! People often say " I use to, could have, should have, would've...." sounds like the voice of procrastination to me, what a waste!
Let's start thinking of the glass being half full and stop using the excuses we're so use to...instead of being terrorized about the bad economy lets be thankful we live in such a plentiful Country that has been like that for several years and given many opportunities that we couldn't have had anywhere else...Instead of being scared that unemployment rates are around 10% let's be thankful that 90% of us are employed (active age), lets open businesses to provide jobs for the 10%....As uncomfortable as we may be, this is time to move and make things happen...I am uninterested in hearing any body's complaints anymore, please beware!
Besides, this crises is a great opportunity for us the Green Up our Country, our mentality and perhaps our relationships....because in times like this....suddently...becomes really clear who are our true co-workers, friends and even family....isn't that the true?
