Learning More About ICF Construction

By now, many people of heard of and are intrigued by green building techniques. Vertical ICF construction is one green building method that has seen resurgence thanks to its energy efficiency and environmentally friendly construction and installation process. Traditionally used in commercial building construction, ICF construction is as popular as ever in providing energy-maximizing savings and structural integrity to residential consumers. ICF, or Insulated Concrete Forms, are a type of wall that is generally made from cement-bonded wood fiber (usually made from recycled wood and cement) and polystyrene.

The strength of a building constructed with ICF technology will be unmatched in terms of strength, energy efficiency, noise reduction and comfort when compared to a structure built with typical wood frame construction. Termites and other pests and insects will not be attracted to insulated concrete forms, therefore eliminated the risk of having structural integrity compromised. ICF walls are mold, mildew and allergen resistant as well, so you can rest assured that your home would be a comfortable environment for you and your family.

Vertical ICF walls are ultra efficient when it comes to energy savings. Concrete and foam is the best insulator available for your home. You can save as much as 50% to 80% on your heating and cooling bills when comparing to energy costs of a traditional wood frame house. The high insulation value also makes it an ideal sound barrier, keeping exterior noises out of your home and interior sounds from escaping, allowing for better security and privacy.

Insulated concrete forms can withstand the highest winds that you would encounter with severe weather including hurricanes and tornados. Winds of up to 200mph are no match for ICF construction, and neither is fire. Insulated concrete forms are able to resist fire for up to 3.5 hours. Furthermore, ICF walls will resist mold and will not rot due to excess moisture, so your maintenance and general upkeep will be virtually non-existent.

Installation of insulated concrete forms is relatively easy and can be done quickly with an experienced green building contractor. Many ICF walls are made with recycled and environmentally friendly materials, non-toxic and not manufactured with any harmful chemicals such as formaldehyde. Installation is easy and even the waste products are kept to a minimum. Cleanup will be quick and easy, and the leftover waste products from the construction can be recycled.

It is easy to see why Vertical ICF construction techniques are gaining popularity, especially within residential buildings. The energy efficient, reinforced concrete walls have an unmatched fire tolerance, a high resistance to termites and pests, resistance to mold and mildew, and will result in the maximum amount of energy savings possible. The structural integrity of a home or building constructed with Vertical ICF walls will be much more enhanced to those constructed with traditional wood frames.

Green Building – Sustainable, Energy Efficient, Quality Construction Under Threat

In the midst of our recent economic crisis, the US federal government’s interventionist policies have again redeployed finite resources in contravention to market forces. Consumers and many custom builders have been pushing for better quality, sustainable, energy efficient construction. Unfortunately these market forces have been overcome by government intervention. The government has incentives for first time homebuyers who typically purchase cheaper starter homes. As a result almost all new construction is being undertaken by large tract builders who specialize in cheap housing. This end of the market is very price sensitive leading these builders to continued with larger designs that sacrifice quality for size.

Contrary to the belief of the US Congress, capital cannot be created by printing money or authorizing programs intended to create jobs. In a free market capital is deployed efficiently to areas with the best returns. When the government intervenes, it may skew the use of resources to less efficient enterprises. History provides us with numerous examples, but we do not have to look far back to see one of the best.

The deep recession we are experiencing resulted in large part from government interference in the housing market. The American dream has become the American nightmare. Successive governments, both Democrat and Republican, since the Great Depression have done everything they can to encourage privately owned housing. Government bureaucracies like the Federal Housing Administration and government sponsored, now government owned, entities like Fannie Mae and Freddie Mac artificially created a market for low interest loans to high risk customers. In a perfect storm, the Federal Reserve artificially depressed interest rates for a short-term economic boost.

Without artificially low rates and low credit standards, it is unlikely that the production of homes would have risen from 1.6M in 2001 to almost 2.1M by 2005. Post deflation the housing starts fell to 554,000 in 2009. At the beginning of the expansion, the Federal Funds Rate in January 2001 stood at 6%. When housing peaked the rate had been lowered to 1%. Not only did the volume of construction increase during that time, but the size of homes increase dramatically as did the price. Consumers were encouraged by lenders to purchase the largest home they could afford to take advantage of a once in a lifetime opportunity. Capital that might otherwise have been used in other areas of the economy was deployed in housing at artificially low rates. The result was catastrophic.

The same government is again intervening through first-time homebuyer tax credits. Coupled with low interest FHA loans having 3% down payments, they are creating some of the previously existing conditions. In addition to risking another bubble, the tax credits funded by all taxpaying Americans are being funneled to large corporate builders that specialize in low-end housing. This is evidenced by the fall in the median sales price in 2009 to $209,000 from a high of $262,000 in 2007.

Some of the larger builders have developed smaller plans, but they have mostly done so to meet the lower price points that the government influenced market demanded. They are not increasing the quality, sustainability or energy efficiency of their new homes. Though not all large home construction has stopped, only the truly wealthy, who tend to build better constructed homes, are still building. Homes of this quality usually include energy efficient systems and last much longer; both qualities of sustainable construction. Much has been written about “McMansion” homes, but generally homes in this market are not included. That is discussion for another day.

While tract home builders dominate the starter home segment, custom builders control the large home market. The real battle will be for the “move up market”. This market will determine the character of American housing for the foreseeable future. Move up consumers will chose between low quality, lower-cost homes built by large corporate builders and high quality, higher-cost homes built by small custom builders. Given the same available dollar for construction, the tradeoff is size for quality.

Assuming market forces determine lending limits, the average price of homes in the move up segment will likely remain much lower than previously experienced. At the peak the move up segment ranged easily into the $1M plus range. Those who grew accustom to the quality of higher priced homes will not likely abandon their affinity for hardwood floors, commercial-grade appliances, custom cabinets and granite tops. To match those features with a lower total budget, consumers will need to build smaller, high quality homes. The skill set to build these homes lies with the custom builder.

If Americans are truly interested reducing dependence on foreign energy and increasing sustainability in the housing market, we will need to decide to build smaller homes to offset the higher cost of quality construction. While it is possible that tract builders may chose to build smaller, their main advantage currently is delivering large size for a low price. Their organizations are not set up to deal with the custom aspects that would make their housing sustainable or more energy efficient. Through builder association programs custom builders have become much more educated in energy efficient, sustainable building to go along with their inherent quality.

The question now is whether the government will continue to incent consumers to continue a behavior pattern contrary to free market forces. If all new construction continues in the low end of the market, it will drive many of the remaining custom builders from the market. Already the number of builders belonging to professional organizations like the National Association of Home Builders has been drastically reduced. Most small custom builders are surviving only through remodel work, but if the market continues much longer many will likely move to other work. Rebuilding the knowledge base and expertise may take years and impact the overall quality negatively for year to come.

Getting in on Green Real Estate

If you need to sell your home but are having difficulty interesting buyers, there is an alternative available. The green real estate market has skyrocketed in the past five years, thanks to new interest in sustainable living and the passing of eco-friendly legislature. Here are some tips for transforming your home from dull listing clutter to green real estate commodity.

Invest in Making Green Real Estate

If you are truly committed turning your home into a green paradise, and thus make it more marketable, you may have to make a large investment. Map out the types of changes you want to accomplish, such as adding solar panels and water efficiency kits. Determine how much each project would cost, whether you can do it yourself or have to hire someone to do it for you, and how long the project will take.

With all of this in mind, research the kinds of houses that have made these adjustments and how much they have sold for. Contact a selling agent to ask questions. Get a home appraisal prior to these green projects, and also ask them their opinion on how much your home would be worth after the projects were completed.

Small Ways to Make Your Home Eco-Friendly

If you simply cannot afford the investment, or you don’t think the investment will yield greater returns, there are small things you can do to make your home more marketable as green real estate.

Check your home’s energy efficiency. Replace any insulation that may be allowing heat to escape. Check doors and windows for cracks in panes, sealant fails, or even holes. These small repairs will all save big on heating and air conditioning costs.

Replace your regular light bulbs with energy efficient CFL, or compact florescent lights. Also, install new showerheads and faucets, replacing them with low-flow technology. This will save water. Installing an insulating jacket around your water heater saves money and energy.

Plant a Tree

One of the simplest and best ways to make your home green is to actually surround it with green! Planting a tree outside will produce shade in the summer, and can reduce cooling costs by up to twenty-five percent. Trees and shrubs can also block strong winds from your home, which prevent them from coming in through compromised windows or leaks in your doors. This can save on your heating costs by up to twenty percent.

In the summer time, your home will be more attractive to potential green buyers if it is surrounded by plants and flowers. You can purchase cheap flowers ready for planting from a local greenhouse. Ask the greenhouse attendant for how to plant and care for the flowers if you are not sure.

It is also easy to make your home appear greener during the winter time. Keep plants and flowers indoors. Be sure to water them as needed, and consult online manuals for how to care for particularly tricky plants. As soon as a potential buyer walks in and sees that your house is a great place to have plants, the chances are that they will be more interested.

Promoting your house as a piece of green real estate can make it much more marketable. Decide whether you can make big investments like solar panels or replacing appliances with energy efficient ones. If not, there are many small things you can do to make your home more eco-friendly and attract those green buyers.

Energy Proofing Your Windows

When we think of Energy Star compliant we tend to think of appliances such as televisions, computers, dishwashers, refrigerators, etc and the amount of energy associated with their use, but seldom do people realize that the Energy Star compliant also applies to your home, more specifically, your windows.

The EPA (Environmental Protection Agency) broadened their criteria to include energy efficiency for residential homes and commercial buildings one of the criteria for judging a home for how efficiently it uses its energy is to test its windows for any energy leaks.

The reason why particular attention is directed toward the windows is because it is estimated that around 30% of the home’s total energy is lost because of them, while at the same time being responsible for as much as 25% of your heating or air conditioning bill due to the air these inefficient windows allow to leak in and out. This means that your home is much cooler in winter than it should be and much hotter in summer, especially with the way older windows are designed, this is because homes greater than 14 years weren’t built with a green perspective in mind. Around half of all the homes in the US alone were built with single paned glass windows which is responsible for energy losses.

Fortunately with developing technology and a green, sustainable picture in mind has seen the advancement of design where windows are now twice as energy efficient than compared to 25 years ago. With reduction of lost energy come smaller utility bills. With older windows because hot and cold air is constantly being lost the more energy must be expended in order to counteract this loss, resulting in higher energy bills.

Window proofing for leaks can help you save money on your heating while making use of the existing energy within the home meaning you use less energy without sacrificing creature comforts or without having to make any real major changes to your lifestyle.

Budget is a big factor when it comes to replacing your windows with more energy efficient ones which can set you back around $15,000, a home energy audit is always highly recommended to test if completely replacing your windows is the best solution compared with less costly alternatives such as replacement inserts rather than replacing the entire window.

There are several benefits to energy proofing your windows:

Less money spent on heating and cooling due to your windows ability to better facilitate the existing energy more efficiently.
Enhanced comfort and living standards with a warm, dry living environment.

Improved health and reduced illness due to proper heating and the reduction of condensation and the dangerous fungal molds usually associated with damp living conditions.

Less carbon emissions due to the reduced need to consume more energy and the less impact on the environment associated with that energy production.

Better use of natural light.

Reduced noise pollution from the double glaze insulated design.

Receive an Energy Star tax credit through energy efficient windows. You may be eligible for a tax credit of up to 30% of the cost of your windows, up to $1,5002. What better incentive than to be rewarded for your green efforts. However, you must check for eligibility as not all windows carrying the Energy Star logo qualify for this rebate.

Here are some tips to energy proof your windows:

Double pained windows contain an insulating layer of air between the two pains which reduces the amount of heat lost and gained.
Triple glazed on the other hand has two insulating air layers separated by three layers of glass which makes this one of the most efficient designs around not only with its obvious energy savings but its reduction in noise pollution.

Those living in cooler climates are now starting to use energy efficient windows containing low emissivity coatings on the glass preventing additional heat loss.

Energy efficient windows are a lifestyle choice with big rewards as the savings in energy bills over a lifetime add up nicely to a small fortune.

Geothermal Heating Systems

Geothermal heating systems provide warmth to a home by extracting heat from a heat source. The theory behind it is that heat in essence can be extracted from any source regardless of its temperature. This means that even cooler environments can make potential heat sources, however sources that are warmer in temperature have greater efficiency.

The concept behind geothermal heating systems is that it works much like a refrigerator which uses a heat pump to force heat transfer. Geothermal heating systems have the ability to trap heat from a cold environment and transfer it to a warmer one and are able to manipulate the natural direction of flow.

Geothermal heating systems use the ground as a heat source to capitalize on the marginal temperatures immediately below the earth’s surface. Shallow earth at depths of 30 feet make it an ideal heat source for geothermal heating systems because the temperatures at these levels vary only slightly, even with seasonal fluctuation, making it a reliable and efficient form of energy generation.
Not only do geothermal heating systems heat in winter but they can also cool in summer as the process can be reversed, rather than pumping heat into a home, heat is extracted to the ground.

Geothermal heating systems are becoming a popular form of alternative energy with an excess of one million units sold worldwide and an estimated annual growth rate of 10%.

Although geothermal heating systems may cost more than conventional systems the returns are financially rewarding with the reduction of electricity bills, the cost of materials and installation can be recouped within 3 to 7 years. Consider geothermal heating systems a long term investment that will not only pay for itself but will also make less of a dent when it comes to the impact of your carbon footprint as geothermal heating systems that operate under closed loop conditions are virtually emission free.

In addition to saving more in the long run, geothermal heating systems are long lasting and durable with their estimated lifespan being around 25 years making geothermal heating systems a solid choice.

There are several different types of geothermal heating systems and they range from direct exchange systems to closed loop, vertical and horizontal closed loop systems.

Direct exchange geothermal heating systems operate by way of a closed loop system of refrigerant in direct contact with the ground. This particular system is called direct exchange because it does not require the use of an intermediate fluid to facilitate the transfer of heat. This means that only heat is transferred across the pipe for immediate use making them one of the most efficient types of geothermal heating systems out there on the market. Installation of the direct exchange geothermal heating systems is also more economical in comparison to a closed loop water system.

Closed loop water geothermal heating systems unlike their direct exchange counterparts need the assistance of a heat exchanger linking both refrigerant and water loops and their respective pumps. Closed loop water systems have lower efficiency than systems not requiring the use of water as they need larger pipes meaning increased expended energy to power them along with escalated installation costs.

Geothermal heating systems are a great way to take advantage of geothermal technology providing an efficient, clean low cost method of energy generation.
