What is the Definition of a Green Home?

green-homeThe term green home is being used more and more often in the residential building industry, but what does it really mean. According to the Green Building Council of Australia a green house is “a high performing home that is energy and water efficient, has good indoor air quality, uses environmentally sustainable materials and also uses the building site in a sustainable manner”. A green home also requires a holistic approach, beginning at the design stage and continuing on through the construction process and the eventual day-to-day running of the home. The main goal of these characteristics is to reduce the environmental impact a home will have over the course of its lifetime.

As mentioned above, a green house should begin at the design stage. Incorporating green design elements at the initial stages of a home construction will ensure the home can take advantage of the surrounding natural environment. By utilising the topography of the site, sunlight and breezes a green home can significantly reduce its dependence on additional heating and cooling sources. This saves the occupants money on their energy bills and reduces the production of greenhouse gases.

Choosing recycled and environmentally friendly building products is another important element of a green home. The type of materials used can affect the homes’ environmental impact and the health of the homes’ eventual residents. A green home utilises recycled timber or sustainable harvested plantation lumber for its structural and cosmetic components. It is also possible to use a range of other natural products in the construction of a green home, such as straw, mud, hemp and dirt. Although some of these materials are not conventional building products, it does not mean a green home has to look very different from a regular home. Many of the materials and finishes in a regular home contain formaldehyde and volatile organic chemicals (VOCs). Once installed in a home they continue to release gases which can be harmful to the people living in them. A green home uses materials and finishes with low or no VOCs that ensure good indoor air quality.

A green home also minimises the use of energy and water by using efficient materials and products. Water saving devices in the bathroom, toilet and laundry significantly reduces water consumption. Collection of rainwater and the recycling of grey water can further improve water efficiencies. Insulation in walls and ceilings helps maintain a constant indoor temperature reducing the need for mechanical heating and cooling. Energy and water efficient appliances can also be found in this home. They reduce environmental impacts and keep running costs down for the occupants.

Consideration of these factors and the inclusion of sustainable building techniques and materials make a green home use energy and water efficiently, provide a healthy environment for the occupants and reduce the environmental impacts over the lifetime of the dwelling.

Building to a Higher Standard

There has been an explosion of interest in going green. Everything from cars to light bulbs are being pushed to new levels of efficiency. New industries are cropping up, it seems, on a daily basis.

But what about buildings; office buildings and schools in particular. These are the places that we spend most of our waking hours, and where we consume most of the energy.

There is a movement, led by the US Green Building Council, to establish standards to which buildings are designed and constructed by. Affecting more than just the energy consumption, but also the environment of the occupants inside. Buildings are certified, showing that it has met the requirements for a particular level of efficiency.

Not only do buildings get certified, but individuals also become accredited. There are thousands of LEED (Leadership in Energy and Environmental Design) Accredited Professionals in the United States, all of whom had to pass a fairly difficult test covering the details of the “LEED” program. These “APs” act as a guide to design a building for the specific purpose of attaining high levels of efficiency.

Just as hybrid cars are more expensive than their normal, gas powered counterparts, buildings achieving, or attempting to achieve any level of certification will have an increased cost. The cost, if calculated properly, should be offset by the reduction in energy usage, and the increase in productivity of the occupants of the building. And the payback of the additional cost could come in 5 years.

A recent study released from the venture capital firm Good Energies, Inc states that around 50% of non-residential building will be green by 2015. That is five years from now. It must also be noted that these numbers also include buildings that did not obtain LEED certification, but did adhere to the guidelines. This should be recognized as tremendous growth.

Based on the ever increasing number of buildings being submitted for certification and the growing population of accredited professionals, it looks as though green building has only barely gotten started.

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.

Tips For Home Investment – List of Green Features For Remarkable Homes

The massive impact of an ailing environment is already manifesting in many pressing issues and dilemmas the world is facing today. Global warming, climate change, air pollution, flood and the like are just few of the problems rooted from the destruction of the ecology. For home buyers and owners, there are viable alternatives for you to contribute in the protection of the environment through opting for green features incorporated in the design, renovation and construction of your home.

There are Eco-friendly or green means and approach you can use in order to assure that your activity and investment is making the most minimal impact on your surroundings. So what exactly are some green features to look for and utilize in a home?

One of the topmost alternatives for green houses is energy efficiency which is basically manifested in choosing efficient household appliances, high efficiency water heating system, air sealing and extra insulation and advanced framing technique.

Advanced framing and extra insulation is known to reduce the construction costs hence increase energy savings through minimizing lumber demands and production. Through proper water heating system, you also cut off the pipeline energy loss. Choosing household appliances and equipment especially with the labels that meet energy efficiency criteria helps you reduce the initial costs of your appliances as well as your electricity bills.

Ensuring the indoor air quality of your home is another viable feature of an Eco-friendly home. You can do this through the right choice on your carpet, ventilation and paints. It is important to choose carpets with less allergen-attracting components and low-pile features in order to improve the quality of air in your home interior. Use low-toxic and low-VOC paints and make sure that your home is well-ventilated to avoid potential air quality hazards. You can use quiet and automatic electric fans or through heat recovery ventilators.

Lastly, it is of utmost value and importance that you deliberately use materials and equipment for your home project that is amenable in conserving natural resources. For instance you may opt for plastic lumber, engineered wood, brick and fiber cement siding. Plastic lumber materials are actually preferred as reliable construction materials for houses and buildings. This is a good alternative in building benches, decking, docks and fences among others. For engineered wood, a good example is laminated veneer lumber that composes of raw materials with superior performance quality which are equally viable options to traditional items used.

Most importantly, consider recycled building materials which are still of high quality without the hefty price tags. It is also making sure that the demand for construction materials is reduced which eventually means that you are also lessening the demand for the production of needed items from the environment particularly trees.

Green alternatives and features are naturally integrated in modern day houses and establishment due to its incomparable benefits to both home owners and the ecology. Educate yourself of the different green choices you have which are advantageous in your investment as well as sound and wise choices to nature.

Bamboo is Not Always “Eco-Friendly” to Use in Green Projects – Is Using Bamboo a Boo-Boo?

For several decades now, we as San Francisco home owners, contractors, architects, designers and realtors have been told that bamboo is a wonderful material for remodeling projects in that it is very low in cost (relative to hard woods) and ecologically sustainable.

How many of us have attended trade shows in the San Francisco Bay area where bamboo stole the show? These trade shows tout the wonders of using bamboo for everything from flooring to ceilings, waste baskets to coffee table furniture, and even drinking cups more. The cost of many projects could be cut in one third or even one half as bamboo is far less costly (or so we have been told) than comparable hardwoods that were not as versatile nor as eco-friendly. Before the year 2000, much of these facts were true, and no one had any reason to doubt this after several decades of using bamboo for mass industrial uses in buildings.

But around the year 2000, many growers in Asia began harvesting the bamboo stalks at earlier ages than the minimum of five years growth. These younger stalks do not yet have enough strength and durability and are best used in craft projects like basket weaving or clothing. Many homeowners. contractors and designers continued recommending and using bamboo in the early 21st century totally unaware of the results to follow.

Today, in 2010, there still are large quantities of bamboo imported into the United States each year. How many of us can tell bamboo (or bamboo derived materials) that are more than five years in age? How many of us can tell bamboo that is younger than five years of age? Probably no one can. Therein lies the problem all of us face in choosing bamboo for our next “eco friendly” project! No one can tell. Well, actually we can tell after several years of wear and tear – but who would want to waste thousands of dollars (or risk thousands of dollars waiting) if the bamboo begins to decompose several years after installation?

Perhaps in several years there will be a bamboo rating system so that those of us who choose to use bamboo for its potential strength and beauty, not to mention its functionality. May I suggest that the rating system be simple to include only three categories: A “harvested at 5 years or older from a verifiable source/ documented”; B “harvested under 5 years and therefore not of durable strength for most projects”; and C “source or harvest age unkown”. In this way the buyer can have some sort of confidence up front at the start of a project that they are truly using an eco friendly material or not.

Until that time, I will continue to admire bamboo, but I will not encourage my own clients to use it in any projects expecting long term durability, nor as a substitute for hardwood flooring. Maybe it is best used only as an attractive live landscaping plant until further notice!

If you would like further information about bamboo and ways to begin a simple easy to classify system that can easily be internationally accepted, write me. My contact information is below. The first step is for a large bamboo harvesting plantation in China to start a documentation process. Documented bamboo, fetching far more in revenues (as if it were “organic produce”) will be the impetus for change. Even if change comes slowly, many home owners, builders, and designers will happily step to the front of the line for a truly certified quality building material. Bamboo deserves a place in every home. But first, let’s at least know the age of the material when harvested.
