10 Steps to Maximize Your Energy Audit

energy-audit10. Don’t Get the Free Audit – Energy Audits are like all other things in this world. You get what you pay for. If you’re willing to take a day or a half day off work to have an energy audit on your home. Then it’s presumed that you intend to generate enough data to either satisfy an outcome, or solve a pesky problem that you may be having. Auditors who perform free audits do not get paid very well, think sub 40K per year. As so, they may not be as professional or as motivated to serve you as an auditor for hire.

9. Gather Your Records – An Energy Audit without clear usage histories on both your home’s heating fuel usage and the electricity associated with cooling, operating appliances, and lighting. Is likely to become an audit filled with anecdotes, probables and maybes. For instance, the auditor may very well miss the three space heaters you run in the deep of winter that costs $700 per year, or that your base-load domestic hot water usage cost is way too high. Most utility companies have at least a one year history of usage on each bill. So even just your most recent bill will really help out.

8. Be Prepared to Answer Questions – A good audit should always begin with the auditor taking the time to ask questions. He should be concerned with the history of the house, behaviors of the occupants inside the home, as well as finding out about any specific concerns that may have prompted the audit. And of course what sort of desired outcome there is for the findings of the audit.

7. Prepare the House – Do you want a really good audit? Or do you want someone to clean out your fireplace and move boxes around in the attic and basement. Auditors will burn lots of calories during the 2-4 hours they spend with you. Blower door testing, infrared imaging, combustion analysis, manual inspections of dark, tight places. If your fireplace is dirty with wood ash, clean it out for a safe blower door test. if you have furniture in front of crawlspace access doors, move it out of the way. I assure you, after doing over 2,000 private audits. If you take these steps prior to the audit, and maybe mention it in passing to the auditor at the beginning. He will work harder to maximize your audit.

6. Be At Home – Auditors are not magic. They will have questions for you. Because of the programs in place right now to train new auditors. It’s pretty likely you may have an auditor who hasn’t been in the field that long. He will need some guidance. Someone who can help him sort out what he thinking. I’m not saying you should stay in his “hip pocket” the whole time. But do make yourself available.

5. Don’t Sweat Infrared Imaging – I had a call from a guy last summer who said he wanted an audit but wanted to wait for winter so we could infrared image his walls. If auditors could only work in ideal infrared environments, then it would not be a viable occupation. Infrared is useful for about 4 months out of the year. Unless it’s less than 40 degrees outside or greater than 85 degrees, it just isn’t that accurate on the building envelope. Anything that can be determined on an ideal day for thermal imaging, can be determined on any day regardless of temperature, provided the auditor is knowledgeable and patient enough to carefully come to his conclusions.

4. Do They Do the Work Also, or Just The Audit? – Sure it sounds good: Have an independent professional who is not tied to the outcome in any way help you to prioritize energy improvements. However, here is how it happens in the real world. The real cost of a full service energy audit is about $500. Auditors who charge $500 don’t stay very busy. Auditors can only afford to do it for less if they also make money on energy upgrades. My preference is for the firm who does the audit and makes money on the absolute most cost effective measures. Which is usually some weatherization. This auditor should be an absolute expert on building envelopes and also offer real good advice about windows, doors, hvac, and lighting. But would leave the big ticket work up to those who specialize in it. This type of auditor can usually perform an audit for a couple hundred bucks or so, and more often than not will also earn a contract worth 1-4K. Don’t worry. Those first weatherization dollars pay for themselves quickly.

3. Do the Upgrades – No, you don’t have to do them all at once. Yes, you can start with the most cost effective first and then work your way through the list. But do them. IT WILL improve the value of your home.

2. Be Nice to the Auditor – Is he thirsty? Would he like a snack? Smile and thank him for coming out. Trust me… he’s much more likely to find the draft at the far end of that tight, dark crawlspace if he likes you.

1. Tip Him and Offer Referrals – Hey, he worked hard. Carried equipment in and out. Didn’t complain about your dog jumping all over him. Cleaned up after himself. Came up with some good ideas. Maybe saved you a pile of money because the windows or furnace you’re worried about aren’t ready for replacement just yet. That’s right… show him a little extra green so his lunch is paid for today.

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.

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.
