Who Do You Blame for Your Energy Lemon?
comments (39) August 27th, 2009 in BlogsSo I was talking to Tucker Windover, a carpenter who writes for this magazine, and he said that every new house should have a sticker on the front door, just like the ones they put on appliances, that tells you how much energy this model is going to save you. "This house is air-tight and insulated to R-45. It will cost an average of $XXX for heat, hot water and electricity." Here are a couple of reasons why I happen to think this is a great idea.
A month ago, I went to see an author who was trimming out a big new spec house in a suburb filled with big spec houses. I was surprised to see that they had stuffed fiberglass around the windows (instead of spray foam), so I asked about the rest of the house, which is on the market for somewhere between two and three million. According to the carpenter I spoke to, the builder didn't insulate beyond the bare minimum of R-19/R-30, didn't use rainscreen walls, and generally seemed to build as if it were still 1975.
A few days later, I happened to browse through Breaktime and noticed a thread that asked if Fine Homebuilding had "gone Green Crazy". A couple of the posters suggested that while it had its merits, "green" building was just a fad.
So what's the issue? Certainly the examples above aren't representative of all builders. But you know they're out there, probably more than we'd like to admit. When I see guys building houses like the spec house above, I wonder how many other builders are doing the same thing - putting up sub-standard housing for people who don't know better. Do they really think it's a fad? Is oil a fad, too?
But is it only the builders' fault? They only build what people will buy, right? Why doesn't the home-buying public demand a better house? How can they tell at a glance? They can't see through the walls, and if they could, they might not understand it anyway.
So let's make it easier for everyone. A big yellow sticker on the front door of a new house would force the builders to become competitive - they couldn't get away with building crap. Eventually, builders who ignored the energy crisis would end up like the last industry that ignored it - the auto industry. Except that this time, I hope the government doesn't bail them out.

Masonry Heaters will never turn into a lemon, even if the fireplace isn't used, as it provides a central focus of the home. When they are used, though, they drastically reduce a consumer's dependence on fossil fuels and the power grid. Add in options such as baking ovens and water heating elements and you've got a Green Machine!
A Masonry Heater owner in Amboy, WA heats his entire 2,000 square foot home as well as have hot water generated by the fireplace - all from just one 3 hour fire!
Mastercraft Masonry has built these fireplaces for over 25 years - with many thrilled customers!

If you think about it, is it the home builders fault that the houses we live in today are so inefficient? Is it the inspection process that is to blame? Do we need stiffer regulations to make every one conform? Or is it the home-owners who insisted on the least expensive home. I don’t believe that it is any one reason for the problem we have today, but rather we all have played a part in the inefficiency problems of today’s homes. It is not because of better technologies and techniques because they do exist. It is what we consider as important to us in a home that causes the rift. You know what I mean, the builder offered a free upgrade for custom cabinets or for only five hundred dollars more you could have R-39 in your attic. Which would you choose, probably the cabinets and so would most everyone else because who cares about insulation when you are talking about the home of your dreams.
The answer to this problem will take a collective effort on all parties. The home buyer has to be educated on what an efficient home is, and demand such homes. Home builders need to exceed current code requirements and follow up behind sub-contractors more carefully (police themselves; don’t expect the code official to do it!). The codes need to be stiffened to reflect higher efficiency standards, and codes enforced in full. All this leads us to the current way of doing construction as a whole needs to change, from the buyer to the end product.
A standard like BTU’S per square foot would help to establish a guideline for all parties to follow and would encourage healthy competition in the right direction. Imagine instead of the granite counter tops and hardwood floors being the topic of discussion at your neighborhood picnic, instead you discuss who has the lowest BTU’s/sq’ in your neighborhood. Probably not going to happen in anyone’s home but mine , but If you decide to purchase a house with a bad rating at least you have been informed, and can take action to improve your house immediately. Time and time again I meet homeowners that have no idea how their house is performing until we show up and test the house. Quite honestly neither did I before all this became important to me. The heart breaking part is I find major energy loss problems that have gone un-checked for decades, and the homeowners had no idea that they had these problems. Would it not make sense to test our houses at the time of purchase? I like how Alex Wilson sums it up in his article by comparing the current building industry to the failed auto industry. Are the American people ready to bail out the building industry? After all we continued to purchase cars that were inefficient even though the American car industry refused to change. Are we going to continue to purchase inefficient homes?

The "sticker" is simply a way to inform a buyer about some important aspects of a home. Surveys have shown that when consumers are informed of the value of building more efficiently (lower monthly utility bills, enhanced durability, increased comfort, better resale value, etc.), most choose to spend the extra $1000-2000 over a code-level house and get it back after just a few years via lower utility bills. Other surveys show people are starting to "get" what Fine Homebuilding, Sarah Susanka and others have been saying for years... better to build smaller and use the money saved to upgrade quality. As builders in my neck of the woods are saying, "If you ain't building green these days, you're working your way out of business." Me, I wouldn't build myself a code house... why would I try to dump that crap on somebody else and then have word get around?

The throwaway consumerist mindset affects housing choices just as much as any other product. Many builders who have tried to do the 'right' thing and build and sell quality housing that exceeds minimum standards have found themselves punished for their efforts in the marketplace.
In one case I'm familiar with from the late 90s, a builder was marketing 30 houses in a new development. Among several upgrade packages were two similarly priced: one for higher-end kitchen finishes and casework, one for higher r-values and higher-efficiency mechanicals. You can see where this is going...he sold about 12 kitchen packages and 0 energy efficiency packages.
On the flip side, I'll relate my take on a code seminar I went to last year. It was shortly after my state adopted the 2006 I-codes, and several of us (commercial architects) from the office thought it would be good to get an overview of the changes. We thought it was peculiar that the class was heavily attended by residential GC's, that is, until we got a little further into things.
Both the tone and content of the seminar were heavily weighted to the interests of high-volume residential builders. It was clear they were all there because they wanted to learn what the minimum code requirements were, because that is what they built to, and no more. They wanted to be damned sure they didn't spend money on anything that exceeded code.
I have always taken the approach that the code is the minimum. It is the lowest acceptable standard for safety and, less so, quality. 'Meets code' means you passed, not that you got an A+. Not that I ever had much interest in buying the sorts of houses high-volume spec builders produce to begin with, but after getting this particular insight into their mindset I certainly had my preconceptions reinforced.

I built my first "passive solar" home 40 years ago. It faced south and had way too much glass. We didn't know any better back then. My neighbor has studied and studied and bought all the books and become a green building expert of late. He just built himself a custom home. It faces south and has far too much glass. Just turning a building south and putting far too much glass in it doesn't make it "green" or "solar." Both terms have been hijacked for money by businesses and industries. They are, in essence, meaningless. If the stuff all over your green building is PVC then it doesn't much matter that's it's green.
I just inspected a "green" subdivision in Charlottesville. The "green" roofs have dried up and died - completely dead, all of them - over the summer. It's a work in progress I guess. I'm sorry, what was the question? Oh, yeah, house stickers. It's a good idea; can I get to be a certified, licensed sticker-applicator before everybody else if I slip a few thousand to Uncle Otto, cause that's how it's done here in Dixie.

I don’t necessarily think that a required yellow sticker on the door is the answer, but I do think that full disclosure should be required for insulation levels, HVAC systems efficiency, plumbing fixture flow rates, as well as window and door ratings to all prospective buyers of new homes. If the homebuyer has this information, it is up to them to make the informed purchase decision of what is important to them.
I suppose that it is ultimately buyer beware. Most buyers are not builders and do not know what to look or look out for. Bigger isn’t necessarily better. In most cases, bigger is just bigger, and quality is quality – either you have it or you don’t. I can only hope that the pendulum will again swing toward the quality side of things and get away from the bigger/cheap consumer goods mentality.

We've had the house on the market for over a year. So far, not one potential buyer has shown any interest in how the house was built, how little energy it uses or that the insulation levels are higher than currently recommended for our area. This in an area of the Colorado foothills where we routinely get 90+ inches of snow a year and temps can get down to -30F at night. Buyers, and their realtors, only want slab granite and stainless steel.
Until buyers start demanding, or are even conscience of the need for, well built, highly insulated houses that take advantage of solar design, builders are going to continue building garbage.

So what you are saying is to write an article like this you have to build something. What about the people buying these homes? I think a little common sense and some research has produced a good article. I have seen the residential housing industry first hand and walls get a framing inspection and rough mechanical inspections then hopefully someone insulates properly before the drywall crew covers it up, never to be seen again. The least expensive way to be energy efficient is insulation but only if it is done the correct way. Someone independent of the builder needs to get a close look before it is covered up and it should be tested after the drywall is up and the first coat of tape is on.

Homes must be verified to be built 15% more efficient that required in the 2004 International Residential Building Code and include additional features to make them more energy efficient.

Rain incursion may be the largest water problem in New England. It is also a problem here on the Gulf Coast. Here, solar heat gain and humidity play havoc with energy efficient designs ideal for the Northeast coast. An ideal design in Missouri differs from these. Southern California has completely different problems to solve.
On the Gulf coast, 2-foot overhangs are great in some cases, but don't replace low-e2 windows and a properly vented roof with a radiant heat block coating. Heat exchangers for replacement air are designed to swap heat, when we need to swap water vapor. A number of "energy efficient" design features used up north of here actually cause early house failure due to rot.
Raising the evaporator temperature on central AC systems, a goverment encouraged energy saving plan of a few years ago, was a disaster here, causing a huge waste of energy as people struggled to make their homes comfortable. Matters were made even worse with improperly sized units in many homes.
I do applaud an increase of information for home buyers. I recommend that all new homes include a regular inspection plan during construction by an independent engineering firm, with the full report provided to the buyer, and a contact in the engineering firm that can discuss the report with mere mortals.
Ultimately, it is the buyer's responsibility to choose. And it is certainly the buyer's responsibility to maintain the completed house properly. And the buyer still has the freedom to determine what that means, thankfully.

Who is to blame for getting want they want, when they want it, the customer and the person who sells it to them. The auto industry is the perfect example, if you ignore that your competitor is building a better product and fail to provide a marketable product, your company will be bankrupt.
For me Sterling sums it up perfectly, the customer is always right and deserve what they get.
"SterlingDevelop writes: Fellas,
Calls for government enforcement are a de facto subscription to socialism."
Yes why should I pay for things I don’t need or use like roads, schools, police, and government?
"You are in fact saying that the free market is incapable of determining what should be built, and that we need an agent of the government to mandate and enforce an arbitrary ideal."
Yes, why do we need a uniform building code?
A person should be able to sell what others are willing to buy. Regardless of the threat to national security, our money should go to drug lords and oil kingdoms.
"The free market is wonderful because it will provide what is really wanted with no other pressures."
Yes, I want what I want and when I want it regardless of the consequences.
"If the consumer wants an energy efficient house, he will specify that and pay for it."
Agreed
"If he wants a cheap house that maybe isn't as efficient, God bless him. He should be free to do so."

"The customer is always right. It's a policy, not a reality."
Agreed, if the customer fails to educate themselves then they are to blame for what they get
And it's a good policy.

As to usefullness, fully weatherizing and insulating all houses that use oil for heating would save more oil than we import from the middle east. Doesn't that sound like a good thing? for other fuels, efficiency means we don't have to find those fuels. Additionally, the money is saved for the life of the house, meaning huge savings.
Also, mortgage companies will give higher loans for well insulated houses - less payment to energy costs means more available for housing costs.
Saving energy through efficiency improvements is far cheaper in the long run (literally pennies on the dollar) than trying to mine the raw materials to produce it. The problem is the prospective house buyer has no input into this process beyond the price of the house. A builder has more incentive to put in fancy counter tops and inefficient furnace/hvac and insultaion than to spend money on efficiency, weatherizing and insulation because houses are marketed almost soley on fickle asthetics rather than function. It is primarily a marketing issue. Maybe to sell energy improvements you have to market the savings and what those savings can do for you in the long run (better loan availability, lower monthly energy payments, more comfortable house, etc).

I am not saying that there is a problem because the GC is in charge only that, as they are incahrge they must except the responsibility and blame. There are some very good GD's out there, but in my experience they are in the minority.
After 30+ years of experience and doing most of my own field work I have my own ideas as to why some GC's have these problems. Being "Green" or making more rules is not going to solve it.

To the person who says the buyer is always right...yes, and no. I only say no because we cannot expect a buyer or client to understand the myriad complexities of designing and building a new energy efficient home - let alone remodel one in the same way. I don't portend to know more than my doctor or attorney (although I can ask for second opinions). If a client wants a large west-facing 2-story window in a warm sunny climate, will I tell them that a standard insulated glazing system is good enough...no, and I do not expect my client to know this.
In a profession where a greater amount of technical knowledge is becoming more important, I feel strongly that educated, trained professionals (both architects, designers, and builders) have to be on the same field with their knowledge.
Clients come to us with either the explicit desire to have an efficient home or not...I think it is important for architects, designers, and builders to impart, at minimum, the best practices approach to sustainability into each project. Having a "yellow sticker" at the end of the day will more easily help every client realize in more tangible ways how they have invested their money, what the potential worth is - besides the beautiful house of their dreams ;-)
In the next 10 years when that house goes up for resale; being a drafty palace built according to 1970's (or even 90's) standards will probably not sell as well as the house with the easily recognizable "yellow sticker" with the high energy efficiency rating.

Who is to blame? Well, laborers are doing what they are told, whipped into a frenzy to get the current job done so the next one can move forward ASAP. The building industry is like the tower of babble. Everyone blames everyone else, and no one wants to listen and learn, never mind try and make it better. Next time you're at you're favorite end of the day watering hole marvel at the attitudes of tradesmen that scoff at and belittle their customers. Tragic.
Green building is not a fad, it is and will be a fact of life. Fortunately, those of us that don't realize this will be passed by and hopefully be taken out of the mix. Don't get me wrong, I work with and call as some of my best friends contractors and craftsmen. We are good people in a difficult industry doing a sometimes thankless job. But that does not release us from looking forward, or taking pride in building something that will LAST, that is energy efficient and when drive by it we don't have to look away in shame.
Historically industry is out for industry. Period. One only has to look slightly backward to see the disasters festered by unregulated industries. (Ummmmm, hello bank bailout, auto industry, air quality, water quality, workers safety....and on)
So if Joe Consumer wants to build a crappy inefficient house instead of saying "go ahead and god bless" maybe someone should take the time to talk to him. If responsible contractors did, there would be no need for the government to step in. I'm not holding my breath.
Posted: 10:26 am on August 31st
For the record government notoriously fixes one problem and inadvertently causing another. I would rather trust the local professionsals. They know best!

I like the energy use decal idea quite a bit.
At the moment, my wife and I are in the (unexpected) process of selling our house in Maine. It is an energy-efficient, passive solar house (please see link):
(http://www.finehomebuilding.com/item/4436/from-washington-to-maine-building-a-house-for-the-first-time)
The average cost of heating oil in our area is about $2200 per year (on a cheap year). Last year our house used about $500 worth of propane in conjunction with a passive-solar design and Icynene spray-foam insulation to keep the house at 70 degrees throughout the entire cold season. We also used a wood stove in the evenings.
So we are selling an energy-efficient house.
Of all the potential buyers that have come to the house only one has expressed ANY interest in the "green" features of the house. In Maine at least, an extremely oil-dependent place where one would think energy-efficiency would be of the utmost importance, it's basically a non-issue.
To hammer this home, we even had one agent tell us that "all new houses are this tight nowadays" when comparing our house to others in the area.
Our reply was: Are they?
Perhaps. But I seriously doubt it when I take a look at the walls going up around the area.
I suppose that the agent is doing me a favor by shedding some light on a huge problem, mainly that buyers believe banana-oil statements like "all new houses" are energy-efficient and then quickly move on to other issues.
A decal stating energy use would certainly eliminate this gross misconception.
I now think that buyers in general DO NOT care enough about energy efficiency to educate themselves in order to make a responsible house-buying decision.
We might think, let the buyer beware - after all they have to pay the fuel bill.
And that's true.
But everyone is effected by this sort of intellectual laziness whether it's the addition of greenhouse gases to the atmosphere or the expansion of dependency on a distance limited resources, it's a shared problem.
When I hear the comments of people looking at a house for sale in 2009 what I learn is that "good looks, big and cheap" are the important issues.
A house SHOULD be beautiful! It should meet the needs of the people who are going to live in it. And it should be affordable. I think these are givens.
But a house is none of these things if it is not reasonably energy-efficient. I think this is also a given.
And that so many buyers think that "all new houses" are equally energy-efficient is a serious misunderstanding.
I'm all for posting some decals.

Insulation R values are a valuable tool but are not the end all be all of keeping energy costs low. Even doubling the R values required by the code (especially with batt fiberglass) will not have a cumulative effect if air-sealing is not part of this system. Too many builders ignore sealing of the exterior envelope, as is indicated in the article above around windows, to make the most energy efficient building systems.
Good holes, i.e Windows, Doors, Walls tightness; is the best way to create an energy efficient home. $150 vinyl windows are not the way to achieve this regardless of their NFRC ratings. They will fail.
Testing of the system when implemented by a Builder who has decided to create an efficient home thru the use of quality windows, doors, air-sealing and HVAC is the only way to achieve any long term energy efficiency in a home.
Retrofitting old homes with "new" "energy efficient" windows is a band-aid at best and will be money thrown down a well for the most part. Education of the public may help but don't count on there being a critical mass of purchasers making the change to informed consequential home design and building.
The use of Green Building in the industry has become so abused that it is now for the most part feckless in determining whether or not a home is built well or efficient. And the illusion of payback over time can be demonstrated for some systems and product choices but these are few and often have too many variables to predict. One of the energy efficiency gurus that I have worked with over the years likes to point to a spot in the house and say "My house leaks right there!". He knows where he has controlled the movement of air in the house and knows that what he has put in place will work. There are far too few looking at this level of design or implementation. Don't fall into the trap.

Even well intentioned builders are often confused about "energy efficient" technologies that emerge with only advertising to inform. Negatives are only publicly acknowledged by a manufacturer when that supplier has found a solution to market. Realtors and developer salesmen are often the "experts" home buyers depend on for recommendations.
Bogus or marginally effective techniques and "innovations" such as methods to reject attic heat have never worked in the climates like the south but continue to be sold and marketed aggressively by the suppliers and trade magazines, often as "green".
I recently talked to one builder who was completing his own house with 1980's technology. Why? Partially due to cost but primarily because of fear that a new synthetic stucco, aluminum wiring, plastic piping, asbestos siding, mold, etc. will emerge "when more is known". The conservative custom builder was too busy trying to meet his schedule and budget to worry about sealed attics and geothermal heat pumps. Of course the home will be beautiful and he can and will sell it when utility and comfort concerns dictate. Ah the free market...
Posted: 7:43 am on August 31st
As first-time homebuyers, we did our research and nevertheless made lots of mistakes. That's how we learned the above. Our house is pretty new and nevertheless it leaks air like a sieve. It has lots of vapour barrier to trap & condense exiting moisture, though. The builder was clueless and cut corners, even though he did numerous politically correct 'green' things. Why builders obsess about trapping exiting moisture I shall never know. But they're human beings; turn them into government functionaries and they'll be even more careless and cut more corners.

In the mid 90’s in Washington State, special plans examiners and inspectors were required on commercial construction. They were certified. They were much like other special inspections (e.g. welding/steel). The BO required the plans examiner sign off prior to issuing the permit. And before final CO, the special inspector had to sign off.
Another barrier to enforcement is the knowledge of the BO in energy efficiency and the energy code. While they understand much of the principles, enforcing a detailed energy code requires knowledge just like enforcing structural codes.
Builders who spec or otherwise bid are under pressure to minimize cost and they tend to minimize where things can’t be seen (they better not botch that granite counter install).
Homeowners often direct design with emotion more than making sensible decisions. They tend to demand a house larger than they need. They demand that panoramic west view (damn the sun). They are struggling to get into a home for least cost (never mind the energy cost down the road) and may not realize that saving one or two hundred square feet will save a lot in construction (easily paying for some energy upgrades) not to mention energy down the road.
Designers/architects often have to bend to the whim of their clients (do you blame them?). But do they make suggestions for better design and construction? I think they often don’t (maybe for fear of turning their client off). They put R-21 in the walls and R-38 in the ceiling and use Low-e glass and call their design energy efficient.
Minimum code is not [relatively speaking] efficient. Codes make requirements out of common construction practices that are considered relatively economical using materials readily available in the marketplace. That is why the code is MINIMUM construction.
So if I build the ‘average’ house in Boulder Colorado (I understand it is in excess of 5,000 sqft!) to energy efficient standards, do I get to give myself and my family of 4 a gold star? While I much appreciate and respect the need to ‘be free to build what I want’, I think there is some degree of obligation to build only what I need.
Now that is a hard concept to really define. Who’s to say what one needs? As a general rule, though, I suspect the average family of 4 does not “need” a 5,000 sqft house. Maybe expensive houses should far exceed minimum energy standards; the owners can afford it.
Can we label houses with energy stickers? We aren’t talking about a refrigerator here which can be pulled off the shelf and relatively easily tested under what would be considered ‘normal’ or ‘expected’ conditions to give us an idea of how it would compare with the other model or brand. There are many many more things that affect energy use in a house. Energy efficient construction be an energy hog. It is the occupants that cause energy consumption.
I’m not saying there shouldn’t be an energy document placed permanently in the house. That is a simple idea and much better than doing nothing. It tells you what you have under the hood, so to speak. It’s a start. Maybe the document should provide an indicator that the house meets or exceeds minimum energy code.
It can get complex fast. Difficult to put a single number on it like on a refrigerator, but more information MAY not be understood by the homeowner. The intent to simplify and be informative can be a formidable task.
The trouble is … efficient house design is an entire package … not just wall insulation or an efficient furnace. It is windows chosen and placed carefully. It is good layout and arrangement of [appropriately sized] spaces that as a whole fit the site the house is placed on.
Posted: 10:48 am on August 29th
Of course it is still buyer beware and buyers aren't obliged to take notice of the information but a sensible buyer when trying to choose between two houses should be taking the information into account.

One answer to your question is that several city, county and state governments have initiated or proposed laws that (would) require some form of energy efficiency disclosure / audit of homes upon sale. There are different approaches. Home energy rating report by third party, energy use disclosure with different look-back periods, checklist disclosure of energy efficiency conditions of the home, prescriptive improvements that must be made and verified before sale transaction and others.
Many of these measures have only been put in place in the last few years and there's a growing list of government (local, state and federal) looking at disclosure requirements.
May be a good time to become a HERS rater.
Here are some examples I dug up; I'm sure there are more.
Enacted Requirements:
Austin, TX: Energy audit required of homes older than 10 years old.
Maine: Landlords must provide prospective tenants with energy efficiency disclosure on rental property.
Berkley and San Francisco, CA: Before resale or during remodel basic energy efficiency upgrades must be made. Proposal to require energy audits upon resale.
Montgomery County, MD: Requires sellers to provide buyers with home's energy bills. Originally required full energy audit but that aspect dropped due to enforcement/cost issues.
Proposal Stage:
Ontario Canada: Proposed bill requiring "home energy rating report" on homes before sale or lease.
Seattle, WA: Studying energy performance disclosure.
Denver, CO Studying energy performance disclosure.
Minnesota: Legislature considering residential energy disclosure.

The energy decal is a great idea, and I hope it won't be too long before we see them plastered on the doors of every newly constructed home. I just wrapped up an edit on Matthew Teague's article on green building certifications ―which is going to be published in the next issue. In that piece he touches on this subject. Apparently, The Energy Trust of Oregon and Earth Advantage (a regional green building program in the Northwest) have teamed up to begin assigning homes an Energy Performance Score. The label will list the home’s energy use, energy costs and carbon emissions, much in the same way that cars are assigned MPG ratings. This should help the consumer sort through the junk houses on the market. Does anyone have more information on this program or similar initiatives elsewhere in the country?

The information required on the 'sticker' is R value of insulation in the ceiling/roof, walls, foundation, floor and ductwork; U factors and solar heat gain coef. for windows and doors; efficiency of heating and cooling systems.
Insulation levels and window and door efficiencies were bumped up.
As far as practices go - the IRC 2006 addresses them too. N1102.4 Air Leakage - fairly complete list of air sealing locations that must be treated with caulk, gasket or weatherstrips.
I think where things fell apart - and perhaps what you saw - is lack of enforcement. I'd say most builders aren't aware of the finer points of what's required by the building codes. And for the most part, they don't get thorough oversight from inspectors. To conduct a complete insulation and air sealing inspection would take an inspector at least 2 hours on an average house.
The 2009 IRC upped all the requirements again and a couple of the new provisions specifically address the inspection/enforcement side. Builders who have never heard of blower door or duct blaster tests will get a rude kick in the kiester when their local official asks for the 3rd party documentation before passing his visual inspection. Yup, performance testing is on the way.
I did a assessment of the 2009 IRC and compared it to the Energy Star Home requirements for my local HBA. The 2009 code is almost on par with Energy Star.
Regular FHB contributor and building official, Lynn Underwood, has been writing about the 'green' aspects of the 2009 IRC in the "Code Green" blog at GBA. Check it out:
