Like most sentient beings, I'm pretty much outraged by the news that Merrill Lynch handed out $4 - $5 billion in "bonuses" last month, knowing full well that the funds would ultimately come out of taxpayers' pockets.  The only reason Merrill was being bought out by BofA is that it had failed. 

My humble suggestion, which I sent to Barney Frank via email, is that Congress pass a tax provision for tax year 2008, setting the tax rate on bonuses paid by companies receiving TARP funds or being bought by companies receiving TARP funds, at 100%.

This would not only recoup the money, but we would also undoubtedly see the spectacle of at least a few Republicans in congress and their media mouthpieces railing against the confiscatory tax rate on stolen taxpayer money.

Like I said, I emailed Barney Frank, even though I'm not a constituent and that's a no-no (I did apologize at the end of the email for my deception).  It probably wouldn't hurt if Barney heard the same idea from some folks who actually reside in his district, and it might be even better if other Democratic reps got the same suggestion.

Since I managed to draw the ire of at least 3 people (at least one of whom clearly didn't understand the technology) with my last post pimping ground-assist heat pumps, I thought I'd give it another go, but this time I'd like to focus on another really cool high-tech, low-cost and low-work way to boost home energy efficiency.  Before I go there, I'd just like to offer up this link to those of you who find geo-thermal or ground-assist heating and cooling systems intriguing.  It's a cool savings calculator that allows you to plug in your location, home size, existing heating & cooling system info, and then shows you the annual savings on energy bills you could realize with a geo-thermal heat pump system.  Keep in mind that this IS a manufacturer's website, and the calculator doesn't take into account your personal energy usage habits; in my case, the fact that for 2 - 3 months per year I open up the house and run a whole-house fan means that I wouldn't save as much as they indicate.  But still it's a cool toy that can help you see the savings these systems could offer in your part of the country. 

Now, on to today's geek topic:  radiant heat barrier.

Basically what we're talking about here is aluminum foil that you staple to the framing in your attic, floor, or exterior walls.  It operates on the principle that most heat loss/heat gain is due to radiant transfer - heat moving through an object or air.  The "R-value" you see cited on insulation stands for "resistance".  Basically, that's what insulation does - it "resists" heat transfer, mostly through trapped air pockets.  It doesn't stop heat transfer; it just slows it down by trapping the heat in the insulation's air pockets.  And when it has trapped all the heat it can hold, it then "radiates" that heat out, in all directions.  That's at least one of the reasons why, in summer, a house that's been shut all day with the A/C off will still be hotter than the outside air when you return home at night - there's insulation and air up in the attic that's now releasing the heat it stored during the day into your living space.  The same thing happens in reverse during the winter, only now the heat trapped in the insulation is heat that's rising from your living space.

What radiant barrier does is reflect heat.  In summer, the heat in your attic is mostly radiant heat being given off by the underside of the roof.  A radiant barrier under the roof joists will reflect up to 97% of that heat back out so the attic space never heats up in the first place (and the insulation on the attic floor never traps it to release it later back into your home).

There are a number of radiant barrier products on the market now.  One that I have used successfully in several installations is Prodex, which is a layer of closed-cell foam sandwiched between aluminum foil on each surface.  It has an Energy Star rating.  I first used this product in a 100-year-old home which had closets tucked under the roof slope - one of them on the south side of the house.  So much heat radiated through the roof in the summer that the homeowners complained they couldn't sleep in the bedroom during hot weather.  They wanted to demolish the back plaster wall and sloped ceiling of the closet and install insulation, then close it back up.  But since insulation needs an air space to work effectively, and there was only about 6" of space from the back of the wall surface to the bottom of the roof deck, I told them I didn't think they would gain much relief with fiberglass batts.  So I started researching and found this stuff.  Working with it was easy - it's flexible, only 1/4" thick, can be cut with scissors and installed with a staple gun, and it has an R-value of 15.  With the space we had to work with, we weren't going to get even that high of an R-value with fiberglass.  We left air gaps between the material and the roof deck, and between the material and the wallboard.  By the time we put the last piece in, the temperature in the bedroom had dropped - by about 20 degrees!

Well, after that I was sold, and since then, I've recommended to every customer that we install the barrier any time we open an exterior wall or someone wants to insulate an attic or crawl space.  For one thing, it's easier to handle than batts or blown-in insulation and it works better, too.  For another thing, the cost of the material is only 50 cents per square foot, less if you are buying a larger quantity - this compares favorably with the cost of both fiberglass batt and blown-in insulation.  For those customers doing new additions, I've recommended it as a house wrap in place of Tyvek - it provides the same vapor barrier, but adds insulation and soundproofing as well.  And thanks to the energy incentives included in the bailout, if you install this stuff any time in 2009, you'll get a $300 tax credit.

As for myself, I'm planning on installing it next year in my own home.  I'm going to be installing it over the ceiling joists so that I get the winter benefit of heat being reflected back down into my living area.  We're going to screed down the top couple inches of existing blown cellulose to allow an air gap and then staple this stuff to the tops of the ceiling joists.  Then, we'll run 2" sleepers over the top of it, perpendicular to the ceiling joists, and install decking above.  The decking will keep the foil surface free of dust so the top refelective layer can do its thing during the summer - reflecting the heat of the attic up and away from my living area.  One of the reasons I'm installing this way is due to my only concern with this product - I would hesitate to place it in direct contact with the bottom side of a roof deck, or on top of a roof deck under the tar paper, because I worry that the additional heat being reflected by the product would cause shingles to deteriorate more quickly.  I don't think this is a problem if the proper air gap is allowed for and the attic is well-ventilated with a ridge vent, where the heat can flow up the gap between the barrier and the roof deck and out through the vent, but I want the winter benefit as well.  I'll be jacketing the water heater and wrapping the water pipes under the house with it as well.

So, for those of you who advocate "envelope improvements", this one's for you - though you'd still get better efficiency and greater energy savings with a ground-assist heat pump.

Word is that the first policy priorities of the Obama administration this spring will be economic recovery and alternative energy.  With that in mind, I'd like to ask my fellow blog-geeks for an assist in contacting their congressional representatives to make sure alternative energy plans don't overlook the following.

One of my personal hobby horses, as a remodel contractor, is green building systems. The technology that most interests me are geo-thermal (or ground-assist) heat pumps. These systems are appropriate for most parts of the country and offer the greatest energy savings and carbon reductions per dollar spent of any existing home energy technology. A geo-thermal heat pump uses 35 - 65% less energy for heating and cooling than a traditional furnace/ac or heat pump system. The biggest drawback is initial cost - the systems cost about double what a traditional furnace/ac unit or heat pump costs, mostly due to the need to drill or trench for the ground loop. Under the energy conservation tax incentives that expired in 2007, you would have received a measly $350 for installing one of these systems (with your additional cost being in the range of $5000 - $7500) - in other words, no real incentive at all. I've scoured the package passed by Congress recently, and could find no mention of tax credits or deductions for these systems. Yet they are the most affordable energy-reducing technology available to homeowners. A solar system that would reduce the energy you draw from the grid by a similar amount would cost $20,000 or more.
.
So I need help from all you blog geeks to impress upon your members of Congress the need to not overlook this technology, which is more in reach for most of us than anything else out there right now. I suspect this gets overlooked because it's not as "sexy" as solar, wind, or bio-fuel solutions - but consider: something like 15 - 20% of the nation's energy usage goes to residential heating and cooling. Systems that use half as much energy make sense no matter how our energy is being produced. When we make the switch over to solar and wind and other types of renewable energy generation, having these systems in place will help whatever energy we produce from renewable sources go that much further.
.
So, for those of you who aren't so bored by this wonkery that you've already stopped reading, the points to make are: biggest energy & dollar savings and carbon reductions per dollar spent, most accessable technology currently available for homeowners, time to recoup additional initial costs 5 years or less (at which point anyone using this system will have more money in their pockets - which is good for the overall economy - compare to the 20 years or more needed to recoup cost of home solar, by which time the equipment is worn out and needs replacement), carbon emissions reductions continue after initial costs are recouped, and the need for substantial tax credits/deductions or even low-or-no-interest loans to offset additional costs for installing the systems so more people can afford them.  What is needed are tax credits/deductions that would offset at least half of the additional cost of the systems - so anyone wanting to upgrade would still have to spend some $2000 - $3500 more, but could recoup that expense in savings on energy bills in 2 or 3 years.  For many people, this would bring the cost down enough that it would be within reach - at this level, if you had to finance the extra expense for one of these systems, your monthly energy savings alone would cover the payment until it was paid off.

So, can I get an assist?  I've already written my rep and senators, as well as the Obama team.  Hearing from other folks would help make sure this important technology doesn't get left out of the mix.

Stepping back from my periodic hysteria over how the campaign's going, it's looking more and more to me like Obama is playing it like a master. Now, I know a lot of us are bemoaning that Obama hasn't been hitting McCain harder with negative ads. But look at it this way: last week the Obama campaign signalled to the 527s that they are welcome to open fire. Up until this point, thanks to Obama telling them to step off back in June, the liberal 527s have been quiet. This has had two effects: 1) because there hasn't been any activity from the liberal 527s, the conservative 527s have remained relatively quiet. 2) because the conservative 527s have remained relatively quiet, it has fallen on John McCain to sling the shit himself. Essentially, what this means is that McCain has been burning through his media budget destroying his own biggest positives - his alleged integrity and honor - with sleazy, dishonest attack ads. He's not put any time into defining what a president John McCain thinks is important, what he would actually do as president, etc etc. And it's too late for him to do it now - that ship sailed for good during the Republican convention, which was dedicated to more of the same. At the same time, McCain's transparent dishonesty is starting to turn his "base" - the media - against him. He's no longer the "straight talker" open to talking to the media - that got cut off a month ago, right about when he really started to wallow in the shit.

So here we are, 6 or 7 weeks out from the election, and it's too late for McCain to pivot back to the themes of "honor and integrity", because his base no longer has his back. He's stuck with having to play the game the way he's been playing it for the past several months. Except now, he'll be throwing his shit against the veritable shit tsunami that's about to crash all over him from the liberal 527s. It's not going to be pretty. But I fully expect to see it, because the lib 527s have been sitting on the sidelines and keeping their powder dry for the past 3 months, and during that time, McCain has been creating numerous points of attack. Last week was Obama's Mr. Burns moment, when he turned to the liberal 527s and said, "Smithers, release the hounds." And now, the ripping of flesh is about to commence.

I don't expect for the Obama campaign itself to run ads that are bitingly negative. Then again, they won't have to. The 527s will take care of that. Obama has managed to remain above the sleaze thus far; he's just stood back and watched as McCain shit down his own leg. Has it cost him a few points in the polls? Yes, but that's reversible with the 527s doing the pushback. By the time election day rolls around, we'll have two candidates who have been smeared, but only one of them who has shit all over his own hands, while the other one will be the only one of the two who has offered up any idea to voters about what he will actually do if elected.

Next week will tell all. Already we've seen a couple of hard-hitting 527 ads surface - one from Planned Parenthood and one from a wildlife gorup on aerial hunting of wolves. I expect that these are just the tip of a very large iceberg.

Fear not, children, this game is not played out yet.
