radiant barriers


Residential energy conservation has stagnated somewhat in the last 3 or 4 years. I do not know what the dampers are, whether it is price or attitude for instance. New houses are a lot more efficient but the efforts to improve existing housing stock have stalled. Here is an article about those latest techniques.

http://www.nyserda.ny.gov/Energy-Efficiency-and-Renewable-Programs/Residential/Emerging-Technologies-and-Accelerated-Commercialization.aspx

Emerging Technologies and Accelerated Commercialization (ETAC) in the Residential Sector

Opportunities to achieve energy-efficiency gains in the residential sector beyond traditional building and retrofit techniques have been limited by underutilization of emerging technologies that are commercially-available, but face barriers to widespread adoption in the industry. Technologies and techniques such as solid state lighting, lighting controls, home energy management systems, smart-grid integration, micro-combined heat and power, and super insulation have proven benefits. But they have seen limited market adoption, due to obstacles such as upfront costs, consumer and builder awareness and the lack of infrastructure support, including activities such as supply chain development, sales training and installer certification.

The ETAC initiative seeks to address the barriers to market acceptance by facilitating in-field demonstrations and the subsequent technology transfers. Widespread, large-scale demonstrations will incorporate these technologies into energy-efficiency projects, where the savings potential will be monitored and validated. In parallel, other marketplace needs will be addressed, such as the development of a training curriculum for designers and specifiers, installer-certification standards, consumer-education materials, and maintenance processes. Following the demonstration period, results will be communicated to the marketplace via various means such as case studies, presentations, and webinars.

While this specific initiative is focused on emerging technologies in the residential sector, NYSERDA will also demonstrate emerging technologies for the multifamily and commercial/industrial sectors through parallel ETAC initiative

Yes I know there are many things that are wrong about Las Vegas. People shouldn’t even be there in the first place. The rape of the river that no longer reaches the sea. The rape of the pristine desert and the death of many Native Americans. I lived there for a year and there is also the cheesy nature of the culture. But when they do something right, you got to give them credit.

Nevada Energy Star Partners Demonstrate Peak Performance (Web Only)

September 01, 2012

Las Vegas may appear balmy and inviting with its sparkling pools and swaying palm trees, but those who live in Neon City know the truth: It’s too cold in the winter and too hot in the summer.

Unfortunately, hundreds of thousands of homes that were built during an amazing 50 years of rapid growth in the Southwest do not incorporate modern advances in energy performance to accommodate the wild swings of desert climate. As temperatures climb to 110°F in the summer, many homes leak large amounts of cooled air through gaps in ducts, roofs, windows, and doors. And when the frigid north wind drops the temperature below freezing in the winter, heated air escapes, leaving living rooms and bedrooms uncomfortably cold and drafty. While Las Vegans know their climate, they may not realize that they are paying to heat and cool the great outdoors.

The dramatic temperature shifts in the high-desert climate make Las Vegas an ideal place for homeowners who are looking to make their homes more comfortable and to save substantially on their energy bills. Funded in part by DOE’s Building America program, the Building America Retrofit Alliance is working with the Nevada ENERGY STAR Partners–Green Alliance (NESP–Green Alliance), and with Better Building Performance, a Las Vegas company, to upgrade two typical homes top to bottom. Their goal has been to show homeowners and remodelers how easy and effective energy performance upgrades can be.

Are PACE Financed Residential Energy Improvements Capitalized into Home Prices?

September 9, 2012

The FHFA believes that an unintended consequence of obtaining a PACE loan is to increase the risk of mortgage default.  The FHFA’s  logic is that if the green investments are not capitalized into home prices then the home owner’s equity decreases as equity =  sales price – debt owed.   Under these assumptions, the green investment doesn’t raise the sales price but does increase the debt owed. My recent research convinces me that this pessimism is false.  Here is  My letter to the FHFA. Here is my July 2012 peer viewed paper on solar panel capitalization effects in San Diego and Sacramento   dastrup-zivin-costa-and-kahn .

We need more regulatory scholarship focused on empirical work and hypothesis testing.  I have an incentive to say this because that is what I do.

Yes, you can get a backhoe and dig a trench around your house for relatively cheap but, it really is a waste of time. Parging the walls first pretty much means coating the walls to make sure moisture does not get behind the insulation that you are going to put up. I suggest using a modern basement epoxy of some sort and I recommend rigid insulation after you have done that. Rigid is easier to work with and you can make the whole project into an adhesive affair where you adhere the furring strips to the epoxied walls and then you adhere the foam board (or whatever) to the furring strips. Boom, you are done unless you need to paint them for someone else in the house that hates the color of the “naked” board. You know who I mean. Like the article says as far as the vapor barrier placement you have to call your local building code people cause I got no idea,

 

http://www.green-energy-efficient-homes.com/energy-efficient-basement.html

Exterior wall insulation inside the walls

Insulating outside your exterior walls is often too expensive or impractical in existing homes. You can insulate the inside of your basement walls but you may exacerbate the problems associated with moisture if you don’t do the job correctly.

Parging: If moisture is seeping into your walls, parge the masonry walls to seal any cracks and strengthen any weak or porous masonry. This will help prevent water from seeping in from outside.

Vapor barrier: Vapor barrier should be outside the insulation if you are in a hot climate and only cool your home; it should be on the inside if you are in a cold climate and are mainly heating your home. Consult your local city building permits department to find out what are the suggested or mandated insulation and vapor barrier configurations for energy efficient basements in your area.

Framing: If possible, leave a gap between your framing and the exterior walls, to prevent moisture from the masonry from causing wood rot in your framing. Use small spacers behind 2×3 studs, rather than 2×4 studs against the outside wall, and you’ll still have room to install the standard insulation for 2×4, 16-inch-stud construction.

Insulation: If there is any likelihood of moisture getting into your basement, use a rigid foam insulation rather than batt or other fiber-based insulation. Moisture seeping through exterior walls will dampen the insulation and reduce its R value significantly within a few years, so you’ll start with an energy efficient basement and in a few years be losing as much heat to outside as before the renovation. Moisture will not have much effect on the R value of foam insulation. Buy the highest R value insulation you can – you can get an R value of 6 per inch in some insulating foam sheets. If you want both insulation and waterproofing, you could consider having Icynene insulation applied to exterior walls after framing but before drywall is installed.

Other places you should insulate

A couple of other important things to consider about basement insulation:

  • In an older house, where a shower stall is already installed against an outside wall, check the insulation level behind the shower. A prior owner or contractor may have installed the shower without adequate insulation. If you are remodelling or can access the wall space behind it, inject foam insulation or otherwise upgrade the insulation. You’ll have more comfortable showers and you’ll cut down on overall heat loss.
  • Insulate the perimeter of your basement ceiling (an area called the ‘rim joists’), from the outside walls to about 16″ to 24″ from the outside walls, to prevent moisture from creeping in between the upstairs

Five Models of Energy Efficiency: A Guide to Beautiful, Energy-Efficient Homes

Five US builders are being honored for their exceptional achievements in high performance building at the second annual BASF Builders Challenge Awards.

Led by the U.S Department of Energy (DOE), the Builders Challenge is working with homebuilders across America to build a new generation of high-performance homes, working toward the ultimate goal of providing cost-effective, net-zero energy homes by 2030 for all Americans.

To qualify for the Builders Challenge, homes must meet at least a 70 on the EnergySmart Home Scale (E-Scale) — which means they must use at least 30 percent less energy than a typical new home built to code.

2010 BUILDERS CHALLENGE AWARDEES
Colorado Builder’s Net-Zero-Energy House Costs Just 7% to 8% More

Ecofutures Building Inc. developed four certified Builders Challenge homes (two with minus-three HERS ratings). These net-zero-energy measures represented only 7% to 8% of the total building cost.

See how they did it so cost-effectively >>

Treating the Home as a Whole System

By treating houses as a complete system, David Weekley Homes qualified 280 homes for the Builders Challenge with HERS scores averaging 67. The homes ranged from 1,500 to 5,500 square feet.

Windows and Doors in your residence are the fine line between Rehabilitation and New Build. To use Professional Speak, your house consists of an interior and an exterior envelop with insulation inbetween even if that insulation is only air. The whole goal of energy rehabs is to dramatically tighten both the interior and the exterior of the house and then increase the insulation where possible. This is a separate issue in a way from the energy consumption in the house itself. So when you get to the parts that move…eg windows and doors that is where the expense can climb rapidly. If you are a home owner, new windows and doors make sense BUT once you open the cavities shouldn’t you check the insulation and what about upgrading the wiring? Why not tear the whole thing down and start again? HMMMM

So if you are interested in new here are all the usual suspects:

Green Your Home for Winter: Apply Low-E Window Film

Jasmin Malik Chua, Jersey City, USA

If you haven’t socked away enough money for new, energy-efficient windows-or you’re a renter who doesn’t have the latitude to make major home improvements-consider applying one of several types of window film to your panes for instant energy savings.

A plastic film with low-emissivity (low-E) coating, which can reduce heat loss through old windows by 30 percent to 50 percent, provides a thin metallic coat the blocks off heat and ultraviolet rays. Apply the low-E film to the inside pane of your window to trap heat indoors in the winter. When the mercury begins to rise, flip the film over to the outside pane to keep the sun’s heat out of your domicile. Plus, according to Lowe’s, insulating window films will pay for themselves in less than a year in reduced utility bills.Do-it-yourself window film is available in rolls or in precut kits, but you might want to consult the professionals on very large windows. Here are some companies that manufacture energy-saving window films:

1. Bekaert

2. CP Films

3. Film Technologies

4. Madico

5. Plastic View International

It’s Jam Band Friday – http://www.youtube.com/watch?v=TChocbG_TTI

During the height of the summer and for most of the winter there are windows that you can probably do without. I hate windows. Even when you dress them up they are Energy Dogs. So here is an easy way to get rid of them. This only works for windows that move. Cut 2 pieces of plywood roughly 2 inches bigger than the window casement. Glue as much styrofoam insulation (R Board) as you can to each piece of plywood centered into the cavity of the window space. Drill 2 holes in each piece of plywood centered in the top and the bottom quadrant of each piece of plywood. Open the window so that the 2 panes are in the center of the window case. Fit the pieces of the plywood over the outside and the inside of the window. Insert long bolts through the two holes and tighten nut and washer to either the inside or the outside piece of plywood depending on which way you ran the bolts. You can even run a light bead of caulk around the two piece of plywood, the washer and the bolt head for complete air tighness. All done. Problem solved. Window gone.
