ORNL test of Agriboard R value:
http://www.buildinggreen.com

 

 

Agriboard is a SIP that uses compressed straw for the core instead of the usual foam insulation board.
Compared to conventional SIPs, it appears to have greater strength, higher fire resistance, and more thermal mass, but less R value for a given thickness.   The panels can be either 4 or 8 inches thick. 
The use of straw for the core and engineered lumber should reduce CO2 emissions compared to conventional construction.

The walls are nearly 10 inches thick and use engineered "I" beams with thin webs for studs -- this provides very high R values and low thermal bridging compared to conventional studs.  Blown in cellulose is used for insulation.
The total energy use is about 4000 KWH per year -- about 1/4 of this is supplied by the current PV rig, with more planned.
Many pictures are provided.  The house is located in Sheffield/Nottingham/Derby triangle.

Efficient Lighting

EERE on Types of Lighting

This is our families estimated saving in energy and GHG's for going to CFL's:
http://www.builditsolar.com
(A 224% return on investment, and 1 TON of CO2 per year)

It is a just plain no-brainer to use fluorescents and compact fluorescents.  They are far more efficient, last much much longer, and will save you a ton of money and greenhouse gas emissions.  

Most utility companies offer some form of rebate program for buying CFL's -- making it even more of a no-brainer!
Daylighting

 

Using daylighting not only provides better and more pleasant lighting, it saves energy and greenhouse gas emissions.

Some daylighting solutions...

LED Holiday Lights

Almost all of the usual places that sell holiday lights now sell the LED lights.  Prices still vary a lot, so it worth shopping around.  We got ours a Costco for about $10 per string.

 

LED holiday lights are safer (no heat), last  a very long time, and look great.  They also use much less energy and significantly reduce greenhouse gas emissions.  The energy saving can be 90% or more.

A typical 100 light LED string uses less than 4 watts!  They have an expected lifetime of 20+ years.  With the LED holiday light prices dropping, the payback period can be as small as a season or two (considering both lower operating cost and longer life).

A well designed gray water heat exchanger can recover a large fraction of the heat that would normally go down the drain in your shower, and some other hot water uses.

In a normal shower, you spend a lot of energy heating water from 50F or so up to 100F.  It flows out the shower nozzle, over your bod, and down the drain taking 95% or so of the energy you just spent heating it.  The gray water heat exchanger uses the heat in the drain water to heat the incoming water.

Good article on building and using “hoop house” greenhouses, which provide a very low cost per sqft greenhouse.  Some construction detail.  This technique could also be used for inexpensive sunspace for generating solar heat for your house.

Many other construction variations here: Sunspaces

Comment: This type of sunspace can be built very inexpensively, and can provide substantial heat to an attached house, and some plant growing space for some of the year.  The best idea for transferring the maximum amount of heat to an attached house is to 1) build the sunspace large, 2) include very little thermal mass in the sunspace, 3) transfer heat during the day, and close off house to sunspace connection at night, and 4) do something to keep the sunspace floor from absorbing heat (e.g. garden bark covered with black poly).   The sunspace can also be built as a quarter of a cylinder against the house's south wall, rather than the full half cylinder version shown above.

Onset Pendant Light Meter

This compact and self contained logger measures light intensity in lumens/ft^2  and temperature.   It will handle full sunlight, and you could correlate lumens/ft^2 to watts/m^2 to get a rough idea of solar intensity.  It has an internal battery, and requires no connection to computer during logging.  Case is a bit like a small pill bottle, and is water resistant.  Price is about $40, but you also need the coupler and software, which add many dollars -- so this option might be best if you have or plan to use other Onset loggers. 
Apogee Pyranometer

 

http://www.apogee-inst.com/pyr_spec.htm

 

I finally bit the bullet and got an Apogee Pyranometer in order to be able to measure sun intensity accurately.  The Apogee outputs 2 mv per watt/m^2 of solar radiation (so about 2 volts for full sun).  It is factory calibrated to 5%, and cosine corrected.  About $180 (ouch).  It works well with the Onset logger which will convert the voltage readings directly to watt/m^2.  So far, I have been quite happy with it, and have a number of projects planed for it.

More on Duct Sealing

AeroSEAL Duct Sealing System

http://www.aeroseal.com/index.html

 

This is a process for sealing ducts that works for the inside.  It will reach areas of the duct system that are built into walls or otherwise inaccessible. 
 

Here is a comment from the Greenbuilding Discussion Group ( http://www.buildinggreen.com/elists/gb_signup.cfm ):
"I have sealed many duct systems by removing the grills/registers and using UL-181 duct mastic on all the joints I can reach. I then seal everything accessible at the furnace that is accessible. Most of the time I get to below 6% (California code for new ducts) without touching anything else. If I don't get below 6% then I go to the duct runs that are accessible. Only very large duct systems, and those with ducts buried I can't get below 6%, but I'm usually close.
I know the person who developed aroseal, you have to do some manual work anyway with larger holes(grills/registers ?) and you will only get as tight as theoperator has time to sit around pumping more sealant into the ducts. It is a great process for inaccessible ductsystems that can't be sealed otherwise."

Snorkel and Scuba Underwater Woodstoves:
http://snorkel.com

 

Chofu: This is a simple, wood fired heater for soaking tubs. 
It uses a simple thermosyphon system to circulate heated water (no pumps, no electricity).  The full stainless steel case is a water jacket for efficient heat transfer.

Snorkel & Scuba: These wood stoves for heating tubs actually live in the tub water, so heat transfer is directly from the stove walls to the water.

(Thanks to Wolfgang for suggesting this!)

It seems like this might be a simple, and greenhouse gas friendly  way to add heat to a solar heat storage tank when there is not enough sun?

This is a pretty slick idea for heating water with heat generated from compost, as well as providing greenhouse space.
The thing that intrigues me is that you can apparently have working greenhouse space above the heat generating compost pile?

This seems like a pretty good idea for reducing summer heat gain on windows.  The shades block up to 90% of sunlight, and mount in vinyl frames (like bug screens).  It looks like they would work on a wide variety of windows, including ones that would be difficult to handle with other shading techniques.  They do the shading on the outside, where its most effect. 
It seems like a DIY version could be worked out.  The Phifer SunTex material is said to be available at some home centers.  Frames could probably be made from the same material that home centers sell for making insect screens.

A video from Science Channel on Plug In Prius:

(for high bandwidth connection)

 

A group working on developing the plug in hybrid -- a hybrid that plugs into the grid (or PV) at night to extend its range on batteries. 

The video gives a good overall description of the concept.  One might wonder how clean charging the car from the electric grid really is given that most electricity is coal plant generated.  The material on the CalCars website states that its cleaner than a conventional hybrid.

Transmittance of Corrugated Glazing

The Test

 

Do the corrugations in corrugated glazing (e.g. SunTuf glazing) reduce the solar transmittance compared to flat glazing?
Here is a little to test to find out.

In my view, the Energy Star program could be more aggressive, but its certainly a good place to start.  For example, they have no plans to require more efficient refrigerators until 2012 at the earliest -- let them know you would like to see a more aggressive approach.

HVAC Ducts in Conditioned Space

http://www.toolbase.org

 

Heating and cooling ducts running through attics and crawl spaces typically lose about 15 to 30% of the heat or "coolth" they carry to these unconditioned areas. 
By including the furnace and ducts in the conditioned space, and larger energy saving can be acieved.

"Home Run" Plumbing

http://www.toolbase.org

 

 

Home run plumbing systems run small diameter PEX tubing to each fixture from a central location.  Result is less installation labor, less waiting for hot water at fixture, and significant energy saving.

Planning the plumbing system to shorten the runs for the manifold to the fixtures also pays big dividends in not wasting hot water.

This is (I think) a really interesting and useful collection of passive solar home plans.
They came out of a competition that HUD sponsored in 1982 for passive solar home designs. 
These 91 award winning plans were selected from more than 500 entries by builders, designers, and architects.
This was a very active time in passive solar home design, and the plans show a high level of innovation -- a great source for solar home design ideas.

This is the first 30 -- rest to come as time allows.

EFIS provides a way to insulate on the outside of dry stack concrete (or other) structures.  This places the insulation outside the thermal mass, where it can be effective in smoothing out temperature variations, and in absorbing solar gain through windows (see entries above).

The links in the left panel provide information on the various EFIS systems, and details on how they are installed.  EFIS offers a wide variety of outside finishes for different looks.

EFIS systems could also be used to retrofit insulation to existing structures.

There have been moisture and mold problems with some EFIS installations, so be sure that you select a EFIS contractor with a proven track record in your area.
