Why haven't solar heat and photovoltaic panels been combined in one product?

The availability of appropriately oriented roof space for both would seem to make it a no-brainer to apply a thin film photovoltaic onto the cover of a solar heat panel. Sure, some efficiency of heat gain might be lost but you'd be getting electricity generation!

Any ideas?

How does the national Green Building standard rate vs energy star

I am a builder in Montgomery County Maryland. The County Council has mandated that by 2010 all new homes must be energy star rated. The bill also leaves the door open for alternatives that are comparable. I need to be able to have the information available for the Department of Environmental Control that compares a home that is rated by both Energy star and The national Green Building Standard to demonstrate that the national Green Building Standard would be a viable additional alternative for a builder to choose when building a new home in the County.

Advice for a Green Electrician?

I got a question from an electrician the other day, "What can I do to be a green electrician?"

Off the top of my head, I said:
1. Become well acquainted with energy saving switches for lights, fans, and heating/cooling equipment. Also learn about wireless switches for remodeling and programmable thermostats.

2. Learn how to pull wire through SIPs and ICFs as well as how to deal with spray foam insulation in framing cavities.

3. Don't complain about doing things differently. Look for opportunities to learn new tricks and set yourself apart from Bubba.

Stucco over Brick

I am working on a retrofit project that currently has a brick exterior.

I believe the assembly is:

Drywall, cellulose filled 2x4 walls, fiber-based insulating sheathing, building paper, brick

I thinking of gluing rigid foam insulation to the brick, adding a drainage plane and then stucco.

Does anyone know of a problem with burying the brick in the wall like this?

Thanks for the help,

- Ron

Great green products for a Habitat for Humanity home

I am designing a home for Habitat for Humanity in a mixed-humid climate. I am trying to find great green products to use while keeping our construction cost to under $35,000. Specifically, I am trying to find some good windows and carpeting, but any other material recommendations would be welcome.

Who Pays for Net-Zero?

Imagine a large home with a good envelope and enough PV or Wind Energy to "Sell the surplus".
Can or does "the Grid" really use the surplus?
Has the Zero Energy Home really "zeroed-out" its impact at the power plant?

solar home for sale

Great website! I am putting my 100% solar home on the market soon and wondered if anyone has suggestions of places to post it so that a like minded person can find it. It is a real nature sanctuary on my 5 acres and I want someone with a small footprint to come and fill mine. Thanks for your ideas!

This site looks great, how relevant is it to Canadian code and product avaliability?

I live in Calgary, Alberta and am very interested in green building and renovating. As I learn more, I realize that a lot of the information is U.S. specific. Any info would be appreciated.
