Solar Thermal: Types, Cost, and Investment

Posted on May 2, 2010 by Christopher Briley in Green Architects' Lounge

Hi, Everyone! For better or worse, Dan (Morrison) tossed us the keys to the blog, so we’re posting without a net, so to speak. Phil and I were very lucky to have a special guest for this episode: Pat Coon. Pat is co-founder of Revision Energy, and is well under way in starting a new company, Revision Heat. Pat brings to the podcast his in-depth knowledge of solar thermal design and installation, as well as his craft in home-brewing technology.

ACI Round Two

Posted on April 29, 2010 by Carl Seville, GBA Advisor in Green Building Curmudgeon

Expanding on my last post about ACI, here are assorted observations and amusing anecdotes about events, products, and educational sessions that I attended. Unfortunately, I was not able to attend as many classes as I would have liked.

Energy-Efficiency Retrofits: Insulation or Solar Power?

Posted on April 29, 2010 by Martin Holladay, GBA Advisor in Musings of an Energy Nerd

For our country to achieve the carbon emission reductions necessary to avoid a planetary catastrophe, many experts contend that almost every house in the country will need to have retrofit work that achieves deep cuts in energy use.

There’s a major stumbling block, however: deep energy retrofits are frighteningly expensive —in the range of $80,000 to $250,000 per house. With costs so high, many homeowners are asking: how long is the payback period for a deep-energy retrofit?

Now’s a Good Time to Replace Your Heating System

Posted on April 27, 2010 by Alex Wilson in Energy Solutions

If your heating system is old and inefficient, now is a great time to replace it with a new, high-efficiency model. There are eight months remaining to take advantage of the 30% federal tax credit that’s available for installing energy-efficient gas- or oil-fired furnaces and boilers, as well as air-source heat pumps.

Poll: Why Does Green Building Matter?

Posted on April 26, 2010 by Daniel Morrison in Green Building Blog

Everyone has their own reason for wanting to build green. A couple of years ago as a fun little experiment I asked people at Building Science Summer Camp what the most important aspect of Green Building was. I expected a pretty straight across the board "Energy Efficiency" answer. I wasn't surprised to get health, global warming, durability, and forest conservation as answers, but I was surprised that I got them so frequently.

Building Houses and Saving Energy in Nicaragua

Posted on April 26, 2010 by Martin Holladay, GBA Advisor in Musings of an Energy Nerd

There's a reason this week's blog is late: I just returned from a week in Nicaragua.

I'm posting a few photos from Central America. My next blog should appear on schedule at the end of the week.

Can We Make Comfort (and Energy Efficiency) Affordable?

Posted on April 25, 2010 by Carl Seville, GBA Advisor in Green Building Curmudgeon

I recently returned from my third ACI conference in Austin. Formerly known as Affordable Comfort, this get-together is another geekfest on par with Resnet, but with a broader appeal. Until recently, ACI was a relatively small affair, appealing to the narrow and evolving home performance industry. Attendance this year was up dramatically to almost 2,000 people.

7 Steps to an Energy-Efficient House: 4. Windows

Posted on April 24, 2010 by Betsy Pettit in Guest Blogs

Editor's introduction: With energy prices rising again, many homeowners are planning energy-efficiency improvements to their homes. But most people are unsure of where to begin, and even seasoned builders don’t always know which priorities should rise to the top of the list. Betsy Pettit, an architect at Building Science Corporation, recommends starting where you can get the most bang for the buck.

Poll: Why Do You Build Green?

HAPPY EARTH DAY!

Today everyone is talking about the things we talk about at Green Building Adsvisor every day — today we're fashionable!

We at Green Building Advisor want to know why it is that you have chosen to design, build, and remodel according to green building guidelines. Environmental reasons? Quality reasons? Moral obligation? Financial opportunity?

Earth Day + 40

Posted on April 20, 2010 by Alex Wilson in Energy Solutions

The 40th anniversary of Earth Day arrives this week to relatively little fanfare. We’re focused on other things: high unemployment, a moribund economy, residual sniveling over health insurance reform. But 40 years is an important milestone.
