The Time for Building Green Homes has Arrived

Posted on January 9, 2009 by Sam Rashkin in Building Science

The Link Between Energy Efficiency and Our Country's Best Interests Are Now Well Understood. Here's five reasons why the time is ripe to build and remodel green

In my last semester of architecture school, I took an elective solar and energy-efficiency course. My life changed immediately and forever. And now, almost 35 years later, it appears the building industry has caught up and it’s time for “green.” Why now? I’ve got five reasons:

Water Can Collect at Window Sills

Installing windows is tricky— A window is basically a big hole in an otherwise continuous surface that's insulated and protected from rain and wind.

Builders have been putting windows in walls for a long time, so there are plenty of time-tested methods. But old houses weren't insulated or air sealed as well as green houses, so drying was easier if the window leaked.

LED Lighting — Efficient Illumination Without Mercury

Posted on January 6, 2009 by Alex Wilson in Energy Solutions

Light-emitting diodes, better known as LEDs, are all around us — those little red or green indicator lights that blink at us from our stereo equipment, most new traffic signals, and virtually all new exit signs in commercial buildings. And if you’ve been to Times Square recently, you’ve seen way too many LEDs being used for advertising! We’ve all seen colored LEDs; what’s new is the use of white LEDs for indoor lighting.

Five Things You Can Do Right Now to Cut Your Utility Bill

Posted on January 3, 2009 by Matt Golden in Green Building Blog

Green building has become a poster child for everything from solar panels to bamboo flooring. While all aspects are of green building are important, the first step towards a green home is to get the core systems working properly.

At Sustainable Spaces, when we work with homeowners to develop a roadmap for retrofitting their houses, we emphasize getting the basics, or the infrastructure, done right. It might not be sexy, but it is the core of the house.

Building Scientists Meet for a Roundtable Discussion

Posted on January 3, 2009 by Michael Chandler in Green Building Blog

One of the advantages to being part of the GreenBuildingAdvisor team is an invitation to Joe Lstiburek’s Building Science Summer Camp (that's Joe, on the right, and me in the photo). This is an invitation-only gathering of 200 of the top building scientists, engineers, and architects in America. Of course, builders and remodelers are invited, too. I was there as a member of Peter Yost and Dan Morrison’s new GreenBuildingAdvisor project. Lstiburek is on the advisory team, too. The experience was absolutely amazing.

Heating and cooling the outside

Posted on January 1, 2009 by Daniel Morrison in Green Building Blog

What's wrong with this picture?

a) The air handler and duct work are in the hottest and coldest part of the house.
b) The wall insulation isn't working.
c) There's more insulation on the wall than on the ductwork.
d) All of the above.

I wonder if the people who live in this house have young kids. And I wonder if they ever say to those young kids "Close the door, we're not heating (cooling) the outside." I used to hear it from my Mom, and I'm sure most every other person since the cave man days has heard it too.

An Overview of HID Lighting

Posted on December 30, 2008 by Alex Wilson in Energy Solutions

Three recent columns provided a brief history of lighting, an overview of fluorescent technology, and a look at the challenges of improving streetlights. Following a side trip into the issue of “passive survivability,” I’m returning this week to illumination with an overview of high-intensity discharge (HID) lighting.

Unintended Consequences

I was listening to NPR the other day and heard a very interesting segment on problems in the paper-recycling industry.

It seems that the bottom has fallen out of the market for wastepaper to be recycled. The price recently fell from $150/ton to about $20/ton, making recycling very difficult from a financial perspective. The primary side effect of this is that more paper will be put in landfills until the market comes back up.

Making Houses Resilient to Power Outages

Posted on December 23, 2008 by Alex Wilson in Energy Solutions

The ice storm a week-and-a-half ago illustrated, all too clearly, the vulnerability of our homes. Hundreds of thousands of homes in New England lost power in the storm, which deposited up to an inch of ice on trees the night of December 11th, and tens of thousands were still without power a full week later, despite heroic efforts by utility crews. This illustrates why all houses should be designed and built to achieve “passive survivability,” an idea that, nationally, I’ve been advancing for the past three years.

Am I Hallucinating or What?

Posted on December 22, 2008 by Carl Seville in Green Building Curmudgeon

I got a press release in the mail today for a new product called “Doorbrow”, including the following points:

“…a revolutionary new product…” , “…will minimize water intrusion and sun deterioration…”, “…prevents leaks between a building and its entry door, effectively eliminating water intrusion…”
