The data continues to look worse, and this video explains just how dire the situation is:

Builders haven’t historically been known for their marketing savvy, and many green builders have told us over the years that they have struggled with communicating the benefits of their advanced offerings to homebuyers. Recently, production builders like Meritage Homes and KB Home have changed the game, marrying cost-effective, high performance, resource efficient, solar-powered homes and sophisticated marketing strategies.

The “decarbonization” of America’s building is critical to reducing carbon emissions by at least 80 percent below 1990 levels by 2050, the amount scientists believe is necessary to avoid the worst effects of climate change. California, long a national and world leader in fighting climate change, is already beginning to take a look at how to reduce the carbon pollution from fuels burned inside buildings for space and water heating.

Researchers with ORNL’s Building Equipment Research Group are working with General Electric Appliances to produce a refrigerator based on the magnetocaloric effect. The ORNL team is also developing an air conditioner based on the same principle.

ONE OF THE KEY POINTS I drive home to students in my passive solar design classes at the Evergreen Institute is to design new homes and businesses around the Sun. Put another way, the passive capture of the solar energy for home heat should be the central organizing principle when designing a new home.

Better Futures Minnesota and Habitat for Humanity are opening used building-materials, appliance and fixtures stores within a block of each other on a mile of Minnehaha Avenue S. between 26th and 38th streets that feature retailers peddling used and recycled goods.
Better Futures opened at 26th and Minnehaha and also launched an online e-commerce site for reclaimed building materials. Better Futures, which employs 72 people, most of whom are re-entering the workforce from prison, also provides “deconstruction services” that a Hennepin County official said are cost-effective and environmentally friendly alternatives to demolition. Eighty-five percent of a building is recycled.
“We look at how to minimize construction and demolition waste going to the landfill,” said Paul Kroening, a supervising environmentalist at Hennepin County. “Better Futures is the only one providing deconstruction services, and it works well with employment training and improving lives.”

One year ago, in the September 2015 edition of Green Builder, I employed this column to draw attention to the issue of house size. In the process, I called out the then newly announced “official” NAHB show home, The New American Home (TNAH), which was set to open during the January 2017 Design & Construction Week trade show in Orlando, Fla.

I visited with Jay Edens, director of Rreal on a trip to the midwest last month. Edens has created an unlikely oasis of solar hope (i know that sounds cliche', but it's simply true) in the middle of rural Minnesota. Pine River. Population 900 plus or minus. The organization runs several different types of projects, from solar furnaces (wall-mounted passive solar heat) for low-income families on energy assistance (LIHEAP) to PV installations for community centers to educational outreach.

The connection between codes and the climate may, at first blush, seem oblique. However, the two are intricately connected. Codes are designed to make homes and buildings stronger, safer, healthier, and more durable. They’re designed to improve performance and energy savings. And in so doing, codes play a pivotal role not just in protecting lives, but the planet as well.

ALTHOUGH SOLAR ELECTRICITY and wind energy are growing by leaps and bounds, they only provide a tiny fraction of today’s electrical demand. As global supplies of fossil fuel resources decline and as concern over global climate change increases, however, solar electric systems could become a major source of electricity, along with wind and a host of other renewable energy technologies. But is there enough solar energy to produce enough electricity to meet our needs?

I’m not a millennial, but I find myself intrigued by many of the things that seem to drive the interest and attention of that generation—smart technologies, clean energy, the circular economy, and tiny living.

• PV systems installed in new construction tend to be small and have high incidence of premium modules (top chart)
• Nevertheless, residential new construction systems in CA were $0.5/W less than retrofits in 2015.

Reading the lineup for the next ULI conference, I had to do a major double take.
