The installed price of solar photovoltaic (PV) power systems in the United States fell substantially in 2011 and through the first half of 2012, according to the latest edition of Tracking the Sun, an annual PV cost-tracking report produced by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
The median installed price of residential and commercial PV systems completed in 2011 fell by roughly 11% to 14% from the year before, depending on system…Continue

High initial costs can discourage homeowners from making large investments in energy improvements such as new heating equipment or insulation. Our Community Energy Services (CES) residential program tries to remove this barrier by helping identify available rebates as well as offering financing options such as low interest loans. Homeowners who complete a CES home visit qualify for a…Continue

When using ACCA's Manual T for register selection, there are several basic rules that are followed regarding location. Most guidelines revolve around room air circulation and stagnant air, as well as the equipment application (heating only, cooling only, or combination). Application is the largest determining factor when it comes to return air locations.
For heating only applications, a low return duct is ideal to bring back the coldest air otherwise stagnant in the room.…Continue
The most terrified I've ever been was was the time I got called to do a home energy audit of the haunted house-as-a-system down the street. I still shudder when I think of that night. Yes, it was nighttime. The caller who hired me, a woman with a sultry voice, said that was the only…Continue
Recently, the Obama government has sanctioned relief funds for people affected by the super storm Sandy as part of its LIHEAP or Low income Home Energy Assistance Program. According to the reports, around 284,000 homes have been affected in the catastrophe. The total financial loss estimated so far amounts to $88 billion. As a…Continue

In previous posts, I’ve explained how to incorporate smart phones and apps into energy audits (here and …Continue
Last Friday I had the opportunity to attend a webinar put on by Energy Circle titled “Hurricane Sandy and the Home Performance Industry: How Do We Respond?” Peter Troast, CEO of Energy Circle, shared that when he woke up on Friday, he felt the need to start a bigger conversation—thus a webinar was born. For being a last-minute idea, the webinar was a huge success with a lot of response, which serves as yet another testament to the great people of this industry.…Continue

This is personal. When I heard reports about rampant waste and abuse in the 2009 American Recovery and Reinvestment Act (ARRA) that turned out to be false, I thought of all the people I know who worked tirelessly to meet one goal of ARRA—to weatherize 600,000 homes before March, 2012—and it made me very angry. The men and women of the Weatherization Assistance Program (WAP) met and exceeded that goal, with minimum fraud, abuse, and waste. In fact, they reached 1-million homes weatherized…Continue
As I write this editorial in early October, the outcome of the election remains uncertain. That’s just fine, because it allows me to offer early advice to whichever candidate wins. Here are some recommendations based on my years with Home Energy.
The government plays an important role in lowering energy demand. If Americans expect the government to establish policies to regulate natural-gas fracking and power plant emissions, then it should also address energy efficiency. The…Continue
Building Science is not really science; it is more of a concept. While the concepts were developed by scientists the system itself is not really hard science. The concepts are generally employed by building analysts and construction professionals. While I consider myself a student of building science I do not consider myself a building scientist. I am simply a tradesman with special training. While some in the field might have different opinions about their role in this industry I am…Continue
Will new technologies democratize energy much the way the Internet did information?
Industry movement seems to point in that direction with the rise of the smart grid, time-of-day pricing, distributed solar, and the electric vehicle. Together these technologies offer a vision of a less centralized energy system, one where communities and households ‘vote in’ or shape the electric grid by how they decide to consume energy, a phenomenon also called the …Continue
A seldom practiced design procedure, equipment selection, has been part of the International Residential Code for many years, and local MA/RI code at least since 2010. This critical step is the second part of residential system design, following a Manual J load calculation and prior to the Manual D duct design. I think confusion around the dated manual has contributed to lack of use and enforcement. Whether you are installing an air-conditioner, heat pump, furnace, or boiler, there…Continue
I've been wondering lately why we're so hell bent on testing houses. After all, we're a bunch of smart building scientist type guys and gals, right? We may not be Joe Lstiburek's (for which our families and fiends, unbeknownst to them, are mighty grateful), but we have a working knowledge of air and moisture movement, thermal and pressure boundaries, various Deltas (T, P, and the rest), and all that other stuff BPI made us learn. We don't assess houses one day in Tallahassee, the next in…Continue
