Hurricane Sandy and the Home Performance Industry

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.…

What is and how we can use solar energy?

 Most of us know already that the price tag of electrical energy, fuel, natural gas, wood together with other energetics are continually increasing. For that base we must always ask ourselves can our house budget stand with so many expenses. Each single investment involves some amount of cash, however this isn't the end and besides investing every single single day by day or every year by year we pay for electrical bill, natural gas, wood, etc. Keep in mind that even with solar energy…

Book Review: The New New Deal Finds that “Weatherization Works”

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…

Editorial: Energy Efficiency Advice to the Next Administration

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…

Building Science is not really science

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…

Autumn Home Energy Checklist

Fireplace and Chimney

The fireplace is an absolute must for maintenance and inspection. Although fireplaces are not energy efficient for most case, they can be a money saver if you have a wood source. They are also most efficient when a number of people are in the same room as the fireplace.

Buildup from smoke is a recipe for disaster. Over time creosote is layered onto the tile liners of the chimney from smoke. It happens to be a highly flammable byproduct and…

'Energy democracy' becomes more real

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 …

Building Code: ACCA Manual S

     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…

Why Test?

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…

Speaking to the Heart and Soul of Home Performance

It was my first weatherization conference since becoming the editor of Home Energy. I remember sitting in the crowd listening to the opening speaker and being very inspired. We’re soldiers, I thought. Some of us are on the front lines—the weatherization workers—and some of us, like the staff at Home Energy, offer support from the safety of our offices in Berkeley. We are fighting for our nation’s energy security, and for the health of children and adults, and for the survival…
