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
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
The Three Laws of Home Performance Contractor
A performance contractor must do no harm through action or in action.
A performance contractor must follow the principles of building science unless they are in conflict with the first law
A performance contractor must protect…
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

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

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…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
Denver, Nov. 1, 2012: GreenSpot Real Estate recently launched its “GreenSpot” eco-makeover program for existing-home listings, including a “window sticker” showing the property’s…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
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…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
