It is commonly known that heat rises, if you need an example, open your freezer and see where the cold air goes. This same principle applies to hot air balloons; the hot air causes the balloon to rise. Many home performance professionals understand what this means for a home in the winter. Unfortunately, the average consumer may not understand how important this concept is. On average 60% of heat escapes through the roof of a house, attic or roof insulation can go a long way in reducing…Continue

When Home Energy’s part-time Associate Editor Leslie Jackson got home from a trip to New Orleans, where she did research on the rebuilding since Hurricane Katrina, she got a message on her phone. It was…Continue

It’s not easy being Green … even if you have a Ph.D. in the subject. Kermit was right, but I’m on a mission to prove him wrong.
Moving to a new home in mid-2008 presented a…
Yesterday I went to the Georgia Department of Community Affairs (DCA) for a meeting of the State Codes Advisory Committee (SCAC). Wait, wait, don't leave yet! I promise there's good stuff in here.
OK, let's try that again.
Yesterday I saw a bunch of guys sitting around a table make a groundbreaking decision that will alter the lives of home builders, energy raters, and utility customers. Yes, I'm talking about the great work done by the…Continue
As charging stations for electric cars become more widespread so will the use of electric vehicles. But the future is not based solely on building these charging stations for electric cars, rather on the advanced technology employed in them.
Charging stations for electric cars offer multiple charging possibilities to vehicles throughout the whole day. In many charging stations for electric cars today you simply plug in and begin to…Continue

While the following discussion (originally published in Climate Progress) extends to energy opportunities well outside the residential sphere, it's the latest example an overstatement of the so-called "Rebound Effect". Although there are certainly times that a portion of the…Continue
It’s no secret that windows are a liability when it comes to heat loss in homes. Conductance of quality insulated, low-e windows is typically 0.30-0.35 Btu/ft2hr°F, or about R-3. If installed in a wall that performs at R-20, heat lost through windows is 6-7 times higher (per unit area) than heat loss through the rest of the wall.…Continue

There is a hot and heavy dialogue taking place in an online group that I belong to, made up mostly of people who are in the business of auditing homes and then making homes more energy efficient, healthy, and comfortable. The main gist of the discussion is, Do we rely on the government to encourage people to make their homes more efficient, or is it up to the market? Does this sound familiar? Tune into any election debate in the…Continue

As we make homes tighter, we need to provide ventilation, which costs energy. One way to reduce the energy impact of that ventilation is to use an air-to-air heat recovery system. A heat recovery ventilator (HRV) recovers sensible heat by exchanging heat between incoming and outgoing airstreams. An energy recovery ventilator (ERV) is similar to an HRV but also allows moisture to be exchanged.…Continue

Home Energy Monitors, that is, devices that display a home’s energy consumption have been touted as Silicon Valley’s contribution to the national energy conservation effort. A Home Energy Monitor (or HEM) constantly informs the occupants of their home’s electricity and gas consumption, along with conversions to monthly costs and comparisons with previous periods. Some models can (or will) communicate with heating and air conditioning systems. These devices will…Continue

In a machine-driven, machine dependent world, power is the basic need. Power outage can bring all the activities to a grinding halt. Solar energy can provide a solid power boost to the bustling cities like Tampa, while helping the households and commercial establishments to reduce their carbon footprints.…Continue
