I've been reading a lot of info from Europe on rock wool. It is claimed to be close in R-value to foam and much greener with open vapor. I am interested in using for exterior and basement insulation. Does anyone have experience using rigid rock wool? Thanks.

I attended a meeting yesterday in Wash. DC sponsored by DOE and titled, Transaction Process Summit, - intended as a first attempt to develop a strategic road map to help the residential transaction process recognize the value of high performance homes. Sam Rashkin of DOE led the lively discussion on the issues that surround the residential high performance home transactions. Champions in the room included representatives from government agencies, MLS, NAR, NAHB, Mortgage…Continue
No doubt if you follow energy or environmental issues, you’ve heard over and over again that the least expensive way to tackle our energy difficulties is through efficiency. One report from the American Council for an Energy-Efficient Economy (ACEEE) suggested that $168.6 billion could be saved through energy efficiency by 2020. Still, some of those close to the ground have heard horror stories on how the whole process is sometimes carried out in real life.
We keep running into these.

Any thoughts on economical solutions?
These are typically in a pre-Weatherized house.
I've been going to the RESNET conference at the beginning of each year since 2009. I also went in 2004, and I can tell you that it's a great learning and networking opportunity if you're in the home energy industry. Are you on the fence about coming to the RESNET conference this year? Are you not on the fence but just haven't registered yet? Even if neither of those apply, see…Continue

The International Energy Conservation Code (IECC 2009 and 2012) requires HVAC ducts to be tested to prove a minimum leakage. While many states and localities will adopt this code outright, it is likely that many will also amend it to allow inspection and sealing alternatives. Many HVAC contractors are bound to breathe a sigh of relief at not having to face potential failure and the subsequent looking for the 'leak in the trunk line' that will eat up their profit margins by the…Continue
Whether driven by a genuine desire to reduce their environmental footprint, or simply to insulate themselves against rising costs, energy efficiency is becoming a significant organizational goal for many companies around the country. In order to achieve these goals, businesses are looking for direction on how they can have their buildings’ designed and/or operated to consume as little energy as possible. Many have looked to the LEED Rating System to provide both the guidance for,…Continue
For a technician or auditor that works outside of the Oil Heating Industry, seeing a tank leaking in a basement can send you into a moment of shock. Then of course, the dreaded conversation with the Homeowner will cast a cloud. The key is to have a plan, and know what to do. The smallest amount of knowledge in this subject could make you the hero. Simply stating, "Call your Oil Company!" can leave them feeling helpless. Of course, that oil delivery company must know about a leaking…Continue
A building is not sacred. A church or a temple, no matter how old, or big, or beautiful, by itself is not sacred. It’s the attitude of the people and the things that people do in a building that make it sacred or not. I have met many people in the home performance field who quietly go about the work of…Continue

Energy benchmarking can unlock $9 billion in energy savings by 2020, suggests a recent report by the Institute of Market Transformation. Despite our lofty aspirations of energy independence and tackling global climate change, we are only beginning to implement the first step in the multifamily building sector – understanding our energy use. Multifamily housing has a number of characteristics that should make green retrofits an appealing investment, but only a fraction of the…Continue

After writing last week's post: "High CO Reading, Now What?" it occurred to me that not as many people out there: technicians, raters, or auditors; are up to speed on the age old firing rate calculation. I hope this simple procedure is easily understood as you may find it useful if you are working with negative pressure gas valves, with Energy Star Homes, or just simply forgot your manometer at the shop. I…Continue
