Microgrids may be the future of the North American electric grid, but when will that future arrive – especially for the homeowner? A team led by Ontario utility PowerStream is trying to find out with a new test project.
“A lot of the microgrid projects that you read about are typically large projects, hundreds of kilowatts, megawatts, running a whole university, a whole hospital, a whole military base,” said Mario Bottero, co-founder and president…Continue
Exposure to kitchen pollutants is a significant and overlooked health hazard in homes. The home performance industry pays great attention to protecting against exposures to combustion pollutants from water heaters and furnaces, but very little attention to an unvented combustion device that is used nearly every day: the…Continue
After years of telling friends, "When we remodel our house to Passive House standards we will use 80% less energy than similar homes in the area," and crossing our fingers that the data proved out, we are delighted to share with you our first year's energy data for living in Midori Haus.
What is Midori Haus? The name simply means "green house" since Midori is the Japanese word for green and Haus is the German spelling for house. The house was originally built in 1922, a…Continue
The U.S. Department of Energy (DOE) released the Home Performance with ENERGY STAR Sponsor Guide and Reference Manual (v1.5) (Sponsor Guide), a technical operations guide for the national Home Performance with ENERGY STAR Program.
First conceptually introduced at the 2012 ACI National Home Performance conference in Baltimore, Md., the Sponsor Guide is the result of more than…

Almost two years ago I posted a blog about the 2009 American Recovery and Reinvestment Act (ARRA); ARRA, or the “Stimulus Bill”, has gotten pilloried in the media as a colossal failure and waste of taxpayer dollars. But if you would take the time to do a little research, you would see that most of the coverage has been far from the truth.
Because of ARRA’s support for DOE’s Weatherization…Continue
An email came from Faith Morgan with a link to a documentary film called “Passive House Revolution,” produced by the Arthur Morgan Institute for Community Solutions in Yellow Springs, Ohio. It was a busy day, but I thought I could use a break from words, so I left the stack of unopened emails for a while and watched the film. I’m glad that I did.…Continue
There is a lot of news flow on investor interest on raising funds for solar loans, but not much attention has been paid to - what constitutes an ‘attractive interest rate’ to make homeowners ‘jump’ to make that solar investment.
Supply Side First
Lets focus on the resource side; the benchmark for raising ‘low cost’ institutional funds lies will be SolarCity’s…Continue
Weatherization is about more than just energy efficiency. It has always been about the health and comfort of the weatherized home’s occupants as well. For a long time these benefits of weatherization have been called “non-energy benefits.” But the health effects of weatherization have now taken pride of place alongside energy benefits. Now there is new research showing increased health and well being among families whose homes have been weatherized. A recent Home Energy article—available…Continue

An article published in the NY Times, titled, "How To Get A Job At Google" got me thinking about one of the most innovative companies in the 21st century. Google, the people who want to "organize the world's information", was named one of the best places to work in 2012 and 2013 not only because of the free food 24-7, but also because of their culture and the Googlers who work there. It is a place that many in the tech world aspire to work at one time or another. In…Continue

I run an energy program in the mountains of Colorado. We have a lot of homes without existing duct work and older style wall-mounted furnaces. I've been looking for a decent upgrade choice for my clients - so far Rinnai seems to be the brand of choice for most heating contractors. Problem is they have an AFUE of only .82 at the max, so don't qualify for high-efficiency furnace rebates through our program.
I recently discovered the Energy Saver 90 Plus from Empire Heating, a…Continue
In 2013, Boston earned the title of the most energy-efficient city in the United States from the American Council for an Energy-Efficient Economy (ACEEE). So why is the city outranking all others?
For one, the city implemented its own Climate Change policy, which sets energy-savings goals, such as reducing greenhouse gas emissions 25 percent by 2020, for the municipal government and the community. In 2013,…Continue
In 2013, we published a blueprint with the National Home Performance Council that outlines a seven-step…Continue
With the Google buyout of NEST thermostats, attention has turned from the “smart meter” to the thermostat as a focal point of residential energy efficiency. (Read this recent editorial by Alan Meier.) But several years ago Energy Star decided…Continue
If we want to make good, or great, home performance a reality for more people and families across North America, we must come to some agreement on standard retrofit packages that work. Not every house is the same, but we can agree on standards that can be widely, quickly, and efficiently applied to similar housing types. The home performance community has more than three decades of experience to bear on the question. Please add your voice to the discussion.
Join Scott Yee, PARR;…Continue

Attention Wrightsoft Users!
Have you ever completed a load calculation and it just seems like it was short of what you had expected? Particularly when you are first starting out with a tool, contractors can make mistakes. After all, we tend to learn "the hard way", right? In an effort to make software work, the companies tend to start with some default values that require adjustment. For instance, most have the duct system in…
Here is the offending thermostat. Check out the mercury switch under the dial! Thank goodness we don't make them the way we used to…Continue
Cleaning the condenser coil. This has always been the number one task that Service Technicians avoid at all costs when maintaining residential equipment. Maybe it is the nature of the fast paced business when the weather gets hot? Certainly could not be the lack of water to rinse the coil as there is almost always is a water spigot on either side of the home. I cannot figure out why, and this may be one of the largest aspects of seasonal maintenance that impacts the efficiency of…Continue
1. If you sign today, I will take $X thousand off!
This is a sales tactic often taken by a used car salesman. A Quality HVAC Contractor will price their installation with confidence, after finding a solution to fit the needs of the customer, and correctly sizing such equipment. I have no problem with "ballpark" numbers over the phone, as this can help sift through customers that are not interested in quality, so contractors do not waste time on what tends to be free…

I worked as a janitor at St. Camillus elementary school after school and in the summers when I was in high school. I enjoyed the camaraderie with the other high school kids I worked with, and the crusty Dutch man who was our boss. We cleaned every afternoon in the school year and on weekends, and then painted, cut the grass, and did maintenance on the heating system and other equipment in the summer. We took pride in our work, but we also had fun—once in a while playing a game…
Remember, though, improvements must have been installed in 2013, not just purchased, and generally, claims can only be made on your primary residence.
Eligible measures may include doors, windows, and…Continue
