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…

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
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

Many homeowners searching the internet for crawlspace repair information end up in home repair forums. While there is some good information out there, there are many examples of bad and outdated advice related to repairing crawlspaces. I have witnessed firsthand the results of unprofessional crawlspace repair and would like to set the record straight on what I consider to be the worst 5 crawlspace repairs I've seen.
1. Adding more foundation vents…
Una Bomba de calor es, a grandes rasgos, una máquina que se basa en un ciclo de refrigeración reversible. Este tipo de equipos tienen dos partes fundamentales, el foco caliente y el foco frío. Cuando se aplica energía eléctrica al sistema, uno de los focos aumenta su temperatura (desprende energía) mientras que el otro la disminuye (absorbe energía).

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

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
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

I wash, dry, and fold approximately 10 loads of laundry per week. It is a constant logistical challenge to allocate enough time for these sequential chores.
Imagine what would happen if it took twice as long to dry the clothes. I’d be frantically drying my kids’ soccer uniforms with a hair dryer, while they paced about in that “My world is ending and it’s all your fault!” sort of way that teenagers are famous for. What parent needs more…Continue
Much has been discussed over exactly what is an optimal water heater temperature level setting. Many sources, consisting of ENERGY STAR, offer the energy conserving elements of temperature levels of 120 degrees or lower. And yes, there are cost savings to be had, however realistically for those whose current setting is closer to the standard factory preset temperature of 140 degrees.…
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
I just put together a new infographic on the best two maintenance tasks homeowners can do with their water heaters. The best part is that they only take about ten minutes or so to perform! By checking these two things at least once a year will help with getting the full life out of ones water heater, as well as making it as energy efficient as possible.

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…
