We're Not Paying Enough Attention to Kitchen Ventilation

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…

ARRA Keeps Working for You

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…

Passive House Delivers 80% Energy Reduction in a 90-year-old House in Santa Cruz

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…

The Passive House Revolution

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.…

Solar Loans - what is the tipping point?

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…

More Proof that Weatherization Works—To Increase Kid's Health

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…

¿Qué es una bomba de calor?

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).

Which Communicating Thermostats are Consumers Most Likely to Use?

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…

New Boston Homes Generate More Energy Than They Consume

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,…

Standard Retrofit Packages—What Works?

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.

Drying Time Too Slow? A Dryer Exhaust Duct Power Ventilator May Help

By Trish Holder

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…

The Great Water Heater Temperature Setting Debate

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.…

What Is the X-Factor In Hiring In Home Performance

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…

90% AFUE Wall Mount Furnace

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…

Water Heater Maintenance in 10 Minutes
