5 Things New Energy Efficiency HVAC Contractors Need to Know

1. Do not sell on Price! Use 'Simple Payback'

The price of High-efficient equipment will undoubtedly cost more money up front, compared to the minimum efficiency systems. Taking into account existing repair bills, utility bills, installation, and equipment costs, a high-efficient furnace, boiler, or heat pump will cost the homeowner less over the estimated 10-15 years of operation. When completing the 'Simple Payback' calculation, the high-efficient heating system in New England will… Continue

A call to Builders and Architects: Does the Homeowner Know You’re a Blowerdoor Virgin?

When setting out to build an efficient house, the elephant in the room is air tightness. Industry is resisting mandated air tightness testing if thresholds are introduced meanwhile building codes are ratcheting up efficiency on all fronts except air tightness. Having debunked the myth that “a house needs to breath” its becoming painfully obvious to any building scientist that the lowest hanging fruit on the efficiency tree isn’t geothermal but simply producing a more air tight…

80 percent of Minneapolis’s housing stock was built before World War II, but 40 percent of these homes have never upgraded their wall insulation. After investigating barriers to completing efficiency projects, CEE’s latest report, Energy Fit Homes, proposes awarding a certificate to homes that achieve basic efficiency standards.

Existing homes need…

Microgrid for Neighborhoods: How Soon?

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…

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.

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…
