Do Solar Panels Need to be Cleaned?

Posted on June 21, 2018 by Peter Yost in Building Science

I was at my brother’s house in Lee, New Hampshire, recently and looked up to see that his photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. (PVPhotovoltaics. Generation of electricity directly from sunlight.

His PV array is easy to get to — the long north slope of his roof has a walkable 5:12 pitch — so we went up and took a closer look.

Flatrock Passive: Firing Up the Heating System

Posted on June 18, 2018 by David Goodyear in Guest Blogs

Editor's Note: This is one of a series of blogs by David Goodyear describing the construction of his new home in Flatrock, Newfoundland, the first in the province built to the Passive HouseA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. Developed in the early 1990s by Bo Adamson and Wolfgang Feist, the standard is now promoted by the Passivhaus Institut in Darmstadt, Germany. To meet the standard, a home must have an infiltration rate no greater than 0.60 AC/H @ 50 pascals, a maximum annual heating energy use of 15 kWh per square meter (4,755 Btu per square foot), a maximum annual cooling energy use of 15 kWh per square meter (1.39 kWh per square foot), and maximum source energy use for all purposes of 120 kWh per square meter (11.1 kWh per square foot). The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.14. The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates. standard. The first installment of the blog series was titled An Introduction to the Flatrock Passive House. For a list of Goodyear's earlier blogs on this site, see the "Related Articles" sidebar below; you'll find his complete blog .

Where Can I Find Good Advice?

Posted on June 15, 2018 by Martin Holladay in Musings of an Energy Nerd

Donald Wulfinghoff is an energy consultant who works in Maryland. In 2013, he published Super House, a 700-page book that explains how an ordinary person without architectural training can design a superinsulated home that (he claims) will use only 10% to 20% as much energy for heating and cooling as a conventional home.

A Vision of the Future Takes Shape in Paris

Posted on June 14, 2018 by Susannah Shmurak in Guest Blogs

Every so often an environmentally friendly building gives us a glimpse of the low-carbon future so many climate plans envision. With the development of Clichy-Batignolles, the city of Paris has created a groundbreaking eco-village filled with such buildings. Begun in 2002, the massive redevelopment project is about 30% complete and is slated to be finished in 2020.

Simple Steps to Improve Air Conditioner Performance

Posted on June 13, 2018 by Allison A. Bailes III, PhD in Building Science

It's getting hot out there. Here in the Southeast, we love our air conditioning.  In fact, without air conditioning, far fewer people would live in places like Houston, Hattiesburg, and Sopchoppy. And that's true for the hot, dry places, too, like Phoenix, El Paso, and Boron.

So if we're going to have air conditioning in our homes, we want it to work.  It should be effective and efficient.  It should keep us cool without creating new problems, such as excessive noise, bad indoor air quality, or comfort that varies from room to room.

Designing a High-Performance Wall in Wildfire Country

Posted on June 11, 2018 by Scott Gibson in Q&A Spotlight

Will Welch has chosen to build his high-performance house in Nederland, Colorado. The site is at the border of Climate Zones 6 and 7, and it poses some challenges: it's at an elevation of 8,600 feet; the area gets a generous amount of snow and wind; and the number of heating degree days tops 8,800 a year.

But Welch has one more concern: the threat of wildfires.

Growing Marijuana Indoors is an Environmental Disaster

Many Americans live in areas of the country where the local utility sponsors energy efficiency programs — for example, one that offers homeowners free energy audits. In addition to offering this type of residential efficiency program, many utilities have also developed energy efficiency programs to help commercial customers, including retailers and manufacturers.
