How the GBA Site Displays Readers’ Names

Posted on April 28, 2017 by Martin Holladay

In early February 2017, the GBAGreenBuildingAdvisor.com web site developed a new glitch: our site stopped displaying reader's names properly when they posted questions or comments on the site.

Instead of displaying "Elizabeth Stanton" or "Pablo Picasso," the GBA web site started identifying new GBA readers as "N/A N/A" or "User-43289." More recently, the site has begun registering new users with aliases like "YellowFrog" or "RedSoxFan."

Vermont Utility Expands Heat Pump Program

Posted on April 26, 2017 by Scott Gibson

Vermont's largest electric utility is beefing up its campaign to get ductless minisplit heat pumps into the homes of more people as it expands its no-money-down pitch to consumers in its entire service area.

Homeowners who sign up get a heat pump from one of three manufacturers and finance the cost of the installation over 15 years, making loan payments from $49 to $81 per month for a single-head heat pump. There is no down payment, and Green Mountain Power says that heating bills in this Climate Zone 6 state can be reduced by between 25% and 50%. Maintenance is included.

Congress Weighs Changes to Rules on PACE Loans

Posted on April 11, 2017 by Scott Gibson

Congress will consider new legislation that tightens disclosure requirements for Property Assessed Clean Energy (PACE) loans used by a growing number of homeowners to make energy-related improvements to their properties.

New York Builder Wins RESNET Prize

Posted on April 5, 2017 by Scott Gibson

A house 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 in upstate New York has been recognized in this year's Cross Border Challenge for having the lowest HERSIndex or scoring system for energy efficiency established by the Residential Energy Services Network (RESNET) that compares a given home to a Home Energy Rating System (HERS) Reference Home based on the 2006 International Energy Conservation Code. A home matching the reference home has a HERS Index of 100. The lower a home’s HERS Index, the more energy efficient it is. A typical existing home has a HERS Index of 130; a net zero energy home has a HERS Index of 0. Older versions of the HERS index were based on a scale that was largely just the opposite in structure--a HERS rating of 100 represented a net zero energy home, while the reference home had a score of 80. There are issues that complicate converting old to new or new to old scores, but the basic formula is: New HERS index = (100 - Old HERS score) * 5. Index score among U.S. custom built homes.
