Sean Groom, a former editor at FHB, leads it off with a discussion of how these windows were chosen, and FHB editorial advisor and builder Mike Guertin picks it up with instructions on how to install the windows correctly.

Is There Lead in the Water of Your Green Building?

Posted on March 22, 2017 by Stuart Kaplow

Worries about lead leaching from pipes and faucets into drinking water are not new. But the broad growth of "green" buildings, including schools, that use water conservation strategies has the potential to lower the quality of drinking water in their plumbing systems.

To reduce water consumption, the latest version of LEEDLeadership in Energy and Environmental Design. LEED for Homes is the residential green building program from the United States Green Building Council (USGBC). While this program is primarily designed for and applicable to new home projects, major gut rehabs can qualify. (LEED v4 New Construction) requires that indoor water use be reduced by 20%, and offers additional credits for reducing water use even further. But the consequences of that reduced water flow have ledLight-emitting diode. Illumination technology that produces light by running electrical current through a semiconductor diode. LED lamps are much longer lasting and much more energy efficient than incandescent lamps; unlike fluorescent lamps, LED lamps do not contain mercury and can be readily dimmed. to concerns about water quality in green schools across the country.

Energy Predictions vs. Energy Performance

Posted on March 21, 2017 by Kent Earle

Editor's note: Kent Earle and his wife, Darcie, documented construction of their superinsulated house on the Canadian prairies in a blog called Blue Heron EcoHaus. GBAGreenBuildingAdvisor.com published a number of those posts in a series that wrapped up last year. Recently, Kent wrote to say he has been monitoring energy use at the house and offered this followup.

My Net Zero Conundrum

By JEAN CARROON

Why would we want an individual building to be its own energy plant? This has never made sense to me. The scale seems inefficient and the potential of many existing urban buildings for net-zero energyProducing as much energy on an annual basis as one consumes on site, usually with renewable energy sources such as photovoltaics or small-scale wind turbines. (NZE) is limited. But many people I admire seem besotted by NZE. What am I missing?

CarMic House: Taming a Basement from Hell

Posted on March 13, 2017 by Carri Beer and Michael Hindle

Editor's note: Carri Beer and Michael Hindle are renovating a 1954 house in Catonsville, Maryland. Hindle is a Certified 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. Consultant and owner of Passive to Positive. Beer is a registered architect who has been practicing sustainable architecture for 18 years. She is an associate principal with Brennan+Company Architects. For a list of the couple's posts, see the “Related Articles” sidebar below. This post was written by Carri Beer.

From Red List to Ready List

One of the primary goals of the Living Building Challenge (LBC) is to eliminate the use of known toxins in products installed in the built environment. If it is harmful to life — human, animal or anything else — do not use it if at all possible.

In 2016, Wright Builders Inc. completed two Living Buildings, which will be evaluated for certification over the next 18 to 24 months. These projects gave us a unique opportunity to work inside the largely unexplored new world of materials research, vetting, documentation, and advocacy.
