This living laboratory is a home performance triple-play.

According to Bundle Design Studio architect Dan Welch, the Birch Case Study House was “developed as our business card.” Welch now lives in the home with his wife in the Birchwood neighborhood of Bellingham, in northwest Washington state. Welch had designed or consulted on several high-performance homes since leaving a traditional commercial architecture firm to start Bundle Design in 2014, but this was the first home he actually built.

Field Test: Ventilating an ADU for Optimal Air Quality

Posted by Matt Power, Editor-In-Chief

By combining an “always on” ERV and quiet bath fan this installation achieved above-and-beyond air quality.

One of the challenges with small “mother-in-law” apartments and accessory dwelling units (ADUs) is that they’re often built without adequate ventilation, or unbalanced systems that create drafts or fail to clear the air, or worse, haul other pollutants back into the building.

Habitat for Humanity’s Latest Housing Project Brings Green Affordability

Posted by Green Builder Staff

Nov 18, 2019 1:04:44 PM

Habitat for Humanity has an inspiring vision for its Depot Neighborhood begun in Traverse City, Michigan—to build each of the community’s 10 single-family homes to be truly affordable ones that harvest and produce all the energy they need over the course of a year, with the goal of eliminating homeowner energy bills forever.

To meet this goal, the Habitat affiliate decided to certify all 10 of the homes to the strict energy performance requirements of the U.S. Department of Energy (DOE)’s Zero Energy Ready Home (ZERH) program.

Zero Energy Construction is Front and Center at this Project

This high-performance project demonstrates carefully planned and executed planning and product selection.

Zero energy construction is front and center at the Lowry site in Denver, where Thrive Home Builders has constructed 34 single-family homes to the high energy-efficiency criteria of the U.S. Department of Energy (DOE)’s Zero Energy Ready Home (ZERH) program.
All 34 homes are expected to perform as zero energy homes—a home that makes as much energy as it uses—offering owners $0 in energy costs over the course of a year. DOE selected one of the 34 homes as a winner in its 2017 Housing Innovation Awards. The winning home achieved a calculated Home Energy Rating System (HERS) score of 4, with projected annual energy costs of negative $11 per year.
This home, like all 34 of the homes at Lowry, and like every home Thrive builds, is constructed to the DOE ZERH program criteria, providing a highly energy-efficient, solar-ready home.

A carefully planned design means a real ‘Revival’ for this multifamily project.

Homes built to the U.S. Department of Energy (DOE)’s Zero Energy Ready Home (ZERH) criteria can save energy and cut costs for homeowners. They’ve also been known to provide a more comfortable, quieter living experience. And, in Fort Collins, Colo., they may just be helping to spark a neighborhood revival.

Hot Water Heat Pumps Solve Title 24 Code Challenge

Posted by Green Builder Staff

Nov 6, 2019 2:36:11 AM

Changes to California’s Title 24 code allow heat pump waters to perform as a prescriptive option, balancing overall energy use for a home.

The 2019 Title 24 added two rules not found in previous codes. The first new item is Community Shared Solar or Battery System. This allows for a common shared system to offset any solar and/or battery requirements of a building.

Net-Zero Homes Take Building Science and Planning to a New Level

Posted by Green Builder Staff

Oct 30, 2019 2:20:07 PM

The 41 homes that make up Thrive Home Builders’ ZEN 2.0 Collection at the redeveloped Stapleton Airport site in northeast Denver are all net-zero energy, thanks to the solar photovoltaic arrays on each home, and a host of energy efficiency and high performance home features.

Like every home Thrive builds, these homes were constructed to the criteria of the ZERH program.

Thrive has taken the extra step of installing a 7.93-kW solar PV system, as well as an energy storage system. All of the ZEN 2.0 collection units come with enough solar panels to achieve a Home Energy Rating System (HERS) score of 15 or less (Thrive’s winning home here has a calculated HERS score of 4). Even without the PV system, the energy-efficient home would achieve a HERS score of 38.

Video: Turnkey Floating Stair Systems--Best Practices

Posted by Green Builder Staff

Oct 30, 2019 9:13:05 AM

This video outlines the installation steps for a straight Viewrail FLIGHT stringer and treads. This install was completed in one day.

This product design eliminates the need for on-site engineering. Viewrail has built thousands of floating stair systems. There is no on-site welding, no painting, and treads typically come finished and ready to install. Rod railing installs in half the time required for cable railing. A fab-on-site system typically takes several months to design, deliver and install. It’s a dramatic reduction in on-site labor requirements.
