Residents of Ankeny Row welcomed researchers from the PSU Green Building Research Lab (www.pdx.edu/green-building) that are  are investigating the intersection of energy use, outdoor air quality, and indoor environmental quality at Ankeny Row. The built environment consumes 41% of the energy produced in the U.S, in turn contributing 39% of U.S. CO2 emissions. While building energy consumption must be reduced, for a solution to be effective it must consider the impact on the quality of the indoor environment. Researchers at the GBRL are interested in studying Ankeny Row due to its combination of airtight building envelope design, advanced HVAC systems, and on-site solar PV electricity generation as well as its record of meeting net-zero energy consumption or better.  Researchers have recently deployed monitoring equipment that measures site environmental conditions, particulate matter levels, and carbon dioxide levels in and around the residences. The researchers are also measuring real-time energy consumption in each home. They expect this data to shed light on how indoor air quality, outdoor air quality, and energy use are related in high-performance building stock. For example, the GBRL researchers will analyze the data to observe whether degraded outdoor air quality drives changes in energy production, consumption, and indoor exposure to air pollution.

With the landscaping and all but the common room complete, we invited members of the media to attend a private tour of Ankeny Row.

We heard from some of the Ankeny Row owners, such as Francie and Michael Royce and Richard Benner, about their process for purchasing the land and hiring Green Hammer to help them complete this net-zero-energy community.

In late February, the partners of Ankeny Row began moving in! Here’s Francie cooking up a healthy meal in her new kitchen with custom cabinets made by Urban Timberworks.

Carol and John (their living room below), recent Peace Corps volunteers and world travelers, are excited to have a home base that produces all of its own energy.

Landscaping is next. Can’t wait to see the transformed courtyard!

This fabulous weather has been great for the Ankeny Row job crew. Here’s a behind-the-scenes look from the job site in early September.

Comfotube connection to supply box & fire sprinkler

Both the Zehnder comfotube ducting / supply box, and the fire sprinkler system will all be located inside the plywood air barrier above. In a “typical” building the air barrier would most likely be located at the flat ceiling plane so these mechanical systems would create a serious challenge to air seal.
