Join AIA|DC and Capital Area CRAN for a tour at NetZeroRowHouse.  This reconstruction and expansion of an existing row house is a case study on applying Net Zero design principles on the scale of a family-sized urban infill home.  Heating and cooling, hot water generation, and cooking are all electric.  A ducted mini-split heat pump system, zoned on a floor-by-floor basis, provides superior thermal comfort and optimized efficiency.  Energy recovery ventilators provide abundant outside air that is conditioned to minimize heat loss and gain.  

A shared heat pump water heater provides hot water for both the primary residence and the lower-level apartment.  The award-winning kitchen features induction cooktops and smart appliances.  The 8 kW array solar array helps to offset onsite consumption.  Smart electrical panels provide insights into electrical consumption on a circuit-by-circuit basis.  Additional verification systems include air quality monitoring and water flow.  Rain water is collected for use in irrigation, and overflows onto a permeable paving garden.

Air infiltration is reduced with a combination of new doors and windows, spray foam insulation and a fluid-applied air barrier.  The exterior is composed of reusing the existing street facade, metal panel, thermally treated cypress, and nickel-gap cementitious siding.

Learning Objectives:

• Determine how ducted mini-split heating and cooling apply to different types of housing typologies.
• Learn how smart electrical panels can help verify Net Zero compliance.
• Become fluent in best practices regarding heat pump water heater installations.
• Discuss detailing to achieve blower door compliance.
