CEUs: 3.0 AIA LU/HSW; certificates of attendance provided to all attendees

Attendees of this Pro Tour learned how this land was transformed from the site of a single-family condemned house to the site of 4 combustion-free, net-zero duplex homes. The team behind this infill project detailed the history and lessons learned, offering this as an example for municipalities looking for ways to infill for community, housing, and tax support without extending infrastructure.

After the opening presentation, the group toured the condominiums while hearing more about specific aspects of the design, construction, and systems. Each of the four duplex buildings features a two-bedroom unit and a three-bedroom unit; one-floor configuration on thermal slab; ASHP technology; high ceilings; and passive and active solar provisions. The homes’ superior envelopes include 10" all-cellulose double wall construction, with foam air sealants.  Attendees of this Pro Tour heard insights from the builders, architect, site designer, and owners.
