Parkview at Terwilliger Plaza is a new high-rise building that adds 127 Independent Living apartments to the existing three building senior living campus. Consisting of one- and two-bedroom apartments, the new building provides space for up to 250 residents.

Designed with respect for nature, the master plan sets a new benchmark for retirement living. Rich, minimalist silhouettes combine with warm classical elements to create spaces that are inspired, intuitive, and intimate. By using Passive House sustainability standards, Parkview will be progressive and highly energy efficient.

Designed for Passive House© Certification, this high energy efficient building is projected to use fifty percent less energy than current energy compliant buildings. The design also includes 100% continuous preconditioned fresh air circulation and will result in interior spaces that are substantially more healthy, quiet and thermally comfortable than conventional buildings. The building includes green living roofs, green living walls and solar panels.

RDH’s role on the project included building enclosure design-assist consulting services during the pre-construction stage and construction field review and testing services during construction. RDH also performed the PHIUS Verifier role during construction. Testing included air and water penetration testing of fenestration, whole building air leakage testing, unit compartmentalization testing, and HVAC duct airflow testing.
