Case Studies

Case studies are a key method of sharing lessons learned from the field. Case studies here are drawn from exemplary projects around the region and the world. They are organized by two project categories. The first group, New Construction and Substantial Renovation concentrates on developer driven projects using a sustainability framework such as Green Communities or LEED. The second group, Retrofit and Limited Renovation examines projects undertaken between major reinvestment and recapitalization. Projects are owner and manager driven with limited scope.

The multifamily prototypes illustrate a ladder of performance leading to net-zero energy construction. They include townhomes, low-rise apartments up to three stories and mid-rise apartments. They are intended to provide development teams information on envelope and mechanical system performance during the earliest phases of a project. Each building type has a profile based on current practice, high performance and Passive House (PHIUS) standards to illustrate a ladder of performance leading to net-zero energy construction.

Certification Programs

Many of the case studies included in this section have participated in energy efficiency, health home, and sustainable certification programs. Project participation is identified by program logos on the sub-directory page.
