EBP TECHNICAL BRIEF & CASE STUDY SERIES
EBP’s case studies and technical briefs are tools designed to offer information that’s both highly practical and highly credible in a concise, application-oriented way.
The first entries in these two series focus on the critical topics of balanced ventilation with heat recovery and heat pump water heaters. Check them out here.
ENERGY STUDIES and LESSONS LEARNED FROM EBP DEMONSTRATION PROJECTS
–Ecotope’s 2021 Energy Study on Sawara (Yesler Terrace 7.3)
–O’Brien360’s 2021 Energy Study on Hobson Place S.
–Ecotope’s 2020 Energy Study on Othello Square
—Perspectives and Lessons Learned from the HDC Exemplary Buildings Program (Housing Washington conference presentation, Oct. 5, 2021)
EBP GUIDELINES SERIES plus WORKSHOP VIDEOS & CHARRETTE SLIDES.
We hope the recommendations in EBP’s Guidelines Series facilitate standardization and replication of robust practices in the production of cost-efficient ultra-efficient affordable housing at scale. But it’s important to note that these promising practices are relevant to all housing, not just to “exemplary” buildings, and can help build better affordable housing generally.
1– Early Integrative Design. The charrette was led by Exemplary Buildings task force members Joe Giampietro of JRS Consulting, Becky Bicknell of Walsh Construction, and David Reddy of O’Brien360— here are the presentation slides used in the charrette.
>>> EBP’s “Guidelines for Early Integrative Design” document available HERE. <<<
EBP’s “Promising Practices in Early Integrative Design” virtual workshop was recorded and can be viewed here.
2– Wall Assemblies. The comprehensive performance goals defined for HDC’s Exemplary Buildings Program include performance targets specifically focused on the enclosure. Those criteria provided the framework for an intensive design charrette led by task force member Brad Carmichael of JRS Engineering. Participants developed several simple and cost-efficient common wall assembly designs.
The Wall Assemblies guidelines were explored in EBP’s first “Promising Practices” workshop. The virtual session was recorded and can be viewed here.
>>> EBP’s “Guidelines for Solar Integration” document is available HERE and the blank solar proforma template is HERE. <<<
The “Promising Practices in Solar Integration” virtual workshop was recorded and can be viewed here.
4– Domestic Hot Water & Water Management. The charrette was led by several experts. Exemplary Buildings task force members Marty Kooistra of HDC, Steve Gelb of Emerald Cities Seattle, David Reddy of O’Brien360, and Jon Heller of Ecotope were joined by Kelly O’Rourke & Melissa Levo of Seattle Public Utilities, Gary Klein of Gary Klein & Associates, and Shawn Oram of Ecotope. The formal guidelines document resulting from this charrette is in preparation; until then, here are the presentation slides used in the charrette.

5– Balanced Ventilation with Heat Recovery. The charrette was led by Exemplary Buildings task force members David Reddy of O’Brien360, Joe Giampietro of JGA Consultants, and Marty Kooistra of HDC. The formal guidelines document resulting from that charrette is in preparation. The presentation slides used in the design charrette have been updated recently and were used to guide our promising practices workshop; that revised slide deck is available here.

About Our Design Charrettes & Workshops
HDC’s Exemplary Buildings Program, led by a task force of remarkably committed local thought and practice leaders, champions development of housing that is simultaneously healthy, safe, ultra-energy-efficient and affordable.
We believe having standardized practices in place will help us more consistently and cost-effectively achieve our performance goals. To define those standardized practices, we’re hosting a series of intensive design charrettes and workshops focused on several technical areas (Balanced Ventilation with Heat Recovery; Domestic Hot Water & Water Management; Early Integrative Design; Solar Integration; and Wall Assemblies). Each charrette will produce a set of recommended guidelines for that particular technical area that the workshops will explore.
The guidelines are intended to streamline the process of building ultra-efficient homes and facilitate the affordable housing sector’s ability to achieve construction cost efficiency, quality, and durability while pursuing the ultra-efficiency performance goals of HDC’s Exemplary Buildings Program and the specifications for projects in King County, Washington. While driven by our commitment to exemplary performance, it’s our hope that the guidelines can be useful more generally, facilitating the work of anyone eager to build better affordable housing.
