Senior Research Architect, Sustainable Technology Center at University of Illinois Urbana-Champaign

William B. Rose is a Senior Research Architect at the Illinois Sustainable Technology Center at the University of Illinois at Urbana-Champaign. Seichi Konzo, the principal author of double-wall superinsulation—the Illinois Lo-Cal House—was his university mentor. Mr. Rose’s university research is on energy and water in buildings. He is the author of the book Water in Buildings, and for 12 years he was the handbook chair of the ASHRAE committee responsible for the ASHRAE Handbook chapters on building envelopes. He is a founding member of ASHRAE Standard Committee 160 “Criteria for Moisture Control Design Analysis” and is currently involved in the ASHRAE guideline “Energy Efficiency in Historic Buildings.” He is known widely for tracing the history of building practices and regulation, which, for many people, demotes them from mythic status.

He has assisted many museums and historic properties with energy and water problems, including the Guggenheim Museum, Independence Hall, Angkor temples in Cambodia, and the United Nations Secretariat Building.

He is preparing a second book, on Architecture and the Performance of Buildings. This work involves tracing why the building delivery process is structured as it is, and why delivering performance meets so many impediments in the process. It involves envisioning the future and considering how the individual efforts of skilled designers and builders can begin to contribute to measurable improvements to global conditions. Joseph Lstiburek has called Mr. Rose “the conscience of the building science community”.

john sarter

John has studied construction methodology for most of his life. Early on the job training with specialty restorative builders trained him in the “art” of building from foundation and framing, to fine finish detailing. After apprenticeship and leading to a Journeyman’s Certification at Carpenters Local 35 in San Rafael California, John went on to study drafting and architecture and sustainable architecture in particular at Santa Rosa J.C. and Sonoma State University at the SSU Environmental Technology Center, under the tutelage and on the site of one of the earlier NZE projects by Architect George Beeler of AIM Architecture.

John’s independent studies programs through college resulted in design and development of his first design/build projects in Bodega Bay, Ca. in 1986, and he has continued to refine his craft in numerous residential structures continuously since that time. Continued education in energy use, abuse, and development, and through this the realization that the human / energy equation is very much out of balance has led John to the pursuit of structures that are self supporting and self sustaining, and now to net-positive building systems development. The understanding that this is an evolutionary process leads him to continual inspiration in expanding the boundaries that building science and technological advancement can and will perpetuate.

John feels that it is a societal imperative to create solutions that begin to solve more problems than they create, in order to work towards undoing the damage that the expansion of humanity and industrial growth has contributed to. This has led him on one of many tangents, through various channels and interconnected meetings with key individuals, to Passive House methodology as a powerful tool for energy reduction in the building systems and solutions his firm and colleagues are committed to developing.

Sylvia Wallis

sylvia wallis

As a practicing architect, a certified passive house consultant (since 2009) and LEED AP BD+C based in Los Angeles, Ms. Wallis is particularly focused on facilitating an effective migration of Passive House strategies to Southern California. She has initiated the development of the nascent community of Passive House enthusiasts in Southern California so as to enable the type of information- and experience- sharing that has occurred so successfully in the Bay Area. With common state jurisdictions and utility commissions, sharing in addition between Northern and Southern Californians can only prove beneficial.

Ms. Wallis’ background in sustainable design stems from her undergraduate years at Berkeley in the 1980’s. She returned to the Bay Area in 2009 to complete her Passive House training with several current and former members of the PHCA Board. She has consulted on various Passive House projects in Southern California for both individual and developer clients. Continuing training in Passive House approaches has included attendance at the annual national conference and participation in Therm training, as well as incessant reading of articles. She has maintained her ties to her Bay Area Passive House colleagues through attendance at various PHCA seminars and tours, as well as collaboration and peer review of Passive House project issues.

An architect with Harley Ellis Devereaux, her practice centers on sustainable design for educational, civic, and cultural facilities, integrating various energy modeling and performance simulation applications into the design process. Her focus as a design architect has been to respond to, interpret, and enhance the sense of place associated with each project, whether historic, bucolic, or industrial. In its respect for environment, Passive House has become for Ms. Wallis an integral aspect of design that sustains a sense of place.

zach whitt

zach whitt

Zach grew up building just about anything you can imagine out of wood: airplanes, decks, houses, instruments, and, most recently, surfboards. After studying Hydrology at Colorado State University, he worked in the field maintaining off-grid weather stations to monitor snowpack, but missed the head-on-hands-on problem solving woodworking always seemed to offer. He has since transitioned back to construction, most recently obtaining his Passive House Builder’s Certification and working on incredible projects in the Colorado area. When not tinkering with your windows and doors for optimum performance and operation, you can find him making sawdust in the woodshop, backcountry skiiing, pickin’ a guitar, mountain biking, chasing trout, or building his tiny house.

As Zola Windows’ Lead Technician, Zach has the pleasure of traveling around the country (and sometimes the world) to assist with incredible Passive House projects in both the design and build phase, helping builders and architects integrate high performance windows and doors into high performance buildings. He has had the unique opportunity of seeing a multitude of projects from a variety of architectural and building styles, giving him well-rounded insight into quality window installation.
