Sara Dodson Holmes, Secretary
While her decision to attend Skidmore College as an undergraduate may have been heavily influenced by its outstanding equestrian program, it was here she fell in love with theater, soon becoming involved in all aspects of stagecraft. Knowing she wanted to follow a career in architecture and design, Sara earned a Bachelor of Science with a self-determined major incorporating studies in technical theater, art history, and studio art.
At the University of Pennsylvania, Sara’s studies ran the gamut from historic preservation to environmental building simulation eventually earning a Master of Architecture at the Graduate School of Fine Arts (now called the School of Design).
Sara has been with Wyeth Architects since 2009 working on numerous residential and institutional projects. Prior to this she worked at Centerbrook Architects and Planners in Essex, CT where she was involved in many different project types including museums, independent schools, student centers, research laboratories, and athletic centers.
Sara is passionate about sustainability and is a LEED professional and recently earned her Passive House certification (Certified Passive House Designer). Her dream home is a converted barn.
George Penniman, Treasurer
George Penniman received his Masters of Architecture from the University of Virginia in 1986 and is licensed in CT, NY, RI, MA and ME. Through a rigorous training and certification process he has been awarded credentials as a Leadership in Energy & Environmental Design Accredited Professional (LEED AP) for Homes from the US Green Building Council and a Certified Passive House Designer / Consultant (CPHD/C) from the Passive House Institute in Darmstadt, Germany.
George is a member of the American Institute of Architects, USGBC, Northeast Sustainable Energy Association (NESEA), Passivehaus Maine and People’s Action for Clean Energy (PACE). He is a founding board member of CT Passive House and has a long history of board membership with local institutions.
With his wife, Anne, and their slobbery dog, Leo, he divides his time between their beautiful (and drafty) 1848 home in Essex and their beautiful (and draft-free) Passive House cabin in Maine.
I became a Certified Passive House Consultant (CPHC) at the end of 2011. It was my most demanding accomplishment since receiving my architect’s license in Connecticut in 1982.
I initially earned a diploma of Architect from the Ecole Nationale Supérieure d’ Architecture in Belgium, where I grew up. Afterward, I received a Master’s in Environmental Design at the Yale University School of Architecture.
Then I started designing houses, including several passive solar homes, was a contractor for a while, and for a few years worked for other architects until I opened my practice in Branford, Connecticut in 1986.
I have continued training, taking courses at the Harvard Graduate School of Design, among others. I am now certified by both the US and by the International Passive House Institutes, and a member of the New England Sustainable Energy Association. In addition, I am a registered Interior Designer.
Community involvement, another aspect of my career, has led me to give several lectures on renewable energy, both in Connecticut and in Belgium, to co- chair the AIA, CT’s Committee On The Environment for several years, and for a few years recently, to chair the Town of Guilford’s Design Review Committee.
Now, I specialize in Passivehouses and remodelings, all the way to Net Zero; and in “Near Passive houses”, that foster greater comfort and healthy indoor air quality, using very low-energy, including renewable sources (geothermal and solar), which also reduces the carbon footprint. It is often the better alternative for the projects I do on sensitive sites.
My latest Passivehouse won the 2015 Hobie Award for the “Most Energy Efficient house” in Connecticut. I have also designed many medical and professional offices, several restaurants, many condominiums and even renovated a state prison. Moreover, I have an excellent track record of getting variances for properties with difficult zoning problems.
Houses I designed are in various states including: Connecticut, New York, Massachusetts, Colorado, as well as in the US Virgin Islands, France, and Belgium. Some of my work has been published in This Old House, Food and Wine, The Hartford Courant, The New Haven Register, and Yankee Magazine.
Passive House Enthusiast & Educator
After a career in advertising, marketing and strategic planning, Alicia joined forces with Bill to co-found a design/build company committed to the adoption and creation of high performance and energy efficiency with a specialty in passive house and zero net energy. Their firm has received multiple Home Builder Industry Awards (HOBI’s) and was selected in 2016 as the Grand Prize Winner of Energize CT’s Zero Energy Challenge. Most recently, their own Zero Energy Passive House received a Merit Award in CT Green Building Council’s 2020 Green Building Awards and was selected by Green Builder magazine as one of their 2021 Green Homes of the Year.
Spreading awareness and educating people about high performance building and Passive House is a priority for Alicia. She was thrilled to be chosen as the recipient of the Connecticut Green Building Council’s Judy Swan Green Advocate Award in 2017. More recently, she has expanded her efforts to challenge conventional thinking about how we design & build multifamily buildings, especially for our most vulnerable populations.
Alicia is also proud to be a founding board member of the organization, Connecticut Passive House (CTPH). In 2019, she was hired as the Executive Director of the Connecticut Green Building Council (CTGBC), a position that has enabled her to promote better buildings for people and planet.
