Ken Neuhauser, M.Arch, MSc, Arch, CEM, CPHC

President

Ken has over 20 years of building science and building performance experience. Ken is a technical expert of hygrothermal dynamics within buildings, specializing in building enclosures for both new construction and retrofits. He brings a wide perspective that building performance includes many factors, including durability, economic impact, environmental impact, risk management, comfort, operation and maintenance. Ken leads the BEC team through enclosure assessments and investigations. He engages with design teams to achieve performance
objectives.

Ken’s past experience includes serving as technical lead on the National Grid Deep Energy Retrofit (DER) Pilot (2009-2013) in MA and RI., guiding retrofits of more than 40 buildings and achieved average measured post-retrofit performance of 22 kBtu/sf-year. He was a principal author of the MassSave DER Builder Guide. He led several Building America Program research projects focused on retrofit including a masonry wall retrofit pilot in Chicago.

When Ken is not examining existing buildings, guiding construction details or diving deep into building plans, he enjoys his family and being active outdoors. Ken lives in the vibrant community of Maynard, Massachusetts where he participates in various commissions and committees and is often found covered in sawdust and conducting the evolution of his own 100+ year-old home.

Jerry Townsend

Office Administrator

With over 20 years of experience in hospitality and office management, Jerry returned to school to follow his interest in architecture.  In December of 2023 he graduated from the Boston Architectural College with a Bachelor of Science in Architecture. During his time at the BAC, he developed a passion for affordable housing that drives him daily to discover unique ways to design and build not just the physical structure of the building, but homes that represent the lives spent within that building.

Jerry believes that energy and food security are integral components of affordable housing.  In 2020, he became certified in Permaculture Design to create a whole system design approach to developing sustainable housing.  He joined the BEC team in 2024 to explore and learn more about the importance of building science and how it can assist with creating long term affordable housing.

In his free time, Jerry practices permaculture with his personal gardens, and mills timbers from his property to learn firsthand how to build with traditional timber framing.
