asonan@buildingenvelopetech.com

Andrea is a licensed architect with over 20 years of experience working in the United States and abroad. Early in her career, exposure to vernacular construction in Peru influenced her interest in exterior envelope design and the role of thermal mass in passive performance.

Over the past ten years, Andrea has focused her practice on building envelope design, with extensive experience in both large-scale new construction and the restoration of historic mass masonry buildings. She specializes in exterior enclosure systems, with a strong focus on reviewing and evaluating thermal performance and waterproofing, including facade U-values, thermal bridging, hygrothermal behavior, and the continuity and detailing of water resistive and waterproofing systems to support durable, code compliant, and energy efficient building designs.
