Thomas Gentry is a licensed architect with extensive experience as a forensic and design architect, university professor, design-builder, general contractor, and tradesperson. His diverse experience and qualifications help our clients with complex litigation, mediations, and claims.

With a focus on building envelopes, Mr. Gentry’s experience as a forensic architect is wide-ranging and includes using transient coupled heat and moisture transport simulations to analyze moisture migration in wall and roof assemblies, providing critical examinations of high-rise masonry curtain walls, and preserving National Historic Landmarks. Mr. Gentry has also written about building envelopes and served as the American Institute of Architects’ representative on the subcommittee that authored the Chicago Façade Ordinance. Mr. Gentry’s experience as a design architect includes single- and multi-family housing, healthcare facilities, and commercial structures.

During his tenure as a Professor of Architecture at the Illinois Institute of Technology and the University of North Carolina at Charlotte, Mr. Gentry taught a wide range of material and building science courses, as well as design studios. Mr. Gentry’s research – which focused on a broad set of issues concerning social and environmental sustainability – was funded by grants from the U.S. Department of Energy, the National Science Foundation, and other sources, and was done in collaboration with faculty from engineering, anthropology, and other disciplines. Mr. Gentry co-led the development of a first-of-its-kind thermal active building system (TABS) that uses a modified capillary tube hydronic system and geopolymer cement concrete to provide heating and cooling with a low carbon footprint. His knowledge of these subjects has afforded him several unique opportunities, including testifying before the United States Congress Subcommittee on Energy and Air Quality.

Before acquiring his degrees in architecture, Mr. Gentry worked as a tradesperson (framing and finish carpentry), which led him to become a residential and light commercial general contractor, and then a design-builder. The bulk of his work involved housing, including multi-family housing, commodity single-family housing, and custom passive solar and earth-sheltered housing.

Mr. Gentry provides architectural services in the form of design and construction defect investigations, code analyses, standard-of-care analyses, and more. In providing these services, Mr. Gentry utilizes non-destructive and destructive on-site investigation methods (e.g., mechanical sounding of terra cotta, concrete, and tile; borescope investigations; sample extractions for laboratory testing); computer simulations and statistical analyses (e.g., transient coupled heat and moisture transport models using WUFI (Wärme Und Feuchte Instationär), statistical analyses of sample set sizes per ASTM E122 “Standard Practice for Calculating Sample Size to Estimate, With Specified Precision, the Average for a Characteristic of a Lot or Process”); comprehensive literature reviews of peer-reviewed publications, a robust personal building science library that includes hard-to-find and leading edge volumes; and other resources.
