The engineering behind RUHLai
German roots. New York perspective.
RUHLai draws on the experience of RUHL TecDesign LLC. The New York-based MEP practice combines German roots with decades of hands-on engineering.
RUHL's work spans residential, commercial, and industrial projects on four continents, focused on efficiency, renewables, and fossil-free systems. In 2022, RUHL designed a steam-to-heat-pump retrofit concept for a New York City residential high-rise through NYSERDA's Empire Building Challenge.
RUHLai puts that expertise to work, helping owners understand their buildings and plan what comes next.
