YEARS OF EXPERIENCE
21

Aaron has extensive experience in the planning and design of mechanical systems serving institutional, federal, and industrial
buildings and campuses. He has performed numerous utility master plans which include the optimization of steam, hot water
and chilled water generation and distribution systems through detailed heat balance, life cycle cost, and hydraulic modeling
programs. Additionally, he has performed several building-focused energy assessments and HVAC evaluations.
