Mechanical + Electrical + Plumbing + Technology Design
Energy Systems Design (ESD) is a client-focused group of mechanical, electrical, and plumbing engineers founded in 1988 in the Phoenix, Arizona area. Operating from offices in Scottsdale, AZ and Austin, TX, ESD has built its MEP practice over three decades to encompass technology integration and a dedicated design-build department. More than half of its engineers hold LEED Accreditation, and its staff includes ASHRAE Commissioning Process Management Professionals, Certified Energy Managers, and WELL Accredited Professionals. ESD incorporates sustainability into every project from early goal-setting through final building systems commissioning, with award-winning work spanning hospitality, higher education, mixed-use, government, and commercial sectors.
