Prerequisites: ARCH 227 or ARCH 543G. This course provides students a deeper understanding of the relationship between architectural design and active building systems. The topics include heating and cooling systems, electric lighting design, electrical energy systems, acoustical systems, building water supply, plumbing systems, and fire protection. This course is the second of a two-course sequence in building environmental control systems (ARCH 543G, ARCH 544G) focusing on active (mechanical/electrical) solutions.
