Prepares students for professional practice in building energy systems engineering, i.e., analysis and design of residential and commercial buildings, including district energy systems. Upon completion, students possess the skills to calculate heating, cooling, and ventilation requirements, as well as analyze, design, and evaluate integrated building energy systems to meet the following goals: indoor environmental health, safety, and productivity (codes and standards); economic drivers (affordability, life cycle cost), and societal needs (environmental equity, energy justice, decarbonization). Same as AREN 4110.
