AE 3422 - Building Mechanical Systems II3 lecture hours 2 lab hours 4 credits
Course Description
This course continues the development of heating and cooling systems design, by applying what has been learned in AE 3301 (Principles of Building Mechanical Systems) and the Systems-and-Equipment-intensive course AE 3421 (Building Mechanical Systems I). The course applies a systematic approach to the use of heating and cooling design as required by building simulation software currently used in the industry. An actual commercial building case study is utilized as a term project. In addition, the course covers the concept of Net-Zero Energy buildings. Upon completion of the course, the student will be able to comprehensively design an HVAC system in a real building using a building energy simulation program (Trace 700), and to produce all the necessary mechanical drawings. (prereq: AE 3421 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
- Identify the fundamental parts of building energy simulation structures and their hierarchies
- Define all heat gains and losses in a given building, and calculate the total cooling load and heating load of a building
- Apply the basic principles of fluid mechanics, to calculate pressure losses in ducts and produce an impeccable duct design
- Analyze and characterize different cooling equipment systems
- Analyze and characterize different heating equipment systems
- Analyze and characterize different cooling equipment plants
- Analyze and characterize different heating equipment plants
- Examine and relate the ASHRAE Standards to HVAC calculations and design.
- Examine and relate the utility rate structures to the building energy consumption and demand
- Design heat exchangers
- Calculate the life cycle cost of the HVAC systems
- Identify energy conservation, and renewable production, measures to reach Net-Zero-Energy building design
