ENRG 55B: HVAC Systems and Efficiencies

Program Description:

The Building Efficiency for a Sustainable Tomorrow (BEST) Center has developed a 4-semester program to prepare students to work as commercial building energy auditors. The Commercial Building Energy Analysis & Audits Program is divided into 15 modular courses designed for a community college level student. Courses are intended to prepare students for energy auditing, analyzing a building envelope and building systems for efficiency, employing appropriate tools for energy modeling and working with data, describing utility rate structures and demand response strategies, estimating energy savings and financial impacts, and integrating business development skills and concepts with energy audit reporting.

Content modules can be selected, recombined, or offered in a more compressed format for existing workers, or those that have some background in construction, architecture, HVAC, building operations or mechanical engineering.

Course Description:

This model course from BEST Center focuses on HVAC systems and efficiencies. The course asks students to consider configured HVAC systems types, system controls and identification of energy efficiency or conservation measures. In completing the course, students will be able to: 1Describe and compare various types of air side systems such as single duct, dual duct, multi-zone, psychrometrics, terminal units, etc. 1) Describe and compare various types of water side systems such as steam, condenser water, hydronic, cooling and heating sources, 2) Describe the fundamentals of various controls of HVAC systems, 3) Evaluate energy conservation or efficiency measures of HVAC systems, 4) Calculate the energy efficiency or conservation coefficients such COP, EER and/or SEER, 5) Examine and evaluate various energy efficiency or conservation measures as applied to HVAC systems, and 6) Calculate the amount of energy saved by implementing energy efficiency measures on both air side and water side systems.

The completion of the lesson in full takes 52 lecture hours (including 18 lab hours). Resources available as part of this course include a course outline, an extensive PowerPoint presentation.

For orientation purposes, viewers should begin with ENRG 55B_Course Outline.pdf, which offers a description of the course as well as an overview of topics covered through a course outline.

Course Contents:

The 3-page course outline document includes a course description, learning outcomes, and a detailed course topics outline. Topics include: 1) A Brief review of components, equipment and terminology from ENRG 55A, HVAC Fundamentals & Components, 2) HVAC system types, 3) HVAC system controls, and 4) Energy efficiency and/or conservation measures (EEMs or ECMs). Sections detailing the types of in-class and out-of-class assignments required and other textbooks and resources are also included.

The PowerPoint presentation covers all four topics introduced in the course outline.
