GENERAL DESCRIPTION OF SUBJECT MATTER FOR EACH LECTURE/DISCUSSION
|
Topic
|
General Description of Subject Matter
|
|
Basic building construction
|
Describe how the term sustainability applies to green building design. Recognize the difference between green build standards, codes and rating systems. Explain the basic concept behind the LEED rating system and understand the process required to earn LEED credentials. Determine which codes or standards may apply for a given project. Describe what type of site selection and system design components satisfy the requirements for commercial and residential green build certification.
|
|
Green building systems
|
Recognize the different materials used in basic construction and select the proper procedures and methods of construction for each. Describe the different insulation R values of common building materials. Relate the importance of fire dampers in construction; incorporate the different methods of construction necessary for a successful residential or commercial project. Forecast what part of a HVAC system needs to be installed during each phase of construction. Explain the importance of LEED certification.
|
|
Indoor air quality
|
Define the meaning of indoor air quality. State the HVACR technician’s role as it relates to indoor air quality. Identify various pollutants and pollutant pathways that affect indoor air quality. List several tools and instruments used to help measure and evaluate air quality. Set limits that guide when other professionals need to be involved in addressing indoor air quality issues.
|
|
Residential load calculations
|
Discuss the importance of a heat load calculation. Explain the difference between heat loss, sensible heat gain and latent heat gain. Construct a U factor for a building panel given the R values of the components. Construct a HTM given a U factor and a design temperature difference. Discuss the effect that daily temperature swings have on heat gain. Explain the difference that house orientation has on solar heat gain.
|
|
Duct design
|
List the three overall goals in duct design; list the different duct design methods. Discuss how to determine the duct system design static pressure. Explain the difference between design friction loss rate and the actual static pressure loss through a duct. Explain how a duct’s equivalent length is determined; use a duct calculator to look up the duct size, air velocity and friction rate. List the criteria for selecting grilles and registers.
|
|
Mini-Split Systems
|
Compare mini-split systems to conventional ducted systems. Explain the operation of a multi-split system. Discuss the concept of load diversity. Explain the operation of variable refrigerant flow systems. Explain the operation of a heat recovery system. Describe the piping procedures for mini-split, multi split and VRF systems.

ATTENDANCE POLICY
Regular and punctual attendance is expected of all students in all classes for which they have registered. Students absent or tardy (excused or unexcused) 15% or more may receive an “F” for the course or may be dropped from the course. A student that is compelled to be absent when a test is given, will petition the instructor, in advance, for permission to take the exam early. Prior to the last day of class, a student will be allowed to drop one exam from the required exams given during the course. Required work not completed by due dates will not be allowed to be turned in late without instructor approval. Students may be dropped from a class by the Registrar upon recommendation of the instructor who feels the student has been unjustifiably absent or tardy a sufficient number of times to preclude meeting the course's objectives. Persistent, unjustified absences from classes or laboratories may be considered sufficient cause for College officials to drop a student from the rolls of the College.
Always communicate with your instructor. If you must miss class: Either let your instructor know ahead of time or communicate with your instructor as soon as possible. Come prepared for the next class. An absence is not an excuse not to the do the work, readings, etc.
