Designing and Maintaining HVAC Systems for High Performance Green Buildings

Course Dates and online registration are available at the bottom of this page.

Course Description

This course examines cooling system characteristics, advanced dehumidification systems and ventilation control strategies that can be an important part of conserving energy, maintaining comfort, and controlling humidity in green buildings. Case studies will also be used that highlight re-commissioning items that result in significant energy savings. This course is designed to accommodate those not very familiar with HVAC that want to learn more and has enough detailed information about advanced systems that will benefit those more experienced.

Course Learning Objectives

Primary objective is for student to be able to design or identify HVAC equipment and practices that will minimize energy consumption and effectively control indoor relative humidity.

Objectives; Each student will be able to:

  • Distinguish the difference between sensible heat and latent heat.
  • Understand the importance of pre-treating outside ventilation air.
  • Use a psychrometric chart to determine the dewpoint temperature, moisture content, and enthalpy of air at given conditions.
  • Identify five air conditioning systems and operational methods that control humidity well.
  • Identify four methods of ventilation control that can provide adequate ventilation and conserve energy.
  • Identify at least two advanced dehumidification systems that work exceptionally well at dehumidifying air in an energy efficient manner.
  • Identify five cost-effective items to consider in re-commissioning that can have big impact on energy conservation.

Qualifications of Instructors

James B. Cummings is a Program Director at FSEC where he has been principal investigator for 24 research projects over 18 years. He has conducted field research in more than 250 homes and 100 commercial buildings, identifying air flow, pressure differential, HVAC, and moisture control failures. He has done extensive training in building science, combining his considerable diagnostic field experience into his training experience. Mr. Cummings holds an MS degree in Applied Solar Energy.

Chuck Withers is a Senior Research Engineer at FSEC and a hands-on building scientist and accomplished researcher (18 published papers). He has performed field research in more than 300 buildings. He is fluent in the language of building diagnostics – blower doors, duct testers, pressure mapping, and air flow verification – because he has performed a full range of tests on a wide range of buildings. He has seen how buildings fail and knows how to communicate that knowledge. He has presented at more than 40 conferences, workshops, and courses, including Florida Energy Gauge, duct leak test method, IAQ Diagnostics, and commercial buildings uncontrolled air flow courses. He has a BS degree in Secondary Education Physics.
