Credits: .7
Lecture: 6 hrs
Group Exercises: 1 hr
Total: 7 hrs

Prerequisites: None

Class Description: Participants will learn the theory, design, and operational practices for new HVAC equipment technologies being installed in high performance buildings and calculate total cost of ownership to help building owners comply with energy codes and meet building energy management goals. Participants will learn the theory, design and operational practices for energy recovery from air and water source systems to determine applicable methods for capturing heating and cooling energy before it is vented or wasted in their building.

PROJECT: None

Learning Objectives:
At the completion of Energy Efficient Ventilation Strategies and Energy Savings through Energy Recovery a participant will be able to:

  1. Describe HVAC equipment being deployed in high-performance buildings (e.g., condensing boilers, ground-source heat pumps, chilled beams).
  2. Explain advanced control sequences and strategies associated with high-performance HVAC equipment.
  3. Apply specific operations and maintenance techniques to maintain good performance.
  4. Determine the difference between initial cost and total cost of ownership for a piece of equipment.
  5. Add the requirement for total cost of ownership analysis to proposals.
  6. Develop specifications for product and equipment vendors that offer energy-efficient products.
  7. Describe how high-performance equipment can help building owners comply with local and state energy efficiency requirements.
  8. Describe typical utility incentives and tax credits that apply to high-performance heating and cooling equipment.
  9. Describe how high-performance equipment can help building owners meet building energy management goals and policies.
  10. Describe industry awards and certifications, such as LEED, that apply to high-performance equipment.
  11. Describe how and where energy is wasted in a typical building.
  12. Explain the theory of energy recovery from air and water source systems.
  13. List the types of air and water source energy recovery systems.
  14. Implement operational practices for energy recovery from air and water source systems.
  15. Describe the design considerations related to air and water source energy recovery systems.
  16. Describe typical utility incentives and tax credits that apply to implementing energy recovery strategies.
  17. Explain why capturing heating and cooling energy before it is vented or wasted is a cost-effective strategy.
  18. Describe how energy recovery techniques can assist building owners in meeting energy management goals.
  19. Demonstrate the cost effectiveness of energy recovery techniques using energy accounting principles.
  20. Describe how energy recovery strategies can help building owners comply with local and state energy efficiency requirements.
  21. Describe industry awards and certifications (e.g., LEED) that apply to energy recovery strategies.
