Applying Energy Recovery Strategies to Large HVAC Systems With High-Percentage Outside Air

A Case Study at Johns Hopkins School of Medicine: Renovating a central HVAC plant to increase energy performance can be an expensive, and sometimes risky proposition. This case study examines a successful project upgrading the forced-air system in an older high-rise: retrofitting energy recovery (enthalpy wheels) and changing from Constant to Variable Air Volume. Covering goal-setting, the design effort and evaluation of results, utility rebates, construction process, system optimization, and resulting energy savings, we will focus on general principles, specific project strategies, key systems, obstacles overcome, and the various efforts required to minimize risk and maximize project outcome.

Learning Objectives:
1. Understand the key principles and considerations for retrofitting energy recovery into an existing building air system
2. Understand the key principles and considerations for upgrading building air distribution operations
3. Identify the important milestones and phases of a successful central plant energy upgrade
4. Evaluate existing building central plant conditions to establish realistic goals for a successful energy upgrade project
