Energy Recovery

July 18, 2019
1 p.m. – 2 p.m.
Eastern Time

 

This presentation demonstrates the application and benefit of enhanced energy recovery in the design of both new construction and retrofit ab building projects. The new University of Delaware Star Comet Lab Building upholds the institution's long and distinguished history of research in the areas of energy and the environment. Energy efficiency was a primary consideration in the design and selection of mechanical systems.

As a result of energy recovery system analysis, the sustainable and energy efficiency highlights include:

  • 91 percent of the annual heating energy requirement provided by the energy recovery system
  • 40 percent of the annual cooling energy requirement provided by the energy recovery system
  • Over $1 million of costs savings in achieving N+1 heating plant redundancy
  • Reduced heating plant footprint improved space management
  • Improved heating plant COP due to lower hot water supply temperature requirements and greater temperature differentials associated with energy recovery system

The University of Denver's Seeley Mudd Lab Building was originally designed and constructed in 1980. When planning a mechanical systems upgrade, in an effort to improve the building efficiency and mechanical system reliability, the project design team performed an analysis of the potential impact of a high performance energy recovery option. The analysis included an evaluation of required heating and cooling plant capacity as well as the potential impact of planned lighting and boiler efficiency upgrades based on prior lessons learned.

The sustainable and energy efficiency highlights include:

  • One coil design resulting in smaller air handling unit footprint improved space management
  • 98 percent of the annual cooling energy requirement provided by the energy recovery system
  • Improved future condensing boiler efficiency at winter design condition due to an ability to deliver optimal heating water return temperatures
  • Downsizing the original 220 ton water cooled chiller to a new 160 ton magnetic bearing chiller
  • Revolving energy fund investment payback of less than 5 years

Both projects, as a result of energy recovery system considerations early in the design-development process, were able to maximize energy efficiency in a financially responsible and sustainable way.

After viewing this presentation, attendees will:

  1. Understand how can the selection of a high performance energy recovery system result in a lower initial capital costs as compared to a conventional energy recovery system;
  2. Learn why is it important to consider energy recovery options early in the design-development process;
  3. Understand how a high performance energy recovery system can help achieve N+1 redundancy with significantly less boiler capacity; and
  4. Be able to review energy recovery considerations when planning lighting and boiler system upgrades.
