THERMAL ENERGY STORAGE IN THE ERA OF SUSTAINABILITY
During the 1980s and 1990s, cool thermal energy storage (TES) was a key technology in US utility demand-side management (DSM) programs. Interest in TES declined steeply as incentives disappeared during utility deregulation. Today, the focus of design has shifted from energy cost savings toward sustainability and it is reasonable to ask whether TES has anything to offer in this environment. This presentation will review the essentials of cool thermal energy storage and examine its relevance to sustainable design. Specific issues examined will include the impact of TES on site and source energy consumption, the economic case for TES without the incentives of the DSM era and the role of TES in achieving net zero energy buildings and communities.
Lunch & Presentation 12:00 pm – 1:30 pm – West Auditorium (1.0 PDH)
THE ASHRAE BUILDING ENERGY LABELING PROGRAM
Whether voluntary or mandatory, the rating of the energy use and indoor environmental quality of buildings is a growing trend worldwide. In 2009, ASHRAE introduced its own “Building Energy Quotient” (bEQ) labeling program for new and existing buildings and is now in the process of piloting it in a number of locations around the U.S. It is an ambitious program comprising not only the development of an energy use performance scale, but also tools and procedures for performing ratings and certification of the qualified energy modelers and building assessors needed to implement it. This presentation will provide an overview of the bEQ program, describe its relationship to other building certification programs in the US and elsewhere, identify the potential benefits of certification, and summarize the current state of implementation of the program and plans for the future.

Utah ASHRAE March 2nd Tech Session/Lunch Meeting
Date: Friday, March 2nd, 2012
Location: Intermountain Medical Center/Doty Family Education Center
5121 S. Cottonwood St. (100 West), Murray, UT
Time: Technical Session (Classrooms 3, 4, and 5) – 9:00 am – 11:30 am
Lunch & Presentation (West Auditorium) – 12:00 pm – 1:30 pm
Presenter: Kent W Peterson, Vice President / Chief Engineer of P2S Engineering, Long Beach, CA andASHRAE Distinguished Lecturer
Technical Session 9:00 am – 11:30 am – West Auditorium (2.0 PDH’s)
Chiller plants must minimize the annual energy consumption while providing the necessary cooling to each of the loads in the system. This session will cover innovative techniques for the design and operation of energy-efficient optimized chilled water plants. Mr. Peterson will explain how to determine various operational parameters for optimizing plant efficiency.
Variable-primary flow chilled water systems have received much current attention. It has been suggested that the primary/secondary chilled water system concept has outlived its lifespan and that variable-primary flow is the answer to the problems that have led to its demise. Mr. Peterson will share his experience with both types of systems and when they are appropriate. He will also discuss how to optimize pumping energy in large campus chilled water distribution systems.
Engineers and facilities operators have many decisions to make when designing and operating central chilled water plants today. Many of these decisions require extensive consideration of elements beyond the perimeter of the plant. Some of these questions include:
• How can a higher chilled water delta T be achieved?
• How will the cooling coil performance impact the central plant performance?
• How do you select the proper chillers, cooling towers and pumps?
• What effect does delta T have on chiller performance?
• What plant configuration best fits the requirements?
• What control strategies can be used to optimize plant performance?
• What type of building interface should be used to connect to central systems?
• When is thermal storage viable?
This technical session will discuss ways in which designers and operators can address these technical aspects to operate energy efficient chilled water plants that perform.
Lunch & Presentation 12:00 pm – 1:30 pm – West Auditorium (1.0 PDH)
Optimizing Central Chilled Water Systems
Chiller plants must minimize the annual energy consumption while providing the necessary cooling to each of the loads in the system. This presentation will present innovative techniques for the design and operation of energy-efficient and life-cycle cost optimized chilled water plants.
Variable-primary flow chilled water systems have received much current attention. It has been suggested that the primary/secondary chilled water system concept has outlived its lifespan and that variable-primary flow is the answer to the problems that have led to its demise. Mr. Peterson will share his experience with both types of systems.

What control strategies can be used to optimize plant performance?
How do you select the proper chillers, cooling towers and pumps?
What type of building interface should be used to connect to central systems?
When is thermal storage viable?
Both designers and operators must properly address these technical aspects to operate efficient chilled water plants that perform.
