For Immediate Release


Mark MacCracken Named ASHRAE Distinguished Lecturer

Englewood, NJ – Organizations whose members consist of building owners, building managers, architects or engineers involved with cooling commercial buildings, can hear presentations by Mark MacCracken who has recently been named to a two year term as Distinguished Lecturer by the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE).  MacCracken’s topics include Thermal Energy Storage (TES) and LEED, TES Myths and Basic Control Theory for TES Systems, a synopsis of which follows:

Thermal Energy Storage and LEED
Thermal Energy Storage used for Off-Peak Cooling of buildings, has a long history around the world with over 6,000 commercial installations in 35 countries.  By storing cooling at night, in the form of ice or chilled water, and using it during the day to cool the buildings, major reductions in on-peak electric demand and energy costs are realized.  This talk will demonstrate the basic types of TES systems, how they save energy and reduce energy costs and how this relates to the US Green Building Council’s LEED rating system.


TES Myths
Thermal Energy Storage, used for Off-Peak Cooling buildings, has a long history around the world.  The technology’s application in commercial cooling has evolved and improved over the past 2 decades however myths continue to keep it from becoming a staple in energy efficient building design.  The talk covers some of the myths surrounding Ice-based TES.


Basic Control Theory for TES Systems
Proper control of TES systems is the single biggest factor in maximizing the financial benefits the system can provide.  Basic modes of operation are common to all types of TES systems however system layout has direct impacts on how to accomplish the control objective.  Different sizing and operating strategies are analyzed and demonstrated.



MacCracken is the CEO and president of CALMAC Manufacturing Corp., a leading producer of Thermal Energy Storage technology.  He is a Licensed, Professional Engineer in New Jersey and a member of ASHRAE, Chairman of TC 6.9 Thermal Storage and ASHRAE TC 10.2, ARI (Chairman of TES Subcommittee), US Green Building Council (USGBC), and the International District Energy Assoc. (IDEA), and is the holder of 3 U. S. Patents.

He is a 1976 Distinguished Graduate of the University of Rhode Island where he earned a BS degree in Mechanical Engineering and where he was installed as a member of the Pi Tau Sigma Scholastic Honor Society.

ASHRAE, which was founded in 1894, is an international organization of 55,000 persons. Its objective is to advance through research, standards writing, publishing and continuing education the arts and sciences of heating, ventilation, air conditioning and refrigeration to serve the evolving needs of the public.  To arrange for a lecturer visit by MacCracken, contact Rosy Douglas, manager of chapter support, at or call her at 404-636-8400.

CALMAC Manufacturing Corporation, an Energy Star® Partner and USGBC member, is a leading manufacturer of Thermal Energy Storage / Off-Peak Cooling equipment.  The company has over 3,000 ice storage installations worldwide.   For more information on Mark MacCracken or CALMAC, contact CALMAC Manufacturing Corporation, 101 West Sheffield Avenue, Englewood NJ 07631-4880, telephone: 201/569-0420 or visit their web site at
