Mr. Calm is an engineering consultant specializing in heating, air-conditioning, and refrigerating systems.  His services include performance, environmental, and safety analyses as well as feasibility studies, assessments, research, and strategic planning.  His clients have included manufacturers, engineering and architectural firms, building owners, research organizations, utilities, trade associations, and governmental agencies in the United States, elsewhere in the Americas, Africa, Asia, Europe, and the Middle East.

Mr. Calm is a Fellow of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and a member of both Sigma Xi (an honorary society when elected and now an international society for research) and Tau Beta Pi (honorary society for engineering).  He has served on the United Nations Environment Programme (UNEP) committee assessing technical options for refrigeration, air conditioning, and heat pumps (RTOC) since 1989.  He was the lead author for refrigerants from 1995 to 2014 and also for heat transfer fluids from 2002 to 2006; he was a co-author of one or more additional chapters for each of the prior and current assessments.

Within ASHRAE, Mr. Calm serves as a consultant to and formerly served as a member of the standing committee responsible for the Safety Standard for Refrigeration (ANSI/ASHRAE Standard 15) incorporated into most building codes.  He has served in the past as a member and vice chairman of the committee responsible for the standard on Designation and Safety Classification of Refrigerants (ANSI/ASHRAE Standard 34) and as a member and past chairman of both the technical committees on Global Climate Change and Applied Heat Pump and Heat Recovery Systems.  Mr. Calm also served as an appointed consultant and before that as vice chairman of the committee responsible for the Energy Standard for Buildings Except Low-Rise Residential Buildings (ANSI/ASHRAE/IESNA Standard 90.1), widely adopted in federal and state laws and regulations in many construction codes.  He formerly served as Chairman of the Research and Technical Committee, and was a member of the Technology Council, Government Affairs Committee, Program Committee, Research Promotion Committee, and Research Advisory Panel.

Mr. Calm represented ASHRAE in international meetings for revision of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1992.  He represented the Air-Conditioning and Refrigeration Institute (ARI, now the Air-Conditioning, Heating, and Refrigeration Institute, AHRI) and the international air-conditioning and refrigeration industry for the UNEP Consultative Session with Industry in 1990.  Mr. Calm was the developer and administrator of the ARTI Refrigerant Database, licensed in 32 countries, and is or was the principal investigator for research projects addressing the environmental impacts, materials compatibility, and safety of refrigerants.  Mr. Calm was heavily involved in development of the refrigeration provisions for both the International Mechanical Code and the International Fire Code.  Mr. Calm has been active in revisions to the major model mechanical and fire codes in the USA as well as several state and local building, fire, and mechanical codes.  He has represented ASHRAE on refrigerant and refrigeration issues for the model codes and served on its Code Interaction Subcommittee.  He also has represented ARI, several manufacturers, and building owners in code development, adoption, and implementation issues including acceptance of alternative refrigerants.

He formerly served as Vice President of Research and Technology in ARI, a trade association representing equipment and component manufacturers.  Mr. Calm also was Vice President of the Air-Conditioning and Refrigeration Technology Institute (ARTI), a not-for-profit corporation formed for research and related activities in the public interest.  He served as Technical Manager in the International Energy Agency Heat Pump Center in Germany on an extended consulting basis.  In prior employment in the USA, Mr. Calm managed heat pump development projects for the Electric Power Research Institute and led research programs in heat pump, thermal storage, and cogeneration systems for Argonne National Laboratory.  He also worked, on sabbatical, at the Institut CERAC in Switzerland and served as a mechanical engineer in the U.S. Air Force, with assignments in systems design and operation in both Italy and the United States.  Mr. Calm has served as a member of the Research Coordination Council of the Gas Research Institute and on a federal task force for program planning at inception of the U.S. Department of Energy.

Mr. Calm has designed mechanical systems for construction or renovation of more than 250 buildings, overseen construction and operation of critical facilities, and authored or co-authored more than 150 technical publications, some translated and republished in multiple languages.  He has presented more than 200 seminars on refrigerants and lectured on air conditioning, heat pump, and refrigeration systems in more than 30 countries.  He served as a selected speaker in ASHRAE's Distinguished Lecturers Program for six years.  Mr. Calm holds bachelor (cum laude) and master of science degrees from Tufts University and has completed several graduate-level management courses elsewhere.  He is a registered professional engineer in Virginia, USA, and also registered or eligible for reinstatement or comity registration, based on national board examinations, in most states and some additional countries.  He is a recipient of both the Exceptional and Distinguished Service Awards from ASHRAE, Richard C. Schulze Distinguished Service Award from ARI, the DeFlorez Award for Human Factors Engineering, and the Alumni Award for Leadership from Tufts University.
