The American Society of Heating, Refrigerating and Air-Conditioning Engineers has announced the lineup for its April 14 closed-circuit broadcast on homeland security. The broadcast is hosted by the ASHRAE Presidential Ad Hoc Committee on Homeland Security and is funded through a grant from the Alfred P. Sloan Foundation in New York.

Presenters and topics will include:

· A summary of ASHRAE's "Risk Management Guidance for Health, Safety and Environmental Security Under Extraordinary Incidents" report, and building codes and standards. Lawrence Spielvogel, P.E., a consulting engineer in King of Prussia, Pa., and chairman of the presidential ad hoc committee, will discuss the report and the results of a recent workshop, "Assessing the Need for Building Codes and Standards to Enhance Homeland Security," organized by ASHRAE under its membership in The Infrastructure Security Partnership.

· "HVAC and Refrigeration Systems," hosted by William Coad, P.E., of Coad Engineering Consulting in St. Louis, Mo., will discuss security issues related to design and operation of HVAC and refrigeration systems in both existing and new buildings.

· "Ventilation and Pressurization," hosted by Andy Persily, Ph.D., from the National Institute of Standards and Technology in Gaithersburg, Md. Persily will discuss design and operation of HVAC systems to provide ventilation and pressurization necessary for protection of occupants.

· "Filtration and Air Cleaning," presented by H.E. Burroughs of Building Wellness Consultancy Inc. in Alpharetta, Ga. Burroughs will talk about design, operation and maintenance of filtration systems and application in refuge areas.

· "Microclimate," hosted by Ralph Goldman, Ph.D., of Comfort Technology in Framingham, Mass., will discuss protective systems and equipment and their effectiveness.

"With the United States federal government recently declaring that a significant risk of terrorist attacks exists, the need for information to keep building occupants and buildings safe is more important than ever," said Ron Vallort, P.E., who will host the broadcast. "This information is vital to the people responsible for design, construction and operation of buildings as well as those responsible for assessing potential threats and preparing for the risks of attack on facilities."

The broadcast will be divided into two 60-minute segments. The first will focus on homeland security issues relating to buildings and HVACR systems, followed by 15 minutes for questions and answers. The second will focus on protecting buildings from chemical, biological, radiological and associated threats.
