Our March guest speaker will be Peter Simmonds. A biography and his topic are as below. Hope to see everyone there!

Senior Associate, Head of the Advanced Technology Group
IBE Consulting Engineers
Sherman Oaks, CA 91423

Peter Simmonds has a Bachelor of Science degree in Mechanical Engineering and another in Research and Development from Reading Technical College, and a Master’s degree from HTS, Den Bosch, The Netherlands and a Ph.D. from T.U. Delft.   He has been a member of ASHRAE since 1989.
Dr. Simmonds is a recognized authority in the field of Radiant heating and cooling systems, as well as Thermal Comfort. The main goals of his research and applications have been to understand the heat transfer and performance of radiant systems for both heating and cooling. His studies related to thermal performance of these systems led to a unique way to enhance in these systems.  Publications of his work led to the development of radiant systems in the USA and are included in the ASHRAE Handbooks.
He has received the Carter Bronze Medal from the Chartered Institution of Building Services Engineers in 1993.

He has authored or co-authored more than 60 technical papers, articles and books He is a member of several ASHRAE Technical Committees and serves on the Handbook committee as well as Standard 55. Peter also teaches Graduate and Post Graduate Architectural students at the University of Southern California and Woodbury University.

High Performance buildings and Occupant Comfort
This lecture illustrates that the Predicted Mean Vote/Percentage Persons Dissatisfied (PMV/PPD) can be used to produce optimal designs for a number of different applications. One application was to evaluate an existing building to provide the owner with information on how to improve occupant comfort and improve building efficiency. 

Previous work by Simmonds have shown that the effects on comfort results when varying clothing levels and metabolic rates of occupants is relatively small compared to changes in the engineered variables such as dry bulb temperatures, humidity, air velocity and mean radiant exchange. This lecture will show the results of the design process for each of the buildings explaining the intricacies of each solution and show that the new ASHRAE standard 55 can be used as an effective design and analysis tool for modern designs.
