Seminar 6
Monday, January 29, 1:00 - 2:30 PM, in the Convention Center

Sustainable Ventilation Systems for Commercial and Institutional Buildings
Track: Systems and Equipment
Sponsor: TC 5.5 Air-to-Air Energy Recovery
Chair: Gregory M. Dobbs, Ph.D., Member, United Technologies Corp., East Hartford, CT

Devices for recovering the energy used for conditioning ventilation air are available using several distinctly different technologies and
are a key part of sustainable design for green buildings. Standards such as ASHRAE 90.1 are increasingly requiring such devices in the
minimum configuration. This seminar will review the choices and some case studies of applying ventilation energy recovery to specific
building sectors and the challenges for specific situations.

Air to Air Energy Recovery Wheels and Plates: What Are They and How Do They Work?
Sponsor: TC 05.05 Air-to-Air Energy Recovery
Chair: Carol E. Marriott, Member, P. Eng, McQuay International, Minneapolis, MN

Air to air energy recovery can take many forms. This seminar discusses some of the forms available today; how they work, when to apply them, and certified ratings per ASHRAE 84 and ARI 1060. Economic impact and energy analysis are addressed.

Certified Ratings for Energy Recovery Ventilation: What You Need to Know!
Sponsor: TC 05.05 Air-to-Air Energy Recovery
Chair: Maury B. Wawryk, Member, Venmar CES Inc., Saskatoon, SK, Canada
APC Liaison: Arthur P. Garbarino, Air Service Inc., West Palm Beach, FL

The need for energy recovery ventilation equipment to resolve inherent conflicts between outdoor air ventilation requirements and energy conservation efforts has never been greater. The market and application of these technologies is growing and engineers are being called upon to understand and specify appropriate devices in their designs. HVI’s residential program began in 1985. In January of 2001, the ARI Air-to-Air Energy Recovery Ventilation Equipment Certified Ratings Program and its directory were launched. The experience and the information available are highlighted and outlined for engineers wishing to take advantage of the latest and best knowledge of the industry.

1. Lessons Learned

Seminar 15
Sunday, January 13, 1-3 PM

Casino Ventilation - Keeping Gamblers Comfortable
Sponsor: TC 05.05 Air-to-Air Energy Recovery
Chair: David F. Shipley, P.E., Member, Marbek Resource Consultants, Ottawa, ON, Canada
APC Liaison: Daniel J. Dettmers, University of Wisconsin, Madison, WI

Hospitality venues, specifically large casinos, are unique among commercial establishments in North America today with respect to indoor air quality, partly because smoking is generally permitted in most such venues. Casinos are service-oriented establishments where the comfort of smokers and nonsmokers is essential to financial success. This seminar presents specific case studies of large casino projects in two challenging climates. Innovative design approaches to meeting stringent owner requirements are presented, along with the results of performance monitoring. These successful, real world examples point the way forward for design of buildings that meet high IAQ standards.

1. Large Casino Case Study: Part I - An HVAC Design Approach for Improved Indoor Air Quality for Las Vegas Casinos
Donald G. Koch, P.E., Member, JBA Consulting Engineers, Las Vegas, NV

2. Large Casino Case Study : Part 2 - IAQ Performance Monitoring
Elia M. Sterling, Member, Theodor Sterling Associates Ltd., Vancouver, BC, Canada

3. Passive and Integrated HVAC Systems for Casino IAQ: Part 1 - Passive Approaches to IAQ
Robert Finnegan, P.E., Member, Finnegan Erickson Associates, Las Vegas, NV

4. Passive and Integrated HVAC Systems for Casino IAQ: Part 2 - IAQ Using Integrated Energy Recovery
Boyd Erickson, Member, CIPE, Finnegan Erickson Associates, Las Vegas, NV
