HPAC Webinar Series: A New Look at Sprinkler Protection for Storage Spaces
Live Event: July 30th, 2008 at 2:00 pm ET
Like the light bulb, the fire protection sprinkler has been a steady, dependable technology for nearly a century with design innovations over time as applications and design requirements have become more diverse.
Providing sprinkler protection for storage spaces requires adherence to strict code and approval body requirements and robust products that can perform under intense and potentially catastrophic fire conditions, both to human life and to capital assets. In this presentation, learn about advancements in sprinkler performance, flexibility in system design and new technology that addresses today’s growing storage demands.
Please join this special presentation by Dr. HC Kung of Victaulic on the current and future states of storage sprinkler technology. He will discuss the evolution of the Early Suppression Fast Response (ESFR) and Control Mode product classifications and what Victaulic is doing to address the future needs and current trends within the storage fire protection market.
Dr. Kung has nearly 40 years of innovative experience in the design and establishment of sprinkler technology and is a known global authority on sprinkler design.
HPAC Webinar Series: Aquatic Center Success - Form Follows the Function of Water, Air and Motion
Live Event: Wednesday May 14th, 2008 at 2:00 pm ET
We’ve all heard the famous adage, “form follows function.” It’s a basic tenet of designing a successful building or facility.
Such is the case for aquatic centers too. Environmental conditions within these types of facilities are unlike those found in most large buildings and structures. Major differences that affect the indoor environment include the vast amount of exposed, treated water in pools, the airflow and humidity levels within facilities and the rigorous activities that are conducted within them. Understanding how these factors affect your facility and knowing how to design for their impact directly affects the longevity and long-term success of your natatorium.
Join a special webcast presented by John McIlhargy, Director of the Facility Development Department for USA Swimming, along with Harry Milliken III, Northeast Regional Sales Manager of Desert Aire, as they discuss these important issues and provide practical solutions to help you develop and maintain a successful aquatic center. To learn more about our presenters click here. This webinar will cover:
- chloramines and their negative impact on pool structures
- proper chemical composition of pool water
- the effects and treatment of air stratification above pools
- meeting ASHRAE Standard 62 for swimmers and spectators
- appropriate facility pressurization, humidity levels and air distribution
Grease Ducts: New Generation
Conventional grease ducts are field-welded, and require 18˛ clearance to combustibles. In most cases, these ducts are field-wrapped with insulation to reduce clearance to combustibles and provide fire resistance rating. The new generation of factory-built grease ducts offers a better alternative to conventional and field-wrapped grease ducts. This webinar examines these new modular grease duct systems which offer zero clearance to combustibles and fire resistance ratings, discusses the certification testing they undergo, covers the standards and codes with which they comply, and describes their features and benefits.
Participants will be educated about:
- The new modular, non field-welded, insulated grease duct and its features & benefits
- The fire tests this grease duct undergoes for listing.
- The standards and codes this grease duct complies with.
Energy Recovery Ventilation: An Overview of a Critical Technology for High Performance HVAC System Design

The subject of energy recovery ventilation is filled with myths and disinformation. To be viable in an energy starved future, HVAC systems must efficiently process ventilation and make productive use of low-grade energy resources ignored or discarded by classical HVAC strategies. That means air-to-air energy recovery technologies will be critical and central elements of high performance HVAC systems that achieve cost-effective “net-zero” building design. As such, they will revolutionize HVAC system design.
Air-to-air energy recovery technologies take numerous forms and each offers unique capabilities that are superior for specific applications. Each also presents unique limitations, and there are challenges to their effective application. The HVAC industry is only beginning to learn how to use these important technologies.
Boiler Efficiency Ratings: What You Don't Know Will Cost You
Wednesday, February 27, 2008

Sponsor: Aerco - http://www.aerco.com
Published efficiency ratings for hydronic boilers don’t provide an accurate assessment of equipment performance in most real world applications. Nor do the published ratings enable facility managers to effectively compare the relative performance of different boilers under the same operating conditions. In order to better predict performance, it is necessary to examine ANSI Z21.13, the test standard set forth by the American National Standards Institute to support energy efficiency claims made by equipment manufacturers.
This presentation will help attendees understand the impact of ANSI test parameters and test conditions on the published efficiency ratings of hydronic boiler equipment. It will compare and contrast the test environment to conventional heating system designs typically found in most commercial applications. To help attendees achieve the highest efficiencies and energy cost savings possible in an existing or new building, the presentation will identify several design and operational strategies which help to optimize hydronic system performance.
New Trends In Laboratory Exhaust

Laboratory exhaust systems have been installed for ventilating lab facilities for decades. These systems range anywhere from field assembled components to factory fabricated systems.
In either case, there has been no independent third party verification of entrained dilution performance and total discharge air flow from these systems.
This webinar will discuss these issues and the new AMCA (Air Movement and Control Association) test standard and certification of performance for high plume dilution blowers used in laboratory exhaust.
Rightsizing Rooftop Equipment

Like an automobile in stop-and-go traffic, a rooftop package unit suffers as a result of excessive cycling. Starts and stops accelerate wear and tear on equipment, which can lead to premature failure. Compared with their "right sized" counterparts, oversized systems cost more, do not dehumidify as well, use more fan power, and can have more duct leakage because of higher duct pressure. Oversized air conditioners greatly aggravate peak kilowatt demand on hot days. Rooftop units in smaller sizes have one compressor and operate in an "on" or "off" mode. Equipment usually is selected to provide the needed capacity on the hottest afternoon of the hottest summer. Because those conditions occur infrequently, a single compressor is more or less oversized for all conditions less severe than maximum design. This excess capacity causes short-cycling and higher operating costs. Dual refrigerant circuits, each with its independent compressor, can more closely provide the right amount of cooling needed. Unless conditions require the second circuit, only one compressor is used—consuming less energy than a single-compressor air conditioner would use.
Pumping and Piping Systems for Tall Buildings

Sponsor HPAC
In tall buildings, heating-, chilled-, or condenser-water distribution is crucial to building comfort, but presents unique challenges. Among the issues that need to be addressed are the static-pressure gradient that exists in tall buildings and the size, complexity, and associated mechanical-design issues of such large distribution systems. This webinar will address each of these issues and discuss approaches that significantly reduce energy use.
