| Paul von Paumgartten & Thomas Hartman to Present Keynote Addresses at EGB 2007
Johnson Control's Paul von Paumgartten will present the opening keynote address at EGB 2007 Monday, Sept. 17, at 8:15 a.m. in Las Vegas. Von Paumgartten, one of the U.S. Green Building Council's most distinguished members and a renowned green-building-industry leader, will speak about "Achieving and Measuring Sustainability in Green Buildings." His speech will address the evolution of the high-performance green-building industry, which began as an energy-efficiency movement and has evolved into a performance/sustainability movement with a lifecycle approach. Click here for more on Paul von Paumgartten and his address.
The following morning, Thomas Hartman will open Tuesday's sessions with his talk on "Leadership: Your Most Valuable Contribution to Sustainable Projects." According to Hartman, an internationally recognized expert in the field of advanced high-performance building-operation strategies, we have the tools and technology to make green happen. What we lack is leadership in the buildings community. Click here for more information on Thomas Hartman and his talk.
EGB Focuses on the Role of Mechanical Systems in Green Design As the only green-design event dedicated to mechanical systems in non-residential buildings, EGB 2007 will offer practical and useful technical information on green-building design and technology as they apply to mechanical systems in commercial buildings.
This year's event will be held Sept. 17 and 18 at the Mandalay Bay Resort and Casino in Las Vegas and will emphasize the education, hospitality, and government sectors. More than 20 sessions already are scheduled.
This is a must-attend event for all professionals involved in the design, construction, commissioning, operation, and maintenance of commercial buildings. Only EGB can provide you with specific skills and information you need to apply green design to heating, cooling, ventilation, engineered piping, controls, energy management, and other HVAC-related engineering specialties. You just can't get this kind of practical, hands-on experience anywhere else!

FREE HPAC Webcast: Rightsizing Rooftop Equipment
Wednesday, Aug. 22, 2007, at 2 p.m. ET
Like an automobile in stop-and-go traffic, a rooftop-package unit suffers because of excessive cycling. Starts and stops accelerate wear and tear on equipment, which can lead to premature failure. Compared with their "rightsized" 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 an independent compressor, more closely can 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...[MORE]
