HPAC Engineering Webinar Series: Grease Ducts: New Generation

May 28, 2008 @ 2 p.m. ET
Sponsor Selkirk, http://www.selkirkcorp.com

Conventional grease ducts are field-welded and require 18-in. 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 a new modular, non-field-welded, insulated grease duct and its features and benefits; the fire tests this grease duct undergoes for listing; and the standards and codes with which this grease duct complies...MORE

Open for Public Comment: Improvements to the LEED Green Building Rating System
The U.S. Green Building Council (USGBC) opened a public-comment period on Leadership in Energy and Environmental Design (LEED) 2009, the next evolution of the LEED green-building certification system. LEED 2009 represents a reorganization of the existing LEED rating system for commercial buildings, combined with technical advancements focused on improving energy efficiency and reducing carbon emissions. Detailed information about specific proposed technical changes to the rating system can be found on the USGBC's Website...MORE

Reverberant Room Method for Sound Testing of Fans
Air Movement and Control Association (AMCA) International announced that the Board of Standards Review of the American National Standards Institute (ANSI) approved ANSI/AMCA Standard 300-08, Reverberant Room Method for Sound Testing of Fans, which establishes a method of determining the octave-band sound-power levels of a fan. The method is reproducible when all requirements are met...MORE


Commissioning and Green Design -- A Natural Combination
The majority of new buildings are not built with energy efficiency in mind, and most of the 5 million existing commercial buildings in the United States have never undergone any type of commissioning or quality-assurance process. As a result, they use more energy, cost more to operate, and perform well below their potential. Conversely, buildings that have been properly commissioned perform better and are more energy-efficient. Yet the idea that commissioning is an unnecessary additional cost often prevails...MORE
