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

Building Green, Saving Green: Constructing Sustainable and Energy-Efficient Buildings
Experts in the field of green building, such as members of the U.S. Green Building Council and Kent Peterson, PE, the president of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), appeared before Chairman Edward J. Markey (D-Mass.) and the Select Committee on Energy Independence and Global Warming to discuss how more efficient buildings and better building policies can reduce energy costs and cut global-warming pollution...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 still often prevails...MORE
