Lakefront Library Green Construction Institute: Advanced Learning For A Sustainable Future Hill Mechanical Group, part of the team for this project, is a member of the Mechanical Contractors Association (MCA) of Chicago and employs workers from United Association Pipe Fitters Local Union 597, who receive green training from MCA Chicago’s Green Construction Institute. MCA Chicago established the Green Construction Institute to further the cause of sustainable practices in the construction industry. In addition to Local 597 apprentices and journeymen, the Institute also offers educational opportunities to the association’s member contractors, as well as engineers, city officials, and building owners, among others. “Education is a top initiative of the association,” said Stephen Lamb, executive vice president of MCA Chicago. “For three years, the association has been instructing our member contractors on sustainable technology. This year, we decided it was time to formalize our efforts by founding the Green Construction Institute.” “Any business in the construction industry that ignores sustainable technology runs the risk of being left behind — and losing market share,” stated Dan Bulley, senior vice president of MCA Chicago, executive director of the Green Construction Institute, and a LEED® Accredited Professional (AP). The Green Construction Institute’s educational offerings include the following: • Introductory course in green building for contractors • Apprentice and craft training • Technical, equipment and design: Training on green building methods and materials • Legal and insurance advice • LEED AP training • Marketing: How to promote green building to clients • CEO training: How business leaders can position their companies • Owner training: Online seminars for owners on LEED Existing Building (EB) and New Construction (NC) • Visioning: How green building will intersect in the future with build-B, building information modeling (BIM), and other industry developments • Green building publications • LEED consulting services • Contractor assistance to find financing options on energy payback projects • Contractor and/or owner assistance to find grants for green projects This September, MCA Chicago and the Green Construction Institute moved from a suite in downtown Chicago to their new headquarters in a green building in Burr Ridge, IL. The building was built and equipped with low-emitting materials, which contribute to better IAQ by releasing minimal toxins over time. “Not only do attendees of the Green Construction Institute learn the latest in sustainable technology,” Bulley said, “but they also enjoy the comfort of a healthier indoor environment as they learn.” To find out more about MCA Chicago, visit www.mca.org. has radiant cooling gained increasing acceptance. The following are some of the advantages of radiant heating and cooling. Comfort/with more energy temperate setpoints. It has been shown that people are comfortable at lower temperatures in heating and at higher temperatures while in cooling when exposed to radiant ceilings or floors. This is due to the radiant energy exchange between the occupant and surrounding heated/chilled surfaces. For example, depending on the temperature of the ceiling, 68°F may feel like 70° in heating, and 77° may feel like 75° in cooling. This operative temperature is a weighted average of air temperature and average surrounding surface temperatures. The radiant energy exchange is governed by the Stefan-Boltmann equation. Using an accepted value of 0.87 for the radiation exchange factor, this equation becomes (using equation 5 from the 2008 ASHRAE Handbook – Systems and Equipment, page 6.2): Qr = 0.15 x 10^-8 [(tp)^4 – (AUST)^4] Where No Problem… Input 217A at www.esmagazine.com/instantproductinfo w w w. esmag a zin e. c o m 29 http://www.mca.org http://www.esmagazine.com/instantproductinfo http://www.esmagazine.com
