Greenbuild Products Cut a Broad Swath
The U.S. Green Building Council’s (USGBC’s) Greenbuild International Conference & Expo is called “the world’s largest conference dedicated to green building.” This year’s theme focused on “What’s Next” for green building. LEED was everywhere.
An estimated 25,000 attendees came together for the educational sessions, renowned speakers, building tours, networking events, and a considerable expo, where they could visit with 1,000-plus exhibitors.
Greenbuild: the Expo
The expo itself was spread evenly across the North and South exhibition halls, with 100-plus educational sessions held in nearby meeting rooms. Exhibitors’ products spanned a broad green spectrum, from special composite building materials and cement, to flooring materials (raised and regular), ceiling tiles, HVAC systems, electronics, wall systems, landscaping, water conservation, and more.
The show’s visitors ranged from homeowners to community planners and builders. The NEWS’ interest was among those exhibitors who would be of the most interest to our readers. However, all of the technologies could affect our systems, if those technologies were to result in lower heating-cooling loads.
“It is encouraging to see the desire for energy efficient technology growing,” said Tony Landers, director of marketing — commercial products at ClimateMaster (www.climatemaster.com).
“Typically, energy efficiency must be regulated for it to be embraced by the construction industry, but now we are seeing an increase in its adoption because it is the right thing to do. Greenbuild highlights this growth and continues to gain momentum each year.”
A/C and Renewables
Carlo Gavazzi Automation Components (www.gavazzionline.com), which specializes in the design, manufacture, and marketing of electronic components, was one of several who promoted solar energy solutions.
