Some 4,000 renewable energy and green building experts will bring their cutting edge thinking to Boston on March 9-11 for the BuildingEnergy10 Conference and Tradeshow at the Seaport World Trade Center Boston. BuildingEnergy10 (BE10) is the annual event organized by the Northeast Sustainable Energy Association (NESEA). The conference includes 63 sessions and 25 full-day and half-day workshops. The tradeshow floor will feature some 160 exhibitors and the latest technologies, products and services. The theme of this year's BE10 is "Reduce, Retrofit, and Renew." Betsy Pettit FAIA of Building Science Corp., the conference chair for BE10, says the theme is particularly timely as more of us look for ways - big and small - to reduce our carbon footprint. "We at NESEA have been talking and thinking about renewable energy and green design for many, many years, long before it was the topic of the day. We're thrilled that sustainability has finally broken through the public consciousness," Pettit said. NESEA welcomes Dr. Samuel Baldwin as the keynote speaker to BE10 March 10. He is a physicist currently serving as the chief technology officer and a member of the board of directors for the Office of Energy Efficiency and Renewable Energy at the U.S. Department of Energy. "NESEA is the only conference that requires its building case studies to adhere to strict guidelines that include a full year of energy data, reaffirming our commitment to present the best building and energy practices at this conference," Jennifer Marrapese JD MA, interim executive director of NESEA. "We want conference attendees to leave BE10 able to replicate the strategies they learned about during the show. As an organization, we know it is our responsibility to nurture next-generation thinking and spread the wealth. To think and talk about what's worked and what hasn't worked, so we can continue to innovate." *
