"LCB's plans include deep energy efficiency retrofits of existing buildings to make urban landscapes more sustainable and livable, said Bruce Ray, JM's leader of government affairs. "And that fits quite well both with JM's continued focus on innovative energy efficiency solutions as well as our sustainability policy. By the year 2050, 80 % of the world's population will live in cities. In addition, the Urban Land Institute predicts that 80 % of current building stock will still be in use in the year 2050. As America and the world work to build a new, sustainable foundation for the 21st century, new models are needed for what our urban spaces and places can become. Starting with a block and a half of Denver's historic Lower Downtown district, LCB will aggregate 16 buildings representing 750,000 sq. ft. of existing mixed use, small- to medium-sized commercial buildings to build a business case proving that together these building owners can address deep resource efficiency with an economic model that no single owner could approach on its own. "We are almost two years into our work on our pilot project in Lower Downtown Denver, said Llewellyn Wells, President and Founder of Living City Block. "Additionally, we are in the initial phases of launching an LCB in Washington, DC in the 14th & U district as well as in Brooklyn in the Gowanus Canal area. Living City Block has partnered with a vast array of government, utility, academic and non-governmental agencies to address energy efficiency and renewable energy, water, solid waste and other materials flow, mobility, and placemaking. It has received a US Dept. of Energy Technical Assistance Award from the Commercial Buildings Partnership Program administered by the National Renewable Energy Lab, and has additional corporate partnership/sponsorships with AT&T Colorado, MoyeWhite, LLC and Brownstein Hyatt, Farber & Schreck, LLC, and United Technologies Corporation and their affiliate Architectural Energy Corporation.
