The American-Chinese Coalition Organized for Responsible Development in the 21st Century (ACCORD21) sought leading construction and design technologies for this “green building” project. As a result, two 100-ton Carrier screw chillers (30HXC100), using environmentally sound, non-ozone depleting R-134a refrigerant, will be installed in the new, eight-story, 130,000–sq-ft sustainable energy office building and demonstration center being constructed in downtown Beijing. The chillers will make and store up to 50 tons of ice per night, which in turn will be used to cool the building during the day. Once completed in 2003, the green office building will be fully monitored to track energy consumption, savings, and GHG reductions resulting from its integrated efficiency and renewable technology and design strategies. The facility’s Technology Demonstration Center will exhibit energy efficient technologies and design strategies for the entire building industry.
