Re(de)fining Net Zero Energy: Renewable Emergy Balance in Environmental Building Design Dr. Ravi Srinivasan Assistant Professor Rinker School of Building Construction College of Design, Construction and Planning University of Florida http://www.bcn.ufl.edu/dcp_faculty_staff/srinivasan.shtml Abstract: This talk discusses a new concept (Renewable Emergy Balance) to guide building design toward sustainability. This concept builds on the current building design criteria, Net Zero Energy, by expanding it to the entire building life cycle and considering all inputs, not just energy, on a common basis as emergy. The process is to establish a potential based on the nonrenewable inputs that can be substituted by renewable inputs. This property is called Renewable Substitutability. Higher states of sustainability can be obtained by progressive substitution of nonrenewable with renewable inputs over the buildings life time. US EPA's Atlantic Ecology Division building in Narragansett, RI was used as a case study to guide building design toward sustainability. --------------------------------------------------------------------------------------------------- Seminar series website with schedule and recordings for past seminars: http://www.cfw.ufl.edu/seminar_schedule.shtm<http://www.cfw.ufl.edu/seminar_schedule.shtml>l<http://www.cfw.ufl.edu/seminar_schedule.shtml> -- Sharlynn Sweeney, PhD Center for Environmental Policy and H.T.
