The Use of Renewable Energy in New and Existing Buildings
Energy utilization and the release of harmful emissions are among the global community’s principal concerns, especially relating to significant energy consuming systems, such as buildings. Buildings account for approximately 40% of the worldwide annual energy consumption (WBCSD 2009). Total global energy consumption in 2007 was about 500 quadrillion British thermal units (Btu), meaning the buildings sector consumed about 200 quadrillion Btu. According to the Energy Information Agency, worldwide energy consumption is expected to increase by about 1.4% per year through 2035, implying that buildings will consume about 300 quadrillion Btu by the year 2035 (EIA 2010). Therefore, the global community must urgently consider the transition from fossil-fuel based energy sources in buildings to renewable energy sources. This plenary talk will address such a transition, considering renewable energy sources suitable for new and existing buildings. Some case studies and research findings produced at the Thermal Processing Laboratory (TPL) at McMaster University, Canada considering the use of passive renewable energy systems for new and existing buildings will be presented and discussed.
