SEMINAR: From the Material to the Inter-building Scale: Investigating New Perspectives for Energy Efficient and Comfortable Cities
Anna Laura Pisello
Assistant Professor, University of Perugia
Anna Laura Pisello (PhD in Energy Engineering) is Assistant Professor of Applied Physics at University of Perugia, Italy, formerly visiting scholar at Columbia University, Virginia Tech and CUNY. She takes part to several research initiatives through national and international projects aimed at energy saving in buildings and sustainability of urban areas. She is author of more than 70 international indexed journal papers and editor of five international journals in this field. She won five academic research awards and four European grants in the last 2 years for developing and analyzing new solutions for energy saving, indoor-outdoor microclimate optimization and urban climate change mitigation. She coordinates an active research group at CIRIAF under the framework of the Environmental Applied Physics Laboratory she coordinates at University of Perugia, Italy.
Studying the energy behavior of buildings has become a crucial issue for both building designers and researchers, considering the large amount of energy consumed by the built environment, i.e. about the 36% of total global final energy, and the concomitant potential for energy saving. A United Nations’ study has also predicted that by 2050, a significant shift in population by about 40% from rural areas to urban areas will occur. Coupled with this migration, the morphology of urban areas has been expected to change and new assessment methods are needed to investigate tighter spatial interrelationships among buildings. This trend is already evident in dense urban and quasi-urban areas of the world’s largest cities. Our understanding of buildings needs to evolve to accommodate people and buildings into closer proximity, trying to preserve and even improve population wellbeing. Current modeling and optimization approaches that treat buildings as stand-alone entities do not accurately represent the realistic building thermal-energy performance because they often do not consider:
(i) the physical proximity of other buildings,
(ii) the local specific climate conditions such as urban heat island phenomenon or other temporary microclimate peculiarities,
(iii) the social relationships among building occupants and the role of their awareness about the energy issue,
and the energy implications that these three aspects may produce. This talk will concern the recent research development carried out by Dr. Pisello and her colleagues at University of Perugia-Italy, also in cooperation with other European and extra-EU universities, about new materials and methods to study (i) how to save energy in buildings located in urban context, and (ii) how these urban boundaries can affect human wellbeing of indoor-outdoor environment. Starting from some considerations about new methodological approaches, the talk will deal with new materials, models and case studies investigated by means of numerical, analytical and experimental procedures.
