Simona D’Oca is an Italian architect and PhD Candidate at the Energy Department Polytechnic of Turin. She is currently a visiting scholar at Lawrence Berkeley National Lab, collaborating within the Energy Technologies Area in the Building Technology and Urban Systems Department. Simona has a background in the sphere of sustainable architecture and she strongly believes in the power of the human factor on the energy saving potential of smart and sustainable building and communities. In this context, she raised pivotal attention in her researches towards the understanding of the leverage of energy related occupant behavior on building energy performance. She developed expertise in data mining and statistical analysis, building energy simulations, occupancy models, meter-based feedback behavioral programs and familiarity with social, psychological, economic aspects of consumer energy behaviour. Her researches aim to uncover best practices to support energy modelers and decision makers on how to incorporate patterns of human actions and motivations into behavioral models for bridging the gap between predicted and actual energy performance in buildings.
