Dr. Joana Abreu leads human-systems dynamics research for Fraunhofer CSE’s Building Energy Systems Group. At Fraunhofer CSE, she works with a team comprising engineers, building scientists and psychologists to apply experimental psychology methods to complex systems-level research in both field and laboratory research projects. She developed an externally-funded interdisciplinary research program that includes such diverse subjects as energy efficiency, social science, data analytics, environmental engineering and geographical information systems.

Joana joined Fraunhofer CSE in 2013. Her work centers on the intersection of home energy management technology, data analytics, occupant behavior, and building science to understand energy-use decisions and behaviors and to evaluate the human factors in demand response, technology adoption and acceptance.

Prior to joining Fraunhofer Joana co-designed and managed the automated demand response project “Roriz On Demand” a residential demand response field experiment involving 450 residential users (38% recruitment rate). She was also an independent expert to GALP, a National utility, in the award winning  the residential feedback interface Smart Galp. In 2009 she co-authored a project NET ZERO Energy School: Reaching the Community, focused on evaluating the impact of information provided at school in residential energy dependent habits.

Joana has worked in industry and government for over 15 years. She holds a Doctoral Degree in Sustainable Energy Systems from the MIT Portugal Program studying habitual behavior and feedback in the residential sector and a Master’s degree in geographical information systems from the University of Leeds, UK.

In her spare time Joana enjoys biking, surfing New England’s baby-waves and hiking with her son and their dog.
