Technologies for Positive Energy Buildings and Communities

Commercial and residential buildings represent about 40% of the total energy consumed worldwide. Therefore, buildings present a tremendous opportunity for energy conservation. New standards, incentives and initiatives are being created to support energy goals towards Net-Zero or even positive energy buildings and districts.

Methodologies, processes and technologies exist today that follow these new standards and the design and operation of new and existing buildings. These technologies can help reducing energy demand, supplying energy locally to buildings, shifting peak energy consumption, and improving the decision-making process throughout the building value chain (design, construction, commissioning, operation and maintenance, and decommissioning). In spite of the multiple efforts and demonstrations of these new processes and technologies, many factors are slowing the rate of technology adoption, including the current buildings value chain, the lack of the required supporting infrastructures, the shift in skills and knowledge required to implement and use these technologies, and the required initial investments, among others.

Dr. Oggianu will present state-of-the art technologies applicable to the building lifecycle, including processes and tools for building modeling, building auditing, retrofit analysis, multi-level controls and
diagnostics; and supply and storage technologies. She will also present case-studies illustrating the cost and benefits of each of these technologies, and their potential contribution towards Net-Zero or Net-Positive Communities.

Stella Oggianu, Project Leader for Energy Systems, United Technologies Research Center, CT

Dr. Oggianu holds a Ph.D. and an M.S. from the Massachusetts Institute of Technology (M.I.T.).
