There is happening a lot to get energy data standardized. For buildings the BEDES building energy data exchange format is developed and applied in tools like BuildingSynch. A visit to UC Berkeley or NREL would be natural within the CITIES consortium (having to find funding).
If your working with IT, interoperability through standardization, this would be the perfect project for you. In Denmark, work is going on at Energynet.dk for the national DataHub.
The project would collect standardization efforts national and international and find standards that could be useful for the building energy data collection and exchange and implement it. Similar work for electricity and other sources could be supervised by colleagues from other departments.
