Awardees - CalSEED

Gridware was founded with the belief that the passion and agility of start-up innovations will play a decisive role in the modernization of our power grid. As devastating wildfires hit communities and millions of hectares of land more frequently and more violently, a critical step in addressing this challenge and the many other challenges of climate change is the ability to bring together experts, grid operators, regulators and innovators to solve them together. To do this, we need a solution that is dynamic and deployable. A solution that is predictive and precise. A solution that stays ahead of the problem rather than catching up. We are building Gridware to be that solution.

Practical Data Science Methods to Identify and Quantify Non-Routine Events in Building Operations

Location: Pleasanton, CA (possibly partially remote)

Supervisor: Matt Bonasera

InTech is seeking to enhance the analytic capabilities of our Energy360® energy management technology (EMT)to better identify and quantify changes in building equipment and energy use operations due to non-routineevents, anomalies, or planned energy efficiency projects. The goal is to implement a minimally intrusive data collection process that uses building meta-data (size, usage, HVAC system type, etc.), weather data, and theprimary utility meter data, and minimal additional energy monitoring or sensoring, that can be used on individual buildings, i.e., we are not seeking a population-based analysis.

The anticipated role is a combination of data science and an understanding of the physical nature of building operations. The data scientist would access InTech’s and other historical building energy usage databases (US Dept. of Energy, US Energy Information Administration, Energy Star, Utility studies, Electric Power Research Institute studies, etc.) to discover patterns for normal and abnormal energy consumption that can be repeatedly used in analyzing, measuring and forecasting energy use in buildings.


Strong background in creative data analyses, and working with large data sets using a variety of techniques to solve a real-world problem. Must have practical experience in scaling creative solutions for production scale in a software product environment. Experience can be shown with class projects or independent projects. Education in Data Science and related areas would be very helpful.

Other preferred qualifications:

The ideal candidate will also understand the basic physical nature of building operations, e.g. understanding how factors like weather, building usage, and building occupancy influence energy consumption.

At Johnson Controls, we transform the environments where people live, work, learn and play. From optimizing building performance to improving safety and enhancing comfort, we drive the outcomes that matter most. Dedicated to protecting the environment, we deliver our promise in industries such as healthcare, education, data centers, and manufacturing.

Transfer Learning for Advanced Building Controls

Location: Berkeley, CA

Supervisors: Tianzhen Hong, Building Technology and Urban Systems Division

Machine learning (ML) models have demonstrated excellent performance in optimizing building controls for energy efficiency and demand flexibility. However, transfer learning is a challenge in ML based building controls as a very limited number of buildings have adequate and good-quality data for training and validating ML models. Transferring these ML models to other buildings with limited data will require effective algorithms which are structured in a way that bridges two different buildings capturing their common and different characteristics (e.g., energy system type, operation strategies, climates). The intern will help review transfer learning algorithms and choose a few to test for reinforcement learning based building controls.  One intern is needed.

The intern is required to have knowledge of machine learning especially reinforcement learning and understand transfer learning. It is a plus if the intern knows how to use popular ML toolkits for Python coding and testing ML models. The intern will be part of a project team presenting and discussing progress weekly. Depending on the outcomes, there is a potential for the intern to contribute to the writing of a journal article.

However, we still need to better understand how molecular architecture dictates the nanoscale assembly of polymer molecules and ultimately membrane performance. This internship will focus on probing the nanoscale structure of membranes using unique experimental X-ray tools coupled with simulations and other characterization methods to gain new insights into membrane structure-property relationships. The work will involve working closely with research groups at Berkeley Lab and take advantage of Berkeley Lab's world-class facilities, including the Advanced Light Source and the Molecular Foundry.

Takachar is an MIT spinout company with a test site in Berkeley, CA. The company's vision is to expand the amount of biomass (crop and forest residues) economically converted into useful products (we turn trash into cash). Our impacts include income and job creation in rural areas, as well as mitigation of CO2 emission and air pollution associated with conventional open-air biomass residue burning. If successful, this could also potentially reduce the risk of catastrophic wildfires.
