Web-Based Visualization and Prediction of Urban Energy Use from Building Benchmarking Data

Published in Bloomberg Data for Good Exchange 2015, 2015

Details two projects to increase both the availability and comprehensiveness of building energy data through interactive visualization and extrapolation with predictive models. Received ‘Best Paper’ award at the Bloomberg Data for Good Exchange 2015. Read more

How Much Water Does Turf Removal Save? Applying Bayesian Structural Time-Series to California Residential Water Demand

Published in KDD Workshop on Data Science for Food, Energy and Water, 2016

Monthly water savings from turf removal are estimated at the household level as the difference between actual usage and a synthetic control and then aggregated using a mixed-effects regression model to investigate the determinants of water savings. Read more

A data-driven predictive model of city-scale energy use in buildings

Published in Applied Energy, 2017

We use statistical models to predict the energy use of 1.1 million buildings in New York City using the physical, spatial, and energy use attributes of a subset derived from 23,000 buildings required to report energy use data each year. Linear regression (OLS), random forest, and support vector regression (SVM) algorithms are fit to the city’s energy benchmarking data and then used to predict electricity and natural gas use for every property in the city. Model accuracy is assessed and validated at the building level and zip code level. Read more

talks

MindSoccer

Published:

Presented my capstone project for my B.S. in Computer Science: “MindSoccer” which was a project to navigate robotic vehicles using a brain-computer interface. This was my very first conference presentation so I was understandably nervous, but the crowd enjoyed our presentation and the accompanying demonstration with the vehicles and headsets. Read more

Web-Based Visualization and Prediction of Urban Energy Use from Building Benchmarking Data

Published:

Co-presented with my advisor to talk about our conference paper. Since we won the ‘Best Paper’ award, we also got to present the next day at Strata Hadoop World. This was quite fun, and we were set up in the middle of the Expo hall with a large screen. At the last second my advisor got stuck in traffic and couldn’t make it so I had to completely ‘wing’ his portion of the talk. I pulled it off but it was definitely a bit more exciting than I had planned! Read more

How Much Water Does Turf Removal Save?

Published:

Presented on behalf of my coauthors to talk about our conference paper on estimating the water savings attributable to turf removal programs. The workshop was an eclectic mix of topics, mainly from agriculture and water resources. The ag presence was heavy with a large showing from Iowa State and Purdue, likely because these were the institutions of the keynote speakers. Read more
