BUDS

BUDS Lab is a scientific research group that leverages data sources from the built and urban environments to improve the energy efficiency and conservation, comfort, safety and satisfaction of humans.

Check us out on Twitter, GitHub, and ResearchGate! Also, take a peek at our sibling labs in NUS with whom we collaborate closely - the Urban Analytics Lab (UAL) and the Integrated Data, Energy Analysis + Simulation (IDEAS) Lab.

BUDS Lab is in the Dept. of Building in the School of Design and Environment at the National University of Singapore (NUS). NUS is the #1 ranked university in Asia and is in the top 25 globally.

Projects

Project Cozie Apple Cozie Apple Watch (ResearchGate) – The latest version of the Cozie clockface application for the Apple Watch platform. This open-source project is led by Dr. Federico Tartarini and is a collaboration with Prof. Stefano Schiavon’s team at the SinBerBEST 2 Lab in Singapore.

IoB The Internet-of-Buildings (IoB) Project – The IoB project focuses on the technology and data convergence of the various researchers in the NUS Dept. of Building. This project is a collaboration with Prof. Daniel Wong and it ties together several projects from within the department.

EDx Data Science for Construction, Architecture and Engineering Online EDx Course – The BUDS Lab hosts the first online data science course focused specifically on data analytics from the various phases of the building life cycle - design, construction, and operations. This is an introductory course that adds Python, the Pandas Data Analytics library and various visualization and machine learning techniques to the toolbox of architects, engineers, operations, and other industry professionals. Over 15,000 participants have taken this course since April 2020.

BDG2 The Building Data Genome Project 2 (BDG2) (ResearchGate) – The BDG2 Project is an open data set made up of 3,053 energy meters from 1,636 buildings. The data set is two full years (2016 and 2017) of hourly frequency measurements from electricity, heating and cooling water, steam, and irrigation meters. A subset of the data was used in the Great Energy Predictor III (GEPIII) competition hosted by the ASHRAE organization in late 2019.

ASHRAE Kaggle The ASHRAE Great Energy Predictor III (GEPIII) Competition on Kaggle (ResearchGate) – The BUDS Lab was the leading technical organizer of the biggest building energy-related machine learning competition ever held with over 3,614 teams who submitted 39,402 predictions. The competition included data from 2,380 energy meters collected from 1,448 buildings in 16 sites and had US$25,000 in prize money for the top five winners. The competition ran from Oct.-Dec. 2019 and was sponsored by ASHRAE and hosted on the Kaggle platform. This competition is a resurrection of prediction challenges hosted by ASHRAE in the mid-1990’s

SpaceMatch SpaceMatch – SpaceMatch is the Uber® of flexible workspaces – an AI-enhanced spatial recommendation engine that matches building occupants to suitable workspaces based on comfort preferences. A live demonstration was implemented in the SDE4 building at NUS and is the focus of a team within the NUS GRIP Program in early 2021.

Project Cozie Fitbit Project Cozie Fitbit (ResearchGate) – A Fitbit-based clockface application that collects momentary assessments of thermal, aural, lighting, and other subjective comfort parameters. This open-source platform is being developed for researchers anywhere in the world to use a methodological component.

Crowdsourcing Comfort: The Learning Trail Crowdsourcing Comfort: The Learning Trail – An NUS Project in collaboration with the Dean’s Office at the NUS School of Design and Environment. A progressive web application that collects subtle momentary thermal and environmental comfort assessments while occupants learn about the sustainability features of the new Net Zero Energy SDE4 Building.
