The International Conference on Systems for Energy-Efficient Buildings, Cities, and Transportation (ACM BuildSys) is a highly selective, single-track forum for research on systems issues covering all aspects of the built environment, broadly defined. The 12th ACM International Conference on Systems for Energy-Efficient Buildings, Cities, and Transportation (BuildSys’25) will be held on November 20-21, 2025, in Golden, Colorado, USA. BuildSys’25 will provide a venue for researchers and practitioners to present research results, share experiences, and participate in the development of systems that address the interdependence of buildings, cities, and transportation. We invite submissions of original, previously unpublished work in the relevant areas.

Targeted Topics
Relevant topics for BuildSys '25 include, but not limited to the following:

AI/ML, large foundation models, and data analytics for the built environments
Collaborative sensing systems for built environments with AI-driven inference models
Design and operation of low-carbon and sustainable systems in built environment
Applications in smart and connected communities
Modeling, simulation, optimization, and control of heating, cooling, lighting, ventilation, water usage, and other resource flows in built environments
Reliable and scalable occupant information inference in built environments
Emerging standards for data collection, energy control, or interoperability of disparate devices or systems
Building automation system metadata models and inference techniques
Improved user interfaces to built infrastructure
Human in the loop sensing and control for efficient building energy systems
Sensor systems and applications impacting the health, wellness, safety, or comfort of humans in built environments
Enhancing energy efficiency, energy reliability, durability, and comfort via Cyber-Physical Systems and Internet of Things
Sensing, modeling, and predicting for urban infrastructure and transportation
Integration of smart grids with built environments
Distributed generation, alternative energy, renewable sources, and energy storage in buildings
Long-lived and energy-harvesting sensor systems
Security, privacy, safety, and reliability in the context of built environment
Smart building and city technologies and initiatives in developing countries
Vehicle, mobility, and traffic-related technologies
Scalable indoor localization, contextual computing, and city-scale wireless communications
Paper Types
We solicit two types of original submissions:

Regular papers for oral presentation (10 pages max)
Notes papers for oral presentation (4 pages max)
Notes papers are 4-page papers intended to discuss preliminary research results, advocate new research directions, describe public software or datasets, or present short projects that do not warrant a 10-page paper. Notes papers serve, in part, to encourage younger researchers and research teams entering this field of research to share their work. We also encourage Notes paper submissions from industry participants who may not be able to devote resources to a full paper. While Notes papers are not expected to have extensive evaluations, they will be reviewed based on the novelty of their ideas, potential for impact, and quality of presentation.

Submission Guidelines
Submitted papers must be unpublished and must not be currently under review for any other publication. Submissions must be full papers, at most 10 single-spaced US Letter (8.5” x 11”) pages, including figures, tables, references, and appendices. Submissions for Note papers must be at most 4 single-spaced US Letter (8.5”x11”) pages, including figures, tables, references, and appendices. All submissions must use the LaTeX (preferred), or Word styles found here. Please, use the template “sigconf”.

The Buildsys review procedure will follow a standard double-blind policy. As an author, you should not identify yourself in the paper either explicitly or by implication (e.g., through the references or acknowledgments). Authors must make a good faith effort to anonymize their submissions by (1) using the “anonymous” option for the class and (2) using “anonsuppress” section where appropriate.

Papers that do not meet the size, formatting, and anonymization requirements will not be reviewed. Please note that ACM uses 9-pt fonts in all conference proceedings, and the style (both LaTeX and Word) implicitly define the font size to be 9-pt. Please refer to this former publication chair's Note as well as the User Guide of the new class. Accepted submissions will be available on the ACM digital library on the first day of the conference.

Submission Link
All papers must be in Adobe Portable Document Format (PDF) and submitted through the HotCRP platform for this conference: https://buildsys25.hotcrp.com/.

Authors Take Note
The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work.

Journal Fast Track
Selected papers will be fast tracked to both a special issue of Data-Centric Engineering (DCE) from Cambridge Press and a special issue of ACM Transactions on Sensor Network (TOSN).
