BuildSys 2021
The 8th ACM International Conference on Systems for Energy-Efficient Buildings, Cities, and Transportation

November 17-18, 2021 in Coimbra, Portugal

About The Event

About The Event

The 8th ACM International Conference on Systems for Energy-Efficient Built Environments (BuildSys 2021) will host a highly selective, single-track forum for research on systems issues covering all aspects of the built environment, broadly defined.

Advances in the effective integration of networked sensors, building controls, and physical infrastructure are transforming our society, allowing the formation of unprecedented built environments and interlocking physical, social, cyber challenges. Moreover, built environments, including buildings and critical urban infrastructure, account for over half of societys energy consumption and are the mainstay of our nation’s economy, security and health. As a result, there is a broad recognition that systems optimizing explicitly for the built environment are particularly important in improving our society, and represent the foundation for emerging "smart cities".

BuildSys is an ideal venue for researchers and practitioners working to develop and optimize such smart infrastructure systems that are driven by networked sensing, computing, and control functions.

BuildSys 2021 will be Hybrid - Both Physical and Virtual.

BuildSys is one of the primary conferences sponsored by ACM SIGEnergy.

Built environments and critical urban infrastructures, account for over half of society’s energy consumption and are the mainstay of our nation’s economy, security and health. Advances in the effective integration of networked sensors, building controls, and physical infrastructure are transforming our society. In the information age, unprecedented research of cyber physical infrastructures includes: the acquisition, integration, and analysis of big and heterogeneous data such as sensors, devices, vehicles, buildings, and human, to tackle the major issues that cities face, e.g., air pollution, increased energy consumption and traffic congestion.

Systems optimization, data analysis and modeling applied to the built environment are particularly important in improving our society, e.g., by increasing its sustainability and enhancing people’s quality-of-life. These systems represent the foundation for emerging “smart cities”.

The 8th ACM International Conference on Systems for Built Environments (BuildSys'21) will be held November 17-18, 2021 in Coimbra, Portugal.

BuildSys is the premier conference for researchers and practitioners working to develop and optimize smart infrastructure systems that are driven by sophisticated sensing, computing, and control functions. We invite original contributions including, but not limited to the following:

  • Applications in smart and connected communities;
  • Sensing and control for urban infrastructure systems;
  • Novel sensor methodologies, techniques, and tools;
  • Sensing and control of electrical, gas, and water loads;
  • Improved user interfaces to built infrastructure;

Paper Types

We solicit two types of original submissions:

  • Regular papers for oral presentation (10 pages)
  • Notes papers for oral presentation (4 pages)

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 that 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. 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 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.

A subset of the best conference papers will be fast-tracked to the ACM Transactions on Sensor Networks (TOSN).

All papers must be in Adobe Portable Document Format (PDF) and submitted through the web submission form. For notes papers, the submission site has a checkbox called "Notes papers." Those who submit notes papers need to check this box to indicate their paper types.

Title: Perception Matters: Moving Beyond Sensing in the IoT

Abstract

The Internet of Things (IoT) has gone from vision to reality in less than two decades. Hundreds of billions of sensor and actuator devices are now connected to the Internet to help create a better and more efficient planet. However, many of the benefits of the IoT are still yet to be realized. To unlock its full potential, we must move beyond sensing and produce comprehensive approaches for perception: the integration and interpretation of sensor data in order to create a representation of the world. This talk dives into one domain of the IoT – home automation – to explore the opportunities and challenges of perception in the IoT.



Prof Zoran Kapelan is the Head of Urban Water Infrastructure Group at Delft University of Technology in the Netherlands. He also holds the professorial position at the University of Exeter in United Kingdom where he was heading the Water and Environment group previously. He is an IWA Fellow with over 30 years of research and consulting experience in water engineering. His research interests cover a wide range of issue across the urban water cycle including smart water systems and related technologies. Prof Kapelan has developed several AI-based technologies that are used by water utilities resulting in major cost savings and other benefits. He has (co)authored over 400 technical publications and has given many invited talks around the world. Further information available at http://homepage.tudelft.nl/b2v1b/index.html.

Smart urban water infrastructure: Past, Present and Future

Abstract

The talk will start with introductory remarks about the urban water infrastructure and its key characteristics, including a brief note about the past evolution of related drinking water and urban drainage systems. This will be followed by a summary of main drivers and challenges that these systems are facing now and in the future. The concept of smart water systems will be introduced, in the context of smart cities. This will be followed by the presentation of examples of smart water solutions that are typically based on extraction of useful information from different data sources by using Artificial Intelligence and Machine Learning type methods. One such example involves the award winning burst/leak detection technology that is now used companywide by a large UK water utility resulting in multi-million euros annual savings via reduced operational costs. The talk will end with concluding remarks about the potential of smart water technologies to improve existing and future water infrastructure systems.

1st ACM SIGEnergy Workshop on Fair, Accountable, Transparent, and Ethical (FATE) AI for Smart Environments and Energy Systems

With the advent of IoT, high performance computing, and ubiquitous and smart sensing, the SenSys/BuildSys community is noticing a big shift in the adoption of data-driven black-box modeling (also referred to as AI) to solve problems in the space of smart environments and energy systems. As a result, these AI-enabled systems for smart buildings, smart cities, smart grids, electric transportation, among others are attaining better accuracy and efficiency numbers every year. However, these data-driven black-box solutions are rarely held accountable for the impact of their actions on the human in the loop which significantly impacts their real-world adoption. To truly conceptualize the idea of smart systems for everyone, it is critical to study AI-enabled smart environments and energy systems to enforce energy equity and ensure not just clean and resilient energy systems, but also make them affordable and accessible for all. The first ACM SIGEnergy workshop on Fair, Accountable, Transparent, and Ethical AI for Smart Environments and Energy Systems intends to bring together researchers from diverse backgrounds and discuss key issues, challenges, breakthroughs, and socio-economic impact in developing fair, accountable, transparent and ethical AI techniques for smart environments and energy systems.

1st ACM International Workshop on Big Data and Machine Learning for Smart Buildings and Cities

The proliferation of urban sensing, IoT, and big data in buildings, cities, and urban areas provides unprecedented opportunities for a deeper understanding of occupant behavior, transportation, and energy and water usage patterns. However, utilizing the existing data sources and modeling methods in building science to model urban scale occupant behaviors can be pretty challenging. Therefore, technological progress is needed to unlock its full potential. In order to fulfill the latter task, this workshop focuses on the methodologies for big urban and building data collection, analytics, modeling, and real-world technology deployment. Additionally, a spotlight will be put on the ongoing project IEA EBC Annex 79 Subtask 2: Data-driven occupant modeling strategies and digital tools.

The workshop aims to open up discussions on 1) challenges of the current modeling approaches in building science, 2) big data modeling paradigms that could be applicable in building science, urban infrastructure data modeling, 3) requirements on the data collection infrastructure required for increasing the volume of data collection, and 4) future research directions using urban big data. An important part of the workshop will be dedicated to accelerating the open-world deployment of developed technologies. For instance, how can the guidelines, model benchmarking, and standardization unlock the potential of the big data, buildings, urban scale occupant behavior modeling and energy consumption data.





4th ACM DATA Workshop, the Data: Acquisition To Analysis (DATA)

As the enthusiasm for and success of the Internet of Things (IoT), Cyber-Physical Systems (CPS), and Smart Buildings grows, so too does the volume and variety of data collected by these systems. How do we ensure that this data is of high quality, and how do we maximize the utility of collected data such that many projects can benefit from the time, cost, and effort of deployments?

The Data: Acquisition To Analysis (DATA) workshop aims to look broadly at interesting data from interesting sensing systems. The workshop considers problems, solutions, and results from all across the real-world data pipeline. We solicit submissions on unexpected challenges and solutions in the collection of datasets, on new and novel datasets of interest to the community, and on experiences and results—explicitly including negative results—in using prior datasets to develop new insights.

The workshop aims to bring together a community of application researchers and algorithm researchers in the sensing systems and building domains to promote breakthroughs from integration of the generators and users of datasets. The workshop will foster cross-domain understanding by enabling both the understanding of application needs and data collection limitations.

  • How to get to Coimbra

    Coimbra is located 180 km north of Lisbon and 120 km south of Porto. The best way to get to Coimbra is to fly to Lisbon or Porto, and then rent a car or take a train.

    Driving from Lisbon

    On the way out of the Airport follow the signs for "A1", heading north. After 180 km, exit at "Coimbra Sul".

    Traveling by train from Lisbon

    To get to the “Lisboa-Oriente” railway station you can take the metro (3 stops away from the airport, 1.5 €) or take a taxi (10 min., around 10 €). If you choose to go by metro, beware that the line for the ticket machines may be long. If you choose to go by taxi, as the ride from the airport to the train station is very short, it is advisable to take a taxi outside the departure hall, instead of taking it in the arrivals area.

    Once you arrive at "Lisboa-Oriente" train station, go to the upper ticketing level and buy a ticket for an “Alfa Pendular” (AP) or “InterCidades” (IC) train. Do not take regional trains (R), as they may take 3 hours to reach Coimbra.

    Trains depart approximately every half hour, and the journey takes 1H30m to 1H50m, depending on the type of train. Please note that the last daily train departs between 21:30 and 22:00, depending on the day (timetables are available at: https://www.cp.pt/passageiros/en/train-times).

    Get off the train at “Coimbra B”. Either take a taxi directly to your Hotel (it should cost less than 10 €) or take a local train to “Coimbra A” (downtown station), using your previous ticket (this transfer is included in the ticket price).

    Driving from Porto

    On the way out of the Airport follow the signs for "A1", heading south. Exit at "Coimbra Sul".

    Traveling by train from Porto

    From the airport, which lies to the north of the town, take a taxi or the Metro E line to Estação Campanhã. Depending on the traffic, this might take up to an hour. Take an “Alfa Pendular” or “Intercidades” train. These trains depart approximately every half hour. Please note that the last daily train departs at around 20:00, depending on the day (timetables available at: https://www.cp.pt/passageiros/en/train-times).

    Get off the train at “Coimbra B”. Either take a taxi directly to your Hotel (it should cost less than 10 €) or take a local train to “Coimbra A” (downtown station), using your previous ticket (this transfer is included in the ticket price).
