  text: Decarbonizing industrial process heat is a crucial step in mitigating climate
    change. While Process Mining (PM) has gained traction in sustainability research—such
    as optimizing production scheduling to reduce energy use or accounting for carbon
    footprints—it has largely overlooked the challenges and opportunities related
    to thermal energy, accounting for 66% of total energy demand in industrial processes.
    At the same time, Heat Integration (HI) is an established engineering discipline
    focused on maximizing the efficiency of thermal energy systems. However, HI traditionally
    relies on static or incomplete data about energy demands, limiting its effectiveness
    and accuracy. In this paper, we propose a novel framework that combines PM and
    HI to enable data-driven, process- and product-centric modeling of industrial
    energy demands. By integrating event logs and thermal energy data, our approach
    allows for a fine-grained analysis of heat demand patterns corresponding to specific
    process activities and product variants. We demonstrate the applicability and
    advantages of the framework by simulating a pharmaceutical manufacturing process
    and evaluating energy demands and heat recovery potentials. Our findings show
    that our PM-enabled HI framework provides more accurate and actionable insights
    into the temporal and product-specific variation of thermal energy demands. By
    capturing the causal relationships between process activities, product characteristics,
    and energy consumption, our approach enables improved analysis, planning, and
    optimization for heat recovery and process decarbonization. This integration of
    PM and HI expands the analytical tools for both disciplines and contributes to
    advancing the sustainable transformation of industrial processes.

  text: Data centers (DCs) form the backbone of our growing digital economy, but their
    rising energy demands pose challenges to our environment. At the same time, reusing
    waste heat from DCs also represents an opportunity, for example, for more sustainable
    heating of residential buildings. Modeling and optimizing these coupled and dynamic
    systems of heat generation and reuse is complex. On the one hand, physical simulations
    can be used to model these systems, but they are time-consuming to develop and
    run. Machine learning (ML), on the other hand, allows efficient data-driven modeling,
    but conventional correlation-based approaches struggle with the prediction of
    interventions and out-of-distribution generalization. Recent advances in causal
    ML, which combine principles from causal inference with flexible ML methods, are
    a promising approach for more robust predictions. Due to their focus on modeling
    interventions and cause-and-effect relationships, it is difficult to evaluate
    causal ML approaches rigorously. To address this challenge, we built a testbed
    of a miniature DC with an integrated waste heat network, equipped with sensors
    and actuators. This testbed allows conducting controlled experiments and automatic
    collection of realistic data, which can then be used to benchmark conventional
    and causal ML methods. Our experimental results highlight the strengths and weaknesses
    of each modeling approach, providing valuable insights on how to appropriately
    apply different types of machine learning to optimize data center operations and
    enhance their sustainability.

  text: Data centers (DCs) form the backbone of our growing digital economy, but their
    rising energy demands pose challenges to our environment. At the same time, reusing
    waste heat from DCs also represents an opportunity, for example, for more sustainable
    heating of residential buildings. Modeling and optimizing these coupled and dynamic
    systems of heat generation and reuse is complex. On the one hand, physical simulations
    can be used to model these systems, but they are time-consuming to develop and
    run. Machine learning (ML), on the other hand, allows efficient data-driven modeling,
    but conventional correlation-based approaches struggle with the prediction of
    interventions and out-of-distribution generalization. Recent advances in causal
    ML, which combine principles from causal inference with flexible ML methods, are
    a promising approach for more robust predictions. Due to their focus on modeling
    interventions and cause-and-effect relationships, it is difficult to evaluate
    causal ML approaches rigorously. To address this challenge, we built a testbed
    of a miniature DC with an integrated waste heat network, equipped with sensors
    and actuators. This testbed allows conducting controlled experiments and automatic
    collection of realistic data, which can then be used to benchmark conventional
    and causal ML methods. Our experimental results highlight the strengths and weaknesses
    of each modeling approach, providing valuable insights on how to appropriately
    apply different types of machine learning to optimize data center operations and
    enhance their sustainability.
