A schematic of selected opportunities to reduce greenhouse emissions from buildings and cities using machine learning. From "Tackling Climate Change with Machine Learning."[1]

Buildings offer some of the lowest-hanging fruit when it comes to reducing GHG emissions. While the energy consumed in buildings is responsible for a quarter of global energy-related emissions,[2] a combination of easy-to-implement fixes and state-of-the-art strategies could reduce emissions for existing buildings by up to 90%.[3] It is possible today for buildings to consume almost no energy.[4] Many of these energy efficiency measures actually result in overall cost savings[5] and simultaneously yield other benefits, such as cleaner air for occupants. This potential can be achieved while maintaining the services that buildings provide – and even while extending them to more people, as climate change will necessitate. For example, with the changing climate, more people will need access to air conditioning in regions where deadly heat waves will become common.[6][7]

Two major challenges are heterogeneity and inertia. Buildings vary according to age, construction, usage, and ownership, so optimal strategies vary widely depending on the context. For instance, buildings with access to cheap, low-carbon electricity may have less need for expensive features such as intelligent light bulbs. Buildings also have very long lifespans; thus, it is necessary both to create new, energy-efficient buildings, and to retrofit old buildings to be as efficient as possible.[8] Urban planning and public policy can play a major role in reducing emissions by providing infrastructure, financial incentives, or energy standards for buildings.

Machine learning provides critical tools for supporting both building managers and policy makers in their efforts to reduce GHG emissions. At the level of building management, ML can help select strategies that are tailored to individual buildings, and can also contribute to implementing those strategies via smart control systems.[1] At the level of urban planning, ML can be used to gather and make sense of data to inform policy makers. In addition, ML can help cities as a whole to transition to low-carbon futures.[1]

Machine Learning Application Areas

Optimizing buildings

  • Modeling building energy: A better understanding of how energy is used within buildings can help inform efficiency-promoting interventions. For example, there are opportunities to improve energy demand forecasts, disaggregation of appliance energy consumption, and characterization of efficiency measures.
  • Smart buildings: Machine learning can inform optimal control for systems within buildings, allowing reductions in energy use. For example, model-predictive control can increase the efficiency of HVAC systems.

Urban planning

  • Modeling energy use across buildings: District-level modeling of building energy use can lead to even greater efficiency improvements, compared to modeling of individual buildings, because they can support district heating and cooling as well as target retrofit campaigns.
  • Gathering infrastructure data: Machine learning can support data generation of relevant infrastructure data, transforming raw street-view or satellite imagery into estimates of climate-critical metrics, like prevalence of photovoltaic adoption or change in building footprints.

The future of cities

  • Data for smart cities: A variety of city services are now guided by data streams coming from dedicated sensors (e.g., traffic cameras) or indirectly through sources like mobile phones. These services can help inform actions to reduce energy footprints and increase resilience.
  • Low-emissions infrastructure: Machine learning can strengthen the ties between the different components of urban infrastructure, like public transportation and building developments, in a way that reduces overall carbon footprints.
