• Abstract summary: This work proposes a new method which can estimate a building's energy efficiency using purely remotely sensed data. We find that in the binary setting of distinguishing efficient from inefficient buildings, our end-to-end deep learning model achieves a macro-averaged F1-score of 62.06%.

• Abstract: In the race towards carbon neutrality, the building sector has fallen behind and bears the potential to endanger the progress made across other industries. This is because buildings exhibit a life span of several decades which creates substantial inertia in the face of climate change. This inertia is further exacerbated by the scale of the existing building stock. With several billion operational buildings around the globe, working towards a carbon-neutral building sector requires solutions which enable stakeholders to accurately identify and retrofit subpar buildings at scale. However, improving the energy efficiency of the existing building stock through retrofits in a targeted and efficient way remains challenging. This is because, as of today, the energy efficiency of buildings is generally determined by on-site visits of certified energy auditors which makes the process slow, costly, and geographically incomplete. In order to accelerate the identification of promising retrofit targets, this work proposes a new method which can estimate a building's energy efficiency using purely remotely sensed data such as street view and aerial imagery, OSM-derived footprint areas, and satellite-borne land surface temperature (LST) measurements. We find that in the binary setting of distinguishing efficient from inefficient buildings, our end-to-end deep learning model achieves a macro-averaged F1-score of 62.06\%. As such, this work shows the potential and complementary nature of remotely sensed data in predicting building attributes such as energy efficiency and opens up new opportunities for future work to integrate additional data sources.

  Building Energy Rating (BER) stands as a pivotal metric, enabling building owners, policymakers, and urban planners to understand the energy-saving potential through improving building energy efficiency. Yet, the BER assessment process is vulnerable to missing and inaccurate measurements. We introduce ttCLEAR, a data-driven approach designed to scrutinize the inconsistencies in BER assessments through self-supervised contrastive learning.

  This paper presents a building point cloud dataset that promotes a data-driven, large-scale understanding of the 3D representation of buildings and their energy characteristics. We generate building point clouds by intersecting building footprints with geo-referenced LiDAR data and link them with attributes from UK's energy performance database. To achieve a representative sample, we select one million buildings from a range of rural and urban regions across England, of which half a million are linked to energy characteristics.
