Semantic segmentation of longitudinal thermal images for identification of hot and cool spots in urban areas

no code implementations6 Oct 2023 Vasantha Ramani, Pandarasamy Arjunan, Kameshwar Poolla, Clayton Miller

The masks generated using the segmentation models were then used to extract the temperature from thermal images and correct for differences in the emissivity of various urban features.

The rooftop infrared thermography observatory with a multi-modal platform that is capable of assessing a wide range of dynamic processes in urban systems was deployed in Singapore.

Longitudinal thermal imaging for scalable non-residential HVAC and occupant behaviour characterization

no code implementations17 Nov 2022 Vasantha Ramani, Miguel Martin, Pandarasamy Arjunan, Adrian Chong, Kameshwar Poolla, Clayton Miller

It is observed that for the water-cooled system, the difference between the rate of change of the window and wall can be used to extract the operational pattern.

LEAD1.0: A Large-scale Annotated Dataset for Energy Anomaly Detection in Commercial Buildings

1 code implementation30 Mar 2022 Manoj Gulati, Pandarasamy Arjunan

Modern buildings are densely equipped with smart energy meters, which periodically generate a massive amount of time-series data yielding few million data points every day.
