Through the use of an integrated lidar and thermal infrared TIR ground-based sensor, the Cold Regions Research and Engineering Lab CRREL conducted a survey at Palmer Station, Antarctica, in October 2015 to assess thermal building envelopes of the main infrastructure. These co-registered data produce three-dimensional models with assigned temperature values of target buildings, useful in spatially identifying thermal anomalies and areas for potential improvements in building construction e.g., insulation, soffits, windows, doors, etc.. For Palmer Station, the National Science Foundation identified three focus buildings Biolab, Garage-Warehouse-Recreation GWR, and Terralab. The lidarTIR data collection was conducted in tandem with interior and exterior temperature and atmospheric measurement logging, handheld thermal and electro-optical imagery collection, and Global Navigation Satellite System GNSS real-time kinematic surveys to place the collected data in a global coordinate system. This report details the findings of these efforts and summarizes the results for each of the three focus buildings. In general, the more recently constructed Terralab exhibits a sounder building envelope without any major thermal deficiencies when compared to both the Biolab and GWR buildings. The three-dimensional models of all buildings allow for a holistic view of these thermal deficiencies and provide a means for prioritizing potential construction activities.
