Recent advances in Unmanned Aerial Systems UAS also known as drones bring great opportunities for monitoring and inspection in industries such as infrastructure and construction, forestry and agriculture, transportation, security and insurance, telecommunications and mining, among others. According to PwC’s study on commercial applications of drone technology, the emerging global market for business services using drones is valued to over 115 billion EUR. The UAS/drones allow for use of various types of cameras enabling aerial remote sensing.
One of the challenges when seeking to improve energy efficiency is the identification of thermal leaks in the residential and industrial building envelopes, e.g. regions with excessive infiltration and exfiltration and thermal bridges, windows, insufficient air sealing and other insulation faults. Inspection of buildings by traditional ground thermography instrumentation is often time consuming, inaccurate, complicated, dangerous or inaccessible, including multistory or large-span building envelopes as well as building roofs. Thus, UAS/drone equipped with a thermal infrared imaging system provides a great opportunity for efficient and accurate analysis of building envelopes, reducing operational costs and safety risks while giving unique aerial perspectives.

Proposed tasks:
Activities may include visual and thermal inspection of standalone as well as on-roof photovoltaic installations to detect overheating, damages or soiling of the panels. One of the proposed applications is also to detect leakages in the district heating network by thermal camera. The important part of the activities is also to calibrate the thermal camera to provide results with high accuracy. Furthermore, we may perform aerial thermography measurements of different types of buildings. We will specifically look for issues such as thermal leaks, exfiltration and infiltration, missing or deteriorated insulations thermal bridges and other regions of building envelope failure. Other possible applications are inspection of boiler buildings, chimneys, tracking of the plume, power lines and power stations, leaks in district heating network etc.
