Paper Abstract

Lack of reliable operational methods makes it difficult for potential users to benefit from infrared survey systems which are already well tested technically. In order to develop operational routines for the use of thermography for building and district heating network applications, airborne, mobile and handheld infrared systems have been tested in two different investigation areas. Provided that perturbing factors were taken into consideration and surveys were made during stable weather conditions, with low windspeed, the infrared system tested was found to have good accuracy and low operational cost. An aircraft equipped with an infrared line scanner (8-14 μm) seems to be the best system for surveying larger areas, while helicopter and mobile thermovision systems (8 - 14 μm), are preferable for smaller investigation areas. The best way to analyze thermograms seems to be with an interactive computer-based image analysis systems.
