Abstract
The current issues of excess heat losses by construction projects are identified and analyzed. It is established that the heat loss of buildings depend on the thermal qualities of external building structures of different materials, the main of which are density, humidity, thermal conductivity. In this regard, practical methods for identifying temperature and humidity fields of the surfaces of building structures in the mode of their operation are of particular importance. The technical capabilities of modern thermal imaging equipment for obtaining and processing thermograms of thermal imaging of the controlled object are presented. A practical example of thermal definition and analysis of temperature and humidity fields of translucent enclosing building structures in the form of a window in a window opening is given. It is confirmed that thermal imaging diagnostics is able to state the distribution of heat losses in the control zone. On the basis of this knowledge, measures are developed to reduce them (alignment) and subsequently assess the effectiveness of their implementation

Summary
ТЕПЛОВИЗИОННЫЙ МЕТОД ОПРЕДЕЛЕНИЯ ВЛАЖНОСТНЫХ ПОЛЕЙ ПОВЕРХНОСТЕЙ СТРОИТЕЛЬНЫХ КОНСТРУКЦИЙ ЗДАНИЙ И СООРУЖЕНИЙ Установлено, что потери теплоты зданиями зависят от теплотехнических качеств наружных строительных конструкций из различных материалов, основными из которых являются плотность, влажность, теплопроводность. В связи с этим, особую значимость и важность приобретают практические методы идентификации температурных и влажностных полей поверхностей строительных конструкций зданий и сооружений в режиме их эксплуатации. Представлены технические возможности современного тепловизионного оборудования по получению и обработке термограмм тепловизионной съемки контролируемого объекта.
