Functionality of Ventilated Facades: Protection of Insulation

Currently, in the Republic of Khakassia, much attention is paid to research aimed at reducing air pollution due to fuel combustion. In this aspect, the issue of increasing the energy efficiency of buildings is relevant. The use of ventilated facade systems with an air gap makes it possible to improve the energy efficiency class of buildings and modernize the facades. However, these facade systems have weak points that require detailed and high-quality study. Often, design solutions are used that are used in warm climates without taking into account the peculiarities of a cold climate - frequent changes in temperature, humidity, wind loads, and other influences, which can lead to negative manifestations. Facade systems with a ventilated air gap must provide the ability to monitor the operability of all system elements and, if necessary, carry out repair and reconstruction work with minimal operating costs. The article presents an analysis of the thermal properties of an external fence using a hinged facade structure. The influence of installation defects and heat-conducting inclusions on the heat-shielding properties of the building envelope is shown. It was determined that during operation the moisture-windproof membrane loses its vapor-permeable properties.

El uso generalizado de fachadas opacas ventiladas, hace que la investigación de su rendimiento térmico sea relevante porque existe la necesidad de una evaluación objetiva de su eficiencia energética en la etapa operativa. El artículo está dedicado a la investigación experimental a gran escala de las características térmicas de una cavidad de aire del sistema de fachada ventilada de forma natural con juntas cerradas, bajo condiciones extremas de viento, comparando las características térmicas de la cavidad de aire, se basa en cálculos que cumplen con los estándares de construcción y en los resultados del experimento a escala. Se utilizaron equipos de medición Testo 435 y 417. Se obtuvo una ecuación empírica aproximada entre la velocidad del viento cuando es superior a 7 m/s y la velocidad del aire de la cavidad. Un aumento en la velocidad del viento a lo largo de la pared conduce a un aumento en la velocidad del aire de la cavidad, que se acerca a 1-1.5 m/s y una disminución en la resistencia térmica. Los resultados del cálculo, se pueden usar para el control experimental de las características térmicas de la fachada con el fin de cumplir con una auditoría energética multidisciplinaria del edificio.
