description |
One of the primary problems solved for increasing energy efficiency of a building is
increasing of the insulating properties of the building envelope. The paper describes the method for
determining the coefficient of thermotechnical uniformity by analyzing a thermogram of parts of a building
envelope. The method is based on obtaining temperature distribution matrix on the surface of a building
envelope fragment by thermography. Two methods for assessing the coefficient of thermotechnical
uniformity are proposed. One method for determining the coefficient of thermotechnical uniformity is
based on obtaining mean temperature values by numerically processing thermograms, another on
numerical integration along the contour lines of temperature curves. |
