ISO 10211:2007 Thermal bridges in building construction -- Heat flows and surface temperatures -- Detailed calculations. Test case A.1 validation. - QuickField simulation example
QuickField validation of the test case A.1 presented in ISO 10211:2007 Thermal bridges in building construction.
How to find thermal bridge heat flow iso 10211 case a.1?
Answer Typical applications Geometry
Width w = 4 m, height h = 8 m.
Given
Task
Results
Temperature calculated in QuickField is presented in the table below (reference temperatures are shown in the brackets). To comply with the ISO 10211:2007 the difference between calculated and reference temperatures should be less than 0.1°K. This simulation accuracy complies with the requirements of ISO 10211:2007.
