Verification of calculation code THERM in accordance with BS EN ISO 10077-2Nammi, Sathish K.; Shirvani, Hassan; Shirvani, Ayoub; Edwards, Gerard; Whitty, Justin P. M.; Anglia Ruskin University, Anglia Ruskin University, Anglia Ruskin University, University of Chester, University of Central Lancashire (Anglia Ruskin Research Online, 2014)Calculation codes are useful in predicting the heat transfer features in the fenestration industry. THERM is a finite element analysis based code, which can be used to compute thermal transmittance of windows, doors and shutters. It is important to verify results of THERM as per BS EN ISO 10077-2 to meet the compliance requirements. In this report, two-dimensional thermal conductance parameters were computed. Three versions of THERM, 5.2, 6.3 and 7.1, were used at two successive finite element mesh densities to assess their comparability. The results were all compliant with the aforementioned British Standard.
