Abstract: Overall heat transfer coefficient or thermal transmission coefficient or U-value is an important tool for thermal characterisation of any building material. The guarded hot box test facility is used for evaluation of U-value of any material. In this paper a detailed insight has been given into the overall control strategy to be implemented for maintaining a constant low temperature inside the cold box of a guarded hot box test facility. Thereafter impacts of varying control parameters of the controller on the overall system performance have also been given.
