Energy consumption of buildings depends significantly on the criteria used for design and operation. Therefore, thermal insulation of building structures is a topic of fundamental importance in building design and the acoustic protection of internal environment is often considered less important or feasible in a subsequent design time, as a consequence of thermal issue. The main problem about acoustic and thermal performances of building elements is that it's very hard to optimize both performances in the same time because of the different physics phenomena related to these two aspects. In this work several aspects of acoustic and thermal design are evaluated, with the aim of balancing overall performances. A comparative analysis was performed for the evaluation of the interaction between several approaches to building design. Different types of insulating materials and construction techniques have been used in the same case study and possible correlations between thermal and acoustic performances have been evaluated. Results show that thermal and acoustic design optimization have to take into account field transient conditions as well as structural joints, because the simple comparison between physical properties of heat and sound transmission of building materials in stationary conditions is not sufficient for establish clear correlation.
