Simulating Heat Transfers through the Building Envelope: A Useful Tool in the Economical Assessment

The thermal performance of building plays a fundamental role in energy consumption since a large amount of energy is needed to balance heat transfers occurring through the envelope itself. The aim of the present paper is to simulate the heat transfer affecting a specific building envelope considering two different scenarios: current situation and future improvements by replacing transparent enclosures and adding an exterior insulation of different thicknesses. In order to identify the most convenient and suitable solution and to focus the attention on the most compelling action, an economical assessment is carried out taking into account the national incentives.
