This study concerns an overall evaluation of building envelopes, for what concerns the energy, acoustic and lighting performances. It combines different topics of energy and indoor comfort, with the aim to improve the livability of an existing building (a social housing) by means of a comprehensive retrofit of their envelopes. The novel contribution of this study is to apply some methods for energy retrofit of a building envelope in such a way that objectives are achieved within the state-of-the-art combination simulation, optimization approaches, and equations describing the calculations of sound insulation in buildings. The results showed that properties of building envelope like the value of transmittance of the glass window and thermal properties of materials have an impact on indoor environmental quality and energy performance.
