Abstract: Lime renders can help improve the energy balance of the building itself given their position in the external layer. Indeed, historical masonries have high rates of thermal transmittance; however, their thermal inertia can contribute to their effectiveness in areas with important temperature fluctuations. Hence, it is possible to preserve this thermal inertia if the transfer rate of energy is improved from outside. There are many commercial systems (SATE or ETICS) which improve the thermal efficiency of outer walls by reducing heat conduction, but they require a considerable increase of the thickness of the wall. However, in façades where it is not possible there seems to be no available solution. This paper analyses how the energy balance in a building can be improved based on a render that works not only on reducing thermal conductivity but on optimizing heat transfer by radiation.
