The increasing energy efficiency of the thermal envelop induces evolutions in the whole energetic equilibrium of buildings. This paper illustrated some of these evolutions regarding internal and solar gains through dynamic simulations. The increased relative impact of internal gains compared to solar gains is shown, such as a reduction in the utilization of solar gains during the heating period. The accuracy of ISO 13790:2008 calculation method facing these evolutions is discussed.
