title = "Steady-state or transient heat balances for comparable energy demand calculations? A case-study based on a sandwich lightweight structure",
abstract = "Energy demand calculations are very common nowadays due to various regulations and assessment methods around the world. Depending on local regulations they are usually carried out with either simplified steady-state energy balances or with dynamic simulations. Hereby, most stead-state calculations are based on the same temperature difference between inside and outside over a whole heating period or on monthly mean values compared to hourly data for transient calculations. In a case study on a sandwich-lightweight structure it became evident that dynamic calculations with transient weather data show results where the energy demand is approximately up to 50 % lower than steady-state calculations according to a German standard. Therefore, steady-state calculations cannot be recommended without restriction e.g. for sustainability assessment.",
