Rename article
"Building energy simulation" is an old term from a time when software was only capable to predict energy use in buildings.

Nowadays, it is called "Building performance simulation", because it is not only about energy use anymore but more other performance aspects.

Also the professional association is called "International building performance simulation association"

This article was renamed. Daniel.ruepp (talk) 10:47, 29 March 2018 (UTC)

Why ISO13790 is not considered as "simulation"
Scientific literature mostly refer to ISO 13790 as "calculation" and not "simulation". There are several limitations in this standard, especially the use of simplified algebraic equations and "utilization factors" are the main reason why it is not considered as "simulation".


 * The ISO 13790 standard uses simple algebraic equations, while dynamic simulation is focused on transient behavior of systems and buildings.
 * The calculation of heating and cooling requirements can be carried out by the standard EN ISO 13790, which defines a simplified monthly or seasonal procedures that do not take into account the actual dynamic variation of thermal loads. In particular, thermal losses are determined by considering the daily average outdoor temperature, as well as energy gains that are evaluated by monthly daily average values concerning the incident solar radiation. Moreover, the standard assumes a constant indoor air temperature and a continuous operation regime of the air-conditioning plant for the whole calculation period. These calculations are clearly not accurate, but result useful for energy characterization and energy labelling of buildings. Instead, they are inaccurate for assessing the actual energy consumption in function of climatic zone, construction type and profile use.
 * [...] However, due to the simplicity of the method, dynamic effects (e.g. climatic conditions, user behaviour, time schedules, …) are only considered in a simplified way by time weighted averaged values and dynamic factors.

Please provide evidence that this is actually a transient simulation before you change the article again. Otherwise please create an article about ISO13790 and include the relevant tools in that article. Daniel.ruepp (talk) 21:36, 22 September 2018 (UTC)
