What is changed by introducing the ISO 10077-2:2017?
By introducing the new ISO 10077-2:2017 one of the things which has changed most is the process of calculation heat flow in cavities of Window and facade profile. As an alternative to the simplified model of equivalent heat conductivity the new standard defined a new model which is using detailed heat radiation. This heat radiation model is named „Radiosity”.
EN ISO 10077-2 preparation with cavity model
WinIso® analyses and edits the drawing not just automatically related to the valid standard DIN EN ISO 10077-2:2012, also the detailed radiation model „Radiosity” by the new ISO 10077-2:2017 is included. So you are able to calculate parameters like the Uf by using the old standard of 2012 as well as the standard of 2017.
