predictive model

In many countries, the traditional method of ventilating dwellings involved natural ventilation, based on the operation of windows and high levels of infiltration through the building envelope, particularly through windows and window-wall joints. In Spain, in the middle of the last century, the use of vertical ventilation shafts in the wet rooms of dwellings became widespread, and it is currently the most common ventilation system in existing dwellings.

The need for airtightness control is a reality given its impact on buildings’ energy use and IAQ. For the past few years, this fact has resulted in energy performance regulations being established in many countries in Europe and North America. However, compliance proof is not always required, and on-site testing is often avoided. In this sense, predictive models have become useful in the decision-making process and to estimate input values in energy performance simulation tools.
