Building Information Modeling for Energy Retrofitting

In the era of strong IT development, superior processing of information is a desideratum in any business. Used in modeling and simulation, information has better capitalization, having a cognitive role; introduced in various algorithms and models can generate knowledge and wisdom. The processing of information is realized within the information systems (IS). A sub-domain of the energy sector that has developed in recent years is energy retrofitting, seen as a border subdomain, including specific elements from building construction and the energy field, for building analysis and construction process to achieve much larger energy savings. The development of retrofitting can be organized, through using BEM (Building Energy Model) and Building Information Modeling (BIM) models.
