As of now, in the EU, all new buildings will have to comply with requirements for nearly zero energy (nZEB). Portugal defines limits maximum useful needs heating and primary establishes that 50% must be covered by local renewable sources, based on dwellings’ nominal condition use. However, actual use is different. Thus, a simulation tool used assess thermal comfort different conditions dwelling...

Abstract Reaching nearly Zero Energy Building (nZEB) standards through retrofit can be achieved by adopting controlled procedures and assessment tools. The main issue of operational energy consumption before after refurbishment should calculated with reliable predictive models to support investment payback time evaluations. For that purpose, dynamic simulation reduce the performance gap between...

The research explores the potential of digital-twin-based methods and approaches aimed at achieving an intelligent optimization automation system for energy management a residential district through use three-dimensional data model integrated with Internet Things, artificial intelligence machine learning. case study is focused on Rinascimento III in Rome, area consisting 16 eight-floor building...

The emerging and improvement of smart grids, net–zero energy buildings, and advanced building energy demand response technologies continuously drive the needs for better building control and operation strategies and building energy simulation testbeds. However, current building operation strategies and simulation testbeds are all developed assuming that buildings do not share energy resources. ...
