“ENERGY in BUILDINGS” is an International Conference that will take place for the seventh consecutive year. It brings together Engineers, Architects, Stakeholders, Academia and Professionals of different disciplines that contribute and advance the state of art of the built environment. The Conference will host accepted papers and posters as well as presentations and workshops of invited speakers. There is no conference registration fee. The official language of the Conference is English.

This year the Conference will host the thematic TESSE2B conference in the field of energy storage targeted to Energy Efficient Buildings. This thematic event will present and discuss current innovation in the Energy Storage field targeted to Energy Efficiency & Built Environment, focusing on integrated solutions for residential building energy storage by solar and geothermal resources. Results will be presented from the ongoing European project, as well as results from other projects in the area of energy storage (more).

The objective of this session is to provide an opportunity to exchange views on key areas of lighting, to present progress in technology and to discuss current and future challenges and perspectives. Areas of interest include, but are not limited to: Lighting technology, lighting sources, …
