The application of a wide range of nano-enabled materials will make available a customizable element design for each building architectural style and enhancing it with powerful renewable energy generation features, optimizing their efficiency by maintaining the optimum operational parameters, modernizing the envelope, and increasing its economic and aesthetic value. In this framework, the methodology for delivering decision support services for evaluating alternative hybrid energy storage schemes in building materials is presented. Multiphysics and multiscale materials modelling are presented for evaluating the thermal properties of innovative composites using a high sorptive industrial mineral carrying PCMs. The goal is to utilize inorganic and low cost highly porous expanded perlite for absorbing paraffin and encapsulating it in a thin film geopolymer coating. The paraffin provides a way for exploiting the latent heat enhancing the thermal mass of the building shell able to absorb or release thermal energy, behaving as a thermal capacitor. In this study both sorption capacity and penetration absorbency models are presented to estimate the inter and intra-particle sorption capacity, able to evaluate the volume of paraffin that can be absorbed translated to heat storage capacity. The roadmap is to adapt models to simulators for defining both building’s retrofit and new constructions.


Chrysa Politi holds a Diploma in Mechanical Engineering from the School of Mechanical Engineering of the National Technical University in Athens. While holding a B.Sc. in Mechanical Engineering and an M.Sc. specialization in energy and sustainability engineering, her PhD research is focused on buildings energy optimisation by incorporating form-stable phase change materials, with the utilisation of deep learning algorithms. Her competencies include analytical thinking, teamwork, results-orientation, communication and eagerness to take on challenging projects.

Chrysa is an active member of the Technical Chamber of Greece (TEE) and a Certified Lead Auditor in ISO 14001:2015, ISO 9001:2015 and Customer Service by TÜV HELLAS – TÜV NORD.

Since 2018, she is a Junior Researcher at the Raw Materials Exploitation & Sustainable Energy Solutions Research Group Laboratory of Metallurgy, School of Mining and Metallurgical Engineering at the same university. She has participated in EU funded H2020 research and innovation projects including SABINA and PVADAPT related to increasing RES penetration by exploiting synergies between electrical flexibility and the thermal inertia of buildings as well as combining passive and sustainable components to produce prefabricated BIPV modules. In addition, she participated in CEF PSA i.e. FPC4Consumers and IDACS dedicated to comparing fuel prices under a common unit and collecting data of recharging/refueling points for alternative fuels. Currently, she is involved in several projects (Frontsh1p, Mozart, SEC4TD) related to all the stages of Life Cycle Assessment, including Environmental and Social Impacts.

Keen researcher, Chrysa has attended several international professional and scholarly meetings among which is the Summer School TOP STARS 2019 hosted by the Department of Industrial Engineering University of Trento in focusing on EIT Raw Materials and supported by the EIT Regional Innovation Scheme (EIT RIS).
