IsZEB HygroThermal
IsZEB HygroThermal is an online platform, an interactive intelligent system, that models the thermal behavior of building elements, considering the effect of moisture in the individual materials (hygrothermal behavior). By thoroughly analyzing existing tools and methodologies, as well as new specifications, IsZEB HygroThermal fully aligns with current legislation, while introducing new concepts and technologies, offering a more techno-economic holistic approach.
Key Features: The software consists of a support system (backend) and an interactive online platform (frontend) for user engagement.
The user has the option to choose data and properties of building materials, either through an existing material library or by entering the properties of materials of their choice. Building elements are defined as different layers of building materials. The platform enables parametric studies of various building elements, with customizable physical and numerical parameters.
The platform offers the possibility to implement three different numerical approaches:
- Steady-state approach, with constant temperature and humidity conditions at the boundary.
- Time-varying approach, considering temporal changes.
- Periodic approach, based on the prevailing external environmental conditions.
After appropriate calculations, representative results and graphs are presented for important parameters of the problem, such as space/time temperature and humidity profiles, heat flow to and from the building element, key thermal indicators, as well as an estimation of cost and energy savings.
Finally, the tool offers the ability to connect either to thermal cameras or moisture meters, allowing the user to input real-time actual conditions as boundary conditions. This feature makes the tool highly innovative, providing users with the ability to conduct on-site measurements and assessments of the real performance of thermal insulation materials.
The research projects IsZEB Certify, IsZEB Charge and IsZEB Assist AR were created in the framework of the Program "Collaborative Formations for the promotion of innovation in local entrepreneurship" of the OP. Of the Region of Central Macedonia, NSRF 2014-2020 with the co-financing of Greece and the European Union.
