Task 2 : Energy performance assessment
This task is the most interdisciplinary, as it requires consideration of the ground response, as well as all factors affecting the building energy performance, such as climate, building typology, surroundings and use.
To successfully integrate thermoactive structures into the portfolio of possible solutions available to energy engineers, it is crucial to fully characterise the thermal energy profiles of different types of buildings in their relationship with the supporting elements, which are to be thermally activated.
It is also of paramount importance to identify those scenarios where an optimal relation between the building’s demands and ground capacities can be established, taking into account state of the art solutions and costs, in order to facilitate the large scale deployment of thermoactive geostructures.
Numerical modelling of different scenarios with varying soil conditions, building typologies, type of thermoactive structure and climate will be performed, with the aim of identifying the most favourable conditions for the use of this technology.
Finally, a database with several examples of instrumented thermoactive geostructures in service will be assembled to illustrate thermal design principles. Thermoactive geostructures can provide an alternative and cost-effective solution to improve energy performance of buildings and it is important in this task to outline the methodology for successful applications.
