Prefabricated concrete systems of different complexity (from ordinary blocks to sophisticated insulated wall panels) and end-use will be installed in different climatic conditions for demonstration purposes. Their environmental performance will be validated through dedicated LCAs. Pre-cast products developed in this project are intended for new construction as well as for deep retrofitting, as for example the renovation of commercial buildings or social housing construction.
The thermal insulation is scheduled to be tested as well as indoor and surface temperature and the heat flow through the panels. Additional future tests are expected to be held after installation. During the acclimation periods in varying seasons and weather conditions, the power consumption for heating and cooling will be measured. These measurements will be compared with their standards cement-based mock-ups.
PANELS INSTALLATION AT KUBIK DEMO-SITE
KUBIK demo-site in Derio enables the evaluation of energy performance, taking into account the holistic interaction of the constructive solution for the envelope, the intelligent HVAC and lighting management, jointly with the supply from non renewable and renewable energy sources. The main distinctive feature of KUBIK is its capacity to create realistic scenarios with different uses. Prototypes at the KUBIK demo-site consist of four panels (1.52 m /width/ x 3.56 m /height/ x 25 cm /thickness/).

BUILDING MOCK-UPS AT ACCIONA DEMO-PARK
Four reference buildings were built at ACCIONA Demo-park in San Sebastian de los Reyes during September 2017. Each demo-building consists of four panels (one for each wall), roof made of polyurethane panel between two metal layers, and steel structure. The internal measures are 2.95 m x 2.35 m x 2.40 m (high), the external measures are 3.40 m x 2.80 m x 2.45 m (high). One reference building was made of conventional construction material, such as OPC concrete, and other three buildings were made of BYF special cement, each one developed by different cement producers (HEIDELBERG CEMENT, LAFARGE and VICAT).
After the completion of the construction, acoustic tests were performed. ACCIONA will also validate the durability, energy efficiency, and thermal comfort during the service life of the BYF facade under real conditions. All the parameters will be measured, validated, and compared with the ones obtained in the reference buildings made of conventional materials.
