Demo Sites

The BIOBUILD concept, with the direct integration of bioPCM in flooring and wall structures, aims to reduce up to 20% of energy demand in buildings located in different climates in Southern and Northern Europe. 

Two demonstration sites are selected to test and evaluate the BIOBUILD concept, including different building types and climates in Spain and Sweden. One house serves as a baseline and is compared to another house incorporating the novel BIOBUILD materials. The selected model “Orust” of EHUS production, is a one-story prefabricated house with an internal floor area of 35 m2.

Both houses are furnished with integrated heating, ventilation, and air conditioning (HVAC) systems, ensuring thermal comfort by fulfilling the requirements for both space heating and cooling. These constructions are designed for practical use, serving as either offices or residential areas, considering the installation and impact of all essential services and facilities.

Prototype demonstrations and tests will be harmonised in advance to facilitate result comparison and utilise advanced models to gain maximum data and information, identifying the best novel products. Strict procedures will be followed for an independent evaluation of key performance metrics in terms of energy efficiency impacts, thermal comfort benefits, overall life cycle environmental impacts, and life cycle cost metrics. These activities will run concurrently with technical developments, enabling interactive evaluation and improvement of products and processes.

In BIOBUILD, the project will define significant refence scenarios and conduct simulations to model the thermal dynamics and temperature variations within buildings. These simulations will use numerical models with sub-hourly time steps resulting in energy consumption figures for heating and cooling demands. The project will assess comfort levels throughout a full year.

Currently, there is an ongoing study examining the use of bio-composites containing bioPCM in flooring and wall boards of a 1m3 cube model exposed to real outdoor conditions. A control model without bioPCM is also being assessed, in order to investigate the effect of using energy smart bio-composites in saving energy when maintaining a constant internal temperature. Preliminary results indicate that the cube incorporating smart bio composite consumes less electricity than the control cube without bioPCM while ensuring a fixed internal even amidst fluctuations in outdoor temperature changes.
