Multifunctional PV facades, integrating thermal and electrical output, are being increasingly deployed in low energy buildings that exploit direct use of solar energy. Much existing research has focused on the integration of theses facades with the rest of the building, but detailed information on the performance of multifunctional facades is scarce, especially on the issue of control of both the electrical and thermal output. The experimental programme of work will utilise the advanced, large-scale solar simulator at Loughborough University to conduct detailed measurements of the airflow, heat transfer and electrical output in prototypical contructions over a wide range of operating conditions, focusing on the UK environment. A parallel modelling study will be carried out using a component-based approach: this will produce a set of advanced facade performance models which will represent a significant advance over the existing, closed-form models currently in use. Templates willbedeveloped which will allow the advanced component models produced to be synthesised into facade models in a range of contemporary simulation environments. Specific issues, such as the interaction of buoyancy-driven flow and hat transfer within the cavity, will be studied using an hierarchical approach based on a commercially-available CFD code
