Numerical Simulation of an Integrated Solar Louvre Collector System

External louvres are increasingly used to provide solar protection for building glazed surfaces. This work concerns the modification of existing louvre designs to integrate a solar collector in the shading device. A numerical model for the integrated solar collector was developed, and collector efficiency was quantified. Thermal performance for a water heating system was obtained, on a month-to-month basis, under the climatic conditions of Portugal.
