Abstract

Research in the field of passive solar energy has been performed at the JRC for over ten years. Four testcells are presently available for experimental assessment of thermal parameters under real weather conditions. The JRC Ispra is one of the 12 European outdoor passive solar test sites and takes part in several European projects. The work at the JRC solar test site has concentrated on the development of reliable parameter identification methods for standardisation and reference methods. As well as the two methods based on a lumped parameter model and a continuous time model, developed under the PASSYS project, modal models and armax models are used. Understanding the heat gains from solar radiation is an important issue in solar control and therefore in the application of passive heating or cooling. The solar factor of an opaque building component is not always considered important. The influence of climate is also significant. The solar aperture is one of the steady state parameters of interest for the energy distribution in buildings. It is well-known from theoretical analysis that it is influenced by the season and the position of the building of interest. However, experimental work in this direction is mainly performed on windows and indoor test procedures. Results from outdoor experiments are reported.
