Parametrising a transparent insulation wall system in a simulation program - studies for a convective system

Abstract

A characterisation method for TI wall systems was developed. Existing numerical building simulation programs can easily be extended by using this method e.g. as a subroutine. Any given transparent insulation system is treated as a "black box" system mounted on a house wall. In a similar way to TI materials, it can be described by a systematic energy gain factor gsubsys and a systematic u-value usubsys. A ventilated TI wall system was parameterised and thus included in a building simulation program. The results show that the complex convective heat transfer can be described with the parameters introduced above. Here gsubsys as well as usubsys are dependent on the wall temperature, the ambient temperature and the solar irradiation
