Information

This model is a verification test for model IDEAS.Buildings.Components.BaseClasses.RadiativeHeatTransfer.ZoneLwDistribution.

Three different approaches are used to model a black cube with face surface areas of 4 m2. The emissivity of each surface is one. The first surface has a time-varying temperature, whereas the five others have a fixed temperature. In intHeaRad the five other surfaces are lumped into one surface. In zonLwDist an equivalent radiant star point is used. In zonLwVieFac view factors are computed. All three approaches should give exactly the same result for the given geometry and emissivities.
