Rijksmuseum Amsterdam

Abstract
In the framework of the refurbishment process of the Rijksmuseum Amsterdam,
it is intended to provide an adequate internal insulation of the exterior facades,
which increases indoor climate quality, ensures hygric durability and reduces
heat losses. This contribution shows the suitability of a capillary active internal
insulation in order to distribute the interstitial condensation and the penetrated
rain water. Foam glass prevents the drying potentials and leads to the destruction
of the brick wall.
1 Introduction
This expertise investigates the hygrothermal behaviour of two different internal
insulation options: cellular glass and calcium silicate. Of course, as a reference
case, differences to the behaviour of the current construction are also analysed.
The façade of the Rijksmuseum (fig. 1) is worth preserving and can not be
covered with an outside insulation material.
All important results are summarized and recommended one insulation
system with a specified thickness of the insulation layer. The analysis is carried
out with the simulation software DELPHIN [1], which has been developed at the
Institute for Building Climatology for research purposes. With this software tool
the coupled heat and moisture transfer through porous media with known
material functions can be calculated.
During the simulation, the construction is exposed to hygrothermal loads.
Unsteady influences i.e. the annual course of temperature and relative humidity,
the impact of driving rain, short and long wave radiation are taken into account.
Air and salt transport will not be considered.
