text: "This paper provides information about an in-house research project for shadow
box design. During this research project, several mockups with sensors for heat
and relative humidity were produced and tested under two different laboratory
conditions: one with artificial sunlight and one in an outdoor temperate climate.
\ \r\nThe outdoor test provided information about temperature changes in the shadow
box due to air infiltration and exfiltration. Further, it also provided information
about the conservation of solar energy in the air cavity behind the spandrel glass
and adjacent materials. Temperature sensors on the interior surfaces of the façade
produced data that was used to draw conclusions about the heat flow from inside
the shadow box to the interior ambient air via the façade profiles. It was also
used to develop a two-dimensional simulation tool to show heat development and
heat flow in the shadow box. \r\nThe test under laboratory conditions with artificial
sunlight showed that the correct choice of glass type and color of the opaque
back layer highly influences heat development in the shadow box cavity. The test
results also illustrate that the size of ventilation openings and the depth of
the air layer only slightly influence heat built-up in this cavity. \r\nThe shadow
box is a very complex system that should be designed and manufactured so as not
to have a detrimental effect on the thermal performance of the facade. To maintain
precise and consistent reproduction and to improve the thermal performance, a
new PVC shadow box profile was developed. PVC is a poor thermal conductor and,
therefore, the heat flow from the shadow box construction into the interior becomes
interrupted, consequently improving the heat transfer coefficients of the façade
and the panel construction. Furthermore, the PVC profile has been designed as
a four sided mitered and sealed frame insert to enable easy attachment of the
opaque back layer, thus creating a weather tight assembly within the curtain wall
day light opening. "
