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. The 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. The 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. The 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. }}, author = {{Arztmann, Daniel}}, booktitle = {{Facade Tectonics : World Congress Los Angeles 2016 Conference Proceedings}}, editor = {{Noble, Douglas and Kensek, Karen and Das, Shreya }}, isbn = {{978-1-882352-43-2 }}, keywords = {{Curtain wall, energy efficiency, thermal break, condensation, physical testing, mockups}}, location = {{Los Angeles}}, publisher = {{Tectonic Press}}, title = {{{Shadow Boxes – Re-Engineered}}}, volume = {{2}}, year = {{2016}}, } @article{688, abstract = {{In this paper, we analyze the specific requirements of interacting with cyber-physical systems and propose a design approach that is driven by user needs and makes use of an expanded toolbox that contains state-of-the-art interaction technologies including Smart Glasses and Wearables.

It is important to efficiently advise the user to emulate the crucial features that define the good template. The proposed system (1) automatically mines the crucial features of any kind of motion from a set of motion features and (2) gives the user feedback about how to modify the motion through an intuitive interface. The crucial features are mined by feature sparsification through binary classification between the samples of good and other motions. An interface for motion coaching is designed to give feedback via different channels (e.g., visually, aurally), depending on the type of error. To use the total system, all the user must do is just move and then get feedback on the motion.

Instead, it is argued, that the trade-off is not of fundamental nature, but caused by neglecting elementary aspects in the design process. In order to verify this line of argument, a novel interface concept for mediating socio-emotional awareness information is presented. To verify the validity of the conceptual approach, several evaluations were conducted.
