PERFORMANCE INTEGRATED AM FACADES: EXPERIMENTAL TESTING OF 3D PRINTED STRUCTURES FOR THERMAL INSULATION
Facades are the main interface controlling the flow of energy and matter in buildings and are required to be efficient integrated components. Digital fabrication offers unseen potentials for geometrical freedom and performance integration, which are relevant for application in the building envelope.
Keywords: Facades, Additive Manufacturing, Building physics, Thermal insulation, Physical experiments
Within the collaborative NCCR project "Integrative Facade Systems" we are investigating the thermal insulation potential of 3DP porous structures for application in building facades. This study will be a contribution to this on-going research.

The main objectives of this study are:
1) Finalise the experimental set-up for thermal conductivity measurements. The hot-box apparatus includes a climatic chamber equipped with thermocouples, heat-flux sensors and data loggers.
2) Perform measurements on a set 3DP samples to:
a. Determine the effective thermal properties of different geometrical configurations
b. Identify the influence of geometrical parameters (air cavity size, arrangement, porosity) and retrieve design guidelines
_Optional:_
3) Validate the experimental results using computational tools (multiphysics FEA simulations)
