ACTIVE INTERFACES. Holistic design strategies for renovation projects with buildingintegrated photovoltaics (BIPV): case study from the 1900s in Neuchâtel (Switzerland).

Sophie Lufkin, Sergi Aguacil Moreno

As the majority of buildings that will exist in 2050 are already built, with many of them having a low level of energy performance, urban renewal processes play an essential role towards the sustainable development of cities. In this context, BIPV systems ...

Insulation effect on thermal stability of Coated Conductors wires in liquid nitrogen

Bertrand Dutoit

Superconducting wires are not perfectly homogeneous in term of critical current as well as stabilization. In resistive fault current limiter applications this could lead to hot spots if the fault current is only slightly above the nominal current of the de ...

Sensitivity analysis of visual and thermal parameters for energy savings: combining illuminance and temperature set-points for possible trade-offs

Marilyne Andersen, Jan Wienold, Joshua Pereira, Giorgia Chinazzo, Mathieu Plourde

This study presents a methodology for evaluating the effects of simultaneous temperature and illuminance set-point variations on energy consumption. Different illuminance levels are achieved with an innovative dynamic shading control algorithm that allows ...

Large and reversible shape changes as a strategy for structural adaptation

Ian Smith, Gennaro Senatore, Arka Prabhata Reksowardojo

Adaptive structures are sensed and actuated to perform tasks such as modifying their internal load-path in response to external actions to maintain optimal performance. Shape control and load-path redirection have been investigated to counteract the effect ...

OESPG: Computational Framework for Multidimensional Analysis of Occupant Energy Use Data in Commercial Buildings

Andrew James Sonta

Commercial buildings account for much of the energy use both in the United States and globally. The role of occupant behavior within the physical building has been found to be an important factor in the overall energy use profile of commercial buildings. R ...
