Thermoelectric Materials In Exterior Walls: Experimental Study On Using Smart Facades For Heating And Cooling In High-Performance Buildings, Ajla Aksamija, Zlatan Aksamija, Christopher H. Counihan, Dylan Brown, Meenakshi Upadhyaya Dec 2017

Thermoelectric Materials In Exterior Walls: Experimental Study On Using Smart Facades For Heating And Cooling In High-Performance Buildings, Ajla Aksamija, Zlatan Aksamija, Christopher H. Counihan, Dylan Brown, Meenakshi Upadhyaya

Ajla Aksamija

This article discusses design, prototype development and an experimental study of facade-integrated thermoelectric (TE) materials. TEs are smart materials that have the ability to produce a temperature gradient when electricity is applied, exploiting the Peltier effect, or to generate a voltage when exposed to a temperature gradient, utilizing the Seebeck effect. TEs can be used for heating, cooling, or power generation. In this research, heating and cooling potentials of these novel systems were explored. Initially, two low fidelity prototypes were designed and constructed, where one prototype was used to study integration of TE modules (TEM) as stand-alone elements in the ...

A Cost-Effective Integral Bridge System With Precast Concrete I-Girders For Seismic Application, Justin R. Vander Werff, Rick Snyder, Sri Sritharan, Jay Holombo

Faculty Work Comprehensive List

To promote accelerated bridge construction in seismic regions, a large-scale experimental investigation was conducted to examine the seismic sufficiency of precast concrete I-girders in integral bridge super-structures. Such structures are not frequently used in high seismic regions due to lack of design guides and overly conservative design approaches. A half-scale,17.8 m (58.5 ft) long test unit modeling a portion of a prototype bridge incorporating a concrete column, ten I-shaped precast concrete girders, and an inverted-tee concrete cap beam was used to experimentally verify that precast concrete members employing accelerated construction techniques can be used in integral super-structures ...


Development Of A Field Procedure To Measure The Airtightness Of Wall Construction Elements Of Houses, Grenville K. Yuill, David Yuill Dec 1997

Development Of A Field Procedure To Measure The Airtightness Of Wall Construction Elements Of Houses, Grenville K. Yuill, David Yuill

David Yuill

Whole-house tests were developed to compare the airflow resistance of several different materials used to seal the walls of a house at the outer surface. These airflow resistances were measured in field installations and include the effects of interactions with adjacent materials and assemblies. The materials tested were housewrap fiberboard and foam sheathings, extruded polystyrene foam sheathing with the edges taped, extruded polystyrene sheathing with the edges untaped, and caulking and foaming the inside of the wall cavity. The comparisons were between different wall materials installed in sequence in the same house. In this way, any inherent differences in house ...
