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

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

Zlatan Aksamija

This article discusses the design, prototype development and an experimental study of facade-integrated thermoelectric (TE) materials. TEs are semiconductors 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 applications of these novel systems were explored. Initially, we designed and constructed two prototypes, where one prototype was used to study integration of TE modules (TEM) as stand-alone elements in the facade, and …

The Impact Of Roof Pitch And Ceiling Insulation On Cooling Load Of Naturally-Ventilated Attics, Shimin Wang, Zhigang Shen, Linxia Gu Jan 2012

The Impact Of Roof Pitch And Ceiling Insulation On Cooling Load Of Naturally-Ventilated Attics, Shimin Wang, Zhigang Shen, Linxia Gu

Durham School of Architectural Engineering and Construction: Faculty Publications

A 2D unsteady computational fluid dynamics (CFD) model is employed to simulate buoyancy-driven turbulent ventilation in attics with different pitch values and ceiling insulation levels under summer conditions. The impacts of roof pitch and ceiling insulation on the cooling load of gable-roof residential buildings are investigated based on the simulation of turbulent air flow and natural convection heat transfer in attic spaces with roof pitches from 3/12 to 18/12 combined with ceiling insulation levels from R-1.2 to R-40. The modeling results show that the air flows in the attics are steady and exhibit a general streamline pattern that is qualitatively …

Passive Solar Design, David A. Bainbridge Jan 2011

Passive Solar Design, David A. Bainbridge

David A Bainbridge

Passive solar architecture can provide heating, cooling, ventilation and daylighting by using the sun and microclimate resources. Building energy consumption can be cut 80-90% at no increase in building cost by using integrated design principles.
