Abstract: A transient threedimensional numerical solution is developed to analyze the thermal performance of thermoactive foundations used to heat and cool commercial buildings. Using laboratory testing data, the numerical solution ...

Abstract: The application of thermo-active foundation (TAF) systems to heat and cool residential buildings is evaluated in this paper. First, a transient three-dimensional finite difference numerical model is developed for the ...

Abstract: This paper investigates the impact of thermal interactions between heat exchangers integrated within building foundation piles to meet space heating and cooling needs of buildings. Specifically, a three-dimensional transient ...
