3864 -- Frequency Response Analysis of Ground-Coupled Building Envelope Surfaces PDF

Presents response analysis of transfer functions relating indoor and outdoor temperatures (as the input signals) to heat flow through the building envelope (as the output signals). The frequency-domain solutions for foundation heat transfer are provided for both slab-on-grade floors and basements. The spectral analysis is then conducted using Bode and Nyquist diagrams to depict the variation of the magnitude and phase lag of the frequency-domain transfer functions. In particular the spectral sensitivity of building foundation response to periodic cycles, such as annual and diurnal cycles, is investigated.
