“…Continuing this line, the researchers proposed a process assumption-based design method [62], which was an interdependent but distinguishable two-step approach, for the process design of a building's thermally autonomous and homeostatic existence. This two-step approach was demonstrated in two recent papers [62,63].…”

“…The first "architectural" step [62] treated a building's thermal performance, not for sizing HVAC system, but for determining a building's architectural requirement with the objective of building thermal autonomy within an acceptable operative temperature range. The condition of maxΔT in r2 K was selected as a constraint for a building with a certain amount of internal (including solar) gain subject to a given ambient temperature amplitude.…”

“…The circulating water in the pipe-embedded building envelope functions as a heat sink or heat source to discharge or charge the pipe-embedded building envelope actively, distinguished from passive application forms (e.g. a high-mass solid building envelope [2,3]). Passive applications utilize the thermal storage of building mass to shift or reduce the peak cooling or heating load in the forms of passive heat exchange.…”

a b s t r a c tActive pipe-embedded building envelope is a new kind of external building wall or roof which usually has pipes embedded in it to let water circulate in these pipes for heat transfer. This structure may effectively intercept the heat/coolth from the ambient environment to indoor space and provide extra space conditioning for the indoor space. Frequency-domain finite-difference (FDFD) model can predict the frequency thermal response of active pipe-embedded building envelope directly and provide some important guidelines for system control and system sizing. This paper presents the experimental validation of this model in time domain by using Fourier series analysis. An experiment test rig was developed for the thermal response measurements of the pipe-embedded building envelope under pre-defined conditions. First, the measured time series of surface temperatures are transformed into complex Fourier series by using Discrete Fourier Transform and applied into the FDFD model as the boundary condition for calculation. Then, the calculated frequency thermal responses by FDFD model can be easily transformed into time series by using Inverse Discrete Fourier Transform. Finally, the time-domain thermal responses of FDFD model are obtained. The results show that the calculated time-domain thermal responses of the active pipe-embedded building envelope by using FDFD model agree well with the experimental measurements.
