Dear TRNSYS specialists: How can I simulate a thermal storage wall and a thermal bed floor in an environmentally symbiotic housing? I am now studying on the effect of the passive solar system in an environmentally symbiotic housing. As described in figure 1 and 2 of the attached file "Figure.ppt", the floor of the environmentally symbiotic housing consist partly of high thermal storage concrete which is nearest to the south window. The thermal storage concrete bed plays an important role in winter by storaging heat when radiated by sun in daytime and releasing the heat in night. And three thermal storage walls (Figure 1, painted in yellow) are also inside the room . Do you know how to cope with it? It is said in the "TRNSYS manual" that internal walls are assumed to affect building response only as the result of their mass. Is it correct if I input the high thermal storage wall as an internal wall in PREBID. And how to simulate the effect of the high thermal storage floor nearest to the south window? To describe it as a Wall between zones and define the ABS-Front for the floor as 0.9 so as to weight the solar absorptance of the different surfaces? Or cope with it by adding part of the thermal capacity of the thermal storage wall into the capacitance of house air? It seems that TYPE 10 (Rock Bed Thermal Storage) and TYPE 36 (Thermal Storage Wall) could not be used to simulate it this time. Does anybody know how to deal with this problem? I am eagly looking forward to your answer. With best regards, Yours sincerely Bo, ZHOU 5/16
