Optimum design of resistance and capacitance elements in modelling a sinusoidally excited building wall

Multi-layered walls design to optimize building-plant interaction

“…Analogous relations concerning a lumped-parameter wall with the scheme (19) can be obtained, as a peculiar case, from the relations in Section 3. By using the expressions of f 1 and f 2 , see Eq.…”

“…Other authors [19,20] describe the possibility to approximate the behaviour of building envelopes with lumpedparameter models. A structure made of a sequence of purely resistive and purely capacitive layers can approximate any distributed-parameter wall, either homogeneous or multilayered.…”

“…Obviously, the simplest interesting structure with the scheme (19) is the one characterized by n = 1; in this case the investigated wall results to be three-layered with the following scheme:…”

“…Also in this case it is convenient to use the lumpedparameter scheme (19), examining separately the walls characterized by various n. In this case every single layer in the scheme (19) is characterized by the matrixes 1 r s 0 1 1 0 sc s 1 according to whether it is a resistive or a capacitive one.…”

Dynamic Exergy Analysis for the Thermal Storage Optimization of the Building Envelope

“…One common problem is constituted by the summer performance of building constructions located in climates with hot days and relatively low nocturnal temperatures (like the Mediterranean). The role of thermal mass in lowering the cooling load of buildings is largely documented (e.g., in [5][6][7][8]), but not systematically and quantitatively acknowledged in current practice. The inner part of the envelope of modern buildings is generally not designed to absorb and release all of the internal and solar gains in a daily cycle, and air-conditioning is the usual solution to address the occurrences of overheating.…”
