Numerical estimation of time lags and decrement factors for wall complexes including Multilayer Thermal Insulation, in two different climatic zones

The impact of evaporation from porous tile on roof thermal performance: A case study of Guangzhou’s climatic conditions

“…6, the hourly weather data for 21 July in Guangzhou, obtained using Eqs. (7)(8)(9)(10)(11)(12), were used for the following roof thermal performance calculation. The indoor air temperature was set to a constant value of 26 • C. Other boundary conditions, including the surface solar absorptivity, thermal resistance of each layer, and combined heat transfer coefficients at the external and internal surfaces, are listed in Subsection 2.3.…”

“…Measures that use the intrinsic physical mechanisms of a building (e.g. radiation [5], convection [6], heat conduction [7], and phase change [8]) to limit, increase, or convert the energy exchanged between the building and its surrounding environment are passive techniques. In recent years, among the effective strategies addressing climate change and environmental pollution, passive techniques have increasingly attracted the attention of researchers [9].…”

Thermal delay provided by floors containing layers that incorporate expanded cork granule waste

“…Their paper proposes a finite-difference solution of a system of coupled differential equations describing the transient heat transfer and energy balance in buildings; this is used to calculate the time delay for a wide range of climate conditions and a variety of fully-insulated and noninsulated buildings. Few years later, Antonopoulos and Koronaki [12] presented a procedure for envelope is important to improve the prediction of the dynamic thermal behaviour of buildings in the design phase. Kravvaritis et al [15] developed a 'thermal delay method' based on the 'Thistory' method used to measure the thermal properties of phase change materials (PCMs).…”

“…In fact, over the last few years thermal capacity is increasingly cited as an important saving energy aspect that also improves a building's comfort levels ( [8]- [12]). Greater thermal capacity enables indoor thermal comfort to be achieved using less energy for climate control.…”

“…Multilayer systems composed of different materials seem to be a rational choice for use in the building envelope, particularly when thermally and acoustically optimized solutions are required ( [12], [16]- [17]). Additionally, the current environmental context demands energy conservation along with the use of low impact materials with high technical performance [19].…”
