“…The research in the simulator was carried out simultaneously for three types of CAW differing in the masonry material used to make the masonry wall: ordinary concrete on natural aggregate (ρ=2200 kg/m 3 ), aerated concrete (ρ=750 kg/m 3 ) and sand-lime blocks (ρ=1600 kg/m 3 ). Simultaneous measurement of the tested parameters in three types of partitions provided similar boundary conditions for the experiment.…”

“…The efficiency with which TW uses the transferred heat may vary depending on thermophysical parameters and climatic conditions. It is mostly determined with the use of numerical models that are based either on the finite element method FEM or finite difference method DEM [1][2][3]. In the papers [4,5], the calculation of the efficiency of various types of walls was carried out in field conditions either with the use of speciallyprepared research chambers or experimental houses [6].…”

Passive systems are becoming increasingly popular among designers, which is reflected in their frequent use in the construction of modern buildings. The prevailing material in façade design is glass which enables i.a. photothermal conversion of solar energy either in the so-called direct systems or in one of a number of the collector-and-storage Trombe wall variants. In order to estimate how the aforementioned passive solutions affect the energy balance of a building, the efficiency of such solutions needs to be determined first. This paper presents the research proposal that would use a simple-structure laboratory simulator. The proposed method is based on the analogy of supplying heat into the TW itself with an internal heat source. In order to simulate the absorption of solar radiation that takes place in the absorber, the heat was produced by the heating cable embedded in such an absorber. The results of tests carried out according to one of the Design of Experiments (DOE) methods enabled the development of an empirical model showing the operation efficiency of the originally modified Trombe wall.

“…In recent years, the research in the building sector has been focused on the study and the identification of appropriate natural materials to use in envelope assembling to increase the sustainability level, in terms of energy consumption [1], limitation and reduction of artificially manufactured goods [2]. Indeed, buildings are a large source of environmental pollution due to the energy needs, extraction, processing, transport, assembly and successive disposal of the involved materials [3,4]. The "bio-architecture" approach allows for rational exploitation of natural resources, reducing artificial raw materials and wastes, and promoting the use of natural materials to be recycled after the disposal phase [5,6].…”

A Novel Bio-Architectural Temporary Housing Designed for the Mediterranean Area: Theoretical and Experimental Analysis

et al. 2022

Energy performances of an innovative Temporary Housing Unit (THU), made of natural materials and developed for the Mediterranean area, were determined. Cork panels limit winter transmission losses, whereas bio-PCMs were applied to reduce cooling needs properly. Assuming a split system for air-conditioning purposes, simulations in EnergyPlus allowed for identifying the optimal configuration that minimizes the annual electric demand. Bio-PCM melting temperatures, locations inside the external walls and the PCM quantities were varied. An ideal melting temperature of 23 °C was identified, whereas a double PCM layer uniformly distributed in the external walls is recommended, mainly for the limitation of the cooling demands. Negligible differences in electric requirements have been observed between the continuous and the scheduled functioning of the split system. A PV generator installed on the available roof surface allows for covering the electric demands satisfactorily. Experimental tests carried out in a climatic chamber have allowed for determining the dynamic thermal performance of the optimized panel by considering variable external conditions. Results show how the considered PCM in summer is able to delay and attenuate the indoor air temperature peaks considerably, confirming the crucial role of bio-PCM to reduce cooling demands, in line with the simulation results.

“…A large thermal capacity of building partitions can be obtained by building them from materials with a high specific heat. In the works [1][2] the functioning of collectoraccumulation walls was presented, whose massive storage wall stabilizes daily changes in the air temperature inside the adjacent room.…”

This article presents the possibilities of using phase change materials for the modernization of transparent partitions and elements functioning with them. The author draws attention to the possibility of reducing the energy costs of the building, by increasing the thermal capacity of the internal window blinds. The article draws attention to many factors related both to the properties of PCMs themselves, the place of application and climatic conditions that may affect the effectiveness of the entire solution. To assess the energy efficiency of the abovementioned shutter, field tests were carried out in an isothermal test chamber. The article presents the results of the conducted research, showing the advantages and disadvantages of the considered solution. A large number of scientific papers, in which the possibilities of using phase change materials for the modernization of transparent partitions are presented, apply only to the modernization of glazing. In this context, this work presents a different approach to the issues of using phase change materials in construction.
