“…Currently, many studies have been performed on the use of natural building materials, since these materials have characteristics of high sustainability [2][3][4][5][6][7][8][9]. In particular, for straw, useful suggestions have been taken by the following studies [10][11][12][13].…”

Abstract:Straw is an inevitable product of cereal production and is available in huge quantities in the world. In order to use straw-bales as a building material, the characteristic values of the thermal performances should be determined. To not lose the benefits of the cheapness and sustainability of the material, the characteristics must be determined with simple and inexpensive means and procedures. This research aims to implement tools and methods focused at the determination of the thermal properties of straw-bales. For this study, the guidelines dictated by ASTM and ISO were followed. A measurement system consisting of a Metering Chamber (MC) was realized. The MC was placed inside a Climate Chamber (CC). During the test, a known quantity of energy is introduced inside MC. When the steady-state is reached, all the energy put into MC passes through its walls in CC, where it is absorbed by the air-conditioner. A series of thermopiles detect the temperature of the surfaces of the measurement system and of the specimen. Determining the amount of energy transmitted by the various parts of MC and by the specimen, it is possible to apply Fourier's law to calculate the thermal conductivity of the specimen.

Thermal performance of hemp concrete and hemp wool such as ecological insulation was evaluated for the city of Meknes in Morocco, in comparison with polystyrene which is an organic insulation material. The study was done in three sections. First, a thermo-physical properties characterization was done using the EI700 device. Then, the study was done on a concrete wall subjected to periodic outdoor conditions. The three insulation materials are used and the effects of thickness, location and partitioning on the time lag and decrement factor were investigated. Finally, heating and cooling loads of a whole building with the use of six different walls configurations are calculated using TRNSYS software. Throughout the whole study, results show that hemp wool presented the best thermal performance, and the evaluation of its use such us an insulation material in Morocco and especially in Meknes was investigated.

“…Even if the building research community has been always using building performance simulation tools [22][23][24][25][26][27][28][29], this kind of research is not coupled with the architectural design process at early design stages. As it is well-argued elsewhere, there are many reasons for this delay, starting from the difficulty of using complex sophisticated simulation tools to describe complex physical phenomena [26,28,[30][31][32], the augmented calculation time needed for such operations, the uncertainty in the results and the general impression that the designer is restricted by the limitations of the tools [33,34]. Architectural discourse has always included a reflection on providing a high quality and comfortable interior environment via an equilibrated architectural project, albeit the use of computer-aided building energy simulation software in the decision-making process for building form optimization at early conceptual stages is limited.…”
