“…The Scanning Electron Microscope (SEM) observations revealed that the reinforcing mechanism of wood fiber was a physical interaction. (Caruana et al 2014) provided an overview of testing methodologies for thermally improved hollow core concrete blocks by discussing testing methodologies for the load bearing as well as thermal characterization of hollow concrete blocks. (Caruana et al 2017) also investigated the thermal properties of a new building block aiming at improving its thermal properties without compromising their compressive strength, physical dimensions or manufacturing process.…”

Hollow-core concrete blocks constitute the main method of construction for vertical walls in Lebanon where almost all walls are masonry and use the same block shape. The detailed investigation of the main parameters involved in the heat transfer in these blocks is thus of great importance for analyzing and understanding them and providing recommendations for their improvement.This paper offers an experimental and numerical analysis of heat performance the Lebanese concrete hollow block. After validating the numerical model by comparing it to experimental results, a deep and detailed analysis is done for understanding the complexity of heat transfer phenomena inside the block. Then a parametric study is performed to understand the effect of various parameters on the overall thermal resistance of the block, these parameters include the concrete solid mixture, the cavities infill material, and the geometry configuration of the block.

“…Two field test cells were constructed in order to carry out in-situ thermal experiments. Figure 7 [17] and Figure 8 [16] below show the design of the setup of the two fully insulated test cells. The test wall models, with dimensions of 1.65 m by 1.90 m, were composed of 230 mm cementbased hollow-core block masonry having a north-facing orientation.…”

“…The experiment in Malta conducted by Caruana et al [109] studied the potential applicability of hollow-core concrete blocks with enhanced thermal properties. Three concrete mix designs, including different percentages of expandable clay, perlite and basalt were compared to a reference hollow-core concrete wall (comparative approach).…”

In the past decades the construction sector experienced the diffusion of a wide variety of complex building envelope components and passive elements and strategies, characterized by a dynamic response to the climatic parameters. Many of these components have been claimed to contribute to reducing building energy use and improving occupants' comfort. These kind of envelope elements need nevertheless to be tested under laboratory and real dynamic weather conditions in order to characterise, and possibly to model, their behaviour and their effectiveness both in terms of energy saving and indoor environmental quality. Both indoor laboratories and outdoor test cells have been developed in order to tackle the challenging issue of experimentally characterising innovative envelope elements. However, not always the experimental methodologies are fully and explicitly described in the available literature, and they are rarely compared to other types of experimental procedures. The aim of the present paper is to describe and review recent state of the art technologies for outdoor test cells. The paper starts with a short introduction on potentialities and limitations of outdoor facilities with respect to indoor laboratories and real buildings field tests, and it continues with a detailed classification and description of the most relevant outdoor test cells developed in recent years.
