Thermo-optical properties of construction materials are important factors while designing a building. Human comfort and environmental issues are the main reasons inciting researchers to work in this field. For instance, the thermal conductivity coefficient, the optical reflectance, the optical transmittance and the optical absorbance of materials are frequently measured properties in civil engineering. Currently, each of these physical coefficients is measured separately by various devices. A new experimental device is therefore designed to measure these properties in a single unit. The data presented in the article consists of the experimentation process of designing a new type device. This paper includes data for calibration, measurements and validation for the elements of the new device. This data has been collected in the laboratory and is made available for reproducibility and improvement research in the field of thermo-optical properties of construction materials. This data article is related to the original research article of Fakra et al. denoted “A new simple experimental device for measuring the thermo-optical properties of translucent construction materials.” [1] .

Electricity needs are growing rapidly in developing countries. Some governments are encouraging the integration of renewable energy into the electrical grid to deal with the environmental issues, depletion issues, and pollution issues from current conventional power generation systems.Therefore, a reliable tool is needed to manage this energy mix. A tool based on two new different strategies is proposed for the management of smart grids. A comparison with the HOMER software was carried out to ensure the reliability of the proposed tool to simulate the management of this energy mix. Furthermore, this tool is capable of simulating the management of energy-mix flows from a building to a country. Users can visualize the simulated environment in a two-dimensional map and graphs of the energy mix management associated with this environment. This approach can serve as a decision-support tool, for instance, in the implementation of a new photovoltaic field or wind turbines.

The energy needs considerably increase with the economic development of a country. The promotion of renewable energy sources was enhanced because of global awareness of fossil fuel depletion and climate changes induced by their use. The renewable energy sources are, however, intermittent in nature. Alternative solutions such as the integration of renewable energy systems into the conventional electric grids have been recommended. The integration approach uses photovoltaic, wind, and other renewable energy sources to supply sustainable energy to the built spaces during peak loads or electric back-up. In this article, we proposed a new approach to manage the energy flow in a smart grid. Two algorithms were developed to manage the integration of renewable sources combined into a storage system into a conventional power grid. The first algorithm aims to smooth the consumption peak and reduce the extraction from the conventional grid while the second aims to maximize the use of renewable energy depending on the energy demand. Reliability tests of the algorithm behavior have been conducted in comparison to the HOMER software and the results show a maximum relative error of 4.78% on the management of grid extraction. These algorithms are based on scenarios and operational parameters to optimize the integration of renewable energy in the current electricity network. Their application will reduce the negative impact of fossil energy and enhance the energy transition.
