A main purpose of using binary solutions as phase change materials is to benefit from the latent heat or enthalpy difference at melting. In the design of latent heat storage systems, the enthalpy change of the PCM has to be known with high precision. In this article, we show with the help of experimental data and numerical analysis why the use of differential scanning calorimetry measurements is troublesome for dispersed binary solutions inside an emulsion. The article shows how an enthalpy-phase diagram of salt solution during the eutectic and progressive melting can be constructed, gives chart with enthalpy values, apparent specific heat capacity and ice concentration as a function of temperature and initial salt concentration. © 2012 Elsevier B.V.

The application of phase change materials (PCMs) for building applications has received considerable attention in recent years due to the large storage capacity and isothermal nature of the storage process. This paper summarizes the results of a physical model and analysis of thermal energy storage and temperature control achieved using mortar incorporating microencapsulated PCM. The validity of the numerical code used is ascertained by comparing our results with previously published results. The effect of different parameters such as the heating/cooling rate and the mass fraction of the PCM on the thermal behavior of the mortar is also analyzed. © 2012 Elsevier B.V.

In this paper, we reported the current status of the energy sector and its future challenges in Morocco. Recent strategies deployed by the government for sustainable development were reviewed and discussed. These strategies put the transition to renewable alternatives on the top of the national policy implications for energy security and low-carbon economy. We have also suggested a methodological tool to prioritize energy alternatives for power generation. It was found that wind energy is the most appropriate power generation alternative in Morocco at the current level. © 2015 Elsevier Ltd.

The building sector is considered as the biggest single contributor to world energy consumption and greenhouse gas emissions. Therefore, a good understanding of the nature and structure of energy use in buildings is crucial for establishing the adequate future energy and climate change policies. Availability of the updated data is becoming increasingly important in order to allow a rigorous analysis. In this paper, recent data on the world energy consumption in both residential and commercial buildings are reported. Past situation, current status and future trends are discussed and analyzed for selected countries. A breakdown of buildings energy consumption is realized in order to determine the influencing key parameters. A whole section of this paper is dedicated to give an overview of measures and policies adopted by different countries, allowing the monitoring, management and reduction of the energy consumption in buildings. Critical aspects of these policies are discussed based on the feedback of the early adopters. © 2015 Elsevier Ltd.

In addition to their harmful impact on the environment, air-conditioning applications account for a significant percentage of total energy utilization; thinking about clean resources becomes a world priority. Solar cooling systems using either adsorption or absorption technologies show a great potential since they can use a permanent energy and operate with environmentally safe working pairs. This paper investigates the potential of solar air-conditioning systems in Morocco (enjoying different climates) through a comparative study between conventional and solar closed cycle processes based on economic and environmental indicators. Accordingly, annual simulations in 6 climatic zones were performed to estimate cooling loads for a typical Modern Moroccan House. The major finding of this work is that solar air-conditioning systems in hot climates must be an attractive alternative to mitigate CO2 emissions and increase energy savings. However, the high installation cost is a main obstacle facing their implementation. © 2015 Elsevier Ltd. All rights reserved.
