Morocco has resolutely committed to the green transition of its economy by opting for industry decarbonation, which now imposes itself as an essential access criterion to foreign markets. Intending to include energy efficiency in the leading players in energy-intensive industries, this paper has the main objective of contributing to a better understanding of the decarbonation plans potential impact, taking the example of solar energy integrating opportunities as an action for a thrifty, sustainable, and low carbon Moroccan industry. Indeed, the paper focuses on the industrial textile sector, such as the energy-intensive industry. This sector is the first employer and the most important industrial activity; it is also an icon and the oldest industry in Morocco. This study examines the energy, economic and environmental fallout, evaluating the productions, the investment and the CO₂ emissions limit. Besides, the energy industrial sector is characterized by a strong dependence on fossil imports, which increases the energy factor and price. In this regard, several geographical sites and factories were studied under six climatic regional conditions, proposing the most optimal and sustainable configurations for each location and present models with scopes and levels of energy and environment gains and investments that can inspire the sector actors. Then the present work must install concepts by inspiring local factories, accompanying the national vision, and resizing the industrial ecology. In this paper, a power of 8.88 MW is the total power installed, which provides an annual total of 8484.65 tonnes of CO₂, with an average payback time between 2.6 years and 4.5 years, and attractive economic parameters, with an LCOE of 0.034 $/kWh and $181,863 for the NPC, those outputs shows the importance of environmental gains that the generalization of this strategic vision can achieve.

Energy efficiency has emerged as a crucial focal point in global agendas, being recognized for its pivotal role in combatting climate change, bolstering energy security, and fostering economic growth. Governments worldwide are formulating ambitious targets and enacting comprehensive strategies to optimize energy utilization across various sectors. This involves the formulation of policies, provision of incentives, and facilitation of collaborations to encourage energy-efficient practices, ultimately steering towards a sustainable and energy-efficient future. Notably, the residential sector stands as a pivotal component in these efforts due to its substantial share of energy consumption. This paper evaluates the strategic vision of Morocco concerning energy efficiency within the residential sector from its inception to the projected initiatives up to 2030. The analysis focuses on the current iteration of thermal regulations and its implications. Although specific numerical outcomes are not discussed herein, the implementation of these regulations is observed to yield notable benefits, including reductions in energy bills and gains in annual primary energy. These advantages are estimated to result in a substantial decrease in final energy consumption, equating to significant savings for end-users. Additionally, to cover the expenses associated with building repairs and thermal enhancements, an extra fee is levied, varying based on building typology and climatic region. Despite this additional investment, the associated costs typically exhibit a favorable payback period, on average, underscoring the efficacy of regulatory and profitability measures in driving energy efficiency within the residential sector. This paper examines Morocco’s strategic approach to energy efficiency in the residential sector, focusing on its thermal building regulation RTCM (Moroccan thermal regulation on construction). Energy efficiency is recognized as essential for reducing GHG (greenhouse gas) emissions, enhancing energy security, and lowering costs. Using simulation models across six climatic zones and three residential building types, the study highlights RTCM’s significant impact—achieving national energy savings between 39% and 68%. Despite added costs for thermal improvements, the measures show favorable payback periods, confirming RTCM’s strong energy and economic performance and its potential role in shaping future policies.

This paper presents a strategical project for the new version of the Moroccan energy policy. It highlights the technology of solar water heaters (SWH), studying energy, economic and environmental gains of SWH generalization to satisfy the total resident need proposing a new strategic version diversified in terms of adopted technologies (more than green electricity). A detailed analysis of thermal performances and economic profitability of direct thermosyphon solar water heaters (TSWH) for residential requirements in Morocco. The optimum design parameters were defined and investigated using the dynamic TRNSYS simulation program. The optimum system was simulated under the six climatic conditions of Morocco in order to assess the related performances in terms of the collector efficiency and solar fraction. The major finding of this work is that large-scale integration of TSWH into Moroccan residences could provide up to 70% of thermal energy loads. An economic study was also developed to predict the life-cycle savings generated by the generalization of this technology in Morocco for all residential building’s categories. Approximately 1250 million USD as national saving on the total energy bill can be achieved. The environmental effects were also assessed to achieve the aims of this work and to evaluate the CO₂ emissions avoided due to this environmentally friendly solution.

This paper aims to highlight the potential of solar water heater installations in Morocco. The project involves the comparison of active and passive solutions for energy efficiency in buildings. To this end, a numerical simulation model of solar water heater installations is created under TRNsys. Three hot water demand scenarios (Low, Standard, and High) were taken into account for the six climatic zones defined in the Moroccan thermal regulation of constructions. The same software (TRNsys) is used to model a pilot building consisting of 16 flats. Energy efficiency actions have been applied to the building envelope (insulation and glazing) and simulations are made for the six areas. The simulation results comparing energy and financial savings show the influence of subsidized gas prices on solar water heaters’ relevance despite significant energy savings. This work proves that solar water heaters will be a primary obligation for Morocco, taking into account changes in butane gas prices.

The Moroccan Ryad, a cherished architectural treasure in North Africa, symbolizes cultural richness and architectural legacy. This paper advocates an inventive strategy to preserve and rejuvenate the Ryad as an energy-efficient model, intertwining modern sustainability principles. Employing a multidisciplinary approach, this study delves into the fusion of traditional Ryad design with contemporary sustainability, tackling energy efficiency, resource conservation, and cultural heritage challenges. Examining historical construction methods, material choices, and spatial arrangements alongside sustainable building practices, this paper showcases case studies of newly constructed sustainable Ryads. These examples spotlight strategies like passive solar design, renewable energy incorporation, water conservation, and local material use, augmenting energy performance while fostering cultural continuity through eco-friendly materials and traditional craftsmanship. This research also explores the social and economic impacts of this sustainable Ryad model, including its potential to boost tourism, generate employment, and engage communities. Additionally, it addresses the role of public policy in supporting sustainable practices for preserving Moroccan cultural heritage. By amalgamating culture, sustainability, and energy efficiency, this paper envisions a new role for the Moroccan Ryad, positioning it not only as a guardian of heritage but also as a symbol of environmentally responsible architecture—a model applicable to culturally rich regions globally.
