“…Controlled environment agriculture (CEA), such as greenhouses, offers year-round food production possibilities [67]. Utilizing intelligent shading systems, smart glass, sensors, IoT, and AI [68], greenhouses precisely control conditions such as temperature, light, and humidity [73], increasing yield per unit area compared to traditional methods and conserving water through precision irrigation [48]. Some greenhouses capture and reuse water, further reducing water use [48].…”

aim, which are adaptation and mitigation [31]. While mitigation focuses on reducing the causes of climate change, adaptation involves adjusting to its impacts [12]. Adaptation, therefore, is essential to manage unavoidable impacts, while mitigation is needed to limit the long-term changes in climate. The optimal mix of adaptation and mitigation measures will depend on local and regional factors, including climate change impacts, economic structures, and societal values.

“…The greenhouse case study is based on meteorological data in the south of Spain (Almería, latitude 36 • 51 N, longitude 2 • 22 W). The type of greenhouse is the multi-tunnel type, which has good climatic and structural behavior [8,23]. The greenhouse materials are a gabled plastic roof with an area of 1120 m 2 , and tomatoes are cultivated in the greenhouse over a large cycle of 11 months.…”

Sustainable greenhouses have gained relevance in recent years due to their potential to reduce the carbon footprint of the agricultural sector by being integrated with renewable systems, contributing to the decarbonization of energy. Although solar technologies tend to be more accessible to cover the system’s energy demands, greenhouses are subject to installation area restrictions, limiting their energy potential. This research evaluates the energy advantages of hybridizing solar thermal collector fields with photovoltaic module fields to cover a greenhouse’s cooling and heating demands. For this purpose, the solar thermal field and the photovoltaic solar system were simulated with TRNSYS and MATLAB, respectively, while a method was developed to simulate the performance of a single-effect absorption chiller that was validated using the temperature measurements of a chiller in operation. The results show that the general method maintains differences between measurements and simulation smaller than 5% with set temperatures between 5.5 and 12 degrees Celsius. The hybrid system, with an air-to-water chiller as the main machine and absorption chiller, reached a solar fraction of 0.85 and a fractional energy saving of 83%. This represents a 27% reduction in area concerning an individual solar thermal system. This research highlights that the solar hybrid configuration reduces fossil energy consumption by improving the global efficiency of energy conversion, thereby reducing the area of the solar field.

“…In recent years, research has been directed at developing novel advanced cooling systems or incorporating different renewable energy sources into established cooling systems. For example, geothermal cooling systems have shown good performance as sustainable technologies that enable reaching suitable greenhouse temperatures [20]. The principal part of the geothermal cooling system is a pipe placed underground that exploits the cool temperature of the earth's surface and exchanges the warm air inside the greenhouse [21] with the cool air from the earth.…”

The world’s population is expected to increase by nearly two billion in the next 30 years; the population will increase from 8 billion to 9.7 billion by 2050 and could peak at 10.4 billion by the mid-2080s. The extreme weather triggered by global climate change has severely hit crop yields in open-field cultivation and led to an increase in food prices. Furthermore, in the last few years, emergency events such as the COVID-19 pandemic, wars/conflicts, and economic downturns have conditioned agricultural production and food security around the world. Greenhouses could be efficient cultivation systems because they enable food production in a sustainable way, limiting contact between pollutants and plants and optimizing the use of water, energy, and soil. This paper proposes a novel dome-soilless greenhouse concept for tomato cultivation in the Mediterranean area. The proposed greenhouse is fixed on a sea platform to take advantage of the seawater cooling environment and to integrate water consumption into a hydroponic system. In order to evaluate the best covering solution material to adopt, a few thermal and photometric characteristics of greenhouse covering materials were evaluated using a simplified method. A dynamic simulation was carried out to compare the proposed seawater cooling system with a conventional cooling tower in terms of the electric energy spent to maintain the inside temperature range at 13–25 °C across all seasons in the year. The proposed heating, ventilation, and air conditioning (HVAC) system allowed a total annual energy saving of more than 10%. The energy saved was a result of the better cooling performance of the seawater heat exchange that allowed energy saving of about 14% on cooling. The comparison between the model characterised by a 6 mm polycarbonate coupled with UbiGro film and a seawater cooling system, and the model including a 6 mm polycarbonate coupled with a clarix blue film covering and a tower cooling system highlighted energy saving of about 20%. The obtained results indicate possible future directions for offshore greenhouses to carry out independent production together with the integration of photovoltaic modules, water treatment plants, and smart remote-control systems.
