“…Appropriate temperature and suitable levels of nutrients are important for plants to grow. There are so many types of plants that can be grown up using the hydroponic method such as lettuces, tomatoes, and celery [1], [2]. In hydroponics, all its nutrients are delivered directly to it's roots by bypassing the soil, which is much faster and more efficient at providing all the nutrients need to the plant.…”

The global agriculture system faces significant challenges in meeting the growing demand for food production, particularly given projections that the world's population will reach 70% by 2050. Hydroponic farming is an increasingly popular technique in this field, offering a promising solution to these challenges. This paper will present the improvement of the current traditional hydroponic method by providing a system that can be used to monitor and control the important element in order to help the plant grow up smoothly. This proposed system is quite efficient and user-friendly that can be used by anyone. This is a combination of a traditional hydroponic system, an automatic control system and a smartphone. The primary objective is to develop a smart system capable of monitoring and controlling potential hydrogen (pH) levels, a key factor that affects hydroponic plant growth. Ultimately, this paper offers an alternative approach to address the challenges of the existing agricultural system and promote the production of clean, disease-free, and healthy food for a better future.

“…There is evidence that green roofs may boost cities' biological diversity if implemented widely [56,57]. Green roofs make recreational areas available, create a food supply, offer aesthetic benefits, promote good health, and serve as a contemporary architectural design for sustainability [58,59]. Green envelopes with vegetation increase the property's worth, reduce background noise, contribute to a more comfortable temperature in the environment, and reduce heating and cooling costs by improving a building's insulation [60,61].…”

Global temperatures have continued to rise for decades, partly due to human-caused greenhouse gas emissions and subsequent urban heat island (UHI) effects. This current research examines the benefits of urban greenery by studying the impact of green roofs and walls of a building on thermal behavior and heat transfer in a warm and humid climate. This simulation study discusses the importance of greening systems in improving thermal comfort and minimizing the causes of UHI by assessing an integrated green building design. Using the simulation software DesignBuilder, the significance of greening systems, green roofs, and walls in enhancing thermal comfort and reducing the factors that contribute to UHI is investigated. The simulation results are based on the building’s energy usage in hot and humid regions while featuring green roofs and walls. The simulation results indicate a considerable positive impact of greening systems in improving the urban environment in hot and humid tropical climates. Air temperature, radiant temperature, humidity, and solar gain are decreased by urban greening. The total energy consumption and district cooling demand of buildings with green roofs and walls are reduced by 10.5% and 13%, respectively. The greening systems substantially improve air quality and building’s energy efficiency. Thus, the present study‘s findings can benefit urban designers and dwellers in devising strategies for establishing green spaces in congested urban environments by integrating green technologies and systems into built environments.

“…Hydroponic cultivations have mostly been studied as a more sustainable alternative to traditional agriculture in terms of water and soil consumption [7] and for their easy implementation in urban areas, determining an increase in crop production for the population, a reduction in food transportation and waste and the improvement of food safety [8] thanks to a production policy based on "controlled environment agriculture" [9]. Only few authors have focused on the thermal benefits [3][4][5][6] of hydroponic systems as green roofs technologies however, studies on buildingintegrated agriculture (BIA) [10] have investigated how these systems can contribute to optimizing their energy and resource consumption through the trade-off between the building and the cultivation system [11]. If studies report comparable thermal and energy performances to traditional green roofs, hydroponic systems can likely become their viable competitors due to their added potential in terms of reduced resource consumption and subsequent lower environmental impact.…”

One of the main goals of building design is indoor comfort, regardless of its use (residential, educational, institutional, etc…). However, to achieve indoor comfort, buildings require a significant amount of energy. In the last decades, designers and researchers have been studying new strategies to improve buildings’ energy efficiency, with the purpose of mitigating the negative environmental impact caused by heavy energy consumption. Green roofs have been one of the most investigated solutions because of the many thermal benefits they can offer, and amongst these, hydroponic green roofs gained momentum. This study aims to analyse the rooftop temperature reduction provided during the hot months by a hydroponic green roof, compared to a traditional roof slab and an extensive green roof, in order to assess the different performances of these systems. In situ experiments were conducted to collect surface temperature of the roof slab during summer, with and without the hydroponic system, in order to assess the potential temperature reduction, which subsequently affects the heat flow through the roof and therefore the indoor air temperature. The results show a significant decrease in the external surface temperature of the roof compared to the bare roof, but also slightly better performance compared to the extensive green roof. Despite first promising results, the knowledge on hydroponic green roofs performance remains limited and some drawbacks need to be assessed. For these reasons, further in situ testing should be carried out, under different climatic conditions and experimental setups.
