“…Due to climate change and external pollution in this water, algae and biological life are affected [15]. Yet, the abounded availability of the organisms and macroalgal biomass in the marine ecosystem are considered as producers of clean source energy, oxygen, heat, and biological compounds biomass such as nutraceuticals, food, and fertilizers [7], [16], [17]. The global attention towards microalgae as a source of biofuel is mainly due to their ability to be converted into electricity and heat through the higher efficiency in the photosynthesis process [1].…”

“…Another usage of algal cells that they are being integrated into the design of solar thermal collectors because of their ability to improve indoor air conditioning systems, lighting systems, shading, etc. As an application, algae photobioreactors known as "PBR" became part of the building components that have been considered as a nature-based alternative to large glass surfaces [7]. One of the PBR benefits that they can provide shade during sunny days by cooling the building beside their long lifetime of 20 years, with an average of 1,480 kg of biomass production during this period [18].…”

“…Therefore, the integration of green architecture became a good example to reduce carbon emissions and find renewable resources of energy to support the global climate action change summit. One of these green applications is biomaterials and algae which started to spread with the aid of technology [7]. Algae are one of the main components of aquatic organisms and plants that serve as the base of the food chain [8].…”

In Egypt during the extreme heat in summer, numerous amounts of air conditioners -that provide a cooler environment -are producing a huge amount of outlet wastewater. The continuous flow of this water causing great damage to buildings' façades. Therefore, the paper presents an innovative product solution made from algae that aim to reuse this wastewater as a self-watering landscape façade element that acts as an irrigation system. The prototype is designed from concept to manufacturing to implementation based on 3D printing with a bio-algae filament. With the dual algae ability in producing O2 and absorbing CO2, the fabrication follows a spiral engrave path to collect and cool the water droplet and ensure a smooth flow to be suitable for plantation. A path strategy is used during the printing for minimal structure supports aimed at saving unnecessary material waste and fabrication time. Solar radiation and water simulation are tested to measure the effect of the algae and to ensure the water fluidity from the AC tube till reaching the soil. The solar radiation results record a solar reduction from 316.43 to 80.71 kWh/m 2 after adding the algae panel to a building façade with a decrease of 6°C in the water temperature. The design demonstrates highly significant materials and resource savings, where no supports are needed during printing. The finding addresses the manufacturing of a low-cost algae product using cleaner technology as additive manufacturing. Given the alarming increase in the new industrial materials, algae will allow designers to explore their benefits regarding their O2 production and CO2 absorption, which will influence the façades to be smarter and sustainable using large-scale of PBRphotobioreactors -applications as a nature-based alternative to large glass surfaces with the potentials of additive manufacturing. This can reduce plastic production using fossil fuels to be eco-friendly.
