Aims: Improving energy efficiency and creating the quality of the indoor environment in buildings by using environmentally friendly energy sources instead of using fossil fuels that are impossible to recycle and cause environmental pollution is very important. The use of an algal facade system that generates energy sources through building components can be suggested as one of the new efficient alternatives to solve this system. Methods: Microalgae are a type of living microorganism that is in the simplest form of a plant sample and mainly single-celled. Compared to other plant species, these organisms have a very high ability to absorb air pollution due to the high surface-to-volume ratio. By absorbing carbon dioxide from air or water during photosynthesis, they produce about 60 to 75 percent of the oxygen needed by humans and animals, which is 10 times more than a mature tree and photosynthetic grass. Findings: In this research, in the first stage, based on valid scientific articles and library studies, new information is collected and produced, and then the behaviour of microalgae bioreactors is investigated and the possibility of replacing old panels with bioreactors is investigated. Conclusion: The use of alternative energy due to the reduction of energy resources and no destruction of the environment, and the use of environmentally friendly energy using microalgae, in addition to producing the required oxygen, by adding bioreactor panels as an additional view the building has been designed to create privacy and proper view of the building facade.

“…While integrated PBRs offer some advantages in reducing energy for building services, the technology is still in pilot forms and some major challenges need to be addressed before the technology offers net‐zero services, which include—long‐term performance analyses in energy efficiency and effective CO 2 sequestration, characterization of thermal and acoustic insulation, controlling indoor colour due to variation of algae culture density and algae medium discolouring, environmental durability of the panels, protocols for maintenance services, expense of construction, high‐power consumption needed for pumps and artificial light sources (in combination with partial exposure to sunlight) and negative environmental effects such as possible toxins and malodour (Elrayies, 2018 ; Kunjapur & Eldridge, 2010 ; Talaei et al, 2022 ; Wilkinson et al, 2016 ). In general, the high cost of installation and maintenance is offset by the possibility of long‐term environmental benefits, but these are not systematically proven.…”

Disruptive innovation is needed to raise the threshold of sustainable building performance, so that our buildings improve on net zero impacts and have a life-promoting impact on the natural world. This article outlines a new approach to next-generation sustainable architecture, which draws on the versatile metabolisms of microbes as a platform by incorporating microbial technologies and microbially produced materials into the practice of the built environment. The regenerative architecture arising from these interventions includes a broad range of advances from using new materials, to creating bioreceptive surfaces that promote life, and providing green, bio-remediating energy from waste. Such innovations are presently reaching the marketplace as novel materials like Biocement® with lower embodied carbon than conventional materials that adopt microbially facilitated processes, and as novel utilities like PeePower® that transforms urine into electrical energy and bioreactor-based building systems such as the pioneering BIQ building in Hamburg. While the field is still young, some of these products (e.g. mycelium biocomposites) are poised for uptake by the public-private economic axis to become mainstream within the building industry. Other developments are creating new economic opportunities for local maker communities that empower citizens and catalyse novel vernacular building practices. In particular, the activation of the microbial commons by the uptake of microbial technologies and materials through daily acts of living, 'democratises' resource harvesting (materials and energy) in ways that sustain life, and returns important decisions about how to run a home back to citizens. This disruptive move re-centres the domestic-commons economic axis to the heart of society, setting the stage for new vernacular architectures that support increasingly robust and resilient communities.

“…The building-integrated microalgae cultivation system is an innovative technology for high-performance adaptive architecture that offers multiple benefits, including sequestration of CO 2 and production of O 2 to reduce the air pollution, conversion of solar radiation into heat and biomass, providing shading through changes in algal density, and creating sound insulation. It can also make a dynamic exterior vision due to the color changes of the algal culture [44]. Algae façade-integrated buildings as living designs are the result of applying biomimicry in architecture design and planning; they their required energy and water from their location and are adapted to their environment and climate.…”

“…Although the algae-powered buildings have multiple advantages, this technology is still in its early life and there are many technological, economic, environmental, social, and regulatory issues which need to be addressed before wide implementation of these systems. Some major challenges include long-term performance in energy efficiency and effective CO 2 sequestration, thermal and acoustic insulation, the indoor color controlling due to variation of algae culture density, algae medium discoloring, algae panels' durability against climate changes, the need for maintenance, construction, and maintenance costs, and negative environmental effects such as potential toxins and odor produced by harmful algae [29,44,71,93]. Of course, the concern about the high cost can be alleviated due to the long-term benefits.…”

Algae-Powered Buildings: A Review of an Innovative, Sustainable Approach in the Built Environment

Environmental pollution, global warming, energy consumption, and limited natural resources are some key factors from which today’s built environment faces interrelated problems and their management plays a vital role in sustainability. The building sector is involved in 35% of global energy usage and 40% of energy related CO2 emissions. Application of bioactive elements on buildings’ façades is a novel approach for solving the above-mentioned problems. Management of some important factors such as thermal comfort, energy efficiency, wastewater treatment, and CO2 capture is positively affected by bioactive façades because of their environmentally friendly nature. They also have positive effects on global warming, pollution control, social wealth, and sustainable development on a larger scale. The buildings integrated with photobioreactors (PBRs) can meet their thermal needs due to thermal insulation, shading, solar collection, and light-to-biomass conversion. Energy savings up to 30% are estimated to be met by PBR-integrated buildings due to reduced heating, cooling, ventilation, and lighting loads. The above amount of energy saving results in less CO2 emission. Moreover, the algae-integrated buildings can sequester CO2 with an average sequestration rate of 5 g/ft2/day when optimum growing environments and operation modes are implemented. This study is an overview of microalgae intervention and PBR-adapted buildings as an innovative approach for energy efficiency in the built environment with regard to implemented or speculative cases, pros and cons, challenges, and prospects.
