“…Since they are opaque systems, microalgae bio-facades can decrease the heating and cooling demands of the building and improve the overall energy efficiency of the building. The photobioreactor systems on the facade can reduce energy consumption by up to 50% and provide thermal insulation [126][127][128]. Buildings can gather required heat and electricity from microalgae, and this technology can serve as an alternative system.…”

Living organisms have been progressively used by designers to propose alternative design outcomes aiming towards more ecological aspects. The design development and manufacturing of new materials or design components from living organisms are more achievable in textile, fashion, or product design than in architecture and construction due to the scale, multi-layer constraints, and requirements. The aim of this paper is to investigate the interdisciplinary framework, the opportunities, and limitations of introducing living organisms into the design process, including the implementation from the design ideas to prototyping until commercialization. In this paper, we focus on three types of living organisms: algae, bacteria, and fungi. Firstly, we overviewed and studied existing projects and experimentations to understand the design process and fabrication of living organisms in other domains in comparison to architecture. Secondly, we selected three case studies in architecture for each organism to analyze. We collected the data and conducted interviews with multidisciplinary experts involved in each case. Our findings show a better understanding of the potential to integrate living organisms in architectural design, the advantages, and the difficulties towards ecological awareness. The results from the interview and a comparative analysis show the advantages and constraints of each case. The future outlooks towards the use of living organisms as part of design in architecture are also discussed.

Losing heat additionally results in greater energy expenses and waste of resources. In any construction building, the façades ensure the heat transfer between the exterior and the interior surfaces of the structure. The thermal transfer of a façade is dominated by conduction. This exchange makes them responsible for guaranteeing thermal comfort to the occupants. Uninsulated outside walls can cause substantial heat loss, particularly during the winter. The heat is able to pass via such façade, leaving it hard to keep the appropriate temperature inside the construction. Furthermore, there is traditional outside insulation that uses isolative boards, which come in a variety of materials. They require a coat of render on top to provide additional protection from the outdoors as well as a beautiful finish. Impermeability and additional costs are the main disadvantages of such systems. In recent façades (rainscreens), the use of ventilated or unventilated cavities influences the thermal resistance. The rainscreen tends to have lower thermal transmittance than the stone façade. The thermal transmittance of the curtain wall depends on the thermal transmittance of the glazing and that of the mullions/transoms including the spacer of the double-glazing, calculated from a 2D analysis, so the total thermal transmittance will be a weighted average value. Surface or interstitial condensation occurs when humid air touches a surface T less than the dew point temperature; it is less likely to occur in a recent façade than in an old one. The aim of this topic is to achieve an energy comparison between two identical resident structures. The first one was provided with an old façade; however, the other house had a recent façade. The obtained results show an important saving of energy of the recent façade (refund in electricity bills), ensures thermal comfort, reduces embodied carbon, and protects the planet, the atmosphere, and the environment.
