“…However, applicable design methods might differ for the same design steps due to AOF working principle. For instance, the AOF will consider the climate conditions, but mainstream climate analysis does not capture the climatic characteristics which condition the correct design of AOF [76]. For this reason, the particular AOF design methodologies and tools which serve to assist at different design steps were detected in scientific papers.…”

“…However, the particular heat transfer mechanism of AOF makes the application of standard climate analysis unsuitable. In [76], a new methodological approach was proposed called dynamic climate analysis (DCA), of which the working principle is briefly summarized in Table 2. This approach extracts relevant transient information from weather files when designers define the location, geometry and the orientation of the Opaque Facade Systems and narrows down the preferable Adaptive Opaque Facade Responses (AOFR).…”

“…It should be remembered that the performance of Adaptive Facades is mostly determined by local weather conditions and internal heat gains. That is why DCA was used to check that selected locations for the workshop were the suitable ones [76]. Moreover, similar climates were proved to be promising in previous research works [72,76].…”

Adaptive Opaque Facades (AOF) is an innovative concept with potential to achieve low carbon energy buildings. However, so far AOF are not integrated in the construction industry. One remarkable issue that designers have when dealing with alternative low-carbon technologies, such as AOF, is the absence of previous built experiences and the lack of specialised technical knowledge. Design roadmaps can be convenient solutions to guide pioneer low carbon technology applications. This work presents a roadmap to assist the performance-based early-stage design process of Adaptive Opaque Facades. Previous research developed new approaches and tools to assist on the construction definition of AOF, so that their adaptive thermal performance was considered when specific design decisions needed to be made. The roadmap presented in this paper organises the implementation sequence of each methodological approach and tools in different design stages, which aims to provide a holistic design approach for AOF. The usability of the roadmap was validated in a workshop called “Performance-based Design and Assessment of Adaptive Facades” with master students representing the target group of this roadmap. Even though these students had never heard about AOF before, they could successfully design, define the early-stage characteristics of an AOF and quantify the thermal performance of their AOF designs. The roadmap was proven to be a useful support, which might make the implementation of AOF more approachable in the future.

sector accounts for 34% of energy demand and 37% of energy-related CO 2 emissions globally. [2] In buildings, a major portion of the footprint concentrates in the first year of the life cycle and results from embodied emission of material and components. This relative contribution is expected to reach values as high as 50% of the total emissions as energy efficiency in buildings increases. [3] At the moment, despite the continued power sector decarbonization and the adoption of climate-change mitigation policies, buildings remain offtrack to achieve carbon neutrality by 2050. [1] Facades constitute the main building boundary between external and internal environments, controlling the flow of energy and matter inside buildings. For this reason, they considerably impact the environmental conditions of indoor spaces, user satisfaction, and operational efficiency. [4] Therefore, improvements in the performance of building facades are critical to meet most of Net Zero Emissions by 2050 scenario reductions in energy use. [5] To meet the performance requirements prescribed by the building codes, advanced facades systems have been proposed, which can tune their behavior in response to variable boundary conditions [6][7][8] and feature smart materials allowing integration of and switching between multiple functionalities. [9][10][11] Apart from the operational Façades are the primary interface controlling the flow of solar energy in buildings and affecting their energy balance and environmental impact. Recently, large-scale 3D printing (3DP) of translucent polymers has been explored as a technique for fabricating façade components with bespoke properties and functionalities. Transmissivity is essential for building facades, as the response to solar radiation is crucial to obtaining comfort and greatly affects electricity and cooling demands. However, it is still unclear how 3DP parameters affect the optical properties of translucent polymers. This study establishes an experimental procedure to relate the optical properties of PETG components to design and 3DP parameters. It is observed that printing parameters control layer deposition, which governs internal light scattering in the layers and overall light transmission. Moreover, the layer resolution determines angle-dependent properties. It is shown that printing parameters can be tuned to obtain tailored optical properties, from high normal transparency (≈90%) to translucency (≈60%), and with a range of haze levels (≈55-97%). These findings present an opportunity for large-scale 3DP of bespoke façades, which can selectively admit or block solar radiation and provide uniform daylighting of a space. In the context of the building sector decarbonization, such components hold great potential for reducing emissions while ensuring occupant comfort.
