“…The symbiosis between the microalgae culture system and the building can also be beneficial for medical purposes [21], human food [22] and animal feed production [23], wastewater treatment [24,25], and production of bio-products [26] as well as energy [27]. Yet, there have been few attempts to integrate algae bioreactors into building envelopes as a kind of green façades [28] for thermal regulation [29], despite there are numerous researches on green building envelopes in terms of thermal and energy performance [30][31][32][33]. Besides, this technology is still in its infancy stages [8] in both research and development, and numerous challenges remain to be addressed before the wider application of this technology.…”

“…Many research works have proposed mathematical models useful to describe the heat fluxes in GFs, thus assessing their thermal performance [40][41][42][43]. The different heat transfer mechanisms have been investigated: solar radiative exchange [44], long-wave radiative transfer [45,46], and convective heat flux [47]. The latent heat transfer due to the plant's evapotranspiration has also been studied and quantified [41,48,49].…”

Buildings consume a significant part of the world’s resources and energy. The growing environmental awareness and urgent need to reduce energy consumption have highlighted the importance of introducing innovative solutions as nature-based systems in new buildings’ construction and retrofitting. In this regard, green façades that integrate vegetation into building envelopes are attractive. This paper presents a bibliographic analysis, based on science mapping, of the available literature on green façades from 1999–2022 with a focus on the thermal effect on the building and on the surroundings. The objective of this study is to reveal the structure and the evolution of the research activity in the field, outlining the main research topics and the future research directions. The analysis was performed on a dataset of 270 documents. The results indicate a growing interest in this topic over the last six years and the multidisciplinary dimension of the studies. The keyword cluster analysis indicates the emergence of three main search topics: thermal behavior and energy modeling; urban design and large-scale effects; sustainable buildings management. A greater future dissemination of green façades could be enabled by further research results based on the application of a multidisciplinary approach and of standardized methods.

thermal behaviour of green façades in winter climatic conditions fabiana convertino 1* , ileana blanco 2 † , giuliano voX 1a ‡ & evelia schettini 1 § 1 department of agricultural and environmental science disaat, university of bari, italy 2 department of biological and environmental sciences and technologies disteba, university of salento, italy abstract green infrastructures inside cities represent an effective strategy to face with the increasingly urgent environmental problems. green systems applied to building envelope are among the most applicable and useful solutions. these provide many significant advantages at different scales. green façades (gf) are a typology of vertical green systems, applied to the vertical components of the building envelope. gf allow to save energy for air conditioning, by improving the envelope thermal performances. energy behaviour of gf has been more deeply studied in warm periods, than in cold ones. this paper aims to analyse wintertime energy performances of gf. evaluations were carried out based on the experimental data collected on two gf, in bari (italy), under mediterranean climatic conditions. the experimental set-up included also a bare wall (bw), used as control. the heating effect provided by the greenery was pointed out through statistical and energy analyses. at night-time, the covered walls (cw) were warmer than the bare one up to 3.5°c. the dependence of night-time heating effect on microclimate parameters, as external air temperature, relative humidity and wind speed, was studied. external air temperature was found to be the most influencing factor: as it dropped, the heating effect increased. overall energy transfer through the cw was lower than through the bw at night-time. the long-wave infrared energy radiative losses were reduced thanks to the green layer, which acted as a thermal barrier. these findings proved that gf improve winter night-time thermal performance by reducing energy losses.
