“…The database adopts a classification of RA typologies (Figure 1) based on growing conditions (protected or nonprotected) (RA type), cultivation aim (farming purpose) and building characteristics (building type) (Thomaier et al, 2015;Buehler and Junge, 2016;Nasr et al, 2017) and includes a subdivision depending on whether the structure is devoted to food production only (monofunctional building) or to other uses (multifunctional building) (Buehler and Junge, 2016).…”

“…A third protein source that may be an interesting alternative to SBM are protein-rich microalgae such as spirulina (Arthrospira platensis, 730 g CP/kg DM [20]). Phototrophic spirulina can be cultivated in open ponds or closed photo bioreactors [21] on non-arable land such as rooftops [22] and at a high water-use efficiency [23]. When compared to soybean and rapeseed, spirulina provides a protein yield 15 to 20 times greater per unit area [23,24].…”

The aim of the study was to investigate the complete substitution of imported soybean meal in beef cattle diets and the consequences on performance, meat, and adipose tissue quality. Thirty growing crossbred Limousin bulls, with an initial bodyweight of 164 ± 13 kg and 4.3 ± 0.3 months of age, were fed a grass/maize-silage based diet with little additional concentrate (0.5:0.3:0.2). Concentrates contained either soybean meal (positive control), faba beans, pumpkin seed cake, or spirulina (Arthrospira platensis), resulting in about 226 g crude protein (CP)/kg concentrate dry matter (DM) and 158 g CP/kg total diet DM. A grain-based concentrate providing just 135 g CP/kg concentrate DM and 139 g CP/total diet DM served as a negative control. Bulls of all groups had comparable average daily gains (1.43 ± 0.1 kg) and feed intakes (6.92 ± 0.37 kg). Carcass and meat quality did not differ among groups. The fatty acid profile of meat lipids was hardly affected. These results indicate that soybean meal can be replaced by any of the tested protein sources without impairing performance or meat quality. Importantly, bulls fed the negative control achieved a fattening and slaughter performance comparable to that of the protein-supplemented groups without affecting meat and adipose tissue quality. Thus, the present findings suggest that feeding crossbred bulls a grass/maize-silage based diet does not require additional protein supplementation.

“…Green roofs have started to be designed not only in new buildings, but also the roofs of existing buildings are being replaced with green ones. They are diversified in terms of the main aim of roof construction and the way of growing plants [43], depending on the thickness of soil substrate [44]. Thick substrates create an opportunity for more diverse crops, but due to the heavy weight of soil saturated with rainwater, they are not suitable for use on the roof of a building, the structure of which is not prepared to withstand large additional loads.…”

“…Besides the ability to produce food directly in the place of residence, cultivation on the roofs of multi-family buildings provides benefits by integrating residents and educating people who, due to living in city centers and a lack of access to private land, would otherwise not have contact with cultivation in their own garden [43,51]. The crops can be part of a wider roof management strategy, including, inter alia, furnishings with garden furniture, rooms for individual office work, gyms or spaces for residents to share their passions [52].…”

Transformation of Socialist Realistic Residential Architecture into a Contemporary Sustainable Housing Habitat—General Approach and the Case Study

This article deals with the problem of multi-family housing implemented in the 1950s in Poland. Buildings from this period are located in the central districts of cities, and are well-connected and equipped with service infrastructure, but due to the small size of these flats, their low standard and poor technical condition, they are not sufficiently attractive for middle-class people and developing families. The consequence of this is the social selection of residents and the disappearance of neighborly relations. In this article, the authors present a balance sheet of the shortcomings and advantages of these buildings, and against the background of contemporary requirements for housing, resulting from the theory of sustainable development, they indicate possible directions for modernization. Detailed solutions are presented for a specific housing complex located in Rzeszów. The development of flat roofs and the introduction of functions integrating the community of residents are the significant elements of the project. Due to the fact that the functional layouts of stories, the structure of buildings, and to a large extent the spatial arrangement of residential complexes were unified in the 1950s throughout the whole country, the presented concept may serve as inspiration for similar projects undertaken in any other city in Poland.
