“…Climate-adapted urban planning means reducing sealing in the city, creating, maintaining, and where possible, expanding urban green space (UGS). Permeable surfaces (permeable tiles) also contribute to this, as do facade greening and green roofs [8,10,[96][97][98][99]. It is particularly important to implement the measures on a large scale to counteract the effects of sealing.…”

“…Detailed information should be used for climateadapted resilient urban planning to cover nature-based as well as artificial solutions for heat mitigation (e.g., unsealing, green facades, green roofs, white roofs, PV-equipped roofs, new unsealed surfaces, cool shelters, cool fountains, the optimization of street configurations and parks, etc.) [7][8][9][10][11].…”

Citizens in urban areas are affected by the urban heat island (UHI) effect, resulting in increased thermal heat compared to rural areas. This threat is exacerbated by global climate change. Therefore, it is necessary to assess human thermal comfort and risk for decision making. This is important for planners (climate resilience), the health sector (information for vulnerable people), tourism, urban designers (aesthetics), and building architects. Urban structures modify local meteorological parameters and thus human thermal comfort at the microscale. Knowledge of the pattern of a city’s UHI is typically limited. Based on previous research, gam were built to predict the spatial pattern of the UHI in the city of Karlsruhe. The models were trained with administrative, remotely sensed, and land use and land cover geodata, and validated with measurements in Freiburg. This identified the hot and cold spots and the need for further urban planning in the city. The model had some limitations regarding water bodies and anthropogenic heat production, but it was well suited for applications in mid-latitude cities which are not topographically characterized. The model can potentially be used for other cities (e.g., in heat health action plans) as the training data are freely available.

“…The impact of implementing green roofs on a building can be estimated, particularly in terms of rainwater accumulation. For comparative purposes, the runoff coefficient for green roofs was evaluated in accordance with several standards: the German standard (DIN 1986-100:2016-12 2016) [23], the Austrian standard (ÖNORM B 2501 2016) [24], the Slovak standard (STN 73 6760 2009) [25], and the FLL directive (FLL 2008) [26][27][28][29][30]. Tables 1 and 2 present the runoff coefficients as per these various standards (DIN 1986-100:2016-12 2016; ÖNORM B 2501 2016; STN 73 6760 2009; FLL 2008), contingent on the thickness of the substrate.…”

Addressing climate change necessitates a conscious transition toward sustainable infrastructure solutions. Our vision involved transforming an experimental area into the University Experimental Center. This experimental building serves as a model for gray infrastructure implementation, taking into account its dimensions, layout, flooring, and material composition. Our study aims to compare the retention capacities of various types of vegetated roofs, as determined by different legislations. The findings indicate that the outcomes vary based on the regulations used. This variation subsequently influences the design of associated infrastructures, such as rainwater drainage systems, and the design of stressed structures. This is due to the impact of water quantity on the thermal response of a stressed structure. The water used to irrigate the vegetation layer, along with the water retained by the upper roof, has a positive impact on both the building and its surroundings. Initially, the system comprised two functional components: vegetated roofs and a reference roof. The integrated experimental roof shell, in conjunction with the frame, forms an autonomous system. This system serves as a segment for quantifying water retention, humidity, and temperature across diverse green infrastructure substrates. We analyzed the thermal response of experimental roof constructions and monitored the influence of water and precipitation. Our results indicate that the height of the substrate affects not only the retention capacity but also the thermal response of the vegetated roof.

PurposeThe study aims to develop recommendations for optimal Internet of things (IoT) based solutions for a smart precision irrigation automation platform using morphological thinking (MT). The smart irrigation system (SIS) can be applied for green roof and green wall (GRGW) design by studying the relationships and configurations that will be analyzed, listed and synthesized, representing “solutions spaces” and their possibilities.Design/methodology/approachThe research examines studying various cases of SIS; and assessing and analyzing the identified case studies through a decision support system (DSS) considering several factors regarding IoT, plant characteristics, monitoring, irrigation system and schedule, climate, cost and sensors used.FindingsTo develop recommendations for optimal IoT-based solutions for a smart precision irrigation automation platform.Originality/valueThe research paper analyzes and proposes a simultaneous solution to two conflicting problems. On the one hand, the paper proposes to apply greening of walls and roofs in hot arid regions, which will achieve greater environmental comfort. However, this is extremely difficult to implement in hot arid regions, since there is an objective problem – a lack of water. At the same time, the paper proposes the most rational approaches to organizing an irrigation system with the lowest water consumption and the highest efficiency for landscaping. Accordingly, this paper focuses on evaluating different types of SIS about the hot-arid climate in Qatar. The study aims to develop recommendations for optimal IoT-based solutions for a smart precision irrigation automation platform, which can be applied for green wall and roof design.
