“…Although these measurements may be of some help for such specific conditions (city marathon run circuits), they are not representative of the most common conditions of people walking over dedicated sidewalks, much closer to buildings and affected, at the same time, by street traffic and impervious surfaces' radiation. Therefore, dedicated wearable systems were developed with the purpose to monitor the pedestrian level microclimate parameters directly interacting with the human body and suitable for more reliable energy budget calculation (Nakayoshi et al 2014;Pigliautile, Pisello 2018). In fact, deep personal heat stress analysis at individual scale has been demonstrated to be driven by measurable and nonmeasurable parameters and indexes coming from multidisciplinary fields of investigation such as behavioural sciences, people's susceptibility, medical conditions and environmental comfort outcomes.…”

Urban greenery is a natural solution to cool cities and provide comfort, clean air and significant social, health and economic benefits. This paper aims to present the latest progress on the field of greenery urban mitigation techniques including aspects related to the theoretical and experimental assessment of the greenery cooling potential, the impact on urban vegetation on energy, health and comfort and the acquired knowledge on the best integration of the various types of greenery in the urban frame. Also to present the recent knowledge on the impact of climate change on the cooling performance of urban vegetation and investigate and analyse possible technological solutions to face the impact of high ambient temperatures.

“…in winter conditions in terms of weather. Previous studies showed that correlations between microclimate parameters and urban morphology are more accurate in terms of statistical significance during clear sky conditions and generally stable boundary conditions [32]. Hence, one clear sky day-time and one clear sky evening-time days were chosen for carrying out the presented monitoring campaigns ( Table 2).…”

“…In general, the profile of each investigated urban microclimate is determined by the unique characteristics of the corresponding area. Therefore, urban microclimate and its intrinsic disomogeneity needs to be in-depth investigated together with its causes and effects with respect to the spatial and temporal variations originated from the specific local morphology, anthropogenic action, urban planning and temporal weather conditions [32][33][34]. Therefore, for precisely determining the gradient and the inner-city deviations of microclimatic variables, their spatial extent needs to be thoroughly delineated.…”

Monitoring microclimate variables within cities with high accuracy is anongoing challenge for a better urban resilience to climate change. Assessingthe intra-urban characteristics of a city is of vital importance for ensuringfine living standards for citizens. Here, a novel mobile microclimate stationis applied for monitoring the main microclimatic variables regulating urbanenvironment as well as directionally monitoring shortwave radiation and illuminance and hence evaluate the effect of urban surfaces and anthropogenicheat. We performed day-time and evening-time monitoring campaigns withina historical city in Italy, characterized by substantial urban structure differentiations. We found significant intra-urban variations concerning variables suchas air temperature and shortwave radiation. Moreover, the proposed experimental framework may capture, for the very first time, significant directionalvariations with respect to Shortwave radiation and illuminance across the cityat microclimate scale. The presented mobile station represents therefore thekey missing piece for exhaustively identifying urban environmental qualityand data driven modelling toward risk and resilience planning. It can betherefore used in combination with satellite data, stable weather station orother mobile stations, e.g. bicycle and wearable sensing techniques, througha citizens’ science approach in smart, livable, and sustainable cities in the near future.

“…The present work proposes a bottom-up process to detect local urban microclimate conditions based on collected experimental data. The main environmental parameters are monitored by means of a miniaturized wearable weather station which can be easily warren by a pedestrian (Pigliautile and Pisello, 2018). Therefore, the perspective of the monitoring campaign is human centred, and the collected data represent what citizens are subject to, in terms of environmental forcing, air quality, and thermal overheating/overcooling.…”

The rapid urbanization of the last century coupled with local climate change imputable to anthropogenic actions triggered a huge research effort aimed at investigating urban microclimate. Typically, cities present a variety of microclimates due to the internal variation of their landscapes in terms of morphology, surfaces properties, presence of greenery, etc. Location-specific microclimate conditions affect both (i) building energy needs and (ii) citizens' quality of life. For these reasons, a small-scale analysis from the citizen perspective with high-time-resolution environmental data is required. Recent studies tried to reach that level of precision by using remote sensing, movable observational transects or dense network of weather stations located in specific points of the urban settlement. Within this framework, the current study presents a new bottom-up methodology which aims at identifying granular microclimates within the same built environment. The method consists of a cluster analysis of experimental data collected by a wearable miniaturized weather station which allows the monitoring of outdoor parameters at the pedestrian height and with high-time resolution. Experimental campaigns were conducted in five different case studies, where a planned monitoring path was repeated at different times during the day. The heterogeneity of the context demonstrates the replicability of the proposed method, suitable for clustering different areas of a same urban context characterized by variable local microclimate. The study contributes to better understand the variability of building boundary conditions for energy need prediction and indoor/outdoor environmental comfort assessment.
