“…Vegetation structure plays an important role in modifying microclimatic conditions such as temperature, humidity and wind speed by acting as a buffer, which are all linked to adult mosquito survival and development [ 42 , 71 , 72 , 74 ]. Conversely, built-up structures, such as roads and buildings, also modify these microclimatic conditions, but then in the opposite direction, resulting in the urban heat island effect [ 75 ]. Indeed, our results show that parks were cooler and maintained higher relative humidity levels compared to residential areas, which is line with literature and promotes mosquito abundance based on their temperature preferences [ 74 – 77 ].…”

“…In parks, characterised by permeable soils and permanent water bodies, precipitation will either infiltrate into the soil or flow towards permanent water bodies before immature mosquitoes can emerge as adults. These permanent water bodies often contain an abundance of mosquito predators such as fish, amphibians and dragonfly larvae [ 72 – 75 ]. Even though we only sampled publicly accessible mosquito breeding habitats in the residential environment and all breeding habitats in the parks, we only visually observed larvae in residential areas in storm drains, which are a well-known habitat for Cx.…”

Background There is an urgent need for cities to become more climate resilient; one of the key strategies is to include more green spaces in the urban environment. Currently, there is a worry that increasing green spaces might increase mosquito nuisance. As such, this study explores a comprehensive understanding of how mosquitoes utilise contrasting grey and green habitats at different life stages and which environmental factors could drive these distributions. Methods We used a setup of six paired locations, park (green) vs. residential (grey) areas in a single model city (Leiden, The Netherlands), where we sampled the abundances of different mosquito life stages (eggs, larvae, adults) and the local microclimatic conditions. In this study, we focused on Culex pipiens s.l., which is the most common and abundant mosquito species in The Netherlands. Results Our results show that while Cx. pipiens ovipositioning rates (number of egg rafts) and larval life stages were far more abundant in residential areas, adults were more abundant in parks. These results coincide with differences in the number of suitable larval habitats (higher in residential areas) and differences in microclimatic conditions (more amenable in parks). Conclusions These findings suggest that Cx. pipiens dispersal may be considerably more important than previously thought, where adult Cx. pipiens seek out the most suitable habitat for survival and breeding success. Our findings can inform more targeted and efficient strategies to mitigate and reduce mosquito nuisance while urban green spaces are increased, which make cities more climate resilient.

“…The ENVI-met model is a prognostic microclimate model that has been specifically developed to simulate the complex interactions among surfaces, plants, and air within an urban setting [7]. The use of this method is prevalent in the estimation and evaluation of outdoor thermal comfort [8], [9] , as well as in the examination of the influence of the urban microclimate on building energy consumption [2], [10].…”

Despite the fact that the interrelationships between urban microclimates and energy demand have been recognised, there are not many processes that combine microclimatic boundary conditions to estimate energy consumption in parametric morphological investigations. Therefore, this paper will demonstrate a simple step-by-step methodology to incorporate the effect of urban microclimate on building cooling energy demand in semi-arid climatic areas. In this study, the combination of ENVI-met, Urban Weather Generator (UWG) and Rhino grasshopper are used to investigate the connection between microclimate and energy in the climatic environment of Kayseri. This coupling’s potential is investigated across compact high-rise, midrise and low-rise buildings, focusing on the cooling requirement on the hottest days. The comparative study shows how and to what extent urban geometry, building height in this case, contributes to modifying the magnitude of microclimate impact on building cooling performance.

“…Building and construction materials can affect albedo, thermal conductivity, and urban surface heat capacities, consequently impacting the amount of reflected energy [28]. Yang et al [29] pointed out the interest in studying urban microclimates and their impact on the built environment; they also stressed that urban heat islands (UHI) are among the most widely discussed topics in urban microclimates. In some cities, it has been estimated that between 5 and 10% of the electrical energy is used to mitigate the temperature increases caused by UHIs [30,31] since air conditioning equipment increases its workload during the summer, which leads to excessive electrical consumption [32,33].…”

Air Temperature Variations Due to Different Roofs and Their Impact on Energy Consumption and Emissions: Mexicali University Campus Case Study

Roof surfaces on which air conditioning equipment is installed cause significant air temperature increases around the condensers due to roof thermal properties, resulting in excess electrical energy consumption and greenhouse gas (GHG) emissions. An experiment to quantify such excesses during the summer was conducted at a university campus in Mexicali, Mexico. The air temperatures and surface temperatures for three types of roofs were recorded. Temperatures (condenser inlet air temperatures) were used as the input data to a priori estimate the electrical consumption of a 5-ton A/C equipment working over these different roofs. Temperatures recorded by a nearby meteorological station were used as a reference. The results indicate a differential of up to 4.81 °C, resulting in an excess of electricity consumption of 5.55 kWh and an additional 3.9 kg of CO2 emissions, representing an 8.2% energy surplus and differences of up to 2.1% in electricity consumption provoked by microclimate.
