“…As previously stated, a major contributor to a neighborhood's life cycle impacts is the operational energy uses of buildings, which can be largely influenced by the building's urban environment. Srebric et al [43] proposes a review of the building neighborhood properties influencing the energy and airflows. The authors stress the fact that energy consumption patterns are highly dependent on the surrounding urban neighborhood.…”

“…This effect is favourable during both winter and summer [1], and is more significant in the latter. In fact, there is a relationship between urban geometry, specifically in the layout and proportion of full and empty volumes and the distribution of urban heat islands in cities [2].…”

“…Cities and towns are warmer at night than rural areas due to the absorption of solar radiation by the urban pavements and buildings. Urban morphology parameters, such as urban plan area density, geometry of the buildings and topographical features influence airflows in and around buildings and energy consumption on a regional scale [2,3]. In the same line, Jurelionis and Bouris [4] applied computational fluid dynamics methods in order to calculate surface pressure distributions on building surfaces for three city models and two wind directions.…”

This study identifies and proposes A GIS-based exploration of the relationships between aspect ratio of inner courtyards, porosity of the urban fabric and the climatic factors where it is located. To perform that comparison, morphological and measurement methods have been used to delineate spatial boundaries of urban densification. This methodology has been applied to a case study in Spain, where regulation establishes several climatic zones. Examples of cities in these zones have been examined to establish possible correlations. This paper analyses the particularities of these different urban scenarios, considering the effects of climate on the real urban densification. The purpose of this study is to find a relationship between the historical inner courtyards dimensions and the climate of the zone where they are located. In order to frame the real thermal behaviour of the inner courtyard in the context of the vernacular typologies studied, a representative sample of inner courtyards has been selected. The monitoring data presented allow quantifying the courtyard's ability to temper the maximum temperature values.

“…Urban morphology parameters, such as urban plan area density, frontal area density, geometry of the buildings, and topographical features influence airflows in and around buildings and, ultimately, energy consumption on a regional scale [1,2]. Airflow patterns in urban areas, referred further as neighborhoods, are especially important for buildings with natural or hybrid ventilation.…”

“…Airflow patterns in urban areas, referred further as neighborhoods, are especially important for buildings with natural or hybrid ventilation. However, air infiltration, urban heat island formation and airborne pollutant accumulation can affect air quality (IAQ) on the neighborhood or building scale, the coefficient of performance (COP) of heating, ventilation and air conditioning (HVAC) systems, and the heating and cooling demand of mechanically ventilated buildings as well [1]. Spatial arrangement of the neighborhoods influences energy transfer via convection, infiltration and conduction.…”

External air movement within built neighborhoods is highly dependent on the morphological parameters of buildings and surroundings, including building height and street cavity ratios. In this paper, computational fluid dynamics (CFD) methods were applied to calculate surface pressure distributions on building surfaces for three city models and two wind directions. Pressure differences and air change rates were derived in order to predict the heating load required to cover heat losses caused by air infiltration. The models were based on typical urban layouts for three cities, and were designed of approximately equal built volumes and equal air permeability parameters. Simulations of the three analyzed building layouts resulted in up to 41% differences in air change rates and heat losses caused by air infiltration. In the present study, wind direction did not have a significant impact on the relative difference between the models, however sideward wind direction caused higher air change rates and heat losses for all simulated layouts.
