“…In previous work, 41 the Mean Insolation Factor (MIF) indicator has been defined. The Mean Insolation Factor (MIF) provides a measure of the potentially collecting north facing walls, not masked by neighboring buildings and trees, calculated as: the ratio of the sum of insolated collecting areas of north facing walls, times the sum of the energy received at each considered hour, during a heating season, to the sum of the total areas of the same surfaces, free of all masking, times the sum of the hourly impinging radiation during the considered heating season, as a percentage.…”

The study proposes determining the potential of solar collection in urban environments, considering urban building different morphological variables corresponding to representative urban settings in the Mendoza Metropolitan Area (AMM), Argentina.The methodology involves monitoring the global solar irradiance on the vertical plane in north facades, completely and partly sunny, affected by solid masking and masking woodland.Results obtained so far indicate that solar masking is critical for vertical surfaces, with a reduction of the available solar energy between 2% and 66% in the winter season, depending on the type of trees and the building morphology. In the summer season, the measured solar masking values range from a maximum of 83% and a minimum of 10% influence of surface shaded by the neighboring buildings and trees. The results demonstrate the impact of the main variables that determine access to the sun in an urban environment (Urban Tree Canopy, Building Morphology, Building Height, Urban Street Width)The study will allow for future reform and progressive updating of urban and building codes to implement higher levels of energy efficiency and minimum environmental impact by urban buildings, considering the principal urban building variables.

Determinación de densidades urbanas sostenibles en base a metodología relativa al acceso solar: caso área metropolitana de Mendoza, ArgentinaDetermination of sustainable urban densities based on a methodology related to solar access: study case of the metropolitan area of Mendoza, Argentina No obstante, los niveles poblacionales no son únicos y estándares, sino que deben encontrarse en relación con las características propias de cada sector. Este trabajo tiene como objetivo principal desarrollar una metodología de cálculo que permita determinar niveles poblacionales máximos contemplando los requerimientos bioclimáticos de la ciudad y garantizando el acceso al sol más igualitario para todos los habitantes de la urbe. La misma es aplicada en el Área Metropolita de Mendoza y denota que las dimensiones de las manzanas y el ancho de las calles limitan la capacidad constructiva del sector y, en consecuencia, la cantidad de personas albergable. Los resultados obtenidos dan cuenta de las densidades poblaciones máximas para los distintos sectores, las que varían entre los 49 y 400 habitantes por hectárea, siendo las manzanas angostas con calles estrechas las de menor capacidad.Palabras clave: acceso al sol, densidad poblacional, indicadores urbanos, urbanismo bioclimático. AbstractOne of the current challenges in terms of design and urban planning involves the transformation of existing cities in models of cities that take care of the environment and improve the quality of life of the inhabitants. Studies indicate that clusters of low population density are the most polluting, (Cepeda y Mardaras, 2004; Norman, Maclean, Asce & Kennedy, 2006) consequently urban densification is one improvement to promote. However, population levels are not unique and standard, but must be found in relation to the characteristics of each urban area. This work has as main objective to develop a methodology of calculation to determine maximum population levels considering the bioclimatic requirements of the city and ensuring more equitable access to sunlight for all the inhabitants of the city. The same is applied in the Metropolitan Area of Mendoza and denotes that the dimensions of the blocks and the width of the streets limit the constructive capacity of the sector and consequently the number of people accommodating. The results obtained indicate that the maximum population densities for the different sectors vary between 49 and 400 inhabitants per hectare, with narrow blocks with narrow streets being the ones with the lowest capacity.

“…In this way, a probable energy yield can be effectively calculated based on the reliability of the data obtained and the correct evaluation of the parameters used in the simulations. Zhang et al reviewed the state-of-the-art technologies for evaluating the reliability of large-scale PV systems [27]; on the other hand, Arboit et al assessed the solar potential of low-density urban environments [28,29]. Salazar and Raichijk studied the assessment of cloud conditions for determining the characteristics of solar resource availability and proposed a way to predict the actual cloud status in high altitude sites [30].…”

The use of renewable energies requires a precise and detailed quantification of the resource available. Because of the cost of solar stations or limited availability of skilled human resources, in most emerging countries, this assessment is made only on a few points scattered over large areas. We report here a simple and inexpensive method to evaluate the photovoltaic (PV) potential for a specific geographic region and a given PV capture technology. The system allows for a direct evaluation of the energy actually obtainable by scaling the measurement array of photovoltaic cells. The proposed measurement system can be installed as a stand-alone unit, or as part of a measurement network, connected to a more sophisticated central hub. The measurement station consists of said PV array (or similar PV array), a resistor, and a portable data logger. The system is calibrated with a device composed of a small array of PV cells, a resistor load bank, and two multimeters. Due to its low cost, this system can be replicated as many times as required with minimal investment. This would make it possible to evaluate the available photovoltaic potential of large regions with accurate and detailed data. Measurements carried out in Buenos Aires and in Antarctica confirm the consistency of the method.
