Abstract

espanolLas ciudades modifican los parametros microclimaticos aumentando el calentamiento urbano; en virtud de ello, existen diversas estrategias que colaboran a disminuir este impacto en contextos aridos. El presente trabajo evalua el nivel de eficacia de dos estrategias factibles de ser incorporadas. Para ello, se disenaron 96 escenarios que combinan 2 alturas de edificacion (3 y 6m), 3 anchos de calle (16, 20 y 30m) y 4 orientaciones (E-O, N-S, NO-SE y NE-SO). Mediante el software ENVI-met se simulo el comportamiento termico de los escenarios propuestos, el modelo fue validado mediante el monitoreo microclimatico in situ. Las etapas de simulacion fueron: 1.morfologia, 2.forestacion, 3.albedo y 4.estrategias combinadas. Los hallazgos mas importantes indican que la incorporacion de las estrategias combinadas resulta ser la opcion mas eficaz ya que se potencian los beneficios individuales; alcanzando disminuciones de hasta un 12% en la temperatura maxima, 10% en la minima y 11% en la promedio. EnglishCities modify microclimatic parameters that increase urban warming. In regard to this, there are some strategies that contribute to the reduction of this impact in arid contexts. The present work evaluates the level of effectiveness of strategies that can be feasible incorporated. For this, 96 scenarios that combine 2 building heights (3 and 6m), 3 street widths (16, 20 and 30m) and 4 orientations (E-O, N-S, NO-SE and NE-SO) were designed. By using ENVI-met software, the thermal behavior of the proposed scenarios was simulated; the model was validated by in situ microclimatic monitoring. The simulation stages were: 1.morphology, 2.forestation, 3.albedo and 4.combined strategies. The most important findings indicate that the incorporation of combined strategies is the most effective option that maximizes the individual benefits; reaching decreases of up to 12% in the maximum temperature, 10% in the minimum and 11% in the average.

减少城市变暖策略的有效性。干旱气候城市的研究

西班牙城市通过增加城市供暖来改变微气候参数;因此，有几种策略可以帮助减少干旱环境中的这种影响。然而，在这种情况下，有必要考虑到这两种策略的有效性。为此，设计了96个场景，结合了2个建筑高度(3和6米)，3个街道宽度(16、20和30米)和4个方向(E-O、N-S、NO-SE和NE-SO)。利用ENVI-met软件模拟了提出的情景的热行为，并通过现场微气候监测验证了模型的有效性。模拟阶段为:1。morfologia、2。forestacion、3。反照率和4.组合策略。最重要的发现表明，合并联合策略是最有效的选择，因为它增强了个人利益;在最高温度下下降12%，在最低温度下下降10%，在平均温度下下降11%。英国城市修改微气候参数，增加城市变暖。在这方面，有一些战略有助于在干旱环境中减少这种影响。本工作评估可切实纳入的战略的效力水平。为此，设计了96个场景，结合2个建筑高度(3和6米)，3个街道宽度(16、20和30米)和4个方向(E-O、N-S、NO-SE和NE-SO)。通过使用envimet软件，对所提议情景的热行为进行了模拟;该模型通过原位微气候监测得到验证。= =地理= =根据美国人口普查，该镇的土地面积为。morphology、2。forestation、3。= =地理= =根据美国人口普查，该县的总面积为，其中土地和(3.064平方公里)水。最重要的调查结果表明，采用综合战略是使个人利益最大化的最有效选择;= =地理= =根据美国人口普查局的数据，该县总面积为，其中土地和(1.0%)水。
