PurposeThe modular dynamic façade (MDF) concept could be an approach in a comfort-centric design through proper integration with energy-efficient buildings. This study focuses on obtaining and/or calculating an efficient angle of the MDF, which would lead to the optimum performance in daylight availability and energy consumption in a single south-faced official space located in the hot-arid climate of Yazd, Iran.Design/methodology/approachThe methodology consists of three fundamental parts: (1) based on previous related studies, a diamond-based dynamic skin façade was applied to a south-faced office building in a hot-arid climate; (2) the daylighting and energy performance of the model were simulated annually; and (3) the data obtained from the simulation were compared to reach the optimum angle of the MDF.FindingsThe results showed that when the angle of the MDF openings was set at 30°, it could decrease energy consumption by 41.32% annually, while daylight simulation pointed that the space experienced the minimum possible glare at this angle. Therefore, the angle of 30° was established as the optimum angle, which could be the basis for future investment in responsive building envelopes.Originality/valueThis angular study simultaneously assesses the daylight availability, visual comfort and energy consumption on a MDF in a hot-arid climate.

<p>La producción de hortalizas en la región Noroeste de México es una actividad económica relevante, lo cual se atribuye a factores naturales como el clima, calidad de los suelos y la cercanía al mercado de Estados Unidos de Norteamérica. Es evidente la creación de ventajas competitivas mediante la diferenciación del producto, por su calidad, a través de la aplicación de normas. La adopción de estándares es una práctica generalizada, sin embargo no está cuantificado el rol de las instituciones en estos procesos y su contribución a aumentar o inhibir los niveles de adopción de los mismos. El objetivo de este trabajo es analizar los factores que mas influyen en la implementación de grados y estándares en el sector hortícola en la región noroeste de México. Para la medición de la adopción se utilizó un modelo logit que permite determinar el efecto de las variables del entorno microeconómico que incide en la adopción de estándares. Se concluye que los cambios en los sistemas de producción mediante la aplicación de buenas prácticas agrícolas y las organizaciones de productores con actividades de capacitación, seguimiento y acompañamiento son lo que han contribuido en mayor forma al proceso de adopción de estándares por parte de las empresas productoras de hortalizas.</p><p> </p><p><strong>Determinants of the adoption of standards in the horticulture subsector of Northwestern Mexico.</strong></p><p>Vegetable production in the northwestern region of Mexico is an important economic activity; this is attributed to natural factors such as climate, soil quality, and proximity to the U.S. market. Clearly, the creation of competitive advantages gained by product differentiation, while maintaining quality, is extremely important and can be achieved through the application of standards. The adoption of standards is widespread; however, the role of institutions in these processes and their contribution to enhancing or inhibiting levels of implementation has not yet been quantified. The aim of this paper is to analyze the factors that most influence the execution of grades and standards in the horticultural industry in the northwest region of Mexico. Implementation levels were measured using a logit model that determined the effect of microenvironmental variables on them. The paper concludes that changes in production systems through the application of good agricultural practices and changes in organizations through training, monitoring, and support are what have helped companies that produce vegetables adopt and implement more standards.</p>
