Con el objetivo de analizar el efecto del clima y su modificación a causa del entorno urbano, se han desarrollado, para la presente tesis, diferentes modelos para cada uno de los mecanismos de transferencia de calor en la epidermis edificatoria. Estos modelos han sido acoplados entre si e implementados en herramientas informáticas y han sido...

Our present standard of living depends strongly on energy sources, with buildings being a primary focus when it comes to reducing energy consumption due to their large contribution, especially in tertiary buildings. The goal of the present study is to evaluate the performance of two different designs of hybrid systems, composed of natural gas...

The Urban Heat Island phenomenon is an increasingly important global issue. Understanding the physical characteristics of cities is critical, which is why many studies based on mobile measurements are currently being developed. However, it is highly challenging to compare them due to the various methods that are employed. Therefore, the present...

Las razones del rendimiento inferior de muchos de los edificios actuales y sus sistemas energéticos relacionados son diversas y estas son en una parte importante causada por una atención insuficiente a la influencia del comportamiento de los ocupantes. En los edificios inteligentes es necesario implementar nuevas oportunidades para integrar el...

PHDC, es un proyecto internacional, creado con el objetivo de promover el uso de sistemas de refrigeración Pasivos e Híbridos en los edificios entre profesionales de diseño, constructores, propietarios y usuarios. En este artículo, se describen brevemente algunos de los sistemas PHDC. En el marco de este proyecto, el trabajo de investigación...

La ventilación natural se ha ganado protagonismo en los últimos tiempos como una medida de ahorro de energía para edificios. Los dos principios fundamentales de ventilación natural son el tiro natural por diferencia de temperatura, y la fuerza del viento. El artículo pretende analizar la aerodinámica de los captadores y extractores de viento...

Driven by global climate objectives, the pursuit for eco-friendly refrigeration solutions has catalysed impressive advancements in the sector. Ammonia, a historically utilized refrigerant, is now widely adopted in light industrial applications, largely due to the growth of Ultra-Low Charge package chillers. Opportunities, however, persist for...

Buildings are known to be responsible for about a third of energy consumption in developed countries. This situation, together with the fact that the existing building stock is being renovated at a very slow pace, makes it crucial to focus on the energy retrofitting of buildings as the only way to reduce their contribution to these energy...

The reduction of energy consumption in the residential sector presents substantial potential through the implementation of energy e ciency improvement measures. Current trends involve the use of simulation tools which obtain the buildings' energy performance to support the development of possible solutions to help reduce energy consumption....

As microclimate modifiers, courtyards may be a good passive strategy for enhancing thermal comfort and reducing the energy demands of buildings. Thus, it is necessary to be able to quantify their tempering effect in dominant summer climates. This is frequently done using calculation methods based on CFD, but these have the drawback of their...

At present, the energy used for air conditioning in buildings in urban areas accounts for over 36% of total global energy consumption. Energy efficiency has become a critical factor in the urban planning of cities worldwide. Courtyard buildings in hot cities are a prime example of the approach used in traditional vernacular architecture to...

The 2030 climate and energy framework includes EU-wide targets and policy objectives for the period 2021–2030 of (1) at least 55% cuts in greenhouse gas emissions (from 1990 levels); (2) at least 32% share for renewable energy; and (3) at least 32.5% improvement in energy efficiency. In this context, the methodology of the cost-optimal level...

Sustainable passive design strategies can reduce the energy consumption of buildings. In this regard, inner courtyards act as microclimate modifiers that enhance the perception of comfort in the surrounding environment. The present study, through a pooled analysis of experimental and numerical data, intends to assess the beneficial effect that...

El patio es un elemento característico de la arquitectura tradicional mediterránea, en el que se consigue crear unas buenas condiciones microclimáticas, especialmente en verano, que son bien aprovechadas por el edificio al que pertenece. Se consigue, de esta forma, reducir las necesidades energéticas de acondicionamiento del edificio, y al...
