El diseño de las condiciones de iluminación natural sigue siendo hoy en día una tarea complicada debido a la gran cantidad de variables que intervienen en las mismas, que, además, dependen de las decisiones de diseño del proyecto arquitectónico, sobre el que también intervienen otros muchos factores para llegar a la definición formal y material...

En la iluminación natural de un espacio intervienen tres factores fundamentales: la fuente emisora de luz, el espacio receptor y las características de los elementos que filtran la luz: los huecos. En los edificios patrimoniales se conoce la fuente emisora y las características espaciales del receptor. De lo que no se tiene conocimiento es de...

In order to compare the domestic hot water heating (DHW) and the power supply performances of a south-facing unglazed flat-plate PVT installed on a roof, with an 8º gradient belonging to a solar house located in Madrid (40.24N, 3.41O) with no surrounding obstacles, a finite element heat flux simulation was performed and contrasted with a...

In recent years, the building sector has been turning towards intervening in the existing city building stock. In fact, it is generally accepted that the refurbishment of buildings based on sustainability must form the axis of reformulation of the building sector. Although energy refurbishment is commonly accepted and recommended towards...

In recent years, the building sector has been turning towards intervening in the existing city building stock. In fact, it is generally accepted that the refurbishment of buildings and the urban regeneration based on sustainability must form the axis of reformulation of the building sector. Nowadays, achieving sustainable urban development...

Usually the effect of global solar radiation on buildings is evaluated by focusing on the visible part of its spectrum, namely daylight, or on the thermal equivalent of sunlight, solar heat gains through external windows. At present, due to the difficulty of integrating and comparing thermal and daylighting results, approaches considering the...

Tras la crisis energética de 1973 se ha incrementado exponencialmente el control de las condiciones higrotérmicas de la edificación, desarrollándose nuevas tecnologías para obtener una mayor eficiencia energética en los edificios, incluyendo la iluminación artificial. Así como un adecuado acondicionamiento térmico permite reducir el consumo...

Las cuestiones relativas al soleamiento e iluminación natural y su afección al diseño de los edificios ha sido objeto de pocas investigaciones y contadas aplicaciones prácticas, entre otras cosas, por la ausencia de requerimientos específicos mínimos a nivel nacional o local expresados mediante los correspondientes documentos normativos. Si...

The need for construction and restoration of buildings within an ecological and sustainable manner is highlighted in this increasingly aware global world; so it is very easy to fail thinking on how simple it could be to execute certain eco-efficient constructive proposal in any project, no matter its size. Despite having previous experiences in...

This paper analyses the influence of different perforated solar screens (PSS) in annual daylight conditions expressed using climate-based daylight metrics. The PSS design require parametric studies that are often complex and time consuming due to a large number of simulations. Hence, a new methodology is proposed to optimize PSS design by...

The main aim of this article is to determine suitable proportions for lightscoop skylights, whose main characteristic is a vertical opening oriented in the opposite direction to the solar trajectory, with a view to ensuring maximum illuminance on the area under study within a room. Lightscape 3.2 software was used to carry out the simulations,...

This work evaluates the potential for the reduction of energy demand in residential buildings by acting on the exterior envelope, both in newly constructed buildings and in the retrofitting of existing stock. It focuses on analysing social housing buildings in Mediterranean areas and on quantifying the scope of that reduction in the application...

The Passive House Standard is based on the reduction of energy demand and consumption. In Spain, this Passive House concept has become the preferred alternative for achieving nearly Zero Energy Buildings. The necessary criteria were incorporated into Spain's 2019 Technical Building Code, which considers the passive design of buildings. In fact,...

During the first stages of building design, issues like local climate or surrounding buildings are determinant. Also the configuration of every space depends on its orientation due to solar access, among others. The impact of these boundaries conditions on daylight illuminances in an open-plan office space is studied in terms of Daylight Factor...

The main aim of this article is to analyze the precision of several lighting simulation programs regularly used in daylighting studies for architecture, following the methodology established in the CIE test cases document. The 3DS Max Design 2014, Daylight Visualizer 2.6, DaySim 3.1b, Design Builder 3.0, Dialux 4.8, Ecotect Analysis 2011,...

Office buildings consume large amounts of energy and are responsible for a large part of greenhouse gas emissions worldwide. Among building energy efficiency measures, solar shading plays a significant role in reducing building cooling energy consumption. This study analysed the influence of solar protection on daylighting of an open-plan...
