The paper presents the results of the measurements and integrated simulation of the energy demand and air exchange in one of the flats located in a 5-storey building located in urban area. The experiment was carried out during 3 weeks of March. The total energy consumption necessary for flat heating was measured continuously (at a 2 sec time step). After measurements were finished the energy demand and ventilating air flows were calculated assuming the same weather data variation as measured during the experiment, using the ESP-r software.
Several high schools in the south east of France are subject to a major work of renovation. These works need to take into account the problem of summer comfort for a better well-being and intellectual performance of students. One of it was chosen to carry a study on the specific constraints for achieving summer comfort. The study consists of surveys, monitoring and simulations. This enables to determine the major causes of the summer discomfort in field and to propose several passive solutions. These solutions were assessed by simulation using a dynamic simulation tool.
Local control of ventilation in large buildings is considered to be a main issue in energy savings regarding the huge energy losses that are usually induced by such large volumes. An efficient ventilation system and the development of local control ventilation strategies could prevent large buildings from having an unsuited or overvalued ventilation and reduce significantly the energy consumption.
La percepción del ambiente térmico no depende únicamente de los parámetros ambientales, sino que es un fenómeno que incluye muchos más factores del entorno interior y exterior, del sujeto que percibe estos parámetros. Incluso habría que considerar factore
Se analizan las posibilidades que se han visto tienen el empleo de los acumuladores de cambio de fase en la climatización, destacándose las ventajas que se han encontrado, tales como: la posible eliminación de las torres y condensadores evaporativos, por
Una fachada trasventilada es un sistema constituido por un elemento de aplacado o revestimiento exterior soportado por elementos portantes interiores, a travs de una subestructura, mediante fijaciones y anclajes, quedando entre aplacado y zona portante un espacio por el que puede discurrir una corriente de aire entre la parte inferior y la superior con objeto de mantener condiciones de baja humedad en el hueco, de forma que se preserven las condiciones idneas del aislamiento trmico incorporado.
There is a big concern for consequences of fire in parkings, especially those of public attendance and big dimension. Among Fire Protection means it is essential Smoke Control. This allows both people to escape safe from the fire and Fire Brigades to reach the fire in order to control it.In Spain there are not agreed or published calculation methods for smoke control purposes in the event of Fire. So, for this purpose they have been adopted calculation methods which have been though to ventilate and dilute gases produced by cars in normal activity.
Design requires the knowledge of what is to be achieved and how is wanted to be achieved. The final definition of a product is usually the result of a cycle of definitions and redefinitions, depending of an interactive and iterative process where many participants take part. Axiomatic Design is one of the latest design theories, which allows a structured decision process. According to Axiomatic Design, two axioms govern good design: the Independence and the Information Axioms.
Efficient ventilation of indoor environments shall guarantee not only a proper oxygen flow for human breathing, but also an effective removal of pollutants released by human metabolism and building materials. Usually, high ventilation rates are adopted to reach these two goals, with a consequent high energy consumption for buiding climatization.
The growing interest in Italy for the tutelage, the restoration and the valorisation of the historical-cultural resources and the necessity of a better conservation of the artworks of great value require that the museums be provided with appropriate HVAC systems for the control of the ambient conditions. The suitable microclimate for the conservation of the works inside a
museum can be identified by means of a multisubject investigation.
