Reducing energy consumption in an existing shopping centre using natural ventilation

The energy consumption needed for establishing a good indoor climate in shopping centres is often very high due to high internal heat loads from lighting and equipment and from a high people density at certain time intervals. This heat surplus result in a need for cooling during most of the year, typically also during the winter, and often the needed cooling is provided by a mechanical ventilation system with integrated mechanical cooling.

Natural cooling in Hispano-Moslem religious architecture: the case study of the Mosque of Cordoba.

The Mosque of Cordoba is the best example of the Islamic religious buildings that survived in Spain. Its typology corresponds to a mosque of a large scale with the common plan of the early Muslim art. This model became an architectural reference for the mosques of Western Islam. The paper presents the results of measurements undertaken to assess the environmental performance of this building.

Natural cooling in Hispano-Moslem residential architecture: the case-study of the Court of the Lions and the Court of Comares in the Alhambra (Granada).

The XIV-century Palaces of the Lions and Comares constitute the principal residential complex of the Alhambra in Granada. Both are distributed around gardens enclosed in courtyards, originally with abundant vegetation and water. This paper includes a series of measurements carried out in the rooms and the courtyards in order to contrast the different microclimates, as well as some solar-penetration diagrams. It also focuses on the analysis of the Hispano-Moslem residential type in relation to ifs environmental performance

A novel concept of facade for daylighting and natural cooling.

The role of metallic surfaces is not only to save energy in winter and in summer by separating the inside and the outside. New and inexpensive ways of collecting solar energy for internal heating, new ways of ventilating, heating and cooling through the fabric elements are described. Two very significant prospects are : radiative cooling by metallic surfaces and enhancement of indirect daylighting by optimised ceilings. The subject of the European CURES program is to promote these new technologies by simulating and testing them.
