Mineral fiber products are the most common group of thermal insulations currently in use. Heat transfer in these materials has been the subject of extensive investigations thanks to their numerous and varied applications as building and industrial insulations. Early studies addressed the problem of energy transport in terms of a simple theoretical model. They showed…
Energy efficiency is coming to the forefront in the architecture, as, apart from the significance of a reduced environmental impact and increased comfort for users, the current energy crisis and economic recession has bumped up the importance of the financial cost of energy. Since the Kyoto Protocol was signed in 1997, governments all over the…
The European Directive 2010/31/EU states that the measures to improve the energy performance of new and existing buildings should take into account climatic and local conditions as well as indoor climate environment giving the priority to the summer period. The Directive introduces the concept of thermal capacity that is very important in temperate climates during…
The house is not only a roof, but also a home, the place where it is formed the moral climate and on which lasts the family spirit. UN has classified habitat settlements and identified 10 general functions that every habitat should have. (Recreations and interpretation, Preparing the foods, Eating, Relaxing and Sleeping, Study ,WC, Hygienic…
Insulation is a vital part of all contemporary buildings; it performs many functions, all of which influence the cost of the building and its operating cost. This component is essential to be positioned not only in the floors, walls, and ceilings of the buildings, but also using of other key technique to improve the insulating…
Heat transfer, any or all of several kinds of phenomena, considered as mechanisms, that convey energy and entropy from one location to another. The specific mechanisms are usually referred to as convection, thermal radiation, and conduction . Conduction involves transfer of energy and entropy between adjacent molecules, usually a slow process. Convection involves movement of a heated fluid, such as air, usually a fairly rapid process. Radiation refers to the transmission of…
