Effective Thermal Insulation: The Operative Factor of a Passive Building Model

Thermal insulation is the reduction of heat transfer between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. In low-energy buildings in climates with a heating demand the entire building envelope has to be well insulated. The building envelope consists of all the building elements which separate the inside from the outside. Its main purpose is to provide for a comfortable indoor climate irrespective of the outdoor climate which is determined by the weather. During cold periods the temperature inside the building envelope is usually higher than it is outside. As a result, heat is lost through the envelope and, unless this heat is replaced, the inside of the building cools down adjusting to the outdoor temperature. The inverse applies during hot periods with excessive heat entering the building through its envelope. Therefore, it makes sense to restrict the heat flow in any building irrespective of the climate and this is where thermal protection comes in. Effective Thermal Insulation - The Operative Factor of a Passive Building Model presents elementary practical and well-organized applications in saving energy concept, along with a solitary action for this category of topics. The book aims to illustrate numerous methods in treatment, the concept of thermal insulation such as processes and the attempt to build an efficient passive building model.
