Application of Innovative Composite Cool Thermal Insulating Material for the Energy Upgrade of Buildings

摘要

The need to improve energy efficiency of existing buildings is more than understandable and compelling. It is expressed through the EU Directive 2002/91/EU concerning the energy performance of buildings, the Greek Law 3661/08 concerning the improvement of the energy performance of buildings;; which constitutes the harmonization of the Directive in the Greek legislation as well as the Regulation on Energy Efficiency Buildings (KENAK) which together with the Technical Instructions of the Technical Chamber of Greece, are the main application of the Legislation. The composite cool materials are a new and interesting solution for the constructions. Having identified-with extensive bibliographic research-the existing state of the market for thermal insulation materials and trends, these composite materials were characterized as a successful option. Finally, external thermal insulation composite systems were produced (with photocatalytic coating) and composite materials for the roof (extruded polystyrene with low reflectivity ceramic tile) which were analyzed-initially theoretically-in order to determine the energy performance of the building before and after their application, and then applied to an existing building. Additionally, there were determined the conditions before and after the installation of materials for thermal insulation capacity, by measuring the rate of heat transfer, by conducting measurements for the evaluation of the implementation of the new products of thermal comfort and air quality as well as by representative measurements of the microclimate of the area both during summer and winter. The results of the energy performance of new materials after their first application are to be presented
