THE EFFICIENCY OF CELLULOSE - GREEN MATERIALS AND TECHNOLOGY USED IN THERMAL INSULATION FOR SAVING ENERGY IN NZEB BUILDINGS

Abstract

This research presents the advantages of using cellulose - green materials in thermal insulations for saving energy for future buildings. These advantages are involved in massive reducing thermal losses in the roofs, specially for non easy accessable zones from the lofts and small height of attics. The method proposed ist o be performed the analysis of mass and heat transfer through walls with thermal insulation materials of vegetal origin like cellulose. There is analysed the condense accumulation in the outer walls under the conditions of a location in the Romanian climatic zone III for a residential building and in addition a case study for a building from the Romanian climatic zone II also a residential building. The nZEB buildings built with green materials and technology will respond to rising the efficiency of building heating/cooling energy consumptions, will have a proper diffusion capacity, so will not influence the release of moisture and will lead in raise the sustainability of these homes. The main result of this study proved that the proposed green material is an efficient high-performance thermal insulator compared to the thermal insulation used on the scale wide and prevents condensation. The conclusions of this study can be used in projecting nZEB buildings with green technologies in order to achieve the energy efficiency and internal comfort conditions performances.
