273 | P a g eTHE USE OF NATURAL RENEWABLE MATERIALS IN THE SUPPORT OF SUSTAINABLE DEVELOPMENT

Architecture design today has become far more challenging then it traditionally used to be. On top of accustomed thermal insulation thickness and heating demand, architects need to design new or renovate existing structures in compliance with the primary energy demand, CO2 reductions, as well as ecological properties of the building materials. These properties are essential for a holistic assessment. Researches and demand for ecological building materials have been growing dramatically, particularly for insulating materials from renewable resources. Conventional design, constructions and conventional materials are still predominantly used in the world, particularly in BiH and Turkey. The aim of this paper is to present a comparison between the use of conventional methods, constructions and materials against alternative solutions of renewable insulations materials application in the wall constructions. The conventional walls are predominantly made of cement, bricks, Styrofoam, plaster and paint. For the innovative walls, materials used for a wall 1 are: brick, wood fibre insulation, plaster, coat render, and for wall 2: timber, sheep’s wool insulation, brick, OSB board and plaster. The tests results indicate the amount of primary energy and CO2 emission which could be saved if renewable materials are used not only for insulation but for the construction as well. Findings also show great demand for a new clean technology in brick production that will save energy and CO2 emission. Additionally, renewable materials have more ecological and fewer health damaging aspects. Keywords: wall construction, natural insulation materials, primary energy, global warming potential, health
