The building industry represents huge consumer of sources and energy, heavy polluter and waste producer. The material and energy resources are limited with regard to current increasing population and affluence increase trends. The buildings during life cycle can make substantial contribution to energy and carbon conservation by sophisticated building approach. The environmental assessment of construction solutions by methodology life cycle assessment showed that using natural plant materials, which serve as long-term carbon store, ensure elimination of carbon footprint and energy consumption. The aim of multi-criteria analysis is to optimize the design of high environmentalperformance, energy effective and healthy constructions of green building.
