DESIGN OF CONSUMER MODEL AND ENVIRONMENTAL ASSESSMENT OF USED BUILDING MATERIALS.

Environmentally friendly building materials and constructions are intended to reduce energy and material flows during the entire building life cycle. The evaluation is focused on the assessment of consumption and depletion of material resources, especially non-renewable resources, to minimize the life-cycle impact of materials on the environment and enhance the indoor environmental quality by concentrating on the evaluation of energy flows through the building constructions. Energy effective houses increase efficiency of sources utilization (energy, water and materials) and they are designed in order to decrease effect on human health and environment during their lifecycle by means of better location, design, constructions, operation, maintenance and reconstruction. The factor of performance is their main contribution what means lower energy consumption and lower operating costs too. The energy effective houses don't present the new definition of projection but it is more improving of attested processes and adaptation to new requests. These buildings have certain specifications in the sphere of the thermal-technical demands -- on external walls, roofs, ceilings above unheated space, ground floor, windows, doors -- in comparison with common development. Constructions that divide spaces with different indoor air temperatures must meet a lot of building-constructional and building-physical conditions. Constructions that divide spaces with different indoor air temperatures must meet a lot of building-constructional and building-physical conditions. These conditions will be solved by design of consumer model. The aim of this paper is design of consumer model and environmental assessment of used building materials focused on life cycle analysis.
