ANALYSIS OF THE ENVIRONMENTAL IMPACT OF CONSTRUCTION BY ASSESSING THE CARBON FOOTPRINT OF BUILDINGS

The paper presents a methodology for carbon footprint assessment of buildings according to the current European standard. The analytical formulas are proposed to assess the carbon footprint through emissions calculation for the building life cycle including extraction, transportation, and processing of raw materials, construction and installation process, operation, maintenance, and repair, as well as liquidation and disposal. Beyond the life cycle boundaries, the possible benefits from recycling and reuse of building components and materials are considered.

The main stages of the life cycle of the formation of student communities of universities

Virtual communities become an extremely popular phenomenon, and every day their number becomes larger, develop existing community. Rapid development gain communities formed around universities. Mainly this is the student community, designed for the exchange of abstracts, of course, information about organization of educational process, reviews about the teachers. Unfortunately, less community representation of the university on the Internet.

Техніко-економічні показники низькоенергетичних будинків

In this paper the technical and economical parameters of buildings on the bases of their energetic and ecological analysis are shown. The economy effectiveness of investment project by the criterion of minimizing operating costs of buildings and term return on investment is assessment by mathematical modeling method.

Аналіз систем утеплення будівель з врахуванням життєвого циклу теплової ізоляції

Each increase of energy tariffs actualizes the problem of insulation of buildings in order to reduce heating costs. This raises the question of choice of insulating material. In the article is considered the actual question comparing the most common types of thermal insulation - polystyrene (foam) and mineral wool. As a general criterion of comparison proposed life cycle assessment which is formed of four stages assessments existence of material: manufacture, installation, use (operation) and return back to the environment.
