IMPLEMENTING BUILDING INFORMATION MODELING IN RETROFITTING OF BUILDING PROJECTS AND ENERGY EFFICIENT CONSTRUCTION

Abstract

Nowadays building projects have been encouraged to adopt green and sustainable construction strategies as the construction sector is responsible for using 42 % of the world’s energy, 30 % of its raw materials, and 25 % of its fresh water. The priority purpose is not only to upgrade and enhance projects of existing buildings, the target is also to reevaluate the approach of the whole construction sector [1]. The issue requires complex and modern methods which should include retrofitting as well as reconstruction of existing infrastructure. The housing fund of Ukraine as well as other European countries calls for alterations which will lead to gaining and raising its energy efficiency. To create the optimum alternatives there should be conducted an investigation of the possibilities of changing the real estate’s usage. A framework for value engineering and building information modeling, especially appropriate for existing buildings, is required to aid decision-makers in selecting the best options for current building utilization.
