Abstract
The article focuses on highlighting the role of life cycle costing (LCC) in the preparatory and implementation phase of residential projects. It involves the evaluation of several investment scenarios in the pre-investment phase, the choice between variants of the design of the entire building or its parts, and the choice of variants of structures and equipment with acceptable parameters. An innovative method of evaluating the life cycle of buildings is described in the article. This method was tested in selected residential projects realized by Skanska in the Czech Republic. Experience from construction practice shows that the choice of variants, constructions, or equipment of buildings only on the basis of the lowest acquisition costs (lowest bid prices) is wrong. The LCC calculation tool has been designed to model life cycle costs of individual variants of construction designs with different input parameters. It is possible to analyze the components or equipment that have the greatest impact on total life cycle costs. The article presents a tool that evaluates the long-term economic efficiency of the proposed residential buildings in terms of analysis of life cycle costs. The article will also expand the knowledge of the professional and general public about the importance of examining investment and operating costs already in the phase of construction preparation.
Highlights
Life cycle costing should be undertaken for each construction project
The paper investigated the potential role of life cycle costs (LCC) calculations in planning, construction, and operation phases of residential development projects
The paper tested the impact of five variants of heating and hot water preparation on life cycle costs (LCC)
Summary
The article deals with the description of the innovative method and LCC calculation tool for evaluation of construction’s life cycle costs (LCC). Life cycle costing and analysis are primarily a tool for informed decisions. The analysis is important in finding the best solution when the environmental and long-term sustainability aspects are taken into account. Life cycle assessment of investment residential projects is part of the building quality assessment system. Life cycle costing should be undertaken for each construction project (residential buildings, industrial buildings, transport infrastructure, etc.)
