Residential Construction with a Focus on Evaluation of the Life Cycle of Buildings

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.

Impact of Regional integration on Trade and Economic Cooperation – a key study of Georgia and Azerbaijan

“…In this regards Georgia faces the challenge in ensuring stability of institutions, one of the primary factors influencing FDI (Cermakova, 2020) and trade (Ouechtati, 2020) in general. The comparative advantage of Georgia in this regards consists also in availability of real estates, representing, apart from wafe level (Jasova, 2016) another prerequisite for FDI inflow, as confirmed by Hromada et al, 2021. Foreign direct investment causes an increase in the costs associated with housing, whether it is owner-occupied housing or rental housing (Horak et al, 2021). Foreign direct investment then causes an increase in property and income inequality between individual regions (Machova et al, 2022), so creating a stable and balanced growth oriented economic environment is crutial for all economies under any kind of economic integration and closer cooperation.…”

Comparison of the Embodied Carbon Emissions and Direct Construction Costs for Modular and Conventional Residential Buildings in South Korea

“…In the construction sector, the life cycle cost (LCC) is a method used to analyze the overall cost of a construction project [68][69][70]. The costs of design, construction, maintenance, and disposal are all considered in this calculation [71][72][73], which is used by project stakeholders to assess the economic feasibility of construction projects and select the optimal alternatives. For example, a project's high initial construction cost might be justified by the subsequent lower maintenance costs of the building based on a customized cost list for the project developed during the life cycle cost analysis [2,72].…”

Change in the Affordability of Owner-Occupied Housing in the Context of Rising Energy Prices

“…Rising energy prices are reflected not only in the cost of energy consumption in households, but also in the prices of building materials and construction work [16]. Construction is a sector that consumes a significant amount of energy produced as quantified by Schneiderova-Heralova [17] or Karasek [18] thus energy prices create pressures at the supply side of property market [19]. Housing and energy poverty are two sides of the same issue, increasingly reflected in research papers and expert analyses.…”
