“…However, it is also important that passive house technology results in significantly lower energy consumption, so operating costs when compared to conventional house are a lot lower and in the longer run bring the return on investment. Additionally, to assess the entirety of costs associated with constructing a passive house it is recommended to use life-cycle cost (LCC) methodology, which allows to select the most financially beneficial option [17,18]. Basing only on initiation investment cost may result in selecting the solution that will generate high operation cost in the long term [7].…”

Due to the changes in the energy standards for housing in Poland there are many concerns. Is the standard required by the regulation achievable and if it is, then at what cost? There are many solutions to construct a building in line with the requirements of passive house technology. They are differentiated by price and time required for implementation. This study is based on the solution proposed by one of Polish companies, offering technologically integrated products allowing, according to the producer, to build passive houses faster and easier. The goal of this study was to confront producer’s claim with reality by comparing time and cost of the same investment using conventional and passive house technology. The basis for time and cost analysis was a basic detached house design, partially modified with regards to materials and technology used. Conclusions of the study are based on the comparison of the two Gantt charts defined in Ms Project. Construction schedule was used to analyse the duration of both projects and the resources assignment was used in cost analysis.

“…The first examined criterion is the cost, which appears in each phase of a life-cycle of an object (LCC Life Cycle Cost), namely in the phase of the construction/completion, the usage and the damage [40,41]. The construction/completion of the anchoring system is a serious financial strain taking place in the initial phase of an investment process.…”

This paper indicates and analyses the use of anchoring systems, such as mooring piles, booms, mooring cables, and deadweight anchors with additional elastic connectors, which are the most frequently applied by the producers of floating houses. The selection of the most advantageous anchoring system is complicated and requires the application of quantitative and qualitative data and methods. This publication presents the results of the calculations using one of the most common methods of multi-criteria analysis of decision-making, namely AHP (analytic hierarchy process). The anchoring system, which is the most beneficial for users, has been indicated with the use of the main criteria such as: cost, time, external risk factors, geospatial factors, and the sub-criteria of the first and second order. Due to the conducted analysis, it has been shown that the most significant factor of the anchoring system selection for the users of floating houses is the investment cost that needs to be borne during the usage, and the most favourable anchoring system is the use of mooring cables.

The scope and frequency of conducting works related to the maintenance and use of road pavement are essential elements affecting their functionality and operating costs [3].…”

The cost of road pavement construction, its durability and reliability depends on many factors, including: the scope and detail of the technical design, quality of work but also the scope of works related to its maintenance, conservation and operation. Determining the amount of rational expenses, in terms of the life cycle cost of the pavement, requires determination and consideration of the above issues, already at the planning and design stage. In many cases, the ordering party analyzes only the initial investment costs, omitting the operating expenses for the pavement in the long term. The article points out the link between decisions taken at the planning and design stages and expenses incurred at the stage of maintenance and use of road pavement. The authors analyse and compare life cycle costs for two technologies of making road pavement-flexible (asphalt pavement) and rigid (portland cement concrete-PCC) and three categories of road traffic. Referring to the methodology included in [1], the authors present an example of the LCC analysis and determine the individual cost components: construction, renovation and maintenance during the period of 30 years. The analysed costs were determined based on the expert knowledge and current price publications. The authors draw attention to the fact that low costs incurred by the ordering party at the stage of investment implementation, in the course of use and maintenance of the pavement, entail significant expenses in the long-term. The authors also indicate difficulties related to the estimation of the cost of the road pavements life cycle. The main reasons include the lack of designers' knowledge about the technology of pavement repairs and related costs, as well as the lack of a simple model for calculating life cycle costs, which is a tool for supporting investment decisions and indicating the optimal solution already at the design stage.
