Electric vehicles are a leading candidate in the clean energy market. This paper aims to analyse the feasibility of the deployment of electric buses (EB) based on the existing bus routes in Brunei, by the use of life cycle cost analysis and the analysis of the parameters that influence the overall life cycle cost. The findings from the study revealed that EB are significantly more expensive than diesel buses (DB), with their acquisition and maintenance costs contributing substantially to their overall life cycle cost. In order to promote EB deployment, the government needs to look simultaneously into providing subsidies for EB and imposing taxes on DB, the provision of charging infrastructure, and ensuring maintenance capability, as well as increasing the current subsidised diesel price. It was also shown that increasing the cost of diesel to the average US diesel price of USD$3.101/L, an initial subsidy of USD$67,586 towards the purchase of EB, and a tax of USD$67,586 for the purchase of DB would allow EB to compete in the market, with the amount of tax and subsidy being gradually reducible over time, as EB and battery technology becomes more mature. From an environmental perspective, the emissions from EB come out higher than the emissions from DB. The efficiency of electric power generation needs to be enhanced, and renewable energy sources and the adoption of carbon capture technology need to be explored in order to exploit the full benefit of EB and ensure more environmentally sustainable bus operation.

The idea of achieving energy security and lowering the dependence on the global hydrocarbon market is at the top of the agenda in many countries. Most of them consider switching from traditional energy sources to renewable ones as one of the ways to reduce fuel import. This concept absolutely conforms to one of the UN Sustainable Development Goals (Goal no. 7, “Affordable and Clean Energy”). In May 2019, the Government of Uzbekistan Republic adopted the law on the Use of Renewable Energy Sources (RES). By 2030, Uzbekistan is going to increase the share of RES in the total structure of electricity generation up to 25 % (currently it is at 10 %), by building solar and wind farms with a total installed capacity of 5,000 MW and 3,000 MW, respectively. The energy-deficient Bostanliq district of the Tashkent region has become one of the places of interest, where transport infrastructure, recreation services, and renewable energy will be developed. The purpose of this study was a multivariate analysis, considering the meteorological, ecological, and socio-economic characteristics of the Bostanliq district, leading to the selection of the optimal location for the wind farm. The assessment map based on the results of this analysis made it possible to identify areas that are most suitable for the location of wind power plants. The assessment method, that was used in this work, is also applicable to other regions of the world.

Energy storage providing auxiliary service at the user-side has broad prospects in support of national polices. Three auxiliary services are selected as the application scene for energy storage participating in demand management, peak shaving and demand response. Considering the time value of funds, the user-side energy storage economy model is built. The model comprehensively considers the delayed transformation income, the government subsidy income, the auxiliary service income and the whole-life-cycle cost factor. According to the cost and benefit analysis, an energy storage optimization configuration model is proposed. The model takes maximum revenue of industrial user in energy storage’s whole-life-cycle as the objective function. Then, the Cplex solver is employed to solve the model. In addition, four indexes are utilized to evaluate the financial effect brought by the user-side energy storage. Finally, the revenue and configuration results of the four types of battery energy storage are calculated to verify the validity of the proposed model. In comparison to the value of evaluation index, planning suggestions are provided for the user-side energy storage providing different auxiliary services. Moreover, the conditions of profit and worthwhile investment are obtained through sensitivity analysis of energy storage providing peak shaving service.

A comprehensive case study on life-cycle cost analysis (LCCA) was conducted on a two- story education building with a projected 40-year lifespan in College Park, Maryland. The aim of this paper was to (1) create a life cycle assessment model, using an education building to test the model, (2) compare the life cycle cost (LCC) of different renovation scenarios, taking into account added renewable energy resources to achieve the university’s overall carbon neutrality goal, and (3) verify the robustness of the LCC model by conducting sensitivity analysis and studying the influence of different variables. Nine renovation scenarios were constructed by combining six renovation techniques and three renewable energy resources. The LCCA results were then compared to understand the cost-effective relation between implementing energy reduction techniques and renewable energy sources. The results indicated that investing in energy-efficient retrofitting techniques was more cost-effective than investments in renewable energy sources in the long term. In the optimum scenario, renovation and renewable energy, when combined, produced close to a 90% reduction in the life cycle cost compared to the baseline. The payback period for the initial investment cost, including avoided electricity costs, varies from 1.4 to 4.1 years. This suggests that the initial investment in energy-efficient renovation is the primary factor in the LCC of an existing building.

During the project: Electric Hybrid Proton Exchange Membrane (PEM) Fuel Cell Transit Buses in China, the authors set up a model to calculate the life cycle cost of fuel cell bus (FCB). The model includes acquisition cost, fuel consumption cost and maintenance cost. In addition, the authors also take the government subsidies into account. After calculating, we see the cost of fuel cell is the most sensitive part of FCB life cycle cost. Using the model, we compared different bus life cycle costs. The result shows that FCB life cycle cost is 5 times more than the current diesel bus.

The analysis of the main provisions of two concepts: "The concept of application of construction information modeling in the management of the life cycle cost of public facilities" (Project) was developed at the National Academy of Public Administration under the President of Ukraine (NASU) by a group of experts led by Professor V.S. Kuybida and “Concept of Implementation of BIM - Construction Information Modeling in Ukraine” (Project) of the EU International Technical Assistance “Assistance to the Organization of the Government of Ukraine in Improving the Management of the Infrastructure Project Cycle”. The developers of the first Concept identified the principles, but the implementation of these principles in Ukraine requires the improvement of the current system of relations in the investment-construction-operational process, changes the traditional mechanisms of the industry and construction management through innovation. The second Concept presents the results of a comprehensive study in general of the problems of implementation of information technology, without a deep study of the state of the construction industry of Ukraine. The analysis of the main provisions of the two concepts allowed to identify the principles that should be the basis for combining three life cycle models: design, construction, operation - from the first stage of design to the reconstruction or liquidation of the object, in order to use them to innovate and improve competitiveness of objects at all stages of a life cycle and influence on work of the construction enterprises in market conditions. The educational component of the Concept as a whole does not cause objections, but requires specification of a number of decisions at the level of the Ministry of Education of Ukraine, universities, specialties and departments. In general, the combination of the two concepts provides a lot of historical and methodological material for the educational process and can be the basis for the educational process of information technology. Simultaneously, the analysis of the two concepts requires attention to differences, conclusions and generalizations that contradict the real situation in the industry and require a single system of terms.
