One of the many important challenges of the modern world is the greenhouse effect of CO2. It is necessary to implement solutions that will eliminate it. Since the easiest way to eliminate the greenhouse effect is to reduce hydrocarbons fuel consumption, it is important to evaluate the fuel (energy) consumption in long term operation. The article presents a proposal for the use of the so-called vehicle energy footprint. The method of creating such a trace is presented and illustrated with specific results of data analyzes. The data is publicly available, which means that the presented method can be independently verified. It has also been shown that the use of the method not only organizes the analyzes, but also leads to information that cannot be obtained with other methods. It therefore seems that an attractive tool has been developed for future applications.

Fossil Fuel Consumption

<p><em>Increasing economic growth will spark against increased energy consumption. But on the other hand, increasing economic growth will also trigger the occurrence of natural damage and degradation of environmental quality derived from CO2 emissions. CO2 emissions are caused by oxidation process of fossil fuel energy. This research aims to know the causality relationship between CO2 emissions, fossil fuel consumption, electricity consumption, and economic growth in Indonesia, as well as long-term relationship between CO2 emissions, fossil fuel consumption, electricity consumption, to economic growth in Indonesia in 1990 – 2019. The used data is the secondary data that is in the form of data time series. The dependent variables of this study are economic growth, while independent variables are CO2 emissions, fossil fuel consumption, electricity consumption. The method that is used in this study is Vector Error Correction Model. The results showed that there was a one-way causality between economic growth and fossil fuel consumption, and between electricity consumption and CO2 emissions. The research also shows that on long-term CO2 emissions has a negative influence, while the consumption of fossil fuels and electricity has a positive effect on Indonesia's economic growth in 1990-2019.</em></p><p><strong><em>K</em></strong><strong><em>eywords</em></strong><em>: CO2, Energy Consumption, Economic Growth.</em></p>

Occupant Satisfaction

Occupant surveys reveal how people in buildings perceive their internal environments. The Soft Landings extended handover process, which requires project teams to focus more on operational outcomes, has led to the use of occupant surveys during a three year Soft Landings aftercare period to provide a means of checking whether the desired outcomes have been met. However, little is known of the longitudinal perceptions of occupant satisfaction in buildings, and the relationships between those perceptions and the many environmental, seasonal and functional comfort variables that act upon occupant satisfaction. This paper reports the results of time-series surveys on two office buildings. Occupant satisfaction scores have been compared with the technical, organisational and functional contexts in the work environments, such as density, workgroup sizes, and cellular and open-plan layouts, to determine whether changes in these parameters have significantly altered levels of perceived occupant comfort and productivity. The research found stability in some contexts but statistical declines in others. Conclusions are made regarding the key operational factors that may contribute to changes in occupant satisfaction over time. Factors that might constitute limits to office carrying capacity are discussed. Practical application: The growing use of the Soft Landings approach to building procurement and handover, with greater emphasis on designing for improved operational outcomes, is creating a demand to understand more about occupant needs and expectations. The central government equivalent – Government Soft Landings – is similarly placing a requirement on public sector construction projects to deliver buildings with improved environmental and functional outcomes. Delivering these expectations requires construction professionals to develop skills in building performance evaluation, particularly in understanding the primary drivers that lead to high occupant perceptions of comfort, health, productivity and wellbeing. This research provides real-world evidence to clients and their design advisors on the key factors for ensuring long-term occupant satisfaction, while for building management professionals the research identifies some organisational risk factors that may lead to a fall in satisfaction during long-term operation.

Zero Emission

Abstract For the third time in the history of humankind, it is trying to implement e-mobility. There is a reasonable hope that this attempt will succeed this time. E-mobility is generally regarded as a zero emission. This sentence can only be true in a very small scope, as only in relation to selected parameters and in a very limited its dimension. The situation can change radically. If it will be take into account, the emissions in the production of electricity is necessary for the movement of this type of vehicles Second problem is the energy use amount. We know today that the energy consumption of electric cars, especially in long-term operation is too big. This general knowledge is not confirmed by research results. Both relevant databases and methods of their analysis are missing. This is an unfavourable situation because it is not possible to verify the effects of various changes introduced e.g. in the construction or technology of cars. This publication can be included in those in which it is shown how to change this situation. The analysis of the results of long-term car use can be used as a verification of various development works, especially in e-mobility, which is only just starting. In the future, it will be need to create the appropriate “big data” databases and a number of tools to analyse the data collected there.

The Internet of Things (IoT) is a constantly-evolving area of research and touches almost every aspect of life in the modern world. As technology moves forward, it is becoming increasingly important for these IoT devices for environmental sensing to become self-powered to enable long-term operation. This paper provides an outlook on the current state-of-the-art in terms of energy harvesting for these low-power devices. An analytical approach is taken, first defining types of environments in which energy-harvesters operate, before exploring both well-known and novel energy harvesting techniques and their uses in modern-day sensing.

The Impact

The paper studies the factors of secular stagnation. Key factors of long-term slowdown in economic growth include the slowdown of technological development, aging population, human capital accumulation limits, high public debt, creative destruction process violation etc. The authors analyze key theoretical aspects of long-term stagnation and study the impact of these factors on Japanies economy. The authors conclude that most of the factors have significant influence on the Japanese economy for recent decades, but they cannot explain all dynamics. For Russia, on the contrary, we do not see any grounds for considering the decline in the economy since 2013 as an episode of secular stagnation.
