The article studies the financial compensation technology Tax Increment Financing (TIF) and offers suggestions on the prospects for attracting investment in energy conservation projects. Compensatory financing for energy conservation projects will enable them to make effective management decisions related to finding sources of funding, building their rational structure, and to share risks among project stakeholders; to protect other assets from default and increase the level of financial and credit obligations of project owners; to promote the increase of the financial leverage ratio, which will lead to an increase in the profitability of joint-stock capital and a decrease in its value as a part of total capital. The essence of TIF is to ensure that investor expenses are reimbursed through special funds, which are filled by tax revenues from the revenues of infrastructure facilities created and put into operation. The basis of this mechanism is a redevelopment, which is used to finance the investor, who invests in construction and reimburses his expenses from the special fund, where the taxes paid by the owners of new consolidated objects are accumulated. Such a scheme for financing investment projects uses the effect of increasing taxes as a result of the implementation of projects aimed at increasing the value of real estate. Based on the conducted research, the main features of the Smart City concept were singled out, as well as their characteristics, the feature of this compensatory technology, which is the locality of the financing object, was identified. Therefore, it is proposed to implement this approach within the framework of the Smart City concept, since it promotes not only the use of modern information platforms of the city's development, but also the principles of sustainable development, including the implementation of energy-saving measures.

Abstract The article presents an overview of the current situation of awareness of the Latvian citizens in the field of state-of-the-art energy-saving technologies. The authors present a wide range of data obtained as a result of a survey on the attitude of residents to new technologies and readiness to follow the development trends of a smart city. The article contains the analysis and recommendations for improving the efficiency of introducing new energy-saving and energy-efficient technologies into each household in order to create the most favourable conditions for the implementation of long-term plans for the development of smart cities in Latvia.

Green building and energy consumption are two important issues in the construction industry. Residential buildings use the biggest share of energy throughout the world. Based on investigations, most of the existing green buildings are not really energy efficient. The estimation of energy consumptions for building has become a critical approach to achieve the goals on energy consumption and to decrease emissions. There are multiple factors for energy performance of buildings, such as building characteristics, main elements and equipment, climate factors, occupants and sociological influences. This paper shows a study of energy saving enhancement methods in residential buildings by considering the three climate factors that are temperature, humidity and airflow. To achieve this goal, building simulation and classical Design of Experiment (DOE) were combined to assess the effect of these climate factors on energy saving and cooling load. Based on the ANOVA test analysis, temperature and humidity have the most significant effect on energy saving. Moreover, the optimum saving energy within the range of the model with the value of 191525 is gained at the A (temperature) and B (humidity), which are equal to 20 °C and 60%, respectively.

Summary: Different shapes of individual subjective discount functions were compared using real measures of willingness to accept future monetary outcomes in an experiment. The two-parameter hyperbolic discount function described the data better than three alternative one-parameter discount functions. However, the hyperbolic discount functions did not explain the common difference effect better than the classical discount function. Discount functions were also estimated from survey data of Dutch households who reported their willingness to postpone positive and negative amounts. Future positive amounts were discounted more than future negative amounts and smaller amounts were discounted more than larger amounts. Furthermore, younger people discounted more than older people. Finally, discount functions were used in explaining consumers' willingness to pay for an energy-saving durable good. In this case, the two-parameter discount model could not be estimated and the one-parameter models did not differ significantly in explaining the data.
