The economic impact of sports mega-events : The case study of the FIS Nordic World Ski Championship Falun 2015

Since the second half of 1990s, the economic impact of sports mega-events concerned the researchers, the public and the professionals. The investment of public funds and the effects on several sectors of the economy motivate the economic impact studies. The economic impact of the FIS Nordic World Ski Championship Falun 2015 to the region of Dalarna is the topic of this thesis. This requires the calculation of direct, indirect and induced economic impact. Within the analysis, data from a questionnaire survey conducted on seven different days during the event are used. The final sample of the analysis contains 893 observations. The segmentation approach was applied for the calculations and the visitors were classified regarding their choice of accommodation. The regional economic impact is calculated at 321 M SEK and the employment effect on the tourism sector is estimated. However, the lack of information limits the study. The analysis could be extended with an accurate investigation of certain issues. Further, the impact of the event should be estimated from all the perspectives. The organization of sports mega-events creates tangible and intangible effects to the host-city. The thesis reviews literature on the economic impact studies of sports mega-events. The results of the study can be used for a comprehensive analysis of the case study. Further, the professionals of the tourism and the event could be benefited.

Energy efficient and economic renovation of residential buildings with low-temperature heating and air heat recovery

With the building sector accounting for around 40% of the total energy consumption in the EU, energy efficiency in buildings is and continues to be an important issue. Great progress has been made in reducing the energy consumption in new buildings, but the large stock of existing buildings with poor energy performance is probably an even more crucial area of focus. This thesis deals with energy efficiency measures that can be suitable for renovation of existing houses, particularly low-temperature heating systems and ventilation systems with heat recovery. The energy performance, environmental impact and costs are evaluated for a range of system combinations, for small and large houses with various heating demands and for different climates in Europe. The results were derived through simulation with energy calculation tools. Low-temperature heating and air heat recovery were both found to be promising with regard to increasing energy efficiency in European houses. These solutions proved particularly effective in Northern Europe as low-temperature heating and air heat recovery have a greater impact in cold climates and on houses with high heating demands. The performance of heat pumps, both with outdoor air and exhaust air, was seen to improve with low-temperature heating. The choice between an exhaust air heat pump and a ventilation system with heat recovery is likely to depend on case specific conditions, but both choices are more cost-effective and have a lower environmental impact than systems without heat recovery. The advantage of the heat pump is that it can be used all year round, given that it produces DHW. Economic and environmental aspects of energy efficiency measures do not always harmonize. On the one hand, lower costs can sometimes mean larger environmental impact; on the other hand there can be divergence between different environmental aspects. This makes it difficult to define financial subsidies to promote energy efficiency measures.

Decisions with Impact on Energy Reduction Opportunities : Swedish manufacturers and buyers of new single-family houses

This article discusses some of the complexities of human decision-making. It aims, in particular, at relating the nature of decision-making to the illusory dichotomies of change and stability, individual actions and cultural sharing. Serving as an illustration to the discussion of the article is ongoing fieldwork in contexts of buying, selling and constructing pre-fabricated detached houses in the central Sweden, and the very specific question of how decisions to install one kind of heating-system rather than another come about. A common reductionism is to narrow down the understanding of decisions about heating systems and energy consumption to conscious choices made by individual householders. I have asked myself whether, on the contrary, anyone actually makes such decisions at all. Perhaps some of these decisions are merely outcomes of interaction between different individuals with their respective responsibilities and focuses of interest.

Economic Evaluation of a Solar Charged Thermal Energy Store for Space Heating

A thermal energy store corrects the misalignment of heating demand in the winter relative to solar thermal energy gathered in the summer. This thesis reviews the viability of a solar charged hot water tank thermal energy store for a school at latitude 56.25N, longitude -120.85W
