The paper Analysis of Freight Distribution Flows in an Urban Functional Area inter-relates urbanization context of the different morphology of the cities, supply requirements in the cities (logistics flows) and humans quality of life in the cities. The problem is stated from three different approaches with the aim of improving the spatial and transport planning policy measures, as well as the measures of social and economic policy in the cities. Empirical results are based on the case of the Mediterranean city in Spain. The author’s provide valuable data set of freight distribution flows to study urban logistics in Mediterranean compact city and implications of the measures in the society context - quality of life in the cities, economic context – distribution, congestion environmental and energy issues and urban context – the importance of the morphological characteristics of the category of small historic area – medium-sized cities, with “sensitive” areas owing to the importance of the cultural or historical terms.

Due to the increasing number of requests for homecare services, institutions struggle to perform in urban traffic, which eventually makes travel times longer and less predictable and, therefore, leads to a declining service quality. Homecare delivery scheduling and planning tools must lead to efficient reliable routes that allow the nursing crew to make the least efforts and use the fewest institutional resources, and that consider urban sustainability goals. For the case study, a European city was selected with 58,000 people of whom 73 patients received long-term care at homes provided by 11 homecare nurses. While maximising patient satisfaction, a homecare-planning algorithm considered many means of transport and minimised travel times. The study reduced the total nurses’ working hours/day by a bus and walking combination, and by comparing if nurses ride e-bikes, which respectively reduced 35–44% of the total time that nurses spent travelling. This result is applicable to an urban environment where the public transport network is sufficient and biking is allowed on a reasonable number of roads. Better homecare management can support the efficient use of resources of health care institutions, high-quality home care and sustainable development.

The issue of Municipal Solid Waste (MSW) management is an ever-increasing problem, especially because solid waste from industry and other Closed-loop Supply Chain Waste (CLSCW) is included in MSW. Dealing with very large amounts of MSW per capita is a global problem, forcing municipalities and industry to develop new systemic approaches and technological solutions. One the well accepted solutions is energy recovery from MSW and (CLSCW). The Waste-to-Energy (WTE) policy significantly reduces the volume of waste disposed in landfills, influences the reduction of total green house as emissions, and gives 'the potential for generating electricity or developing co-generation of electricity and heat. Never the less, there are still high uncertainties regarding the optimal decision on investments in cogeneration plants. In this paper we shall not discuss the technical characteristics of plants. Our focus is on the choices regarding investment costs and efficiency, which also depend on the uncertain demand for supply system products, which is in correlation with the quantity of waste. In general, their covered items must be distributed from the recycling facility back to production, and waste items must be sent to landfills, for which taxes and fees have to be paid. Alternatively, waste items can be reversibly use data source energy with several technological methods - most commonly the burning process. The uncertain energy efficiency of cogeneration plants and the uncertainty of demand appear simultaneously. In this paper, the methods for supporting decisions in optimal investment in the urban cogeneration plant in case of joint actions of local authorities responsible for MSW and (CLSCW) managers is considered when energy efficiency is normally distributed or fuzzy, at volatile demand, which has never been studied jointly. Extended MRP theoretical result are compared to the solutions of fuzzy reasoning.

We are researching a public-private partnership in the construction of infrastructure, from aspect of a private partner who is the owner of the land on which the infrastructure would have been built. We analyse and evaluate the land as an input in to the project. We are analyse different possible evaluations of the value of the land at the moment of the partner's entry into the project, and also through the duration of the entire project. The price of the land can change significantly during the duration of the project, whether due to global changes in the market, either due to spatial planning changes (urban planning) or from micro-location market changes (better accessibility, infrastructure). When setting up the model, we are primarily interested in the value of the land as a real contribution to the project. The developed model of valuation harmonises the value of in-kind contributions in the public-private partnership for cases of construction of infrastructure, which is placed in space. The characteristic of the model is that it operates dynamically and takes into account changes in the real estate market through the entire economic duration of the project. We believe that the model could encourage partners to participate in such projects, but above all we believe that the model will be stimulating in terms of quicker discussions and, consequently, the development of projects.

Building energy performance forecasting is a well-known challenge. Several studies show that, when in operation, heating, ventilation and air conditioning (HVAC) systems in buildings do not perform exactly as predicted because of climate differences, user and operational profiles deviations, and furthermore due to technical changes and imperfections that occur in construction process. In engineering practice it is common to use monthly method (EN ISO 13790) for calculation of residential building energy performance. However, if this method is used in a commercial tool or in a national methodology for energy performance certification (Directive 2010/31/EU), it is usually customized with a number of default values, simplifications, and predefined weather data to facilitate the work or architects and engineers. Mismatching of calculated energy performance (either at design stage or for a building as built) and metered energy use of a building is becoming a problem in the real estate market. More accurate modelling based on hourly dynamic simulation method is a promising solution to diminish the discrepancies of calculated and metered energy use. The paper investigates the calculated and metered energy use of monitored apartments in a highly energy efficient apartment building Eco Silver House.
