The Impact

The Life Cycle Cost (LCC) analysis on selected alternative systems was carried out to reduce the demand for potable water and energy in a detached house designed in accordance with the concept of environmentally friendly house. The tests included a rainwater harvesting system, graywater recycling system, solar panels, photovoltaic panels, air heat pumps, ground heat pumps, wind turbines, drain water heat recovery units, and biomass boilers. The analysis was made for many investment variants where different combinations of the mentioned solutions were applied. In addition to the LCC analysis, some tests were also carried out to determine an impact of the investment options on the environment. This was done by calculating CO2, SO2, NOx, CO and dust emissions. The research was carried out for a different number of occupants and variable levels of water consumption, which allowed determining the impact of these parameters on the results obtained. They showed that for any of the computational cases the traditional option of the installation was not the most advantageous solution in financial and environmental terms, and the systems in question could be an alternative to this option. Thanks to their implementation, the consumption of fossil energy resources and natural water resources will be reduced, and the emission of pollutants will be limited, which will contribute to an improvement of the natural environment.

The Impact

This paper explores the impact of water conservation and rainwater harvesting practices implemented at the site or district scale on the infrastructure, energy and water cycles of their larger urban systems. A case study is presented of a conceptual development in a Southeast Asian climate. Two technologies are examined: water-efficient fixtures and appliances and rainwater harvesting and beneficial use. Practices to reduce water consumption at the site or district scale have implications in the larger system, ranging from reductions in water that has to be treated and distributed, reductions in wastewater that has to be collected and treated, and reductions in energy consumed. Similarly, using rainwater for irrigation will reduce the amount of potable water demand, and will have system energy implications. The paper considers performance criteria for the entire water-energy system, including peak runoff, pollutant loads, energy and carbon footprints.

This paper describes a group activity concerning the topic of climate change, designed to introduce the concepts of sustainable development into a Robotic Engineering degree. The purpose of this activity was to make students reflect about the impact of their work on the planet as future engineers by asking them to design an environmentally friendly robot that also integrated social and economic aspects, covering the three dimensions of sustainability in this way. Students were surveyed in order to study different aspects of their commitment, attitudes, practices, and motivation towards sustainability. In addition to the overall analysis of the survey, three specific studies were carried out with the aim of comparing the responses of different population groups: (i) Students who completed the proposed assignment and students who did not, (ii) female and male students, and (iii) roles played in the assignment. The results of the analysis revealed the high commitment of the students with respect to sustainability, but also a lack of active participation and awareness of their impact as future engineers. The activity was not only a way to introduce sustainability concepts, but in many cases, it also became a motivation for the participants, especially for the female students.

The Impact

The basis for sustainable and environmentally friendly development is gradually becoming aware of the importance of working more ethically and transparently and in a more humanistic way, as well as addressing the needs of people and society. In this case, the key challenge for higher education institutions (HEIs) is to train the conscious and responsible citizens who can take care of the country’s future. This article focuses on comparing the ability of HEIs in Poland and Ukraine to promote sustainable development (SD) by implementing the concept of social responsibility (SR). The research is based on the methods of statistical analysis, sociological survey, case study, abstract-logical, tabular and graphical method. The paper argues that HEIs have a wide range of tools to promote SD. These tools should be divided into three groups, namely: 1) including SD issues in educational programs; 2) developing knowledge and solutions for SD; 3) creation and participation in SR initiatives. The proposed mechanism of the impact of HEIs on SD through the implementation of the concept of SR will allow HEIs to take an active part in the life of the region and the country, namely: identify the needs, engage the stakeholders, facilitate the interaction, disseminate the effective practices, and develop SD strategies. The practical value of the obtained results is that the implementation of SR initiative by HEIs will promote the environmentally friendly development of the country and regions. As a result, it will increase the impact of HEIs on economic, technology and cultural development, human capital formation, solving social problems, building civil society, improving the environmental status.

The Impact

Based on socio-economic development and population growth, rapid urbanisation is currently happening in China, leading to urban expansion and land use changes. This, in turn, affects biodiversity, habitats and ecosystem services. It is therefore important to identify and assess the impact of urban development policies (UDP) on ecosystems and their components at a policy level. Ji'nan City, the capital of Shandong Province in Northern China, has been taken as a case study for assessing the ecological impact of UDP. The study found that, influenced by the traditional economy-oriented development strategy, the former UDP of Ji'nan City was mainly focused on urban socio-economic growth by speeding up the construction of urban infrastructure facilities, expanding urban built-up areas as well as strengthening the development of resource- and pollution-intensive industry, which in turn has negatively influenced the ecosystem services. The promulgation of eco-environmentally friendly UDP would contribute to protect and maintain the ecosystems and their components. Finally, recommendations for informing the legislation of new environmentally friendly UDPs and furthering the implementation of ecological impact assessment (EcIA) in China are proposed.

The Impact

One of the strategies of the European Green Deal is the increment of renewable integration in the civil sector and the mitigation of the impact of climate change. With a statistical and critical approach, the paper analyzes these aspects by means of a case study simulated in a cooling dominated climate. It consists of a single-family house representative of the 1980s Italian building stock. Starting from data monitored between 2015 and 2020, a weather file was built with different methodologies. The first objective was the evaluation of how the method for selecting the solar radiation influences the prevision of photovoltaic productivity. Then, a sensitivity analysis was developed, by means of modified weather files according to representative pathways defined by the Intergovernmental Panel on Climate Change Fifth Assessment Report. The results indicate that the climate changes will bring an increment of photovoltaic productivity while the heating energy need will be reduced until 45% (e.g., in March) and the cooling energy need will be more than double compared with the current conditions. The traditional efficiency measures are not resilient because the increase of the cooling demand could be not balanced. The maximization of installed photovoltaic power is a solution for increasing the resilience. Indeed, going from 3.3 kWp to 6.9 kWp for the worst emission scenario, in a typical summer month (e.g., August), the self-consumption increases until 33% meanwhile the imported electricity passes from 28% to 17%.

Our paper deals with a micro-study of one residential building in the city center of Brno (Czech Republic) where we strived to identify and better understand the main factors behind the successful implementation of environmentally friendly solutions during the regeneration process. We followed the unique, complicated, and often conflictual story of the regeneration (conducted during the years 2010–2020) of the residential building, which was originally built in the 1930s. In total, 18 solutions were discussed—all four solutions on the state level of centralization were realized, only two of six solutions on the building level of centralization were materialized, and six of eight decentralized solutions were realized during the regeneration process. In the field of energy savings requiring high investments, a significant dominance of centralized solutions (on the state level) was identified. Centralized solutions on the building level such as heat pumps or solar panels were not realized. In the area of waste management and care for community greenery (that did not require large investments), we see as the most beneficial the promotion of decentralized solutions in the form of community-funded communal composting or the planting of new greenery. The formation of various regeneration options, which is discussed in detail, appeared as an integral instrument for dealing with conflicts among residents during the planning phase.
