Traditional industry leaders have to compete with the challenges of the new generation in emerging markets. Although the European market is competitively mature, the prosperity in global challenges makes it necessary to defend the domestic market as well as to pursue growth opportunities in emerging markets. Analyzing the trends, a comparison of the US and Chinese innovation commercialization policies from a customer perspective with Europe was distinguished. The main difference is Europe's narrowly defined customer segment, companies do not adapt to customer micro-segments with non-matching product and service requirements, because individual attraction strategies must be implemented for each branch, which increase the difficulty to draw potential global clients. The aim of this work is to analyze the US and Chinese innovation commercialization process policies from a customer perspective to gain an insight into the improvement of European national policy models. A multi-criteria decision analysis was used to compare the US and European influencing factor criteria, which focuses on customer segmentation, to determine the most influential segment. Data were also collected in the analysis of the success of European commercialization. The focus on the US end-market approach is expected to increase the value of the proximity factor by improving the implementation of European innovation policy in practice.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":"26 1","pages":"1020 - 1031"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82098479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The course ‘Energy transition and climate change’ covers one of the United Nations’ ‘Sustainable development goals’ and is one of twelve MOOCs that will enable a comprehensive education in system thinking and its applications. It shows how system thinking methods and tools can be applied to tackle current and future energy and climate problems. The goal of the MOOC is to introduce users to the internal dynamics of modern energy systems and energy transition toward CO2-neutral energy systems. The target audience of the course is students who study Environmental Engineering, Energy, Systems, or similar program and anyone else interested in insights into the topic. The course builds on previous energy supply and demand models by updating and adapting them to the existing situation. MOOC is designed by the Competency-Based Education (CBE) approach, and a literature review is used in the study to cover theoretical parts of the course. Technology Readiness Level (TRL) methodology describes the main steps of the course model development progress, and testing of MOOCs pilot version on five students is included in the final stage of the study.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":"47 1","pages":"1106 - 1117"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84983706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data were used to determine the primary share of electrical energy end-use in residential buildings. These data, the first of their kind in Jordan, were recorded by trained participants and are essential for the adoption of appropriate future energy efficiency programs in Jordan.

Traditionally cultivated in the Mediterranean area, it was abandoned in the past for other oil crops, such as sunflower. However, it is now returning to be interesting due to its adaptability to low-input cultivation practices, especially when sown in autumn. The main aim of this study is to present a Life Cycle Inventory of safflower grown in a Southern European country, i.e. Italy, based on primary data on agricultural practices used in this country. The study was carried out following ISO 14040 and ISO 14044. Data were collected from experimental fields of the University of Perugia, to ensure a specific and accurate data collection for the definition of the complete supply chain.

This paper presents the results of energy simulations conducted in TRNSYS for a single-family building depending on its location in selected European cities. For each city, air source heat pump (ASHP) was considered as an energy source for heating and cooling the building, and then an economic analysis was carried out including investment costs of air source heat pump and a comparison of operating costs of ASHP with other alternatives (i.e. gas boiler, oil boiler, or air conditioners). The results of the simulations showed that with the current energy prices the use of air source heat pumps is the most beneficial in temperate warm transitional climate (Krakow). It was also indicated that the implementation of special tariffs (reduced prices) for electricity that supplies renewable energy devices would make heat pumps unmatched as a source of heating and cooling in the residential sector.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":"81 1","pages":"648 - 657"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84337592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concept was proven with computer models that use weather forecasts, renewable energy production, and heat demand. The achieved yearly savings in grid-electricity used by the heat pump were 14.3 %.
