- Abstract
Purpose: This paper aims to explain the development of an online training curriculum to enable students to acquire the transversal competences needed to work on smart cities projects. In this curriculum, a modern approach to the teaching-learning process was applied, suitable for the interdisciplinary and multinational learning challenges that smart cities impose, but within the framework of a university-industry European partnership. Design/methodology/approach: To develop the curriculum, the competences needed for smart cities, common to all disciplines and fields, had to be researched. In addition, real smart cities projects also had to be selected for work following a project-based learning methodology. For both, this study applied the Delphi method, selecting the most relevant ones based on the data obtained by performing a multi-criteria decision analysis. Findings: The procedure followed for the identification of transversal competences in a field, the design of an innovative online training program and the results of the first edition of the program are discussed. Research limitations/implications: The processes that were developed, both to detect the most relevant transversal competences and to design the online training program, could be extrapolated to other areas. Moreover, it is very likely that the competences detected in this work could also be extrapolated, for the most part, to interdisciplinary teams. Originality/value: To date, there is no European initiative addressing the challenges of smart cities that requires a major adjustment in higher education, in the relationship between universities and all the mechanisms of lifelong learning with the industry related to smart cities. This work is a pioneer in this regard.

- Abstract
Purpose: The purpose of this publication is to present a didactic concept with the targeted impact of a positive future vision. This paper reflects the effect of local educational action on the development of regionally optimised visions in rural regions of a European industrial state, compared with a rural region in the developing country of Senegal. Design/methodology/approach: An assessment and analysis of two conceptual approaches to education and technology is conducted with a view to participating in a future multicultural participatory design process, and identifying the chances that communities have to build future-oriented structures that support local roots and development. Findings: In the short-term, the technological and material results are the targeted localisation of a windmill in the (physical and cultural) countryside. In the long-term, educative and social results are expected to strengthen local civil society, which is initiated by empowering students through their self-responsibility in the Alpine region of Greifenburg, Austria. The "windmill" in the region is a publicly visible sign and a technology-based icon in the landscape, based on local consensus on several levels and inspiring further regional consensus on energy, climate protection and its active creation through entrepreneurship in civil society. Originality/value: Technology serves as a catalyst to trigger social cohesion among multiple cultures in a region and to enhance conviviality. (Contains 5 figures, 4 plates and 1 note.)

- Abstract
Purpose: The purpose of this paper is to show a practical case of dialogic web-based learning that has provided a set of questions analysing two complex technological projects in "southern" countries with effects on multicultural equity. Design/methodology/approach: Structured online review processes in multicultural and systems science curricula allow for high density of literature-based reflection and analysis. Findings: The entirety of the set of over 50 questions developed by the proposed web-based dialogic procedure represents a starting point for an in-depth assessment of the effects of deploying "northern" technology in "southern" countries. Research limitations/implications: The present case study concentrates on energy technology, notably on two hydroelectric plants presently under construction in Ilisu, Turkey, and Belo Monte, Brazil. Practical implications: The multitude of questions calls for complex technological construction projects that have to undertake sound interdisciplinary in-depth analysis of technological, environmental, economic, cultural and social consequences in order to secure a necessary level of economic, environmental and social sustainability. Social implications: Application of widely accepted planning tools such as technology assessment, environmental impact assessment and strategic environmental assessment are useful but have to be complemented by analogous tools at a cultural and social level. Originality/value: This case study operates through questioning, largely in the Socratic tradition. Questions may trigger a broad discussion process within civil societies: which is the intention of the present text. (Contains 3 figures and 1 table.)

Multimarket Multireservoir Hydro Scheduling Peak/off-peak spreads on European electricity forward and spot markets are eroding due to the ongoing nuclear phaseout in Germany and the steady growth in photovoltaic capacity. The reduced profitability of peak/off-peak arbitrage forces hydropower producers to recover part of their original profitability on the reserve markets. In their paper titled "A Planner-Trader Decomposition for Multimarket Hydro Scheduling" Schindler, Rujeerapaiboon, Kuhn, and Wiesemann propose a bi-layer stochastic programming framework that jointly optimizes the trading strategies on the spot and reserve markets. The model faithfully accounts for uncertainty in electricity prices, water inflows, and reserve activations, and it ensures that the hydropower producers can fulfill their market commitments under any circumstances. The model is numerically challenging due to the various sources of uncertainty that are revealed at different time scales and that affect the problem's objective function and constraints, and the authors propose a new planner-trader decomposition and an information restriction for its solution. A case study based on real data from Austria reveals significant benefits of simultaneously participating in the spot and the reserve markets. Peak/off-peak spreads on European electricity forward and spot markets are eroding due to the ongoing nuclear phaseout in Germany and the steady growth in photovoltaic capacity. The reduced profitability of peak/off-peak arbitrage forces hydropower producers to recover part of their original profitability on the reserve markets. We propose a bilayer stochastic programming framework for the optimal operation of a fleet of interconnected hydropower plants that sells energy on both the spot and the reserve markets. The outer layer (the planner's problem) optimizes end-of-day reservoir filling levels over one year, whereas the inner layer (the trader's problem) selects optimal hourly market bids within each day. Using an information restriction whereby the planner prescribes the end-of-day reservoir targets one day in advance, we prove that the trader's problem simplifies from an infinite-dimensional stochastic program with 25 stages to a finite two-stage stochastic program with only two scenarios. Substituting this reformulation back into the outer layer and approximating the reservoir targets by affine decision rules allows us to simplify the planner's problem from an infinite-dimensional stochastic program with 365 stages to a two-stage stochastic program that can conveniently be solved via the sample average approximation. Numerical experiments based on a cascade in the Salzburg region of Austria demonstrate the effectiveness of the suggested framework.

The last 20 years has seen rapid expansion of sustainable energy deployment in the European Union (EU) and the United States (U.S.) that is driving the demand for trained professionals. An engineering degree with coursework in sustainable energy systems is a desirable initial qualification. However, engineering students should also appreciate the societal and environmental impacts of the sustainable energy transition. Furthermore, since the sustainable energy transition is a global endeavor, an international perspective is needed. The sustainable energy engineering course described in this paper taught students the scientific and engineering principles underlying the major types of emerging sustainable energy technologies from a chemical engineering perspective. The technical content served as context for comparing renewable energy deployment in the EU country of Austria with the U.S. The broader impacts (societal and environmental) of renewable energy deployment were then illustrated through student presentations. Survey results showed that students gained understanding of the engineering fundamentals underlying these renewable energy systems and challenges of their deployment in Austria and the U.S. Therefore, a unique outcome of this course was that students gained an international perspective on the expansion of sustainable energy systems needed to secure a low-carbon energy future. • New approach for developing and teaching a sustainable energy engineering course. • Topics sequenced through Technology-Resources-Deployment-Broader Impact subtopics. • Renewable energy technologies taught from a chemical engineering perspective. • International perspectives by comparing US and Austria renewable energy deployment. • Broader (societal, environmental) impact discussions through student presentations.

In most buildings, people operate control devices such as windows, shades, luminaires, radiators and fans to bring about desirable indoor environmental conditions. These control actions have a significant impact on buildings' performance and sustainability (energy use, indoor climate). A better understanding of the logic and patterns of such control-oriented user behaviour can not only facilitate better predictions of buildings' performance, but also support the effective operation of buildings' service systems. This paper describes an extensive empirical study of control-oriented user behaviour (as related to systems for lighting and shading) in a number of office buildings in Austria. The results specifically shed light on the relationships between control actions and environmental conditions inside and outside buildings. [ABSTRACT FROM AUTHOR]

This paper presents a societal level exergy analysis approach developed to analyse transitions in the way that energy is supplied and contributes to economic growth in the UK, the US, Austria and Japan, throughout the last century. We assess changes in exergy and useful work consumption, energy efficiency and related GDP intensity measures of each economy. The novel data provided elucidate certain characteristics of divergence and commonality in the energy transitions studied. The results indicate that in each country the processes of industrialization, urbanisation and electrification are characterised by a marked increase in exergy and useful work supplies and per capita intensities. There is a common and continuous decrease in the exergy intensity of GDP. Moreover for each country studied the trend of increasing useful work intensity of GDP reversed in the early 1970s coincident with the first oil crisis. [Copyright &y& Elsevier]
