[CEST2019_00604] Design-based and model-based estimations of distribution and abundance of dolphin populations in Gulf of Corinth, Hellas
by Karamitros G., Gkafas G.A., Giantsis I.A., Martsikalis P., Kavouras M. and Exadactylos A.

In recent years a major scientific effort has been focused on the protection of marine mammals. Gulf of Corinth is part of the Natura 2000 network (GR2530007) since 2016, with Special Areas of Conservation and constitutes an important habitat for striped dolphin (Stenella coeruleoalba), bottlenose dolphin (Tursiops truncatus) and short-beaked common dolphin (Delphinus delphis).

[CEST2019_00485] Indoor and outdoor environment impact over the generic conditions for thermal bridge appearance
by Ivanov M., Mijorski S.

The presented study considers the numerical modelling of a thermal bridge distribution, based on conjugated heat transfer and Computational Fluid Dynamics (CFD) model of approximated external concrete wall. The thermal bridge distribution is cross-analyzed relative to the indoor and outdoor air parameters, under the corresponding structure’s thermal properties. The main analyzed parameters in the study are the surface temperature on the exterior wall, outdoor air temperature and wall thermal conductivity.

[CEST2019_00238] Employing data-driven models in the optimization of chemical usage in water treatment plants
by Kandris K., Romas E., Tzimas A., Gavalakis E.

One of the most challenging tasks in potable water production is the cost-efficient and consistent operation of water treatment plants (WTPs) that treat raw water of variable quality and quantity. To increase process stability and optimize the usage of resources, two data-driven models simulated coagulation in two WTPs. The data-driven models were successfully trained on monitoring data collected from the two WTPs (mean errors of effluent turbidity were below 0.5 NTU in both case studies) and were subsequently employed in the optimization of two historical periods of the WTPs.

[CEST2019_00239] A computationally efficient metamodeling-based approach for the automatic calibration of coupled hydrodynamic and water quality models
by Kandris K., Romas E., Tzimas A., Pechlivanidis I., Giardino C., Bresciani M., Schenk K., Bernert H.

Computational budget is a severe limitation on the automatic calibration of expensive hydrodynamic and water quality models. To tackle this limitation, the present work formulated a metamodeling-based approach for parameter estimation of such models and assessed the computational gains of this approach compared to a benchmark alternative (a derivative-free optimization method).

[CEST2019_00213] Testing and validation of ENVI-met simulation based on in-situ micrometeorological measurements: the case of Syntagma Square, Athens, Greece
by Koletsis I., Tseliou A., Lykoudis S., Pantavou K., Tsiros I.X.

The present paper focuses on the development of a methodology that simulates micrometeorological thermal conditions in an urban context based on weather station data. The micrometeorological conditions at Syntagma square, the central square of Athens, Greece were simulated by ENVI-met software in order to evaluate the thermal conditions experienced by its users. Located in the heart of city’s commercial activity, the square attracts many visitors, especially during summer months, when extreme thermal conditions could be encountered.

[CEST2019_00091] Do Environment-related technologies strengthen the competitiveness of local systems?
by De Noni I., Ganzaroli A., Orsi L.

Environmental innovation is considered one of the key drivers of sustainable development and economic growth. However, we still know very little about the organizational factors underling the development of this category of innovations and their relative competitive effect. In this paper, we focus on regions and we look at the specific effect of environment-related technologies and collaborative environmental inventions on the competitiveness of European regions.

[CEST2019_00092] A Comparison between the Past and Future Expected Wind Conditions in the European Coastal Environment of the Mediterranean Sea
by Rusu E.

In the last years, exploitation of the wind power has been constantly increasing together with the size of the turbines. Furthermore, by 2030 wind energy is expected to supply around 30% of EU’s power demand. Offshore wind represents a significant future opportunity, since resources are abundant and more stable. In the North and Baltic seas more experience is gained on bottom fixed turbines, but also many initiatives emerge to accelerate the development of floating devices, such as the projects in the Mediterranean and Atlantic.

[CEST2019_00104] Green jobs as an unemployment solution
by Sulich A., Rutkowska M.

Currently, the priority in the EU countries is the subject of unemployment, due to the economic and social situation in many countries and young people unemployment. Although unemployment in some other counties has dropped, it is still quite high. The new economic models based on heterodox economics point to some new and innovative solutions in this area, among others - creating new green jobs. Green employment is the beginning of new solutions that accept the principles of sustainable development, and the green economy, which creates new companies.
