“…In Turkey, the share of renewable energy in the total electricity production is approximately 20% and is represented mainly by hydropower (16.1%), wind (3.3%), and other sources (biomass, solar, and geothermal) (1.4%) [50]. In Spain, the share of renewable energy in the total electricity production is approximately 35% and is represented mainly by variable renewable energy sources, such as wind (19%), solar (5%), and other sources (biomass, cogeneration, and the remaining) (11%) [51]. In Italy, wind and solar are also the most popular renewable energy sources, with 8% of the country's electricity production provided by photovoltaic (PV) panels [52].…”

Leadership in Energy and Environmental Design (LEED) has five basic categories: Sustainable sites (SS), Water Efficiency (WE), Energy and Atmosphere (EA), Materials and Resources (MR), and Indoor Environmental Quality (EQ). Additionally, in LEED 2009, the U.S. Green Building Council (USGBC) introduced regional priority (RP) points to adapt LEED to the local conditions of foreign countries. However, the appropriateness of the RP points stated for the Mediterranean basin has not yet been evaluated. Thus, we studied the similarities and differences in performances of LEED 2009 Commercial Interiors (CI) and LEED 2009 Core and Shell Development (C&S) Gold certified projects in Turkey, Spain, and Italy. We revealed that the categories without RP points, SS, MR, and EQ, performed similarly in all three countries, thereby signaling the correctness of CI and C&S applications in the Mediterranean basin. However, the categories with RP points, WE and EA, performed differently. It can be suggested that the following RP points would be beneficial for all three countries: (i) in the MR category, RP points that initiate decreases in virgin construction material; (ii) in the WE category, RP points that encourage water saving; and (iii) in the EA category, RP points that encourage using renewable energies.

“…However, in version 4 of the certification (EAc2, Existing Building Commissioning-Implementation), Spain improved its achievement (PAS = 75), approaching Finland's PAS (100). Only the ongoing commissioning issue (EAc2.3 in version 3 and EAc3 in version 4 of the certification) had mostly low PASs in both countries (0-25), with the exception of Finland's PAS in version 4 of the certification (50).…”

“…This was surprising, as the share of renewable energy constitutes approximately one third of all produced energy in both countries. In Finland, renewable energy is produced by hydropower (28%) and wind, solar, and biofuel (3%) processes [49], whereas in Spain, it is produced by wind (19%), solar (5%), and biomass (11%) processes [50].…”

This study aims to assess the similarities and differences between Finland and Spain in terms of Leadership in Energy and Environmental Design for Existing Buildings (LEED-EB) Gold large office building-type projects transitioning from version 3 (v3) to version 4 (v4). The percentages of the average scores are used here to assess the achievements of the LEED-EB data. The natural logarithm of the odds ratio lnθ and Fisher′s exact 2 × 2 tests with a mid p-value are used to evaluate dichotomous data, while the exact Wilcoxon–Mann–Whitney and Cliff′s δ effect size tests are used to evaluate ordinary data. The results for LEED-EB Gold large offices demonstrate similar certification strategies in Finland and Spain. These results may be useful to LEED-EB practitioners in Finland and Spain for facilitating the selection of appropriate certification strategies in line with identified high-performance credits for large offices.

“…The current situation of the conventional power sources in Spain has been discussed by the authors elsewhere [13]. Therefore, in this section, we will focus on the renewable energy sector, which is the one that will undergo major changes in relation to the 2030 electricity transition.…”

Recently, the European Union has recognized that more ambitious plans in reducing emissions are needed in order to comply with the target 1.5–2° warming limit for this century. Along this line, the main objective of this paper is to study the evolution of the power sector in Spain, taking into account the Paris Agreement and the further European Union Directives. In particular, we have studied the substitution by renewable energies of all coal power plants before 2030. For this study, we have applied linear programming techniques to optimize the deployment of the additional wind and solar resources. If, in addition to the substitution of coal power plants, we also consider the expected increase in demand for the period 2019–2030, we find that the present park of renewables should be increased by a factor of about 115%. We have also statistically analyzed the amount of surpluses and shortages in energy, assuming that the demand curve would have a daily shape similar to the present one. As a result, we have found that additional storage capabilities of around 55 GWh for 11 h would be needed in order not to waste more than 25% surplus energy by curtailment. As for backup, we propose in a first step to use the overwhelming amount of gas combined cycle units which are available.
