There is a need to increase energy efficiency and use resources sustainably by means of energy-efficient building systems. In the study, vertical greening systems were integrated with a Double skin façade system and were applied as a Double skin green façade. Different improvement scenarios were produced for the cities of Karabük and Antalya, which have two different climates. Then, the scenarios were simulated with DesignBuilder program, and energy consumption values were determined accordingly. As a result, the energy efficiency of the DSF scenario applied to the south and west façades for Karabük and the scenarios with 30% greenery coverage on the façade were determined to be better. DSF applied on the south side of building was considered to be more appropriate for Antalya. [ABSTRACT FROM AUTHOR]

Currently, there is no official green or sustainable built environment evaluation system in Turkey. When a certification is required for a building or a site, various certification systems are employed. To meet the demand, the Turkish Green Building Council released an evaluation system called B.E.S.T. in 2013. In this paper, the B.E.S.T. evaluation system is introduced as well as a sample application. The evaluation of the Yalova University Engineering Faculty Building using the B.E.S.T. evaluation system is presented. Field research was conducted and evidentiary documents were gathered in preparation. The study employed both analytical and field research methodologies in this regard. As a result of the study, Yalova University Engineering Faculty Building was assessed to be eligible for the lowest level certificate, the 'Approved' degree of the B.E.S.T. evaluation system. Furthermore, the results achieved with the B.E.S.T. were compared to those acquired previously with other green or sustainable building evaluation systems. HIGHLIGHTS - An exemplary set of the evaluation was performed for university campus buildings with the B.E.S.T. certification system. - The conducted case study is one of the earliest samples of B.E.S.T. evaluations. - A comparison of B.E.S.T. with LEED and BREAM is provided. - The importance of establishing a local certification system has been discussed.

Enhancing energy efficiency is important for sustainable economic development and environmental-related issues such as carbon emissions. Therefore, measuring energy efficiency is crucial for countries to achieve economic and environmental objectives. In this study, we utilize the TOPSIS method with the intent of monitoring the energy efficiency of Turkey from the 1980 to 2018 period. Several variables such as renewable and nonrenewable energy consumption, GDP, labor force, and capital stock are employed in calculating energy efficiency scores. Thereafter, we analyze the long-term, symmetric and asymmetric effects of some contextual variables such as capital stock-labor force ratio, renewable energy consumption-total energy consumption ratio, and carbon emission-total energy consumption ratio on energy efficiency via ARDL and nonlinear ARDL models. Results from the linear model indicate that an increase in the renewable energy consumption-total energy consumption ratio and capital stock-labor force ratio increase the energy efficiency. In contrast, an increase in the carbon emission-total energy consumption ratio decreases it. The nonlinear ARDL model, on the other hand, signals asymmetric effects in the long-run but not in the short-run. [ABSTRACT FROM AUTHOR]
