GREEN BUILDING CERTIFICATION SYSTEMS: COMPARISON OF TURKEY AND BULGARIA
Res. Asst. Meryem Geçimli, Prof. Ruşen Yamaçlı, Ph.D.
Sustainability is defined as it meets the needs of present without compromising the ability of future generation’s needs. Today the topic of sustainability has the urgent importance. Especially buildings consume large amount of energy and resources. Construction sector has great impact on environment. During construction process, occupancy, renovations and/or restorations and demolition, buildings consume energy, water and sources. They are also generating waste and emit harmful atmospheric emissions. Since 1990’s countries had issued a series green building assessment scheme. Leadership in Energy and Environmental Design (LEED) developed by United States of America, Building Research Establishment’s Assessment Method (BREEAM) developed by United Kingdom and German Sustainable Building Council (DGNB) developed by Germany are the most commonly used. There is now a proliferation of standards, rating and certification systems to assistance in order to deliver sustainable building in the marketplace. It is estimated that there are nearly 600 green certifications around the world. Green building rating programs vary in their approach with some outlining prerequisites and optional credits. Turkey and Bulgaria have some historical partnerships. So it can be useful to compare current situation of two countries in terms of green building certification. The comparison includes certification systems used in two countries. Bulgaria mainly depends on DGNB which is originally German evaluation system. Besides this some projects took LEED and BREEAM, as in Turkey. But the important difference in two countries is that Turkey has been developing its local system that is called Turkish Green Building Council (BEST). Thus in this paper the comparison mainly depends on BEST and DGNB. And also the certified projects in two countries are compared quantitatively. The benchmarks of two systems are compared in terms of similarities and differences. The characteristics of either standard system were summarized and some suggestions for improving Turkey’s evaluation standard for green building were proposed.
