As ERKE, we managed the THY A.O. Taksim Sales Office and Experience Center with an integrated focus on sustainable interior design, energy performance and user comfort. Located in Istanbul, the project achieved LEED Gold certification under LEED v4 ID+C: Commercial Interiors with 67/110 points. Certified on June 4, 2026, the 1,975 m² project was designed as a sales office and experience center within a dense urban context. Throughout the process, we aligned LEED Commercial Interiors requirements with the project’s design and operational goals, creating an applicable, measurable and certification-ready sustainability framework across energy, water, transportation, materials and indoor environmental quality.
As ERKE, we managed interdisciplinary coordination from the earliest decision-making stages of the design process and achieved 2/2 points in Integrative Process. This approach allowed us to evaluate LEED goals together with architectural, mechanical, electrical and operational requirements within a single performance framework.
We transformed the project’s central location in Istanbul into a strong LEED advantage and achieved 17/18 points in Location and Transportation. High-quality transit access, surrounding density and reduced parking footprint strategies were correctly integrated into the certification process, strengthening the value of a LEED-certified sales office in Istanbul.
Under LEED v4 ID+C: Commercial Interiors, the project was not scored through a separate Sustainable Sites category. Site-related and location-based sustainability decisions were therefore managed under the Location and Transportation category in line with the structure of the rating system.
In Water Efficiency, we focused on reducing indoor water consumption and achieved 10/12 points. We evaluated fixtures and use scenarios in line with LEED requirements, establishing a strong water-saving performance for this LEED-certified sales office and experience center.
Energy performance became one of the highest contributing categories of the project, with 24/38 points achieved through ERKE’s engineering guidance. We structured Optimize Energy Performance, advanced energy metering and refrigerant management strategies according to the project’s dynamics, creating a measurable framework to support carbon footprint reduction.
In Materials and Resources, we managed material and waste strategies aligned with project objectives and achieved 4/13 points. We integrated a sustainable materials approach into the certification process through long-term commitment, environmental product declarations and construction and demolition waste management strategies.
Indoor Environmental Quality was addressed with a user experience-oriented perspective, resulting in 4/17 points. We managed enhanced indoor air quality strategies and interior lighting considerations to support user comfort, while optimizing other IEQ credits in line with the project scope, design priorities and operational needs.
We delivered a strong performance in Innovation with 5/6 points. Through LEED Accredited Professional contribution and innovation strategies, we strengthened the certification value of the project and added measurable sustainability benefits to this LEED Gold interior project.
In Regional Priority Credits, we achieved 1/4 point with a focus on optimized energy performance. By supporting energy efficiency in line with regional priorities, we helped make the project’s environmental impact more manageable within the Istanbul context.
THY A.O. Taksim Sales Office and Experience Center is a 1,975 m² sales office and experience center project in Istanbul. The project was evaluated under LEED v4 ID+C: Commercial Interiors and achieved LEED Gold certification with 67/110 points.
LEED certification is an international green building rating system that evaluates buildings and interiors across energy, water, materials, comfort, transportation and environmental impact criteria. LEED certification enables design and construction decisions to be managed through measurable sustainability requirements. For interior projects, the LEED ID+C system focuses on key performance areas such as user health, operational efficiency and resource consumption.
In the aviation sector, urban sales offices and experience centers are specialized spaces where brand interaction, operational efficiency and user comfort must be managed simultaneously. As ERKE, we focused on reducing energy and water consumption, supporting indoor environmental quality and converting accessibility within a dense urban fabric into sustainability performance. With this LEED-certified sales office and experience center approach, we created environmental value that strengthens both operational efficiency and visitor experience.
