Every modern building tells a story long before people walk through its doors. Architects sketch the design, engineers calculate structural strength, and construction teams bring ideas to life. Yet another group quietly influences how that building will perform for decades. Sustainability consultants work behind the scenes to reduce energy use, improve indoor environments, lower carbon emissions, and help buildings meet internationally recognised environmental standards.
As governments tighten climate regulations and businesses set ambitious sustainability goals, green building consultancies have become an important part of the construction industry. These firms help developers create buildings that are attractive and efficient, healthier for occupants, and environmentally responsible.
One company contributing to this transformation is ERKE Sustainability Consultancy, a Türkiye-based consultancy that has spent more than 19 years helping developers, manufacturers, and project teams improve environmental performance through technical expertise and internationally recognised sustainability standards.
ERKE Sustainability Consultancy Builds Sustainable Solutions Across the Construction Industry
ERKE Sustainability Consultancy was established in 2007 in Istanbul, Türkiye. The company initially operated as an engineering consultancy before expanding its services in 2009 to include Green Building, Product Sustainability, and Corporate Sustainability Consultancies. This expansion reflected the growing demand for sustainable construction and environmental performance across the building industry.
Today, ERKE operates from offices in Istanbul, Dubai, and London, supporting projects in different countries through sustainability consultancy and engineering services.
According to the company’s official website, ERKE has completed more than 500 projects covering over 40 million square metres. Its portfolio includes office buildings, commercial developments, hotels, healthcare facilities, industrial buildings, educational institutions, mixed-use projects, and data centres.
The company works closely with developers, architects, engineers, contractors, manufacturers, and building owners to improve environmental performance throughout a building’s life cycle.
ERKE Supports International Green Building Standards
Sustainable buildings require careful planning, technical analysis, and recognised environmental standards. Developers increasingly seek certification systems that demonstrate measurable improvements in energy efficiency, water conservation, indoor environmental quality, and responsible material selection. ERKE provides consultancy for internationally recognised certification systems, including LEED, BREEAM, WELL Building Standard, EDGE, Fitwel, Passive House, Zero Energy Buildings, and other sustainability programmes listed on its official website.
The company prepares technical analyses and project documentation that support certification requirements. Its services include energy modelling, daylight analysis, commissioning, electrical engineering, lighting design, carbon consultancy, ESG consultancy, circular economy consultancy, and Net Zero consultancy. By combining engineering knowledge with sustainability expertise, ERKE helps project teams evaluate environmental performance before construction begins and throughout the development process.
Product Sustainability Strengthens Responsible Construction
Sustainable construction depends on efficient buildings but and on environmentally responsible building materials. ERKE assists manufacturers by preparing Environmental Product Declarations (EPDs) and Life Cycle Assessment (LCA) studies. Environmental Product Declarations provide independently verified information about the environmental impact of construction products throughout their life cycle. These documents help architects, developers, and contractors compare products using transparent environmental data.
Life Cycle Assessment studies evaluate environmental impacts from raw material extraction through manufacturing, transportation, product use, and end-of-life disposal. The information helps manufacturers improve environmental performance while supporting sustainable procurement decisions. By providing these services, ERKE contributes to greater transparency across the construction supply chain.
More Than Nineteen Years of Experience Reflect Consistent Growth
Over the years, ERKE has steadily expanded both its expertise and project portfolio.
ERKE has completed more than 200 green building certifications, over 120 electrical design projects, and more than 200 sustainable material certification processes. The company also shared its 2025 Annual Highlights, reporting the successful completion of 59 LEED certification projects across Building Design and Construction (BD+C), Interior Design and Construction (ID+C), and Operations and Maintenance (O+M) rating systems.
ERKE further reported that more than 90 per cent of its completed projects during 2025 achieved LEED Gold or higher certification levels. The company also completed 11 Environmental Product Declarations and 7 Life Cycle Assessment reports covering 19 products during the same year. These figures, published by ERKE, reflect the company’s continued focus on measurable sustainability outcomes.
Publicly Reported Projects Demonstrate Technical Capability
ERKE has publicly highlighted several projects that showcase its sustainability consultancy services.
The Citibank Office at Allianz Tower achieved LEED Platinum certification under the Interior Design and Construction rating system with ERKE providing sustainability consultancy. The KKB (Kredi Kayıt Bürosu) Data Centre also achieved LEED Platinum certification. Data centres require continuous operation and significant energy consumption, making environmental performance particularly important.
Another publicly announced project is the Star of Bosphorus Data Centre, which achieved LEED Gold certification with ERKE serving as the sustainability consultant. These projects demonstrate the company’s experience in supporting technically complex developments while helping clients meet internationally recognised environmental standards.
ERKE Green Academy Reflects Its Sustainability Philosophy
ERKE has also applied sustainable design principles within its own workplace.
The company’s headquarters, ERKE Green Academy, achieved LEED Platinum certification and serves as both its corporate office and a training centre dedicated to sustainability education. The building demonstrates how environmental design, energy efficiency, and healthy indoor spaces can be integrated into a working environment while supporting professional learning and knowledge sharing.
