The Ministry of Environment, Urbanization, and Climate Change has announced significant amendments to the Planned Areas Zoning Regulation, introducing new sustainability-focused requirements. The updated regulation, published in the Official Gazette, mandates changes in areas ranging from rainwater and grey water usage to Green Certificates, electric vehicle (EV) charging units, and inclusive playgrounds. Additionally, building licences will now detail information on carcinogenic materials and green energy systems.
Mandatory Rainwater and Grey Water Systems
Starting from 1 January 2026, buildings of certain sizes and types will be required to install rainwater and grey water systems. Grey water from showers, bathtubs, and washbasins will be treated and used exclusively in toilet cisterns. The regulation applies to:
- Hotels with more than 200 beds
- Shopping centers exceeding 10,000 square metres
- Public buildings larger than 30,000 square metres
These measures are expected to save approximately 4 million cubic metres of water annually, equivalent to the water volume of Lake Mogan within 1.5 years. Additionally, all newly constructed public buildings over 10,000 square metres after 2026 will need to obtain a Green Certificate (YeS-TR).
Energy and Carbon Footprint Reduction
With the implementation of the new regulation, an estimated 600 million kilowatt-hours of energy will be saved annually—comparable to the monthly production of the Keban Dam. The regulation is also expected to reduce 50 million kilograms of greenhouse gas emissions and generate cost savings of approximately 800 million TL.
Inclusive Playgrounds for Disabled Children
To promote accessibility, at least 4% of the total park area in parks larger than 2,500 square metres will be designed for disabled children. These playgrounds will be inclusive, allowing all children to play together rather than separating disabled children into designated areas.
Enhanced Building Licences and Occupancy Permits
Building Licence and Occupancy Permit forms will now include information on:
- Green energy systems such as solar, wind, and cogeneration installations
- The presence of electric vehicle charging units
These additions aim to improve transparency for property owners and buyers while simplifying administrative inspections.
Simplified EV Charging Infrastructure
The regulatory process for installing EV charging units in residential areas will be streamlined. Electrical installations for apartment and site car parks will no longer require a separate licence, reducing bureaucratic hurdles.
Updated Wind Energy Installation Rules
Regulations on wind turbine installations have been revised to standardize procedures. Key updates include:
- Concrete base and tower surface area will now be considered part of the total construction area.
- Building licence fees will be calculated based on the square metre value of the designated area.
These measures aim to enhance systematic wind energy deployment while ensuring easier inspections.
Carbon Footprint and Digital Transformation
To improve sustainability, the carbon footprint of buildings throughout their life cycle will be measured and capped. Additionally, all building data will be digitized, enabling the creation and management of 3D building models. This transition to digital platforms will expedite licensing and approval processes.
