Turning a Green Certificate objective into project and documentation responsibilities
Energy, water, material and indoor environmental decisions for a public building are developed by different teams. A YeS-Int objective requires those decisions to be assessed against the relevant criteria and their implementation documented. AECO's consultancy connects the client's objectives with technical studies and clarifies who will prepare each item of information and how it will be tracked.
The service supports public projects within the mandatory scope and voluntary YeS-Int applications. We begin by examining building use, ownership, area and permit status. This connects the application scope with the information and documents the team needs to prepare. Responsibilities during design, procurement and construction are incorporated into the work plan.
Mandatory scope and voluntary applications
The provision relating to Article 57/A of the Planned Areas Zoning Regulation took effect on 1 January 2026. It requires YeS-Int Green Certification for publicly owned healthcare, education, dormitory and service buildings requiring a new building permit where total building construction area is 10,000 m² or more. Transitional provisions and the project's permit and tender status are also considered together in the scope assessment.
Projects outside the mandatory scope can apply voluntarily. The Ministry of Environment, Urbanisation and Climate Change announcement of the Green Certificate Implementation Guide for Public Buildings explains how criteria relate to design and construction; the source is in Turkish. Detailed assessment follows the relevant legislation and applicable guides.

The role of a Green Certification Specialist
A Green Certification Specialist advises the owner and project team on assessment criteria and coordinates technical studies and application documents. At AECO, this process is led directly by our founder Taygun Yüksel, who holds the Yeşil Sertifika Uzmanı credential. Reviewing the application is the responsibility of the authorised assessment body.
We define priorities and documentation responsibilities at the outset. Technical needs concerning energy, water, daylight, materials and indoor conditions are connected with assessment criteria. The analyses needed and the extent to which available information can be used are clarified through project conditions.
Tracking work from design to the submission package
The work plan identifies information and documents to be prepared by each team. As design decisions develop, we review their relationship with the criteria and track open matters with the responsible teams. We assess how product or construction changes affect the documentation. Application preparation therefore progresses alongside the records produced during the project.
Deliverables include the initial scope assessment, responsibility and document tracking records, coordination of agreed technical studies and follow-up of review questions. The proposal explains the analyses and deliverables for the project. We route the assessment body's questions to the relevant teams and coordinate responses and supporting documents.
Resources for preparation
For the relationship and differing priorities of YeS-Int and LEED, see our comparison article. AECO's yes-tr.com and yesilsertifika.net sites also provide regulations, guides and process information in Turkish. During an initial discussion, available project documents help establish the priority steps.
