A YeS-Int specification should connect the intended certification level with design decisions, implementation requirements and deliverables. This checklist helps carry the design tender’s commitments consistently into the works tender and handover file.
Establish the scope and applicable version first
- Identify building use, new or existing building status and the areas to be assessed.
- Assess the public building requirement against area, permit status and transitional provisions.
- Define the target level and criteria to be pursued.
- Identify the applicable assessment guide and annex versions in the project file.
- Assign deliverables separately to the YESU, designers, contractor and authority.
The process tables in the Ministry’s March 2026 guide can support this mapping. Use the official annexes dated 28 October 2026 when establishing current criterion requirements. Current amendment and annexes.
Design tender checklist
| Topic | Deliverable to define in the specification | Guide reference |
|---|---|---|
| Target and scope | Project brief, target criteria and responsibility schedule | Design stage; BBT 01 K1 and K3 |
| Interdisciplinary coordination | Design meetings, decision records and change tracking | BBT 02 K1 |
| Lighting | Relevant spaces, illuminance calculations and reporting of inputs and results | İOK 01 K1 |
| Energy performance | Incorporation of the minimum class B target for EKV 01 K1; the certificate or preliminary calculation appropriate to the stage | EKV 01 K1; Table 6 note |
| Water monitoring | Meter locations and project information for consumption monitoring | SAY 01 K3 |
| Waste management | Scope and delivery responsibility for the building waste management plan | SAY 02 K1 |
| Additional target studies | Methods and deliverables for energy, water, daylight, acoustic or thermal comfort studies | Table 6, according to selected criteria |
This table summarises the guide’s relationship between criteria and evidence. Not every analysis is mandatory for every project; consider use, the target and selected criteria together. Guide, printed pp. 20–26, Table 6.
Before a permit is issued, the BEP-TR Preliminary Calculation Results Form can be used under the conditions explained in the guide. Do not assign it the same delivery stage as the approved Energy Performance Certificate.
Construction tender checklist
| Topic | Requirement to make clear | Guide reference |
|---|---|---|
| Design and construction consistency | Coordinated checking of drawings, room schedules, product requirements and criterion targets | Construction Procurement, printed p. 30 |
| Commissioning | Responsible team, programme, test scope and result records | BBT 05 K1 and K2 |
| Maintenance and user information | Maintenance manuals, operating information and responsibility for delivery | BBT 06 K1 and K2 |
| If the radon criterion is pursued | Selected method, provider qualifications, report content and performance condition | YMD 03 K1 |
| Water quality target | Analysis reports and relevant maintenance records | SAY 01 K4 |
| Operational monitoring | Recording and handover arrangements for energy, water and relevant performance data | Construction Procurement, printed p. 28 |
Under the measurement pathway for YMD 03 K1, annual average radon concentration must not exceed 300 Bq/m³. Requiring a report alone does not demonstrate that the criterion has been met. Do not make this criterion a universal requirement for every project. Current annex, PDF pp. 86–87. Other handover examples are addressed in the guide, printed pp. 28–31, Table 7.
Use a consistent check for each deliverable
For each study, identify the criterion, responsible party, method, input documents, submission stage and reviewer. State which analyses must be updated following design changes and which evidence must be collected during construction. This defines an assessable deliverable rather than a report title alone.
