A green certification target for a public building requires coordinated preparation across design, construction and operations. The authority needs to understand who supplies information and when it will be used. Planning YeS-Int early helps connect objectives with project documents and enables different teams to work within a common scope.
What should be clarified first?
The building's position within YeS-Int should be reviewed first. Ownership, use, area and new building permit information are considered together. Applicability of mandatory requirements should be checked against the actual project information. The Ministry's implementation guide is a primary preparation resource. Ministry — Public building implementation guide.
Bringing together available plans, project stage and existing decisions is useful at the outset. It allows later studies to be connected to the developing design. Our guide to mandatory YeS-Int for public buildings explains applicability in greater detail. General preparation and the regulatory scope review can form part of the same initial assessment.
Turn objectives into project decisions
Energy, water, materials and indoor conditions need contributions from different teams. Each objective should be connected to a design decision and the information that supports it. A façade choice, for example, affects analysis inputs as well as architectural appearance. Establishing this link early helps avoid treating preparation solely as evidence collection at the end.
Teams need to know both the decision and its current status. An unconfirmed product or system should not be presented as a completed installation. As work progresses, the response to each objective can be reviewed. The authority can then distinguish resolved matters from those still awaiting a decision.
Position the YESU role correctly
The Green Certificate Expert, known as YESU, helps prepare the application against the criteria and submits it through the system to the assessment organization. The Ministry's guide recommends early expert involvement across project stages. Technical preparation and application assessment have different responsibilities.

The role does not replace architects and engineers. The responsibilities of the technical team preparing information, the coordinating party and the assessment organization should be clear. The authority's decisions also belong in this arrangement. Clear roles reduce repeated requests for the same information in different formats.
Maintain continuity through procurement and construction
A solution targeted during design should have a corresponding installed outcome. Technical specifications should therefore connect to the evidence expected from the contractor. Understanding why a product was selected and which properties matter helps the team assess alternatives later. Our YeS-Int specification guide provides further detail.
Changes during construction are normal; their consequences need to be tracked. Revised glass, mechanical systems or materials may affect drawings, calculations and application information. Reviewing these together reduces the risk of using records from an earlier design as if they describe the final work. Shared, current information is central to coordination.
Include the handover to operations
Responsibilities that continue during occupation should be clear when the building is completed. The team should review the information handed to the operator and any open issues. This makes the operational implications of certification-related measures visible. Handover preparation requires more than placing files in a common folder.
AECO's YeS-Int consultancy considers scope, technical studies and coordination according to the project stage. Initial discussions can use building use, permit status and available project information to establish preparation suited to the authority's needs.
