Taygun Yüksel

Founder, Sustainable Building Consultant

Taygun Yüksel has worked in sustainable building consultancy as the founder of AECO since 2018. His focus is on translating green building objectives into design decisions, technical studies and verifiable outcomes.

His approach considers certification strategy alongside building performance. Decisions on energy, water, daylight and indoor conditions are assessed against the project stage, intended use and available information.

Consultancy, auditing and certification assessment responsibilities are planned according to the relevant programme’s role requirements. Professional credentials support the establishment of an appropriate scope and allocation of responsibilities.

Where can we work together?

  • Green building consultancy: Coordinating LEED, WELL, EDGE and YeS-Int targets, project responsibilities and submission documents.
  • Building energy modelling: Comparing baseline and proposed designs and assessing envelope, lighting and mechanical system options.
  • Daylight simulation: Evaluating natural light distribution and design alternatives against visual comfort objectives.
  • Early design analysis: Using simple box analysis to compare the energy effects of design options.
  • Performance interpretation: Explaining calculated results alongside their methods, assumptions and measurement boundaries.

Your YeS-Int consultancy process is led directly by our founder Taygun Yüksel, who holds the YESU credential. Explore the YeS-Int service scope.

How we approach a project

  1. Define the decision: Establish the certification target, investment question or performance issue to address.
  2. Set the scope: Identify inputs, methods, deliverables and responsibilities across the team.
  3. Compare options: Assess results using consistent calculation conditions and explicit assumptions.
  4. Support action: Translate findings into usable recommendations for design, construction or operation.

The basis of a result should be clear. Calculated savings are distinguished from measured consumption, while energy consumption, costs and emissions are treated as separate measures.

Related work and an initial discussion

Explore the service scopes of completed and ongoing work in Our References. Energy modelling is also offered as a separate technical service where another firm leads LEED consultancy. The scope of daylight simulation is defined against project objectives.

For an initial discussion, share the building type, project stage, available drawings and the question you want the study to answer. The detailed scope, deliverables and programme are defined in a proposal based on that information.
