Hello!
I am Dr.-Ing. Süleyman Tiryaki, an academic of Turkish origin and a Berlin-based Energy Efficiency Expert. With extensive experience in both Germany and Turkey, I provide consulting and auditing services for residential, non-residential, and corporate buildings in the field of energy efficiency and renewable energy.

My professional journey began as a Visiting Researcher at BTU Cottbus, followed by many years of hands-on expertise in the renewable energy sector. This path enabled me to combine customer-focused solutions with independent and effective operations.

Today, through my own initiative, “Doktoring Consulting *DC”, I am building a resilient and trustworthy business model, centered on quality, reliability, and long-term client relationships. From small projects to large-scale initiatives, my focus is always on sustainable and impactful growth.

In addition, I carry out energy audits and analyses within companies and issue the Energy Efficient Workplace Certificate, helping organizations create greener, more sustainable workplaces. As a certified consultant recognized by KfW, DENA, and BAFA, I also provide advisory services for entrepreneurs who wish to invest in Germany by accessing KfW funding and grants.

Why work with me?

• Strong blend of academic knowledge and practical expertise

• Bridge between Germany and Turkey, facilitating cross-border projects

• Commitment to sustainability, trust, and high-quality results

What I offer:
