Drawing from our long and diverse experience in the design and implementation phases of MEP projects, we offer a complete range of services related to the field, such as:

  • Building MEP design and works supervision
  • MEP Infrastructure projects design and works supervision
  • Project Management
  • Cost/energy consumption analysis
  • Engineering consulting
  • Building permits
  • Feasibility studies
  • MEP design peer reviews
  • Building Energy Efficiency Certificates


We live in a constantly changing world, where technological advancement creates increased demands and vice versa. The challenge facing MEP design is to be able to meet these demands in new and innovative ways, while minimizing investment and life cycle costs, and also taking into account the effects on the environment.

P-I Zannis & Associates believes energy conservation is a vital part of any design, to the extent where it does not compromise functionality. This can be achieved by the use of renewable energy solutions, smart energy consumption automation and high efficiency equipment, and through the collaboration between architects, environmental and MEP engineers.


At P-I Zannis & Associates we strive to deliver quality services, on time.

We manage to achieve this by constantly updating our design processes, incorporating modern design methodologies, such as Building Information Modeling (BIM) - with the use of Autodesk REVIT - and by having the latest drafting and engineering specific software. We also give emphasis to educating our engineers in the latest technologies, through training and equipment supplier seminars, so that they are always ahead of the market.

But more importantly, we invest in people. We believe that close collaboration between our team and the client, architects, structural and other engineers is key to a more efficient workflow, which results in less complications during the construction phase, and a more satisfied client with greater control over the final budget.

Throughout the years we have had the pleasure of working together with the best known architects, structural engineering and also with other MEP engineering firms in Greece, in a number of exciting projects and have created lasting relationships, and opportunities for further cooperation in the future.

Finally, we are proud to be holding an EN ISO 9001 Quality Management Certificate for more than 15 years.
