Green Buildings and Sustainable Development (LEED)

We live in a constantly changing world, with new challenges facing our generation. Global warming is a decades-long problem that has recently become an emergency. The COVID-19 pandemic, however, caught the whole world off guard.

Designing buildings under those circumstances requires changing the conventional way of thinking. The challenge is to design in new and innovative ways in order to build green, sustainable and affordable buildings, which promote conservation of energy and resources, and create a healthy environment for all building stakeholders.


Through our membership in U.S. Green Building Council, our LEED accredited engineers are able to continually explore new ways to incorporate LEED concepts in all of our designs, whether they pursue LEED certification or not. Our goal is to work closely with architects, owners and developers in order to find synergies in how different building systems can work together, so that we build more efficient buildings, with healthier and happier occupants, while lowering operational costs.


P-I Zannis & Associates is commited in delivering quality services, on time.

We accomplish this goal this by constantly updating our design processes, incorporating modern design methodologies, and upgrading our engineering software tools. We also emphasize educating our engineers on the latest technologies, through training programms and seminars from MEP equipment leading suppliers, so that they are always ahead of technological developments.

Chiller room

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.
