Architect · Energy consultant

Architecture,
building science
and the craft of construction.

I work at the point where design, material behaviour and on-site reality meet. My practice connects the cultural role of architecture with measurable building performance and the knowledge required to make details work.

“A building is not an object. It is an extension of the people who inhabit it.”

Design begins and ends with that relationship.

The approach

The architect–craftsman.

Architecture must survive contact with materials, trades, climate and daily use. Drawing and data are equally incomplete without construction.

The aim is not technical display. It is a coherent building: spatially precise, physically sound and genuinely supportive of the people who live within it.

Architecture

Spatial and technical design shaped by climate, use, local culture and the logic of construction.

Building science

Airtightness, ventilation, indoor air quality and building performance understood through measurement.

Materials & making

Materials considered through behaviour, compatibility, durability and the knowledge required to install them well.

Profile

A practice shaped between drawing and site.

Born in Berlin, educated in Genoa and specialised in building performance through CasaClima in Bolzano, I founded FUV in Athens in 2005.

My work has moved between architectural design, construction, material systems, retrofit, airtightness testing, ventilation and field research. This range is not a collection of separate services; it is one method for understanding the building as a whole.

First construction-site experience in Athens.

Diploma in Architecture, University of Genoa.

Founded FUV in Athens as an architecture and construction practice.

Qualified as a CasaClima energy consultant; FUV Products established.

CasaClima Gold project in Aegina recognised at the CasaClima Awards.

Authored AIVC VIP 45.7 on airtightness trends in Greece.

Joined the AIVC Board, representing Greece.

Field & research

Evidence before assertion.

Field work during Greece’s energy crisis sharpened a practical position: sustainability must be measurable, climate-aware, affordable and understandable to the people who use the building.

Through FUV, I have supported field measurements in homes and workplaces, examined the real behaviour of envelopes and materials, and translated that experience into construction decisions, technical education and international research.

Public knowledge · Since 2013

Technical knowledge, made accessible.

I founded FUV Channel and serve as its editorial lead and content creator. The independent technical platform translates construction, materials and building performance into reports, interviews and field-based stories.
