Our roots

ALTO, musical instrument: the Opera of Bastille and the Opera of Lyon are the projects which led to the creation of ALTO Ingénierie. They gave us the passion and experience of major projects of public and cultural buildings.

ALTO, Auvergne wind : aerodynamics and energy are at the heart of our business.

AALTO Alvar, architect : the precursor of bioclimatic architecture. The creation of efficient buildings is our reason for being.

Our convictions

As an engineering  engaged since 20 years in the environmental quality of the building, we integrate this dimension in all our missions:

• Through a broader approach to engineering in terms of sustainable development;
• Through a decision support  upstream to possible projects by putting the physics of building and systems back into the heart of architectural design.

Our areas of intervention: Construction and land use planning

• As a project manager and assistant project management ;
• In France and abroad.
• The agencies of Lyon and Bordeaux develop and support our business in the region.
• The subsidiaries: ALTO Step (Bordeaux) expands our business in the territories and ALTO Medd Ingénierie (Nice) addresses the environmental problems of the Mediterranean climate.

Our slogan

«Let’s design the built environment of tomorrow».

With the challenging bet of building ALTO'Sphère, we decided to demonstrate by example. Confident and involved, we are determined to strengthen the role of ALTO Ingénierie in the engineering of environmental and energizing performance.

Together, we must invent high-performance solutions as soon as possible.
