Integral Design


Vienna Engineers are following integral planning principles

Definition:  “Is a joint planning exercise that ensures participation of all stakeholders and affected departments. Its objective is to examine all economic,
social, and environmental costs and benefits, in order to determine the most appropriate option and to plan a sustainable building.”

Vienna Engineers work in each project in “integral planning teams” that are composed by experts from different disciplines, such as: architecture, construction engineering, building services engineering, electrical engineering, energy design and building physics.

Design teams are moderated by a coordinator of integral planning, to ensure a smooth planning process.

It is the quality of decisions that matters. Quality decisions will reduce conflicts and improve the local population’s identification with their surroundings.
Thus, our design teams assist our clients in finding the best options for them, their tenants, buyers and heirs.
