Besondere Merkmale
Allgemein
The added value for the project lies above all in the integral cooperation between the project participants in the planning and construction process. The intensive involvement of the users, the objective evaluation of design variations, the optimization of the planning in the design and the accompanying review and documentation of the target qualities during the entire duration of the project are decisive factors for the construction of the sustainable educational building. Decisions could be made objectively by recognizing and evaluating conflicting objectives and preparing them as a basis for decision-making. This enabled the qualities to be optimized in a balanced relationship to one another.
The building project is characterized by very good functionality in line with the construction task, a high level of comfort, a balanced ecological balance, high energy efficiency and outstanding economic efficiency over the life cycle.
