Building user’s aspect

users aspects


The concerns of building users – practically the children and parents, teachers, and the maintenance staff - are equally important as environmental or economic considerations. Ms. Dorottya Budai, teacher, and Mr. Ferenc Deák, caretaker of the Hétszínvirág kindergarten told on the challenges and disadvantages during and after the implementation. As the building was in normal use, it was challenging to coordinate the daily pedagogical work with the investment. The parallel works required high tolerance from the building users.

Thought, despite of all inconveniences during the works, the benefits in awareness raising and education of the children results in a positive balance of the project.

The presentations of the technical experts are available here and here.
