Table of Contents
Aadorf, Switzerland, April 11, 2025 – Plans to expand the Löhracker school system in Aadorf are facing unexpected cost increases due to stricter energy efficiency standards and complex construction statics.

Student Increase Spurs Expansion
Like many communities, Aadorf is experiencing a surge in student enrollment. The Aadorf school system anticipates adding eight new classes in the coming years, straining the capacity of existing facilities. The expansion of the Löhracker school complex aims to address this growing need.
Sustainability drives Up Expenses
Initial estimates in July 2024 placed the project cost at 25 million Swiss francs. Though, Aadorf school officials now say the final price tag will exceed that figure.Increased sustainability requirements are a significant factor. As the project’s inception, regulations concerning energy efficiency have become more stringent, elevating the building standard from “Minergie” to “Minergie Eco.”
Unstable Ground conditions Add Complexity
Geotechnical studies revealed the need for additional stabilization measures.To ensure the building’s structural integrity, engineers may need to use piles to support the construction in deeper soil layers. This requirement adds further complexity and expense to the project.
Traffic Concept and Inflation Contribute
A revised traffic concept also impacts the overall cost. The new building necessitates additional parking spaces and bicycle racks. Moreover, the project faces a reported 15% inflation in construction and material costs.
Project Timeline Remains on Schedule
Despite the financial challenges, the expansion project remains on schedule.Detailed planning is ongoing, and the final construction loan is expected to be defined before the summer break. A public vote on the proposal is scheduled for September. If approved, the two-year school expansion will commence in the summer of 2026.
