The buildings of the education center Zofingen (Bildungscenter Zofingen BZZ) will undergo a complete renovation in stages until 2024. In particular, the 500 or so windows, sun protection and outdated building services, such as ventilation systems, emergency lighting, electrical distribution and building automation, are in poor condition and urgently need to be replaced. Important components are being renovated to improve energy efficiency. Replacing the windows will ensure better insulation and enable automatic summer night ventilation to cool the buildings without air conditioning.
