Thanks to the seemingly infinite availability of fossil energies, contemporary architecture was able to cast off many constructional and technical limitations in the 20th century. Light, open floor plans and airy rooms were the main topics and buildings made out of steel and glass were developed everywhere. Today, we know that fossil energies are finite and are too valuable to use for heating buildings. “Architects from the 21st century don’t have to waive all artistic freedoms and achievements from the 20th century because we can effortlessly complement them with the
principles of energy efficiency, ecology and sustainability,” explains the Swiss architect Beat Kämpfen. Clear, modern design and resource-saving constructions perfectly complement each other in his architecture.
