We want to accomplish this because the current housing industry is responsible for the 30% of the national waste in The Netherlands, and nearly the 40% of its CO2 emissions. This numbers must change as soon as possible if we want, for example, meet the Paris agreement. However, this is not about meeting agreements, but about making this world a better place, or at least saving it from becoming a worse one. With CASA 1.0 we want to show that a more sustainable living is possible, being affordable as well as comfortable. We will show that it is possible to build a house using only biodegradable or recyclable materials, and even make it energy efficient by generating and storing energy. Last but not least, we want to show that the technology to make this happen is already created, and if a team of students can make it, what can an expert group do? Or what about an entire society?
