In a suburban residential neighbourhood in Nyborg, Denmark, the real estate company Realdania Byg ? a subsidiary of the Danish Realdania Foundation ? has built six prototypical houses that are intended to pave the way to a future in which energy-efficient building will become standard and other essential aspects of sustainable construction will also finally be addressed. Among other things, this includes the use of recycled materials, durable and maintenance-friendly construction techniques, as well as the consideration of user behaviour.
Five of the six ‘Mini CO2 Houses’ are dedicated specifically to one aspect of energy efficiency. The sixth house combines – as a kind of marketable synthesis – many of the features proven successful in the other buildings. The budget for each house was limited to 1.7 million Danish crowns, which is approximately 230,000 euros.
In order to check the effectiveness of the projects, Realdania Byg commissioned two life cycle assessments for each house – one for an observation period of 50 years and the other for a period 120 years.
