“Smart City is more than the sum of its projects.
Rather, it needs a fertile environment guided by a clear vision,
the participation of relevant actors (people), and the efficient and
effective organisation of its processes (…)
Overall the case studies demonstrated that it is still early days for
truly Smart solutions (fully deployed initiatives with a strong ICT
component contributing to Europe 2020 targets).”

“ZEB has developed into an efficient research organization covering all
aspects of construction from materials research to planning, building and
societal aspects on developing minimized or zero emission buildings.
The cooperation within ZEB is unique and is well on its way in achieving
national and international recognition.”

«The climate impact of liberated electricity through energy efficiency is the
same as the effect of new electricity produced with renewable energy.
The combined architectural and technical measures are just as important as
solar cells.»
