Energy-efficient construction means: Many topics and issues of building must be considered and decided already at the very beginning of a construction project. More than ever, the various participating planners engage with their planning. The same goes for the various later works and trades on site. This ist the only way to realize energy-efficient buildings. This is especially true in light of the planned for 2012, further raising the legal requirements in the EnEV 2012 and other regulations.
