However, a glance at planning offices, construction sites or discussions with craftsmen often reveals a different picture. This impression is confirmed by sober statistics: The construction industry accounts for a considerable share of energy and resource consumption.
The relationships between technical requirements, energy and material consumption and, of course, the function and esthetics of a building are complex. Which building materials are used, how many square meters of space are actually needed for what, and how much building technology is reasonable and necessary? Is a really required? Could car sharing be established for the building community instead of building parking spaces? Distinguishing between so-called greenwashing and truly sustainable solutions can sometimes be confusing and difficult. To come to promising building solutions and developments, all those involved in construction – architects and craftsmen as well as the construction industry – must continue to put common construction methods to the test and look for new ways to go.
