Architecture is both the process and the product of planning, designing, and constructing buildings or any other structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.
Architects and engineers are among the most fortunate of men since they build their own monuments with public consent, public approval and often public money.
Nearly zero-energy buildings are a major element of European climate policy, and by 2021 every new building has to meet this standard. Hybrid systems that are 100 % renewables will help transform the heating and cooling market, providing improved efficiency and carbon dioxide reductions.
