In order to ensure consistent high quality of constructions, it is necessary to meet a large number of requirements. These are coded according to EU priorities, EU directives, national laws, European and national standards and technical regulations (for example, technical standards).

In the field of construction, the EU regulation on construction products should be mentioned in this respect, which creates harmonized conditions for the marketing of construction products throughout the EU. Before the construction product is available on the EU market, a "declaration of performance" needs to be prepared. The EU Construction Products Regulation of 9 March 2011 also defines a basic requirement for structures that should be appropriate for their intended use as a whole and in its parts, taking into account, in particular, the health and safety of persons involved throughout the building life cycle. Structures must meet these basic requirements: mechanical strength and stability, fire protection, hygiene, health and environmental protection, safety and accessibility during use, sound insulation, energy saving and heat protection and sustainable use of natural resources.

Contrary to EU regulations, EU Directives are not directly effective and binding, but must be transposed by national law in order to be effective. Individual directives are implemented in individual Member States. However, where a directive requires the creation of special rights or obligations, national law intended to implement them should create specific rights or obligations.

In the field of construction, the EU Directive on buildings 2002/91 / EC on the energy performance of buildings, also known as the Energy Efficiency Directive or the EU Building Directive, should be mentioned. As about one third of energy consumption in the European Union expires in the construction sector (in space heating or cooling of space, water heating and lighting), the EU Buildings Directive aims to increase the energy performance of buildings. The EU has set itself the goal of saving 20% of primary energy consumption by 2020. In order to achieve this goal, it is necessary to reduce energy consumption in buildings in Europe.
