Thermal protection and energy economy in buildings - Part 3: Protection against moisture subject to climate conditions; Requirements and directions for design and construction
The document specifies hygrothermal requirements and instructions for planning and performance of buildings and building components. It defines hygrothermal physical quantities and specifies requirements to protection against surface condensation (external and internal surface condensation), protection against driving rain (stressing groups and a map showing the driving rain stressing areas in germany). It gives examples for calculation and a list of former hygrothermal physical quantities due to be replaced by standardized European and international symbols.#,,#
