The integration of building services is an important aspect of the architect's planning. The design of supply lines and cycles within the building requires an understanding of the interconnections between supply and disposal related to the element of water. This primarily concerns the relationships between the individual cycle elements, from the supply of drinking water, the consumers in the house, and the disposal of wastewater to the recycling of wastewater. The topic of water conservation serves as an overarching framework. Topics include: requirements for drinking water supply connections and distribution networks within the house, wastewater disposal and utilization, management of rainwater, and resource-efficient practices.
