Abstract: This paper deals with the proper design and dimensioning of Domestic Hot Water (DHW) systems in residential care centres. A basis for the optimisation of the design is created through the development of a flexible and parametric simulation tool in Modelica that can be used in the design phase. An extensive design study and research into parameters and characteristics concerning the building, system and demand led to assumptions of average values and data to fill in the still unknown information at this stage of the design phase. Together with the integration of the general methods of dimensioning, the simulation tool can function with only a limited number of input data and is therefore optimal to be used in the design phase of DHW systems of residential care centres and, in extension, other public buildings. The design tool can have the potential to be of great importance in their optimisation and in the definition of energy-saving methodologies.
