Abstract
An integrated conceptual planning framework has
been developed to assist designing for high
resource efficient, low carbon urban district
heating systems. This paper focuses on
distribution energy losses of a district heating
system for an existing urban settlement. The
planning framework consists of a methodological
approach and a set of simulation tools to
investigate two scenarios – low temperature and
high temperature district heating networks. In this
framework a dynamic building simulation program
predicting energy demand of a case study area,
an industrial software tool for piping systems
design, and a mathematical optimization tool are
integrated for assessing energy and exergy
losses. Some preliminary results are shown at the
end of the paper demonstrating the benefits of low
temperature district heating networks and
potential of the planning framework
