Title: ’Cool heat grids’  for sustainable urban energy systems

By Sabine Jansen; Assistant Professor faculty of Architecture and the built environment

This lunch lecture presents ongoing projects on (ultra) low temperature heat grids for sustainable urban or neighbourhood energy systems, as one of the sustainable alternatives for heating with natural gas.

In the built environment, many heat sources are available at temperatures between 15 and 30 degrees, such as for example waste water, surface water, cooling from supermarkets or datacentres, and solar thermal energy. Also, the heating and cooling demand of buildings exist in this temperature range, or can make use of these low temperature sources by upgrading the heat with a heat pump.  In this lecture two projects on this topic are presented. The ‘KoWaNet’ project (www.kowanet.nl) aims at developing smart thermal heat grids that intelligently connect all these sources and demands. These smart and open ‘cool heat grids’ will optimally connect all users – producers, consumers and those that do both – in order to efficiently deliver sustainable, economic and secure heat or cold to its customers. The second – recently granted - project is on low temperature feed-in solar heat grids. This energy concept will be briefly explained and the influence of the insulation level of the connected buildings will be discussed.

Sabine Jansen works as assistant professor at the faculty of Architecture at Delft University of Technology since 2014. She is involved in education on sustainable energy systems as well as various research projects related to the energy transition for the built environment. She graduated from the same faculty in 2002.  After several years of experience at various engineering consultancies, she received her PhD degree in 2013 on the application of the exergy concept to energy systems in the built environment.

At the moment she focuses on two research topics:  bringing innovative and future-proof energy solutions into practice, and integrating circularity into the challenge of the energy transition, which is actually a 'resource transition'.
