A carnot cycle heat pump provies 90mj to a house maintained

In medium to low density housing areas in ViennaвЂ™s outer districts with more industry, a higher share of residential heating demand near the sources can be covered by waste heat within a 250 m distance. In high density housing areas, only a small share of the demand can be covered by waste heat supply even within 250 m distance from sources due to few companies which could provide waste heat. Merging supply and demand maps allows to quantify the residential heating demand coverage through local waste heat in the potential supply areas within different distance ranges and housing density classes. Heating demand is mapped based on floor space of the buildings by age class and building type. Waste heat share and temperature ranges is reviewed from literature. Employees per company serves as proxy data to allocate the heat volume. Heat requirements for manufacturing and service provision is explored and, based on the distribution of the companies within the city, mapped as waste heat sources. As no observation data about waste heat and detailed heating demand is available, this data is derived from proxy data for estimating waste heat reuse potential and residential heating demand patterns. The City of Vienna serves as a case study to explore potentials to improve the urban heat supply using waste heat as an additional energy source. This paper deals with climate change mitigation and addresses waste heat reuse as a measure which is until now considered only to a limited extent.
