New market models for export of excess heat from buildings

Abstract

Office buildings, commercial buildings, IT centers, supermarkets, and hospitals may have excess heat from cooling equipment or some other processes. This heat may be used within the building or exported to the district heating network. Unfortunately, there are no clear requirements and rules to support export of the excess heat or cooling from the buildings. There are also some other practical issues related to the excess heat such as: reliability of heat delivery, heat measurements, and guaranty of desired parameters. However, few examples in Norway and Europa show that the excess heat will become an important player in the energy market. Therefore, it is important to identify technical and economical requirements that will enable a higher use of excess heat in the energy market.

In a previous master thesis a model for estimation of the excess heat from hospitals is developed. This model can be extend to test and give a critical view what market models may be suitable to enable cost-economical export of excess heat. Introducing simplified models for heat pump performance and waste heat estimation may be beneficial. Student can develop her work in Excel.
