Waste heat from mobile groups of people in energy system optimisation

Kurzfassung

The heat emitted by people indoors ranges from 70 W to 150 W, depending on the activity. This waste heat is taken into account in the design of cooling systems, but can also be used for heating. This article considers the control of mobile groups of people in an office building without fixed desks and in an airport in order with several waiting rooms, to optimise the use of their waste heat. A linear optimisation model based on oemof.solph is used for the calculation, which takes into account both the thermal inertia of the building and the ability to influence the movement of groups of people in the building within a given framework. This work presents the formulation of the model, explains the assumptions made and compares optimisation results with standard operation.
