Effektutjämning av Fjärrvärmelast genom att utnyttja Byggnaders Värmetröghet : En simuleringsstudie / Heat Load Balancing of District Heat Load by Using Thermal Inertia of Buildings : A simulation study

This thesis explores the potential of using building thermal inertia for thermal load balancing. It focuses on calculating time constants and determining the duration and amount of load that can be decreased in the building without the indoor temperature being decreased more than 0.5 degrees. Using data on residential area, construction year, building material, and supplied heat load, the study addresses the following main questions: calculating time constants for selected buildings, the quantities of supplied heat load that can be decreased, and over what duration of time, for the studied buildings.The method consisted of mapping a large amount of buildings from construction year, building material and relative heat demand to make a selection of buildings that were common and can be representative for more buildings. For each selected building the time constants and duration times were calculated. A model for heat load demand for space heating was made for each selected building to calculate the effect available for heat load balancing.Buildings with larger residential areas, higher heat demands per building, and lower heat demand per square meter exhibit significant potential for heat load balancing. The study identifies a newly constructed building with concrete structure and facade as having the highest thermal inertia. There is also potential for heat load balancing in larger, energy-efficient brick-built buildings.
