Energy demands

Energy demands represent energy use. For example, a building uses heat for heating and hot water, electricity for appliances and mobility, and cold for cooling. An energy demand can also represent an industrial process or the district heating network of an entire region. Energy demands shape the results, since every demand must be satisfied at every time step. For parameters, see Energy demands parameters.

An energy demand is a profile that specifies the energy consumption for every hour of a year — 8,760 hours, in kWh.

Make sure your custom profiles align with Sympheny's calendar year, which starts at 00:00 on Monday, January 1st and ends at 23:00 on December 31st. The year 2018 is a good reference, since it begins on a Monday and is not a leap year.

Tip

All profiles are clustered — a proven method for reducing solving time without affecting the results. Hourly profiles in the results may therefore not match the original energy demand profiles exactly. See Clustered profiles.
