Energy Demands

Energy Demands represent the energy use. For example, a building will use heat for heating and hot water, electricity for appliances and mobility, as well as cold for cooling. An energy demand could represent an industrial process or the district heating network of an entire region. Energy demands shape the results, since every demand has to be satisfied for every time-step. For parameters, see the Energy Demands Parameters section.

An Energy Demand is a profile, specifying the energy consumption of every hour in a year. There are 8,760 hours in a year, and the units are 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, as it begins on a Monday and is not a leap year.

Tip: Keep in mind that all profiles will be clustered, this is a proven method to reduce solving time without impact on the results. But hourly profiles in the results may not match exactly the original Energy Demand profiles (see section Clustered profiles).
