This module generates load profiles of demand for space heating and hot water generation for a selected region. It uses default load profiles for the residential and tertiary sector on NUTS2 level and scales it to a given demand in those sectors and provides the load profiles separated for space heating and hot water generation.
Calculation of heat demand load profiles for selected regions.
Residential heating factor
The residential heating demand is multiplied with this factor.
Tertiary heating factor
The tertiary heating demand is multiplied with this factor.
Residential hot water supply factor
The residential hot water demand is multiplied with this factor.
Tertiary hot water supply factor
The tertiary hot water demand is multiplied with this factor.
Heat demand by industry
Yearly heat demand by industry in selected area.
Heat demand by residential heating
Yearly heat required for residential heating in selected area.
Heat demand by residential warm water supply
Yearly heat required for residential warm water supply in selected area.
Heat demand by tertiary sector heating
Yearly heat required for tertiary sector heating in selected area.
Heat demand by tertiary sector warm water supply
Yearly heat required for tertiary sector warm water supply in selected area.
Total head demand
Yearly total heat required in selected area.

The x-axis represents time and the y-axis power. It can be helpful to hide certain sectors to better see others.
Corresponding load profiles are assigned to industrial sites, residential and tertiary buildings in the user selection.
Based on the gross floor area of residential buildings and their Nuts0 ID the energy used for warm water supply is computed with the following list. With the Nuts2 ID of a specific area a load profile is assigned. The residential hot water supply is multiplied with the residential hot water supply factor in case the user wants to adjust the value.
Specific energy per area for warm water supply in residential buildings in different countries
|Nuts0 ID||Warm water supply in kWh/m²/a|
The heat density for the residential sector is used. Since this dataset already contains the energy used for warm water, the previous computed warm water energy is substracted from it. Based on the Nuts2 ID a residential heating profile is assigned for each tile of the heat density in the user selection. The residential heating is multiplied with the residential heating factor in case the user wants to adjusts the value.
Similar to the residential warm water supply the energy needed is computed with a table. With the Nuts2 ID of a specific area a load profile is assigned. The tertiary warm water supply is multiplied with the tertiary hot water supply factor in case the user wants to adjusts the value.
Specific energy per area for warm water supply in tertiary buildings in different countries
|Nuts0 ID||Warm water supply in kWh/m²/a|
The tertiary heating is computed similar to the residential heating. The tertiary heating is multiplied with the tertiary heating factor in case the user wants to adjusts the value.
The heat demand by industry is looked up the industrial database and based on the Nuts0 ID and the subsector a load profile is assigned.
The five resulting profiles are added together in an absolute way.
The mentioned load profiles consist of 8760 points which represent the load for every hour of the 365 days. Further information about the load profiles can be found here. All load profiles are normalized so that the integral is equal to 1.
The heat sources are taken from the industrial database. Based on their excess heat, Nuts0 ID and industrial sector a load profile covering every hour of the year is created for each site.
The heat density residential sector and heat density non-residential sector are raster files which can be found here.
