Important information

Using the Heat Map

The heat map of Luxembourg is currently composed of 4 main layers: heat sources, heat sinks, distribution systems and background mapping.
The year the data refers to and the sources are indicated in brackets.
  • The layer “Heat sources” provides information on excess heat source locations and on temperature and energy quantity ranges.

Excess heat sources are subdivided into two main groups. Data based on literature review and entered by CRP Henri Tudor is displayed differently from data obtained directly from companies through an online questionnaire Data based on literature therefore needs to be confirmed or adapted by the actual company. 

The map also indicates sources where no excess heat is available for external users (for example, due to technical constraints that prevent heat recovery, processes that will change in the short or long term, or because the energy is already reused internally).
"Temperature and energy (2012)” provides more information on the temperature level and heat quantity of the sources. When this element is checked, by using the “Select” icon , as well as the relevant layer  , a table with the temperature and energy ranges is displayed when a source is clicked on.

  • The heat sinks layer is for thermal energy users. So far, a layer for household heat demand is published. This data is based on georeferenced data of building types (houses and residences) provided by the P&T. It also relies on statistical data provided by STATEC on specific heat demand, average building surface and numbers as well as age for each town. This approach implies that all houses and residences in one location have the same age and surface. While this leads to a certain imprecision at a very close range, the uncertainty of the energy balance for the town should be small. A paper describing the methodology will be published and made available on this site at a later stage.

 

  • Data on energy distribution systems is also provided. Currently, data on the natural gas grid of Luxembourg is available.
     
  • The background mapping provides general geographic information, such as the boundaries of Luxembourgish municipalities.


The transparency of the Topographic  Map layer, which shows the country in the background, can be decreased or increased by right-clicking “Topographic Map (2013)” on the right-hand side, selecting “Transparency” and moving the bar to the left or right.


At a later stage, the map may be further developed to include data on heating supply systems, district heating systems and heat users. For queries and comments, please send an email to heatmap@list.lu
