Heat atlas - hand-out

Heat Atlases in Local Energy Planning
The demands are estimated based on a heat
demand model that uses building information:
•
• Year of construction
• Size of the building
• Type of building
The heat atlas also includes information about
current heat supply technology as well as heat
demand reduction potential for each building.

A heat atlas is a geographic representation of
heat demands typically related to buildings or
industries. Heat atlases exist in many forms
and on different levels of detail, from household level to city scale.
Application of Heat Atlases
Presently in Aalborg, we focus on:
The Danish Heat Atlas
In local energy planning, heat atlases are often
used to answer questions like:

What is a Heat Atlas?
Has been developed and used since 2008, and
estimates heat demands at individual building
level of all buildings in Denmark.
The primary use of heat atlases is to estimate
heat demands geographically. This is useful
for energy companies, researchers as well as
local authorities for making energy plans or
strategies.

•
•
How large are the heat demands?
What is the current heat supply?
Which district heating (DH) expansion
possibilities exist?
What are the possibilities of end-use heat
demand reductions?
Having geographically distributed heat demands, enables an assessment of technical solutions, like DH, that are very dependent on
the local geography.
So far existing analyses in development of renewable energy systems have been carried
out:
Expansion of DH systems and conversion
of natural gas areas
Exploration of new DH areas
Interconnection of DH systems
Mapping energy vulnerability
Assessing economic potentials for enduse efficiency
Current Focus
•
•
Improving the Danish Heat Atlas with
measured consumptions data from half of
the Danish buildings.
Looking into the possibilities of establishing heat atlases for areas in other countries. Also with a focus on the data requirements to establish heat atlases in varies contexts.

Recent studies
The TURAS Project Case Study

District Heating Potential in the

Heat Saving Potentials Copenhagen Energy Vision 2050
The current version of the Danish Heat Atlas
has been developed as part of the TURAS
project. In the project, the heat atlas was further used to assess different scenarios for renewable energy systems in the town of Aalborg.
The aim of this project was to develop a
screening tool for district heating potentials in
the Central Denmark Region. The potentials
were found by examining the economic cost
of expanding DH to individual heating solutions.
In a study of Copenhagen, the heat atlas was
used to estimate heat demands as well as reduction potentials in the end-use.
