About Annex 84

In order to achieve the overarching Annex aim, the Annex has following specific objectives:

  • Provide knowledge on partners/actors involved in the energy chain and on collaboration models/instruments for successful demand management.
  • Classify, evaluate and provide design solutions for new and existing building heating and cooling installations for successful demand management in various DHC networks.
  • Develop methods and tools to utilize data form monitoring equipment (e.g. smart meters, sensors) for real-time data modelling of thermal DR potential in buildings and urban districts.
  • Provide knowledge from and drive adaptation and visualization of Annex results through case studies.

To address the specific Annex objectives the research and development work in the Annex will be divided into four subtasks:

  • Subtask A: Collaboration models - WHO
  • Subtask B: Technology at building level – HOW hardware
  • Subtask C: Methods and Tools – HOW software
  • Subtask D: Case studies

The results of the annex will be

  • Comprehensive knowledge about the actors involved in the demand response of building in thermal networks
  • Recommendations for promising collaboration models depending on building typology, local context, end-users’ expectations or requirements
  • Design guidelines for heating/cooling and DHW installations, thermal storage system, DHC substation, monitoring sensors and control units for various building and DHC types with specification of minimum technological requirements for enabling demand management beneficial for buildings in thermal networks
  • Data-driven algorithms for smart thermal operation of buildings in thermal networks
  • Overview of different case studies of demand management at either single technologies, buildings or DHC community level

Official deliverables will be following tchenical report:

  • Collaboration models – overview of involved actors, existing practices, potential barriers and limitations, and recommendation for promising solutions for different building typologies and local context (STA, STD)
  • Building technology for activation of the demand response in thermal networks - status, classification and development guidelines
  • Smart algorithms that realise the thermal DR potential in buildings by manipulating thermal actuators in building heating/cooling systems
  • Demand management of buildings in thermal networks – Case studies
