IEA DHC Annex XIII Project 07: CASCADE - A comprehensive toolbox for integrating low-temperature sub-networks in existing district heating networks
The majority of urban district heating networks operate at high temperatures, which are a barrier to the efficient integration of heat sources such as solar, geothermal, ambient or low temperature waste heat. CASCADE is investigating the integration of low-temperature networks into the return pipe of existing district heating networks, which will reduce return temperatures and thus improve efficiency and increase its capacity to connect new customers.
IEA DHC Annex XIV project 02 „FAST DHC - Feasibility Assessment Tool for District Heating and Cooling“
The transformation of district heating is referred to as the transition from the 1st to the 4th generation (4GDH). Recently, so-called ‘thermal source networks (TSN)’, also known as 5th generation or anergy networks, have been introduced. The aim of the project FAST DHC is to develop and demonstrate a simple tool for the techno-economic evaluation of 4GDH and thermal source networks, which also enables a comparison with individual heating and cooling solutions.
IEA DHC Annex XIV project 04: RE-PEAK - How to cover peak heat loads in DH networks with renewables?
One challenge for the decarbonisation of many district heating networks (DH) is the provision of peak load. The objectives of the RE-PEAK project are: to gain a better understanding of the specific problems, to collect empirical data on the provision of peak load, to analyse the perception of district heating network operators with regard to the transition to climate-neutral peak load coverage, and to consolidate the results and derive recommendations.
IEA DHC Annex XIV project 06: HY2HEAT Using electrolysis waste heat in district heating networks

IEA EBC Annex 55: Reliability of Energy Efficient Building Retrofitting - Probability Assessment of Performance & Cost (RAP-RETRO)
The scope of the project is to develop and provide decision support data and tools for energy retrofitting measures. The tools will be based on probabilistic methodologies for prediction of energy use, life cycle cost and functional performance. The impact of uncertainty on the performance and costs will be considered. Methods based on probability give powerful tools that can provide us with reliable ranges for the outcome.
IEA EBC Annex 66: Definition and Simulation of Occupant Behavior in Buildings
Given the considerable implications of occupants' presence and behavior for buildings’ performance, IEA EBC Annex 66 aims to set up a standard occupant behavior definition platform, establish a quantitative simulation methodology to model occupant behavior in buildings, and understand the influence of occupant behavior on building energy use and the indoor environment.
IEA EBC Annex 79: Occupant-Centric Building Design and Operation
The IEA EBC Annex 79 aims to provide new insights into comfort-related occupant behaviour in buildings and its impact on building energy performance as well as occupant-centric building design and operation.
IEA EBC Annex 83 - Positive Energy Districts
A positive energy district (PED) is an urban area/neighbourhood that is able to generate more energy than it consumes and is agile/flexible enough to respond to energy market fluctuations. This is where the IEA-Annex 83 and commissioned leading Austrian research institutions come in to collect, systematise, synthesise and process the knowledge and experience of the international scientific community on PEDs in a form that is understandable for practitioners.
IEA EBC Annex 84: Demand Management of Buildings in Thermal Networks
The concept of demand-side management (DSM) in buildings to reduce peak loads in the grid is well established in the power sector. The same concept can be applied to shift thermal loads in buildings connected to thermal networks. This project addresses the topic of demand response in buildings, focusing on the collection of case studies, technologies and collaboration models.
IEA EBC Annex 86: Energy Efficient Indoor Air Quality Management in Residential Buildings
Residential buildings should be able to provide good indoor air quality while ensuring high comfort and low energy use at lowest possible cost. This project will develop methods and compile data to evaluate different indoor air quality management strategies. Furthermore, innovative control strategies will be evaluated and tested in order to develop concrete recommendations for possible implementations of innovative ventilation systems for residential buildings.

IEA EBC Working Group on Cities and Communities (WGCC)
The WGCC enables information and experience exchange, the identification of bottlenecks that lead to specific research questions and a direct communication with cities on their needs, to enable them to transform their energy systems. The working group is a joint initiative across several TCPs with in-depth participation of technical and non-technical (external) experts.
IEA ES Annex 39: Large Thermal Energy Storages for District Heating
Large-scale heat storage systems will play a central role in increasing the necessary flexibility of district heating networks and enable the further expansion of renewable energies. The main objective of the Annex is to determine the aspects that are important in planning, decision-making and implementing large thermal energy storages for integration into district heating systems and for industrial processes, given the boundary conditions for different locations and different system configurations.
IEA ES Task 41: Economics of Energy Storage
What is the value of energy storage and how can it be quantified? How can the benefits and value of energy storage be translated into promising business models? The Task will conduct a coordinated methodological assessment of the economic viability of energy storage (electrical, thermal, and chemical) in applications relevant to the energy system. This will be used to derive preferred conditions for energy storage configurations.
IEA ES Task 43: Storage for renewables and flexibility through standardized use of building mass
Thermal building mass activation uses building masses to condition interior spaces, but can also function as energy storage through targeted overheating/undercooling. This storage potential can be used for local and grid-connected renewable thermal and electrical energy (Power2Heat). The project develops new content on the construction, control and business models of such storages and disseminates it as guidelines, data and on the basis of best-practice objects that have been implemented.
