The overarching Annex aim is to increase access to low-cost high-quality data from buildings and support the development of data-driven energy efficiency ‘Applications’ and analytics.
The objective is to achive proof of concept of a fixed bed CLC storage prototype using "green" ammonia obtained from wastewater streams by means of vacuum membrane distillation technology, as only fuel.
IEA IETS Annex XI pursues the goal of developing industrial solutions to achieve extensive decarbonization of various energy sectors through integrated biorefineries. Decision-making tools will be developed to support industry in the development of sustainable bio-economy strategies and to focus on reducing GHG emissions, considering circularity and using digitization to increase competitiveness.
The overall goal of the Solar Thermal Training Program is to contribute to the switch from a fossil fuel-based energy supply to a sustainable energy system based on renewable energies in general but on solar thermal in particular. In several theoretical and practical training lessons key experts were trained in the use of existing solar thermal technology.
Buildings and clusters of buildings may deliver energy flexibility services to different energy networks. This IEA project within the EBC technology collaboration programme will increase the knowledge about these services, as well as the barriers and motivation for the involved stakeholders.
The primary goal of this dissertation is a comprehensive analysis of the impact of building design parameters on energy flexibility. The thesis describes the future role of energy-flexibility of zero and plus-energy buildings as part of the overall energy system.
Extensive comparative study of of an infrared heating system (electric supply) vs. a radiator heating system (district heating supply) covering the aspects energy and primary energy greenhouse gas emissions, thermal comfort and economic efficiency.
Extensive integration of the different energy domains, in particular the electricity, district heating/cooling and gas networks, also referred to as hybrid energy systems, is a key element of decarbonization. The aim of the IEA DHC Annex TS3 is to highlight the potentials of district heating and cooling networks within a hybrid energy system while addressing the challenges.
The use of digital technologies enables an increase in intelligence, efficiency and reliability of energy systems. On the other hand, challenges such as data security, protection and ownership have to be addressed. The aim of the IEA DHC Annex TS4 is to present the current state of the art or the digitalization of the operation of district heating networks, to identify obstacles as well as to elaborate recommendations.
IEA SHC Task 62 addresses the integration of solar thermal energy into wastewater treatment in an industrial context.
