Overview demand response types
Combining the two action and control types there can be four different demand response types: 1) Direct Automated (e.g. action and control types are characterised by high reliability; 2) Indirect Automated (e.g. model predictive control in the building reacting to the DHC broadcasted signal), action and control types are characterised by low & high reliability, respectively; 3) Direct Manual (e.g. DHC operator vising the house or sitting in the control room and pressing the button), action and control types are characterised by high & low reliability, respectively; 4) Indirect Manual (e.g. end users changing the settings physically of via using the remote technology (walking in the house, sitting on the sofa and using app) as the reaction to the broadcasted signal), action and control types are characterised by low reliability.

Combined building and plant simulation in real time
In a dynamic building simulation, the zones (rooms) are in contact with their surroundings and with the adjacent building components, the people, equipment and objects located in them. In the combined building and plant simulation, the dynamic interaction between building, plant and control is also taken into account. A building and plant simulation, adapted in real time to the actual weather conditions and current measurement data from the building, can help to optimize the control of the building services and thus reduce energy costs and increase user comfort.

Two Austrian demonstration building digital twin
In recent years, AEE INTEC has completed two projects for the development and initial implementation of a digital twin on real buildings in Austria. This digital twin is a detailed simulation model using IDA ICE software, which is compared in real time with measurement data from a real building. This creates a model that represents the real condition of the building and its building services at any given time. This model can then be used for automated fault detection or to optimize control systems. The aim is to reduce energy consumption and improve user comfort.

Organisation of the SIRFN network and technical topics in the project period 2021-2023
Overview of the organisation of the SIRFN network: The work programme for Annex 5 approved by the ISGAN Executive Committee (ExCo), the decision-making body within ISGAN, is divided into two sections, one dealing with the dissemination and exchange of knowledge and the other with the implementation of concrete projects for the further development of the research infrastructure.

SIRFN Focus Area: DER testing protocols
As part of the SIRFN focus are, SIRFN laboratories are developing test protocols for validating the interoperability of distributed energy resources, which can be used in an integrated test platform (System Validation Platform), for implementing a harmonised, international certification standard for all distributed energy resources in the power grids.

SIRFN focus area Advanced Laboratory Testing Methods
Within this SIRFN focus area, advanced methods for laboratory testing of components and electrical power systems are complemented by novel simulation technologies such as Power Hardware-in-the-Loop (PHIL), Controller Hardware-in-the-Loop (CHIL) and co-simulation, whose practical experience is however limited and not yet widespread. The SIRFN partner laboratories use their world-class research infrastructure to share expertise and jointly evaluate these new techniques, with the aim of establishing future test procedures within the framework of international standards, and provide recommendations for the optimal application of these techniques in laboratory environments.

SIRFN Partnerships and Stakeholders
As a global network, SIRFN also works intensively with partners from other relevant networks. These networks include research and development, industry and, in particular, the field of standardisation.

Scope of Resilience Definition
This figure illustrates the chosen framework for assessing the resilience of buildings. The definition focuses on building scale, with consideration of heat waves and power outages for a period of the next 100 years.
