Under AHULife, the Institute for Energy Efficient Buildings and Indoor Climate provides a tool for calculating the energy demand and life cycle costs of air handling units. The energy demand is simulated based on hourly resolved weather data and internal loads. The user can choose between various configuration options.
AixLib is an open-source Modelica model library for building performance simulations. It contains Modelica models for building envelope and HVAC equipment such as boiler, radiator, heat pump and CHP. Emerging out of the Institute’s needs in research and teaching, AixLib contains models of different level-of-detail. The library extends the collaboratively developed Annex60 library, which focuses on basic model.
This extension of the CityGML standard for urban information modeling as an Application Domain Extension (ADE) defines a data model for urban energy analyses, aiming to be a reference exchange data format between different urban modelling tools and databases. It has been developed by an international consortium of urban energy simulation experts.
The BUDO Schema (Buildings Unified Data point naming schema for Operation management) structures the designations of data points in the building in such a way that an operator and a machine can interpret them. This structured data can be used for error analysis, optimization or measure development with the help of artificial intelligence within a building energy system.
EHDO is a webtool supporting the planning process of complex energy supply systems. The tool has been developed by Institute for Energy Efficient Buildings and Indoor Climate at RWTH Aachen University for academic teaching. EHDO supports the planning of future energy supply systems and to estimate the potential of renewable energies and future energy carriers like hydrogen. A wide range of innovative technologies like fuel cell, electrolyzer, hydrogen storage, photovoltaic and wind turbines as well as biomass and waste-to-energy technologies can be considered in the tool.
