Indoor Climate and Energy Tools

Welcome to the collection of freely available Indoor Climate and Energy Tools developed by the Institute for Energy Efficient Buildings and Indoor Climate at RWTH Aachen University. You are cordially invited to use the tools. Please do not hesitate to contact us for your feedback and contributions.

AHULife

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

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.

CityGML ADE Energy

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.

Teaser

TEASER (Tool for Energy Analysis and Simulation for Efficient Retrofit) allows fast generation of individual archetype buildings with low input requirements and the export of dynamic building simulation models for the AixLib and other open-source Modelica libraries.

uesgraphs

uesgraphs is a Python package to describe Urban Energy Systems and manage their data in a Python graph structure. uesgraphs can be used as a foundation to analyze energy network structures, evaluate district energy systems or generate simulation models.

NOODEL

NOODEL (33 NOde cOmfort moDEL) is a multi-node comfort model written in Modelica for predicting human comfort in various indoor situations. It consists of a thermophysiological body model and a psychological model.

BUDO Schema

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.
