The Blue Energy Library by our partner EA Systems Dresden GmbH is a commercially supported Modelica simulation library for modeling and analyzing complex, distributed energy systems. Designed for heating, cooling, power, buildings, mobility and storage technologies, Blue Energy provides ready-to-use, scalable, and customizable components to accelerate energy-system engineering workflows.

Seamlessly integrated into Modelon Impact, Blue Energy enables teams to design, simulate, and evaluate multi-energy solutions directly in the browser — with real-time collaboration across disciplines. From early concept studies to detailed system optimization, the combination of Blue Energy and Modelon Impact empowers you to validate designs, compare scenarios, and make informed decisions with confidence.

• Design and evaluation of interconnected energy systems (generator – storage – consumer)
• Optimization of control functions in energy systems
• Analysis of sector coupling (heating/cooling – electrical energy – mobility)
• Studying the interaction between energy supply and mobility requirements
• Model-predictive control

The Blue Energy Library incorporates more than 15 years of experience in energy systems simulation. It is continuously improved to deliver the best results for state-of-the-art engineering consulting. Available component models include:

• Heat exchangers, cooling towers, ground collectors
• Cost calculation

Combined Heat and Power Plant for a Building District

A simplified model of heat, warm water and electrical energy consumers supplied by a combined heat and power plant, with time-table-defined loads and a heat storage buffer for load peaks. The simulation reveals whether the plant can meet the electrical load continuously without additional electrical energy storage.

Multi-Zone Building with Electrical Vehicles

A building model with two thermal zones and an electric vehicle including its own charging station and battery. The model calculates the thermal behavior of the building through the balance of all heat quantities (transmission, internal loads, solar radiation). Electrical power is provided by a photovoltaic system and a small wind power plant. An air/water heat pump provides building heat.

Office Building with Ice Storage

An office building model with heating and cooling loads. A heat pump produces heat stored in a heat storage, as well as cold used for building cooling. The cooling energy is stored in an ice storage for seasonal use and a cold storage for short-term buffering.
