Heat Simulation for Building

Provided by: Orange Climate

With the Heat Simulation for Building tool, Orange Climate offers an easy to use, online and fast tool to calculate the impact of applying PCM in building concepts. In the background, the software calculates energy flows for transmission, solar irradiation, internal heat and HVAC against thermal mass and PCM application on a dynamic, minute per minute basis. This is being calculated based on the finite element model from Dr. Paassen, Delft University of Technology. With this tool, both parties with and without experience in building and HVAC design can get an understanding of the impact on comfort and energy by applying PCM concepts.

EnergyPlus™ is a whole building energy simulation program that engineers, architects, and researchers use to model both energy consumption – for heating, cooling, ventilation, lighting and plug and process loads – and water use in buildings. There are numerous features and capabilities available to tailor the simulation to your specific needs.

ESP-r (Environmental Systems Performance – Research) is a modelling tool for building performance simulation. In undertaking its assessments, the system is equipped to model heat, air, moisture, light and electrical power flow at user specified spatial and temporal resolution. The system is designed for the Linux operating system, but can also be run on Windows platforms both directly or within the Cygwin environment.

TRNSYS is a complete and extensible simulation environment for the transient simulation of thermal systems including multi-zone buildings.

It is used by engineers and researchers around the world to validate new energy concepts, from simple solar domestic hot water systems to the design and simulation of buildings and their equipment, including control strategies, occupant behaviour, alternative energy systems (wind, solar, photovoltaic, hydrogen systems), etc. Throughout its thirty year history TRNSYS has been under continual enhancement by an international group.
