ETU Software

ABOUT US
ETU Software GmbH develops, sells and supports practical software tools in the fields of engineering, simulation, compliance-verification and financial justification of building services and renewable energy systems. Our software is used by architects, building services engineers and energy consultants. Today ETU Software GmbH is market leader many of those areas.

Heat pump
Design and simulation software for the design and optimisation of heat pump systems.

Basic function
Calculation of annual coefficient of performance (in accordance with VDI 4650) and simulation of seasonal performance
Calculations incorporating dual-rate electricity
Financial calculations including return on investment
Simulations of heating demand based on building characteristics, usage profiles and climate conditions
…

PV Simulation
Manufacturer-independent simulation software for the design and layout of photovoltaic systems

Basic function
Detailed analysis of roof layout, taking into account irradiation angle and roof lights, as well as shading factors such as dormers and chimneys
Dimensioned PV layout design in a 3D building model
Virtual simulation of shading factors such as neighbouring trees, buildings etc.
Calculation of multiple roof surfaces in one project
…

Optimus Duo
The Optimus* Duo program helps with the hydraulic balancing of retro-fit central heating systems. It is a must when renovating or expanding existing heating systems.

*The OPTIMUS methodology for hydraulic balancing of existing central heating systems was developed by ‘Ostfalia – Hochschule für angewandte Wissenschaften – FH Braunschweig/Wolfenbüttel’ under the supervision of Prof. Dr.-Ing. Dieter Wolff. See also:http://www.optimus-online.de

Building Simulation
The software simulates the thermal behaviour of a building at an hourly resolution. Accurate information about the behaviour of a building at any desired point in time can be calculated from the detailed building characteristics, usage profiles and location-specific climate data.
