Visdoe Equest Energyplus+Design Builder
IES Trnys others (HAP,Therm)
•Proficiency means > 3 years experience •Based on CVs of 20 participants who have registered till Nov 8
• Day 1
– Introduction to software capabilities
– Simulation for IDP, examples
– Quality assurance
– Technology sets
• Day 2
– Solar protection
– Natural ventilation & mass
– Advanced hybrid HVAC systems
• Compare softwares under different
criteria
• Incomplete analysis by nature
• Look at capabilities for Integrated Design
Process, early stage design concepts of
advanced systems
• Monthly balance – LESOSAI, ….
• Some of the dynamic building simulation programmes – Simplified
• Ecotect
– Complete detailed • Energyplus
• TRNSYS
• IDA-ICE
• IES-VE
– Manufacturer based programs • HAP
• Trace
• Public domain source code – Energyplus
• Well documented, tested
• Design Builder (Interface) – Graphical building interface
– CFD (validation …)
– HVAC interface still limited (need knowledge of input files to go further, cannot be taken back to Design Builder)
• Private source code – IES-VE
– TAS
• TRNSYS – System based, building integrated as a
component
– Modular • User written modules can be added
• Many additional modules available
• Many PhD, Master with a Trnsys routine as side product
• Good user forum
• Physically intuitive
• Danger of the freedom for the user
– Co-simulation possible (EES, Matlab, …)
– Well documented, validated
• Energyplus
• TRNSYS
• Spark
• Dymola
• Simulink
• Modelica
• IDA-ICE
• Equation more flexible
• Not sure to get a working model
• Normally much longer simulation time
