Course Contents 
DesignBuilder 3-Day Simulation Training 
 
The course is aimed at new and less experienced DesignBuilder simulation users. After this course, trainees will be able to: 
 
�         Enter building geometry either from scratch or from DXF, or other floor plan data, making best use of the DesignBuilder productivity features. 
�         Enter data on activity, building constructions, glazing, solar shading, schedules of building operation, lighting systems and HVAC systems. 
�         Create components and templates and import/export these between projects. 
�         Understand the various model options. 
�         Size heating and cooling systems using EnergyPlus. 
�         Run EnergyPlus simulations using real weather data and check building energy consumption, CO2 emissions, occupant comfort etc. 
�         Carry out daylighting and natural ventilation analyses. 
�         Work with Simple HVAC (Compact HVAC is not covered in detail). 
�         Export EnergyPlus IDF data for use outside DesignBuilder (the course does not cover working with EnergyPlus IDF data) 
�        Set up external CFD analyses from site data and internal analyses from models incorporating assemblies, run CFD simulations and review results. Understand how to set up models that will provide converged results.
