OpenGL building modeller allows building models to be assembled by
positioning 'blocks' in 3-D space. Blocks can be cut and stretched allowing
you to work with just about any geometry. |
 |
| |
Global changes can be made to the model at building, block or zone level. |
| |
Control the level of detail in each building model allowing the tool to be used effectively at any stage of the design or evaluation process. |
| |
Building geometry can be imported from CAD data and then traced over within DesignBuilder to create blocks and to partition blocks up into zones. |
| |
Generate impressive rendered images and movies of your building design including the effect of site shading. |
| |
Extensible architecture of the internal graphics engine will allow rapid development of the new modelling features which we have planned for future versions. |
| |
Environmental performance data is displayed without needing to run
external modules and import data and any simulations required to
generate the data are started automatically. |
 |
| |
EnergyPlus 'Compact HVAC' descriptions provide an easy way into detailed
analysis of commonly used heating and cooling systems. Choose from: |
| |
VAV with terminal reheat and options for VAV box and outside air control. |
| |
Constant volume. |
| |
Split air. |
| |
Fan coil units. |
| |
Packaged rooftop, unitary DX. |
| |
Hot water radiator. |
| |
Underfloor heating. |
|
| |
High temperature radiant heating. |
|
| |
All air systems can have recirculation with outside air control, economiser, fan and pump modelling. |
|
| |
Natural ventilation can be modelled with the option for windows to open based on a ventilation set point temperature, openings can be modulated by outside air temperature. |
|
| |
Daylighting - models lighting control systems in one or two lighting zones and calculates savings in electric lighting. Choose from stepped or continous dimming. |
|
| |
Shading by louvres, overhangs and sidefins as well as internal and mid pane blinds. |
|
| |
Model glazed cavities such as double facades and Trombe walls. |
|
| |
A comprehensive range of simulation data can be shown in annual, monthly, daily, hourly or sub-hourly intervals: |
|
| |
Energy consumption broken down by fuel and end-use. |
|
| |
Internal air, mean radiant and operative temperatures and humidity |
|
| |
Comfort output including temperature distribution curves, ASHRAE 55 comfort criteria, Fanger PMV, Pierce PMV ET, Pierce PMV SET, Pierce Discomfort Index (DISC), Pierce Thermal Sens. Index (TSENS), Kansas Uni TSV. |
|
| |
Site weather data |
|
| |
Heat transmission through building fabric including walls, roofs, infiltration, ventilation etc. |
|
| |
Heating and cooling loads. |
|
| |
CO2 generation. |
|
| |
Heating and cooling plant sizes can be calculated using design weather data. |
|
| |
Parametric analysis screens allow you to investigate the effect of variations in design parameters on a range of performance criteria. |
|
| |
Generate IDF files and work with these outside DesignBuilder to access system functionality not provided by DesignBuilder. |
|
| |
Choose from a range of different EnergyPlus simulators including the current DOE executable release, the current DLL release and any interim releases made available by DOE. |
|
| |
Latest ASHRAE worldwide design weather data and locations (4429 data sets) are included with the software and 1258 EnergyPlus hourly weather files are available free using the DesignBuilder 'Install on Demand' feature. |
| |
Data templates allow you to load common building constructions, activities, HVAC & lighting systems into your design by selecting from drop-down lists. |
| |
Add your own templates if you often work on similar types of buildings. |
| |
Realistic rendered images can be generated and exported from the model with no additional work. |
| |
Explore the model using simple view controls. |
| |
Site shading analysis for any day of the year. |
| |
AVI movies of solar shading and scene orbit automatically generated. |
|
|
| |
Colour-coded layout images show zone activites (usage). |
|
|
| |
Cut-away sections. |
