BOT Main Classes

bot:Elementbot:Zone

bot:Site bot:Building bot:Storey bot:Space

A spatial 3D division. An instance of bot:Zone can contain other bot:Zone instances, making it

possible to group or subdivide zones.

Zone Subclasses

Constituent of a construction entity with a characteristic technical function,

form or position

Conclusions

• Data model developed organically as project evolves

• Explicit information exchanges through all processes

• DEMO illustrates the ease of accessing the data

01Baggrund


Future work

• Post-processing of observations

• Use Linked Temperature Data Cube to pre-process the hourly, daily, weekly, monthly and annual min/max/avg temperatures explicitly

•Useinrealprojecttoexamineworkflowsandbenefits

• Development of dedicated tools for describing control strategies etc.

•Optimizecontrolofflowsystemsbasedonobservations

• Re-do thermal simulations with actual occupant loads and weather data
