… AND WE ALL KNOW THIS:

Buildings contribute to 40% of global GHG emissions
1/3 of all waste generated in Europe
derives from the building industry
We need to rethink how we design, build
and deliver buildings!
OUR NEW WAY IS … GREEN BIM

• GreenBIM is being developed by Ramboll to incorporate the sustainability dimension into classic Building Information Modelling (BIM).
• The new tool provides a structured methodology for evaluating sustainability criteria on a continuous basis throughout a project.
• It facilitates improved interdisciplinary collaboration and thereby ensures that solutions are fully optimised and clients’ sustainability ambitions are realised.
• In addition, Green BIM provides clients with a documented and certified level of sustainability whilst also helping to achieve cost savings.
WE ALREADY KEEP MOST INFORMATION IN OUR BIM MODELS
GENERAL SCOPE OF THE TOOL IS TO ACCOMMODATE ALL WORKFLOWS

IDENTIFICATION OF THE KEY FUNCTIONALITIES
The initial technical functionalities were chosen as they;- have important impact in the design process- can be quantified through simulation tools, databases and calculations:
CO2 emissions [kg CO2 eq.]
Energy [kwh/m2/year]
Daylight Factor [%]
Thermal Comfort [°C], [°F], [PMV] or [PPD]
Life Cycle Cost [Currency/m2]
- Possible to reduce the CO2 emissions related to the building- Awareness and promotion of more sustainable solutions
- Enhancement of transparency of product data- Analysis – Comparison of different solutions
- Keeping track of the cost of the building project concerning initial construction, operation and maintenance
- Keeping track of the energy consumption of the building- Promotion of renewable energy sources
- Analysis of the amount of daylight in the building- Promotion of healthy indoor environment
- Keeping track of the thermal comfort of the building- Securing the desired indoor climate and comfort for the users

COMPARISON OF THE KEY FUNCTIONALITIES & EUROPEAN LEVELS
European Levels is an attempt to create a common language in EU and a tool to assess and report sustainability performance in the building sector.

MACRO-OBJECTIVES
GREEN BIM WILL BE BASED ON INTEGRATION WITH EXISTING TOOLS
Integration and/or interaction with existing tools used in Ramboll
The function will allow a smooth interaction with existing tools used by discipline specialist throughout Ramboll and across nationalities.
- Daylight simulation tool - Energy calculation tool- Structural calculation tool- Etc.
