WHAT HAS CHANGED?
Low hanging fruits are in the basket
Renewables are rapidly growing
Sustainable construction no longer a hot topic

Green building is big business
100 Green Building Councils
1.2 billion square meters of green building area registered with WGBC
Main driversclient and market demand
reduced operating costs
reputation and branding
Improved health and well-being linked to productivity

To do different thingswe need to do things differently (new process)
Before we can do things differently we need to think about them differently (new purpose)
Before we think differentlywe need to be different (being and becoming – express deeper values)

Building on existing knowledge
Making sense of the data Mining BIM and BMS data (ethically)
Integration made easy GIS and LCA info included in BIM models BMS and the Internet of Things
LCA for building materials Keeping things honest
Offsite construction

Challenges to inform new research
The climate map is changing what happens to performance of green buildings?How do we transfer learning between shifting climate zones?
How do we ‘measure’ regenerative/ contributive projects?Integrating across scales and cross-scale decision-makingAccommodating the expanded built environment teamThe soft issues: behaviour changes & values
