10 4.) PROCESS THE INTEGRATED TEAM 10

11 5.) FEEDBACK: BIG CONSTRUCTION MANAGER: + No extra work. + Good teamwork on the concept of energy efficiency monitoring. + The integrated process supported the change from Department of Architecture to Department of Technical Sciences. + Major interest and engagement of the occupants of Department of Technical Sciences in the BIGMODERN program. Energy efficiency experts and architects worked closely together. The BIG construction management was not always informed about the results. Therefore limited impact of the construction management on BIGMODERN. 11

12 5.) FEEDBACK: BIG ASSET MANAGER: + The Integrated Process supported the change from Department of Architecture to Department of Technical Sciences. + Thermic and daylight simulations modified the concept of the building. Communication between Energy efficiency experts and BIG asset management was limited. 12

13 5.) FEEDBACK: ARCHITECT + Workflow with experts was excellent and helpful. + More experts to deal with (uni-admin, uni-tenants, e7, GEA, PHI). + Excellent teamwork. + Integrated Process encouraged optimization process. + Would do it again! A lot more work to do. Problems during commissioning the building. 13

14 6.) INTEGRATION CREATES INNOVATION 1. Innovative window 2. Innovative upper door Flow-Over 3. Innovative aluminum façade with wooden supporting structure, without thermal bridges. 4. Innovative automation system (DDC) 5. Light traps - glass walls to the corridors. 14

15 LESSONS LEARNED ID process must be communicated from the beginning to all partners, continuously. Changes must be communicated to the tenant and the occupants. There must be a contact person on tenant's side to communicate all informations and needs during the whole process to the occupants and vice versa. There is a strong need for a standardized commissioning process. 15
