1 Form and Energy Optimization of Plus Energy Office Buildings - Learnings from Powerhouse One PhD Fellow Andreas Eggertsen Teder The Research Center on Zero Emission Buildings WP-5 - NTNU Trondheim Form and Energy Optimization of Plus Energy Office Buildings 1.Conclusions 2.Project description Powerhouse One 3.BIM based bioclimatic design process 4.Further research Illustration Snøhetta/MIR 1

2 Conclusions Plus energy balance over a life cycle of 60 years including embodied energy, construction, operation*, and demolition demands a BIM based integrated bioclimatic design process to achieve optimal utilization of local renewable energy production. Tools and processes needs to be developed to ease evaluation of embodied energy as design parameter in the operative dialogue of the design team. * not inculding energy demand for technical equipment Form and Energy Optimization of Plus Energy Office Buildings 1. Conclusion 2.Project description 3. BIM based bioclimatic design process 4. Further research 2

3 Illustration Snøhetta/MIR Powerhouse is a building that during its lifecycle produces more renewable energy than it consumes for production of building materials, construction, operation and demolition of the building. 3
