5. Architecture
Typical Heat Bridges
external wall cut trough concrete ceiling, cantilevered main bodies (balconies)
attachments of all kinds
non-insulated wall coping in roof
slipped insulating layers, collapsed bulk insulations
window reveals and window connections, window shutter boxes
Installations, like pipe and wire ducts, integrated switchgear boxes etc.

Architecture
Zero-Emission-Factory
Walls and ceilings with timber-frame construction
70% energy being saved by high quality thermal insulation system and heat recovery of used air
Solar collectors and Photovoltaics supply 30% of the needs for current and heating
Using rapeseed oil for co-generation meets the remaining part of energy consumption
70% water consumption being saved in toilettes by vacuum drainage
Passive cooling
50 % power being saved by optimized utilization of daylight and power saving office equipments
20% less revolving stocks by a consumption oriented logistics strategy

12. Basics Of Energy Sensitive Construction
Architecture
Basics Of Energy Sensitive Construction
Object-oriented and integral design
Definition of the energetic requirements and demand on energy key values in a user requirement specification
Engineers‘ participation in planning at an early stage
Optimization in the different phases of planning
Continuous check of the results in each planning phase
Energetically optimized building concept
Compact parts of the building, i.e. smallest A / V- Ratio
Workspaces with big southward windows (external sun - protection)
Reduce heat bridges = continuous insulation
Mostly hermetic building shell (Blower-Test)
Ventilation with heat recovery
