Integral planning approach
• Definition of objectives
• Definition of usage functions - requirements
• Consider local conditions
• Zoning of layout
• Requirements building envelope
• Heating, cooling, ventilation concept
• Lighting concept
• Accoustic concept
• Life cycle analysis (LCA)
•
Using natural resources Muli-functional
components
Optimization daylight use Using natural ventilation

Energy supply concept

Local conditions- energy design

Energy concept – overall building

Requirements building envelope

Solar- and glare protection

Heating, cooling, ventilation concept
HCV –concept - floor level

ceiling – heating and cooling
concrete core activation
+ low supply temperature
+ heating and cooling, specially for cooling
+ high storage mass
+ high comfort
- acoustic, ceilings impossible
- slow reacting system
- base load coverage
capillary tube mats
suspended ceiling
heating and cooling – thermal radiative systems

Space efficiency – by advanced cooling technology

Advanced HVAC- Technology
- higher space / volume efficiency
e.g. 51 stories > 3 floors more space (4.500 m2)
increased rent 1.8 Mio. €/a
- more energy efficient
- better indoor environment quality
Benefit of space efficiency – office buildings

• window size – position and design
• glazing performance – day light factor
• moveable sun and glare screen
• controll of artificial lighting
•……..

Monitoring is a must!

Lessons learnt
Comprehensive Design - Operation
• Potential of 30 – 40 % energy savings by
optimization (operation)
• Keep the overall system design simple!
-> one space heating / cooling facility
• Commissioning and monitoring (first year)
absolute requested – also for common
commercial buildings
• No complicated control strategy!

Conclusion
Sustainability – not only green issues - also financial and
sociocultural aspects of a building
Holistic design approach – impact on the energy demand,
indoor environment quality, life cycle costs and space efficiency
Holistic design approach requires an integrated design team
Investment costs might be higher, but life cycle costs are
lower
Sustainable Building Certification support the holistic design
approach – quality control during design and construction
