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-functionalcomponents

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 efficiencye.g. 51 stories > 3 floors more space (4.500 m 2)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

•……..

Use of daylight – energy efficient artificial light

• HVAC systems

• Elevators

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
