Urban Wind Turbines
17
Wind Energy on Buildings

• Two main options
• 1. Small wind turbines mounted on top of
  buildings

18
Wind Energy on Buildings

• Or
• 2. Fully building integrated wind energy systems

19
Wind Energy on Buildings

• New area for wind energy
• Issues to consider
• Turbulence
• Wind speeds may be affected by buildings
• Vibrations
• Planning Issues
• Noise
• So what are the technologies available?

20
Types - Horizontal

• Advantages
• Efficient
• Proven to work
• Widely used many examples
• Most economic produces more energy
• Many products available UK and abroad

• Disadvantages
• Does not cope well with frequently changing wind
  direction
• Some say visually unappealing
• More noise

21
Types Vertical

• Advantages
• Less noise
• Wind direction immaterial
• Less sensitive to turbulent flows
• Creates fewer vibrations
• Some say easier to integrate into building
  architecture

• Disadvantages
• Comparatively uneconomic produces less energy
• Fewer models available
• Fewer working examples

22
Small Wind Turbines

• Horizontal

• Vertical

• In between?

Urban Wind Across Europe
30
Europe

• Small wind mainly for remote locations
• Few urban installations or manufacturers
• Exception The Netherlands at least 7
  manufacturers and many cities interested in
  installations

31
Canada, US, Japan

• Strong interest in small wind
• Canada - remote applications
• US - over 20 small wind turbine manufacturers
  mainly remote areas but also some suburban
• Japan many urban projects and products

32
Workshops coming up

• Economic aspects
• Technology installation costs cost per kW
  installed
• Factors affecting the economics of small wind
  turbines
• Potential future evolution of the costs
• Grid connection aspects
