OUTLINE


• Trends in technology and energy innovation
• Commercial sector technology innovation

   >   Building
       B ildi envelope l
   >   Interior lighting
   >   HVAC
   >   Building controls
   >   Data centres
   >   Renewable generation
• Power Smart Demonstration
  Projects
TRENDS
SMART AND WIRELESS

• Advances in the IT industry are translating to the
  building
  b ildi sectort
• Networking and communications technologies are
  helping to reduce waste,
  improve efficiency, and
  enable changes in
  behaviour
• These advances are
  transforming everything
  from building controls, to
  the grid itself and soon
  even your appliances
TRENDS
TOWARD NET ZERO BUILDINGS


• We are moving beyond simply reducing energy use
  to buildings that produce energy
• Renewables and distributed generation will provide
             l to th   id
  new supply t the grid:
   >   Solar PV
   >   Wind
   >   Combined heat and power
   >   Energy storage
TRENDS
INTEGRATION AT LARGER SCALES

• Where we used to talk about integrated building
  d i          there i t lk of i t
  design, now th                      ti    t the
                     is talk f integration at th
  neighbourhood scale
• Larger scale presents
  opportunities for:
  > District energy
  > Capture sharing of
    waste heat
  > Building complete
    communities that
    minimize the need for
    travel
TRENDS
NEW BUSINESS MODELS


• New business models will be required to enable
  efficiency and conservation at these larger scales
• Need to overcome new barriers
          issues with sharing energy across property li
   > e.g. i       ith h i                         t lines
• News ways of financing and delivering energy
  efficiency services and getting technology into the
  market
TRENDS
IT S
IT’S STILL ABOUT PEOPLE


• However, many technologies have been “emerging”
  for years
• The technology part is easy; it’s the people part that
  i h d
  is hard
• Need to overcome the
  ingrained attitudes of
  designers, installers and
  users
EMERGING TECHNOLOGIES
   WHAT S
SO WHAT’S NEXT?
LIGHTING
WHITE LIGHT SOURCES

  shift
                     quality,
• Careful: product quality
  performance and reliability varies
  by manufacturer
LIGHTING
ORGANIC LEDs


• Organic LEDs are in development stage
• Organic semi-conductor compound on a surface such
  as glass or plastic film
• Potential to change
  the way we use light
             fixtures,
• Instead of fixtures
  almost any surface
  could produce light
        p          g
