Floridas economic growth owes a lot to air
conditioning

• Population growth, and the economic growth that
  came with it would have been severely curtailed
  if air conditioning did not exist to provide
  relief from the sweltering, humid, Florida
  summers.
• How do we keep growing and be green?

2
How important is A/C?

• 25 of all electricity used in Florida is
  exclusively for air conditioning and hot water in
  our homes. The demand for commercial cooling
  could represent 50 of all electrical usage in
  FL.

  2020.

What should qualify?

• Thermally driven Air-Conditioning, Heating,
  Dehumidification and Hot Water produced by
• Solar thermal
• Biofuels
• Concentrating, Combined Heat Power Solar
  Collectors
• Both thermal energy (heat) and electrical energy
  generated should qualify for incentives

Concerns? Impact?

• Absorption cooling is a mature, developed
  technology and available today.
• Currently in use in large buildings, college
  campuses and factories
• Changes are required in the mechanical
  infrastructure of homes and some building to use
  thermal energy produced.
• Solar thermal A/C works best when needed the most
  during peak demand times.

6
Impact? Reduction of Peak Demand

• Peak demand needs lots of peak power plants,
  which are costly to operate and raise electricity
  prices significantly.
• If you had to pay the 16,000 of electricity
  network infrastructure for your 2000 air
  conditioner, you may think again thats the
  case in Australia.
• Solar cooling can reduce the need for these power
  stations. Spain has a special rebate for Solar
  A/C, beyond what is given for flat plate
  collectors
• Spain believes that you absolutely need solar
  thermal to achieve Greenhouse Gas reductions.
• But when youve gone beyond Solar Hot water, then
  you need to tackle solar space heating. And as
  soon as you do space heating, youve got too much
  heat capture in summer, what to do with it?...
• Solution solar cooling. With of kW rebate, or
  a grant program.

Economics? Cost? of Solar A/C

• Solar Thermal Air-Conditioning provides three
  times the rate of return of solar photovoltaic.
• Each ton of Solar Powered Air-Conditioning built
  in Florida creates between 5,000 to 10,000 in
  new, additional construction revenues and 100
  per ton per year in maintenance services fees.
