• CORPORATE RESPONSIBILITY
• It has become very well known in todays
  environment that the conservation of
  non-renewable energy sources is essential for our
  energy future.
• Technology such as Melink Intelli-Hood has become
  leading edge in the fight to combat increasing
  the use of utilities and help offset greenhouse
  gas emissions.
• Canadas corporate companies are starting to
  realize this an make change effectively.
• Utilities such as Enbridge Gas, Union Gas, B.C.
  Hydro, Hydro Ottawa, to name a few are offering
  substantial incentive rebates and programs to
  help manage our ever increasing energy situation.

WHAT IS DEMAND VENTILATION?

• A Simple definition may read as follows
• Under partial cooking loads with no demand from
  the appliances, exhaust and make up air is
  reduced to preset acceptable minimum quantities
  and conversely increased when cooking load and
  appliance activity dictate.

COST IMPACTS ASSOCIATED WITH COMMERCIAL KITCHEN
VENTILATION

• Over 2 billion per year spent in the United
  States on energy consumption in commercial
  kitchens.
• In Canada, the number is close to 250 million.
• According to the Consortium for Energy
  Efficiency, with the addition of technology
  related to cooking, significant energy savings
  can be achieved.
• In a typical food service application, cooking
  accounts for 30 of utility use.

• ? Increases operating life expectancy of
  ventilation equipment
• ? Reduces maintenance costs
• ? Improves fire safety
• ? Improves occupant health
• ? Reduced noise levels - lends to a better
  working environment
• ? The use of demand ventilation helps contribute
  to the reduction of carbon dioxide emissions

• The cost savings with the Melink system are
  further illustrated by the following graphic
• MELINK ENERGY SAVINGS

• Existing conventional kitchen
• ventilation costs 14,664 per
• year for gas and electricity
• MELINK system in the same
• operation costs 5,324 per year
• for gas and electricity
• Savings are 9,340 per year
