The role of engineering investigation and design.

To achieve significant energy savings the engineer must become familiar with all of the operations of the plant and building which relate to the use of energy.

Among the activities to be undertaken are:

• Identifying individual loads and losses (summer & winter)
  • Steam losses boiler room
  • Steam losses distribution system
  • Steam process loads
  • Condensate return losses
  • Heating loads
  • Cooling loads
  • Refrigeration loads
  • Air compressor loads
  • Electrical loads and peak demand
    
• Measuring load profiles weekdays & weekends
  
• Determining equipment efficiency
  
• Highlighting areas for improvement
  
• Reviewing heat recovery potential
  
• Investigation co-generation possibilities
  
• Assessing metering and targeting
  
• Summarizing savings and payback for various projects
  
• Submitting preliminary design and cost estimates
  
• Creating the final design
  
• Preparing drawings and specifications
  
• Calling for bids
  
• Aiding in selecting suppliers and installation contractors
  
• Supervising installation
  
• Evaluating equipment performance
