What is NEB?ü Any real or perceived financial or intangible benefit received
from an energy efficiency activity.

• Industry juice production:• Energy comsumption:
• Electricity 10.000 MWh• Heavy fuel oil 43.000 MWh
• Proposals• Compressed air 750 MWh (elec.)• Cooling 635 MWh (elec.)• Lighting 235 MWh (elec.)• Process 3.500 MWh (h.f.o.)
• Is this the right focus??

• Change, with positive value
• Change, with negative value
• Change, don’t know value
Howcantheybeassessed?3• Calculation
• Identify and describe the benefits associated with a given measure
• Quantify the impacts
• Asses wich ones it is possible to put monetary value on
• Asses which ones has a positive, negative or neutral value

Industrialelectricity use forpumpsinDK10%
Savings due to lower cooling water temperature :153.000 kWh/year or 12.000 US dollar
However, ”what did the company achieve besides saving energy ?”Reduced:
• Use of chemicals 50.000 US dollar/year• Corrosion inhibitorer 12.000 US dollar/year• Reduced corrosion 20.000 US dollar/year• Reduced labour cost not calculated• Reduced down time not calculated• Reduced enviromental influence not calculated• Better working enviroment not calculated
•Pay back less than half a year

Introtoworkshops,sowhat happens ifyougofromhalogentoLEDintheKalkscheune?
What doyou achieve besides saving energy?
• Reduced maintenance LED life 25,000 hours, halogen 1,000 hours.
• Reduced procurement and installation costs.
• Reduced air-conditioning.
• Less heat from LED, less air-con leads to less energy consumed by air-con, less time for air-con means less
maintenance and extended life of air-con.
• LEDs reduce fire risk • May bee reduce insurance cost
• LEDs do not warm people up, which means people stay concentrated longer and more attentive. J
• LEDs give the Kalkscheune a green image
