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??

Howcantheybeassessed?2• Questionaire

• 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

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
