Order Description
You must submit the spreadsheet and a word document which is linked using the improvement measure numbering.
A) Company description 100 words (0 marks)
B) Audit 1000 words [including 10 marks from the emailing process]
(46 marks)

C) Improvement measures

E1.1
E1.2
To
N3.3
Describe each measure in technical and financial detail so that a manager could act on the information. In the example spreadsheet there are spaces for a number of possible measures. If you wish to add a different category that is OK. There is no word limit for the description of measures, but you should be able to complete each measure in typically 200- 400 words, that is around 3000 words altogether for section C). You cannot make savings from salaries as this assignment is to show environmental improvements, and not necessarily from commercial improvements.

Low/no cost measures
You should complete up to three low cost, or no cost measures, such as good housekeeping or changing to low energy light bulbs.
[ Each low/no measure is worth up to 6 Marks]

Medium/high cost measures.
You should include at least four medium/high cost measures, such as replacing electric motors with high efficiency ones.
. [ Each medium/high measure is worth up to 7 Marks]
Label each measure for example “ L2.3 high” (46 marks)

D) Spreadsheet.

For a successful case study you must provide a three year spreadsheet, which starts with £0 and ends with a positive value but includes a reduction impact of the company and the obtaining of ISO14001. The strategy must be logical. Include a 30 word conclusion.

Measure E1.1 low
Fitting low energy light bulbs. As illustrated in the table below, compact fluorescent light bulbs emit the same light level as conventional tungsten filament bulbs but are much more efficient since they do not operate at high temperature in order to produce visible light. In the table below the calculation is done for a single bulb operating for 8000hours. Assuming that the company has 302 light bulbs, used for 8 hours per day, with 270 operational days per year, and that these are replaced by low energy ones as they fail after 1000hours,
Each day: number of bulb hours = 302*8 = 2416 hours, and so on average 2.416 bulbs would be replaced each day.
As each bulb lasts 1000hours, they last a maximum of 1000/8 = 125 days. Therefore after 125 days all of the old bulbs would have been replaced.
The extra cost of replacing old bulbs with compact fluorescents = 302*(£5.0-£0.5)=£1359

Daily savings when all are replaced = 302*8h*(0.1-0.02)kW*£0.12/kWh= £23.19

For the first year:
Starting with 302 old bulbs, and replacing them as they fail
0-125 days would be the replacement period. So an average of 67.5 days are spent with the compact fluorescents. Energy savings = 67.5* £23.19 = £1565.33
125-270 days would be the rest of the year, entirely using the compact fluorescents. Energy savings = 145*£23.19 = 3362.55
Total savings for the year = £1565.33+3362.55 = £4927.88

Net savings for the year = £4927.88-£1359.00 = £3568.88
