Please find enclosed the energy consumption report produced using data collected from the Edd:e system, which is currently installed at your site. For the purpose of this report I am going to be looking at the areas which I believe will need your attention to reduce the overall consumption. I will be looking at each distribution and working out an average cost and percentage of energy used out of hours. This report has been produced using a week view and day view of your consumption data.

OVERALL POWER ON SITE # Total Consumption 4378.659 2381.99 4378.659 2381.99 This site is open 07:00 till 21:00 Monday to Friday and 08:00 till 15:00 Saturdays; however, I am aware this may vary due to cleaners etc. On an average week the site (highlighted above) is running at an average of 18kWh base load. Does this base load need to be so high? This is something that I am going to be looking at in the report. I have reviewed the sites out of hours and base load which on average 29% of your daily consumption is being consumed outside of working hours. In numeric and cost terms (basing cost on an average 0.09 per kwh) your using 202.08kWh s per day which is costing an average of 4746.85 per annum on out of hour s consumption. 3
OVERALL POWER PER DISTRIBUTION BOARD # Overall Power - DB2 - Main Switchroom 1439.573 783.128 # Overall Power - DB1 - Main Switch Room 1400.344 761.787 # Overall Power - DB4 - Inside Cuboard at Exit Door at Toilets 452.952 246.406 # Unknown - DB3 - In Main Switchroom 346.725 188.618 # Overall Power - Power MCB in Main Switchroom 271.594 147.747 # Overall Power - DB4 - Inside Cuboard at exit door at toilets 248.671 135.277 # Overall Power - DB3 135.922 73.942 # Overall Power - DB3 Main Switchroom 82.897 45.096 4378.678 2382.001 DB1 MAIN SWITCH ROOM WEEK VIEW As you will be aware the table and graph above are showing us how the energy is spread across each board along with how much kwh s have been consumed. DB2 was the most consuming board on this week view, when I have looked at past reports and week views this was not always the case. As I have stated I am going to be looking at the overall consumption on site via distribution view, as there are a couple of boards labelled the same I am going to link them together for the purpose of this report. I will be listing on the table the top 5 circuits from each board however more information will be available from the ask-edd:e website. 4
# S3 - Coldstore 887.301 482.692 # R7 - Unit 8 Plate Lower 134.981 73.43 # T6 - Unit 10 Well Bain Marie 64.309 34.984 # S5 - Unit 10 Well Bain Marie 57.162 31.096 # R2 - Toaster Oven 56.768 30.882 As I expected the cold store circuit is at the top of the table, I appreciate this circuit may not be able to be powered down. I have also noticed that circuit R2 - Toaster Oven was left powered from 11 th January till the morning on 12 th January. Was there a reason for this or was this circuit left powered in error? The total consumption of this distribution board was 1400.341kWhs which produced 761.786kg of carbon emissions. Circuit R10 - Roudies Cafe was powered for a little while around 22:00; do you know what caused this? Also is there any way that the temperature of the coldstore could be altered? This would reduce the overall consumption on this circuit as it would not need to work as hard to get to the lowest temperature. 5
DB2 MAIN SWITCH ROOM WEEK VIEW # R17 - Unknown 819.654 445.892 # T15 - E4 Lighting 85.844 46.699 # R16 - E4 Lighting 76.112 41.405 # T21 - E6 Lighting 58.47 31.808 # S8 - E2 Lighting 54.105 29.433 Firstly the unknown circuit at the top of the table is using 733.81kWhs more than then the following lighting circuit, do you have any idea what this could be? All of the other circuits are powering down at some point during each day, therefore this also apply to the unknown circuit? During this week view the above circuits consumed 1439.566kWhs, producing 783.125kg of carbon emissions. 34% of the consumption on this board is being used out of hours; this is costing you on average 1788.99 per annum. Due to the descriptions being so brief it can be different to establish whether they need to run as much as they are currently, having said this I believe if the lights need to run like they are currently the fittings should be recognised whether they are energy efficient to reduce the total consumption, LED lights have proven to be a great way of doing so. 6
DB3 MAIN SWITCH ROOM WEEK VIEW # 73 - Fly Zappers/Alarm (Bug) 61.857 33.65 # 54 - Convection Oven 2 58.315 31.723 # 54 - Convection Oven 2 54.581 29.692 # 54 - Convection Oven 2 54.574 29.688 # 56 - Unknown 33.193 18.057 Circuit 73 - Fly Zappers/Alarm (Bug) is powered down for most days however the Edd:e system has indicated that this was left running from 10 th till close of business 11 th, again was there a reason for this or was this circuit left running in fault? 565.54kWhs where consumed on this board and as a result produced 307.649kg of carbon emissions. If the fly zappers had been left powered by mistake then a timer would help to control this and make certain the energy is not being used without reason. A lot of the circuits on this board are branded as unknown, these will need to be identified as soon as possible to gain full advantage of the Edd:e system. 7
DB4 WEEK VIEW # S5 - Sockets for TV 148.959 81.034 # R19 - Dishwasher 121.094 65.875 # T19 - Dishwasher 117.228 63.772 # R4 - Female Toilets 66.444 36.146 # T3 - Male Toilets 43.003 23.394 The circuits for the dishwashers are powered at nearly enough the same level through the week, as the site is closed on a Sunday and through the evenings should they really be powered? Also could circuit 55 Sockets for TV be switched off at the socket to stop the circuit using energy that might not be needed? In total this board consumed 701.618kWhs, producing 381.678kg of carbon emissions. I have noticed that the restaurant lighting was powered from 19:30 till around 22:45, was there a possibility that staff/guests were on site till this time? Could the dishwashers and socket for the TV be put on a timer to manage the flow of energy? 36% is being used out of hours and this is costing you on average 1000.00, as I mentioned timers and good housekeeping would reduce this. 8
POWER MCB IN MAIN SWITCH ROOM WEEK VIEW # 30 - E8 Lighting 46.244 25.157 # 27 - E7 Lighting 44.991 24.475 # 35 - E9 Lighting 27.196 14.795 # 34 - E9 Lighting 22.693 12.345 # 38 - E10 Lighting 22.466 12.222 Looking at the data gather the total consumption on this board was 271.591kWhs which produced 147.746kg of carbon emissions. The day view has given us a better picture of what is happening on a day to day basis. I do believe the green line which is labelled as 38 - E10 Lighting to be external lighting, if this is correct should the lighting be powered through the full evening? As foot flow is low around the hours of midnight till 06:00 could these be powered down at this time? Also circuit 36 - E9 Lighting was left powered till the following day. 32 - E8 Lighting was powered for a short while in the very early hours and running late in the evening at different times, this should be looked into as soon as possible. 9
SUMMARY In this report I have covered areas where I believe savings can be made on site and what alterations need to be implemented to get these savings, such as the following: Lighting Do the corridor/toilet lights need to be on for the duration of the day? Occupancy sensors would work well on some of the circuits; this will control the energy in and out of hours. The circuit names are very brief but looking at the week view I think external lights are running throughout the evening, can the on/off times be changed? Also, are the lighting fittings on site energy efficient? Without seeing what fittings they are I cannot say but this something that I would recommend you look into to guarantee you are getting the usage possible. Small Power Some of the small power circuits are running out of hours and over the course of some evenings, a timer would work well on this board to manage the energy usage. I believe that the TV is on standby and never fully switched off when not in use; can the socket that the TV is plugged into be turned off every evening? I am aware that some of the circuits may not be able to be switched off but if timers were fitted on some, you would notice a different on not only your overall consumption but also on your electricity bill. Another successful way of controlling the usage is placing Turn Me Off stickers above the sockets to try and encourage behavioural change amongst the workforce. Other Circuits I would like to suggest that the circuit validation is completed on site as I am not sure what these circuits could be. Once they are correctly identified then accurate advice can be made on the circuits. We will discover that by continuosly monitoring these areas and applying good housekeeping practices, energy consumption levels will be reduced. If you have any questions regarding any of the above or you would like me to monitor any specific areas in more detail, please don t hesitate to contact me and I will be more than happy to help.
