Edd:e Energy Consumption Report

Transcription

1 Produced by Gillian Elliott Utilitywise plc

2 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. CONTENTS Page 3 Overall Power on Site Page 4 to 9 Overall Power per Distribution Board Page 10 Summary If you have any questions/queries regarding to information provided please feel free to contact me on the details below and I will be more than happy to help.

3 OVERALL POWER ON SITE # Total Consumption 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 kWh s per day which is costing an average of per annum on out of hour s consumption. 3

4 OVERALL POWER PER DISTRIBUTION BOARD # Overall Power - DB2 - Main Switchroom # Overall Power - DB1 - Main Switch Room # Overall Power - DB4 - Inside Cuboard at Exit Door at Toilets # Unknown - DB3 - In Main Switchroom # Overall Power - Power MCB in Main Switchroom # Overall Power - DB4 - Inside Cuboard at exit door at toilets # Overall Power - DB # Overall Power - DB3 Main Switchroom 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

5 # S3 - Coldstore # R7 - Unit 8 Plate Lower # T6 - Unit 10 Well Bain Marie # S5 - Unit 10 Well Bain Marie # R2 - Toaster Oven 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 kWhs which produced kg 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

6 DB2 MAIN SWITCH ROOM WEEK VIEW # R17 - Unknown # T15 - E4 Lighting # R16 - E4 Lighting # T21 - E6 Lighting # S8 - E2 Lighting Firstly the unknown circuit at the top of the table is using kWhs 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 kWhs, producing kg of carbon emissions. 34% of the consumption on this board is being used out of hours; this is costing you on average 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

7 DB3 MAIN SWITCH ROOM WEEK VIEW # 73 - Fly Zappers/Alarm (Bug) # 54 - Convection Oven # 54 - Convection Oven # 54 - Convection Oven # 56 - Unknown 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? kWhs where consumed on this board and as a result produced kg 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

8 DB4 WEEK VIEW # S5 - Sockets for TV # R19 - Dishwasher # T19 - Dishwasher # R4 - Female Toilets # T3 - Male Toilets 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 kWhs, producing kg 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 , as I mentioned timers and good housekeeping would reduce this. 8

9 POWER MCB IN MAIN SWITCH ROOM WEEK VIEW # 30 - E8 Lighting # 27 - E7 Lighting # 35 - E9 Lighting # 34 - E9 Lighting # 38 - E10 Lighting Looking at the data gather the total consumption on this board was kWhs which produced kg 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 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

10 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.
