1
Metering and Monitoring The Business Case. Implementing the project. Benefits – accurate data and data analysis. On-going challenges.
2
Business Case Mixed estate. Energy data manually collected. Invoices based on estimated usage. Step change – targets. Prioritised voluntary H/H meter installs. 96% of our total energy use captured.
3
Roll Out Logistical challenge. Info gathering: serial number / MPAN. Site access requirements, meter location etc. Health and Safety, asbestos register, RA and MS, installer competence and install standards. Shut down requirements – Electric CT or WC meters and Gas.
4
Benefits (accurate and timely data) Less time spent collecting and collating data – concentrate on data analysis and identifying opportunities. Accurate profile classes. We now pay the tariff that matches our usage. Less accrued expenditure due to accurate billing, better budget profiling. Remote sites: pumping stations / weirs etc…meter readings obtained without a site visit (saving mileage and staff time).
5
AMR – Monitoring and Targeting Benefits AMR is a powerful tool that you can use to monitor and target energy improvements at your site through looking at: Base Loads: How much energy is your site using when no-one is there (nights and weekends) ? Shoulder hours: Is there excessive consumption (gas heating) during the hours leading up to occupancy ? Spikes, Peaks and Troughs: Are there any unusual changes in consumption which may indicate faulty controls ? Occupancy: Compare consumption with your sites occupancy hours – is it a good fit ? Seasonal trends: Does space heating (electric or gas) compare with weather changes ? LETS TAKE A LOOK
6
Electric Weekend Use ? Overnight Use (7pm- 7am) Day usage (7am- 7pm) What equipment represents the sites overnight use - is it all critical, can I reduce through better controls or switch off altogether ? Why is my site using 75% electricity (compared to a normal working day) at weekends when no-one is there - can I reduce through better controls or switch off altogether ?
7
Gas (night and day use) Weekend Use ? Corrective Action – drop in overnight and day time use High weekend use is investigated (why is the building being heated when no-one is in). The controls are investigated. The heating controls are adjusted and the corrective action demonstrates the reduction in energy use.
8
Gas (24 hr period) Shoulder period (getting the building up to temperature) Drop off – heating is off and the building begins to cool. A day use chart helps identify how early the heating is coming on in order to get the building up to the desired temperature and how early it switched off in order to maintain. The curve represents the ideal. You would expect the Gas to be off during the night, before coming on around 6am and going off before 5pm. Outside the curve represents waste.
9
You can’t manage what your don’t know ! Pumping stations represent a third of carbon emissions; identify best practice (motors). Sub-metering – identify the energy efficiency of technological improvements i.e. lighting, air conditioning etc… Challenge: Embed data analysis into everyday building management, maintain awareness, share lessons learned and maintain momentum.
