Introduction • MM&T • Metering • Monitoring • Analysis & Reporting
Introduction • Fiscal monitoring • Devolved budget • Things go wrong
Metering • What to measure • Technology
Metering – What to measure • Building Regulations • 90% to be accounted for • Risk • Ease of detection • Auto/Manual controls • Capacity • Cost • £4,000
Metering - Technology • Pulse • Optical • Meter download • Smart Meters • Signature Analysis
Monitoring • Collate data sources • Manual • Frequency • Accuracy • Utility data • Portable monitor • Communications methods
Monitoring - Communications • Hard wired • Telephone Line • BMS • Elec network • LAN • SMS/GSM • Radio
Analysis & Reporting • Principles • Targets • Reporting • Profile Analysis • Benchmarking • Software
Analysis & Reporting - Principles • Regular monitoring • Continuous records • Driving factors • Degree Days • Occupation • Regression analysis
Analysis & Reporting - Targets Intercept: Before = 225,000 kWh After = 235,000 kWh Saving = £10,000 pa
Analysis & Reporting - Profile Analysis • Helps to identify • Peak loads • Out of hours use • Recurring loads
Analysis & Reporting – Benchmarking • Published figures or comparison of similar buildings • Future savings potential identified to bring buildings to “good practice” • Target areas of need • Avoid over-investment • Compare buildings on same site/different sites
Analysis & Reporting – Benchmarking • Broad brush • Annual figures only • Often dated
Analysis & Reporting – Software • Hold data • Fiscal • Manual reads • ½ hourly • Selective regression analysis • Cusum • Overspend league table
Summary • Regular monitoring • Driving factors • Regression analysis • Overspend League Table • Benchmarking • Profiling • Action • Not just energy • Saving
