1. Kirklees Energy Management Toolbox David Thorpe / Tom Tolputt Design & Property Service Energy Unit

2. Introduction • Our Aims • Kirklees Energy Management Toolbox Overview • 3-in-1 Energy Surveys • Intelligent Metering • Building Energy Management System Upgrades • Centralised Billing • Website • Future Plans • How can you help?

3. Our Aims • Implement legislation • Contribute to a Low-Carbon Council • Get best value from energy services • Be an exemplar for energy management

4. Building Energy Management Systems What is a Building Energy Management System (BEMS)? • Heating • Hot Water • Ventilation • Timing, temperature, zones, alarms

5. A Trend IQ3 Building Energy Management System Inputs Analogue Temperature Pressure Humidity Digital Run / fault Pulsed Meters Outputs Logs Modulating or on/off valves Alarms PID Times maths Time control for boilers logic

6. What’s involved in the project? • £650k commitment • 140 sites upgrading to IP communication • Replacing obsolete IQ1 controllers • Improving software strategy • Building in scope for expansion

7. What are the benefits? • Maintain / improve past benefits • Accurate and reliable communication • Wider access for clients (Web) • Supports Intelligent Metering • Supports management of approximately £4 million of energy use

8. Kirklees 3-in-1 Energy Surveys • What is a 3-in-1 Energy Survey? A Complete, fully inclusive Energy Survey for a Public Building • Energy Investments • Display Energy Certificate (legislation) • Building Energy Profiling

9. 1. Energy Investments Identify new energy investment opportunities • Building Fabric • Building Services • Ancillary Equipment Make the most of past investments • Good Practices by Building Occupants • Maintenance and Fine Tuning

10. 2. Display Energy Certificate

11. What use is a Display Energy Certificate to building users? • Provides the building with • Legislative compliance – Display Energy Certificate and Advisory Report • Clear Performance Feedback • Year on Year Improvement • Accountability to the Public • Benchmark with Other Buildings

12. 3. Building Profiling

13. What is Intelligent Metering? Intelligent Metering is collection of a number of concepts: • AMR – Automatic Meter Reading • The means to remotely communicate to a Intelligent meter and retrieve recorded meter data using proprietary communication media. • AM&T – Automatic Monitoring and Targeting • The ability to evaluate and set the energy profile requirement of a building and monitor actual consumed energy against the determined profile. • Demand Management • The process of linking the aM&T system with data from a Building Energy Management System (BEMS) to achieve intelligent reporting on a building’s energy and water consumption

14. Intelligent Metering: The whole picture

15. Intelligent Metering reports • Provide: • ‘Real-time’ reporting • Clear building profile based on: • Past 4 weeks data • Normalised profile based on site survey results • Graph and table of energy or water consumption • Profile trace and alert levels • Indication of areas outside tolerance • Information on the potential Cost and Carbon Dioxide savings over the year

16. Example Reports

17. Understanding aMR Consumption Cost Day usage Night usage Half-hourly values

18. Good aMR Profile Good, consistent profile Small base load

19. Poor aMR Profile Irregularusage Very large base load

20. Understanding aM&T Alert limits Target usage Control limits

21. Good aM&T Profile Usage is mostly within limits

22. Poor aM&T Profile Frequent, excessive usage

25. What is happening in Kirklees • Initial roll-out to 100 buildings including Offices, Schools, Leisure Centres and Town Halls • Upgrade of Electricity, Gas and Water Meters and enabling works from September 2008 to October 2009 • Installation of equipment to begin in October 2009

26. What Benefits Will Intelligent Metering Provide? • Provision of half hourly data for gas, water and electricity • Proactive energy management, based on ‘real-time’ data • Automatic daily profiling of building energy requirements • Reliable and accurate billing for consumed energy, reducing the ‘estimated’ bills in the conventional billing service

27. What Benefits Will Intelligent Metering Provide? • Reduction of electricity, gas and water usage, costs and CO2 • Greater purchasing flexibility through accurate procurement forecasting • Compliance with legislation and Carbon forecasting for the Carbon Reduction Commitment • Helps to maintain a sustainable environment for our community through reduced carbon dioxide emissions

28. What is Centralised Billing? Utility Bills come to Central Point and checked for: • Accuracy • Continuous readings and dates • Correct tariffs • Reduced estimates • Identify increased usage / seasonal usage

29. What are the benefits? • Improved accuracy in billing • Energy cost savings • Reduced admin costs • Improve tendering / procurement process • Support centralised payment (future)

30. Future Plans • Energy Awareness Raising – supporting the Environment Unit • Supporting design teams • Continually improve BEMS • Further roll out of Intelligent Metering

32. How can you help? • Turn off lights • Turn off computers and monitors • Turn off the tap • Don’t open windows when the radiators are on (turn down the radiator instead!) • Remind others to do these things too!
