• 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.
• AMT 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 aMT system with data
  from a Building Energy Management System (BEMS)
  to achieve intelligent reporting on a buildings
  energy and water consumption

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

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

How can you help?

• Turn off lights
• Turn off computers and monitors
• Turn off the tap
• Dont open windows when the radiators are on
  (turn down the radiator instead!)
• Remind others to do these things too!
