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

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
Intelligent Metering:
The whole picture
Intelligent Metering reports
• Provide:
– ‘Real-time’ reporting
– Clear building profile based on:
• Past 4 weeks data
• Normalised profile based on site survey results

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
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
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
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
What are the benefits?
•
•
•
•
•
Improved accuracy in billing
Energy cost savings
Reduced admin costs
Improve tendering / procurement process
Support centralised payment (future)
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
• Don’t open windows when the radiators are on
(turn down the radiator instead!)
• Remind others to do these things too!
