Developing an Energy Management Plan for the Whole School
United Learning – 18th February 2015Malcolm Hanna, Technical Director
Improving the use of energy in buildings
National Energy Foundation (NEF)
The National Energy Foundation is an independent charity that has been at the forefront of improving the use of energy in buildings since 1988. We aim to give people, organisations and government the knowledge, support and inspiration they need to understand and improve the use of energy in buildings.

1. The Benefits of managing energy
• Financial
• Saves money ~ 25%
• Potential for new income (FiT, RHI)
• Environmental - reduce carbon emissions
• Reputational – enhancement for the
school
• Educational - opportunities to link with
curriculum
• Improve the learning environment –
comfort, health, productivity
2. The Whole School Approach
• Many stakeholders across
the school
• They have an impact and a
role to play
• Important to involve all
• Integrity of approach
• Maximum benefit
• Making chance to stick and
embed

Measure and Monitor
Gather key energy data (actual)Review regularlyCompare with previous data (last week / last year)Look for unexpected or exceptional use - investigate

5. Policy
• Senior support – head teacher /
governors
• Statement of commitment and
importance
• Objectives and targets
• Responsibilities and resources
• Review and reporting
• Launch and communication with Whole
School
6. Team
• Core
• Senior sponsor – Head teacher / Deputy
• Co-ordinator
• Site staff – site / school manager, facilities,
caretaker
• Teachers
• Bursar / finance manager, secretary
• Wider
• Governors / parents
• Students
• Suppliers – catering, cleaning, maintenance,
engineering
Key intervention areas
•Operations – Good housekeeping & maintenance
•Technology - enhanced plant and controls
•Behaviour – building users
•Curriculum – enhanced learning for pupils and staff
•Procurement – energy efficient options
•Design and retrofit – work with suppliers
7. Opportunities
• Energy surveys (technical)
• Monitoring and sub metering
• Performance testing (fabric and plant)
• Modelling - building and systems
• Walk-around audits and interviews
(behaviours, could involve students)
Assessing Opportunities – tools and techniques
• Match plant operation to occupancy profiles
• Check and optimise time control and set
points
• Review with building users regularly
• Catering operations

• Equipment type
• Efficiency and
performance
• Size (loading)
• Age and condition
• Control
• Alternatives – replace
or enhance
Opportunities – Technology
Focus and define key behaviours – culture,
communication, peer pressure
•Switch-off – Lighting, IT, other equipment
•Set points – Temperatures, (timers)
•Heat loss – Closing of doors and windows
•Reporting and action around issues and waste
•Feedback on progress
Opportunities – Behaviour
• A wide variety of teaching
resources on energy,
• Ashden - resources aimed to be
compatible with the curriculum
• The Pod (EDF) - online teaching
resources, developed by EDF Energy
• Alternative – teachers given time to
develop bespoke materials
Opportunities – Educational
Opportunities – Procurement
• Wide range of performances
• Consider running costs or lifecycle – energy,
maintenance, other
• Suppliers should be able to provide running
cost information
• Sources of help – ECA Technology List, Energy

• Over 100 new build projects
• Over 50 non-domestic studies
• Completion and early occupation / in-use
• 18 schools buildings; 5 university buildings
• Energy use 2.5 times predicted – and more
Opportunities – Design and retrofit

Ensure your building project is not only designed green but delivered green
Save costs, energy and carbonImprove comfort
Opportunities – Design and retrofit
Emerging themes
• Commissioning – no buildings fully commissioned
• Sub-meters – not functioning or understood
• BMS – training, complexity, functionality
• Controls – complexity and labelling
• Lighting – too much and inability to control
• Fabric performance – specification and build
• HVAC – integration and control of multiple systems
• Renewables – installation, operation and
maintenance

Implementing a plan
1. Gain senior support, highlight importance and governance
2. Define responsibilities – Team and co-ordinator
3. Gather and review energy data – benchmark and monitor
4. Policy and objectives established
5. Identify main energy users and opportunities
6. Prioritise projects and confirm targets (ease and effect)
7. Implement actions – tasks, responsibilities, deadlines
8. Regularly review and report progress
Support
• Salix finance (interest free loans)-
• The RE:FIT scheme supports the
deployment of ESCO models for
improving the energy performance of a
school
• Solar Schools - school can play host to
solar panels to deliver clean energy to
the buildings and benefit from income
