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

3. Energy use in schools

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
