Identifying Opportunities
Where are we now?
What does good look like?
Where do we want to be?
How do we get there?
Where are the Opportunities?
Operations – Good housekeeping & maintenance
Technology - enhanced plant, controls, fabric
Behaviour – building users
Procurement – energy efficient options
Design and retrofit – design, specification, build
How do we identify the Opportunities?
Benchmarking
Metering and Monitoring
Surveying and auditing
Modelling and simulation
Benchmarking• Compare performance against similar buildings
• Ideally indicate typical and good performance
• An indicator of opportunity and size (target)
• Engagement tool – simple, recognised
• A starting point for opportunity
Benchmarking – Regulations
Regulations - Energy Performance Certificates
• Asset rating – build, sale or rent
• Energy Act – 2018 F&G unlettable
• Property owners need a strategy – existing & acquisitions - opportunities and costs of compliance and beyond

Regulations - Energy Performance Certificates

Display Energy Certificates – new opportunities
Surveys and Audits
Technical
Walk-around Management and
behaviour
Organisation level audits (procurement and behaviour)
Surveys and Audits – Regulatory requirements
• DEC Advisory Report
• EPC Recommendations Report
• Air conditioning inspections (>12kW)
• Building Regulations Part L – consequential improvements
• Energy Savings Opportunity Scheme (ESOS)
ESOS – The Regulations
ESOS – an opportunity
• Opportunity to find savings – size of the prize
• Organisational focus – support and engagement
• Site-based ‘hard’ evidence as a basis for action
• Typical savings identified 20-25% (5-15% no / low capital).
• Need a strategy - what you want from the assessment
• Your priorities, which buildings, what detail
• Minimum compliance or maximum benefit?
Other Regulations
• Zero carbon new buildings landscape 2019
• Metering
• Smart meters - all small non-domestic by 2020
• Sub metering – Part L – 90% energy to be metered by end use
• Opportunity area - performance gap
Building Energy Metering CIBSE TM39
• 4 year research programme
• Over 100 new build and retrofit
• 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

In Summary
• Increasing Regulator burden
• Provide a focus and an imperative
• Represent a basis for new action
• Can help to remove some of the barriers
• New opportunities to make them work for you
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.
