1 The role of DECs, ESOS and other Regulation in identifying energy saving opportunities Malcolm Hanna, Technical Director, National Energy Foundation Improving the use of energy in buildings

2 Regulatory framework CCL, CCAs, EUETS, CCL, EPBD, EPC, DEC, EED, ESOS, Building Regulations Part L, Zero carbon buildings, Planning requirements, Smart Metering, Green Deal, RO, FiT, RHI, ECAs, Climate Change Act, Electricity Market Reform, Mandatory Carbon Reporting Increase Energy Security Reduce UK emissions by 80% Reduce business energy demand Increase low carbon technology use Encourage business to manage environmental impact

3 Identifying Opportunities Where are we now? What does good look like? Where do we want to be? How do we get there?

4 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

5 How do we identify the Opportunities? Benchmarking Metering and Monitoring Surveying and auditing Modelling and simulation

6 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

7 Benchmarking – Regulations all air-conditioning systems over 12kW must be regularly inspected by an Energy Assessor

8 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

10 Regulations - Display Energy Certificates

12 Display Energy Certificates – new opportunities

13 Surveys and Audits Technical Walk-around Management and behaviour Organisation level audits (procurement and behaviour)

14 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)

15 ESOS – The Regulations

16 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?

17 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

18 4 year research programme Over 100 new build and retrofit Energy use 2.5 times predicted – and more Opportunities – Design and retrofit Credit: Technology Strategy Board (Innovate UK)

19 Ensure your building project is not only designed green but delivered green Save costs, energy and carbon Improve comfort Opportunities – Design and retrofit

20 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 https://connect.innovateuk.org/web/building-performance-evaluation

21 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

22 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.
