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

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 Modelling and simulation Metering and Monitoring Surveying and auditing

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

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

9 Regulations - Energy Performance Certificates Source : Bill Bordass based on data courtesy of the Better Buildings Partnership

10 Regulations - Display Energy Certificates

11 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 Building Energy Metering CIBSE TM39 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

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

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

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

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.
