What can we learn from South Africa's journey of implementing national standards on Green Building Implementation and Energy Performance Certification?

1. World Energy Day – October 2018
Entrenching National Standards –
The Journey towards Green Building Implementation &
Energy Performance Certificates (EPC’s)
Lisa Reynolds
President SAEE Confederation

2. Mission of the SAEE Confederation
• The Southern African Energy Efficiency Confederation advocates
collaboration in the continuous improvement and implementation of
energy management in support of sustainable development among its
divisions, affiliates, members and energy consumers in general.
• It works with government, the private sector, research & education
institutions, other organisations and energy professionals through
information sharing, networking, sharing of best practice, recognition
awards and an annual conference and exhibition to support the Energy
Efficiency Strategy, Climate Change Mitigation and Socioeconomic
development in South Africa.

5. Energy Efficiency Journey

6. • National Development Plan (NDP)
• Department of Energy (DoE)
• National Energy Efficiency Strategy (NEES)
• Department of Public Works (DPW)
• Energy Performance Certificates for Government Buildings
• Green Building Framework Policy (National & Provincial)
• Department of Environmental Affairs (DEA)
• GHG reporting
• Carbon Tax
• Department of Science & Technology (DST)
• The State of Electrical Energy Efficiency in South Africa
Where are we now - Government

7. Strategies need Action Plans

8. • To promote energy efficiency as the 'first fuel' in driving
balanced, socially inclusive and environmentally sustainable
economic growth, boosting job creation and leading
technological innovation across the region
Energy efficiency is considered to be a hidden energy resource that should
be fully exploited before considering other sources as it takes less time to
implement, lasts longer and keeps producing without the negative effects of
generation.
NEES

9. • NBR-X = National Building Regulation – Sustainability
• NBR-XA = National Building Regulation – Energy Efficiency in
Buildings
• SANS 10400-XA = “Deemed-to-Satisfy” Standard for Energy
Efficiency in Buildings
• SANS 1544 = South African National Standard for Energy
Performance Certificates
Key

10. History of Energy Efficiency in Buildings

11. History of Energy Efficiency in Buildings
(ctd.)

12. • Minimum standards for new buildings
• Heating & cooling energy
• Rationale behind NBR-XA
• Hot water supply – biggest energy use (residential)
• Thermal comfort
• SANS 10400-XA
• Hot water addressed
• Biggest heat loss & gain through the roof = focus
• Introductory “passive design” principles
• Efficient lighting & fixed services
• Masonry walling performance just above BAU
National Building Regulation XA
SANS 10400-XA

13. • Draft stage
• Due for publication 1st half 2019
• Stricter energy performance criteria
• User friendly
• Next redraft in 5 years time
• Why redraft?
SANS 10400-XA – Version 2

14. National Development Plan (NDP)
“Progressively strengthen the
energy-efficiency criteria set out
in the South African National
Standard to achieve a zero-
carbon building standard by
2030”

2020 target (34% reduction)
2025 target (42% reduction)
8% reduction on previous allowance required every two years

16. Another challenge
Compliance to Regulation/Standards

17. Policy pathway: impacts into the future

18. C40 Cities’ Analysis

19. • Building Control Officers, Building Inspectors & Plans Examiners
not enforcing Regulation sufficiently
• Lack of understanding of performance criteria relating to
practical building inspection
• Need training
• Capacity building
Solution to Compliance

20. National Energy Efficiency Strategy

21. NEES - History

22. NEES Target Reduction

23. How do we achieve these targets?

24. 1% NEW BUILD & REFURBISHMENT
-----------------------------------------------------------------
99% EXISTING
NEEDING RETROFIT
-----------------------------------------------------------------

25. • SANS 1544 – Energy Performance Certificates
• Regulating EPC’s
• Mandatory for Government buildings greater than 1000m2
• Mandatory for Private Sector Buildings greater than 2000m2
• Set minimum level
• Job creation for Energy Auditors
• Building Performance Register
• 2 years to comply
• Valid for 5 years

26. Do EPC’s save energy?

27. Energy Performance Certificate

28. • No
• Set goals for levels of energy performance
• Retrofit of buildings
• New EPC
Do EPC’s save energy?

29. Sustainable Buildings

30. • Department of Public Works drafted Green Building Frame-work
Policy
• Signed by Minister
• National & Provincial frame-works
• Green Building Norms & Standards drafted
• Buildings equate to Green Star 4 star rating
• Green Procurement
• Green Leases
• Eco-labelled materials
