ENERGY PERFORMANCE CERTIFICATES
(EPC’s)
for
CERTAIN BUILDINGS in SOUTH AFRICA
3rd Workshop for Policy Makers on Solar Heat
Barry Bredenkamp
SANEDI
14 July 2021
The South African National Energy Development Institute
The National Energy Act, 2008 (Act No.
mandate
34 of 2008), Section 7 (2) provides for
SANEDI to direct, monitor and conduct
energy research and development, as
well as undertake measures to promote
energy efficiency throughout the
economy.

Why focus on EPCs?
Included in South Africa’s National Energy Efficiency Strategy, (NEES)
Regulatory/Market demands and International Trends
EPCs to be mandatory between 8 December 2020 and 7/12/2022
EPCs - Government imperative and transformation opportunity for the
Energy and Property Sectors in South Africa :-
– “You can’t manage what you can’t measure”
– Benchmarking exercise: Numbers needed for Building Energy Regulations
– Public Sector: buildings greater than 1000m2
– Private Sector: buildings greater than 2000m2
– Building types:
– Entertainment & Public Assembly
– Places of Instruction
– Offices
National Energy Efficiency Strategy, (2030)
Sector 2030 Target, (based on 2015) Examples of Actions
Economy-wide 29%
Industry & Mining 16% Energy management, Carbon Tax, 12L (incentive)
Residential 33% Building Standards, Appliance Labelling
Public Buildings 50% Building Standards, DPW Policy, Energy Performance
Certificates
Commercial 37% Building Standards, DPW Accord, Energy
Performance Certificates
Agriculture 30% Modernisation
Transport 39% Vehicle Efficiency Standards, Carbon Tax
Municipal Services 20% Energy Service Companies,
Power Sector-distribution non technical 8% Mandatory efficiency improvements, Cogeneration,
issues 0.5% Waste Heat Recovery
Another Reason: Lifecycle Costs of Buildings
Not Just State-Owned Buildings – It is also applicable to “Other” meaning “Private Sector Buildings as per the ACT”
The Applicable Standard: SANS 1544
SANS 1544: Which Buildings?
Existing buildings which have been in operation to meet a
particular need for a period of 2 years or longer, and which
have not been subject to a major renovation or change of
occupancy within the 2 years prior to the assessment period.
Based on Actual Energy Consumption!
Class of occupancy of building Description
Occupancy
A1 Occupancy where persons gather to
Entertainment and eat, drink, dance or participate in other
public assembly recreation.
A2 Occupancy where persons gather for
Theatrical and indoor the viewing of theatrical, operatic,
sport orchestral, choral, cinematographic or
sport performances.
A3 Occupancy where school children,
Places of instruction students or other persons assemble for
the purpose of tuition or learning.
G1 Occupancy comprising offices, banks,
Offices consulting rooms and other similar
usage.

Issuing the EPC To be done by a competent, accredited person Independent third party/ SANAS Accredited body SANS 1544: 4.4.1 All energy consumption data shall be assessed by a body that has been accredited by the relevant national body, i.e. SANAS and submitted to SANEDI, together with a copy of the EPC.

Reference Maximum Energy Consumption: SANS 10400XA Table 3
Basic Data Requirements
Anomalies: Unoccupied floor area Net floor area is “Normalised” for unoccupied floor areas Effective energy consumption = measured net energy consumption/ occupied net floor area Occupied net floor area = net floor area, minus the unoccupied floor area.
Anomalies 2: Mixed Occupancy
Any occupancy with less than 10% of net floor
area will be included in the dominant occupancy
– Unless the energy consumption is greater than 10%
of the total energy consumption
A pro-rated energy-consumption value will be
calculated for occupancies greater than 10% of
net floor area.Building Energy Performance Register, (BEPR) SANEDI to establish the National Building Energy Performance Register (BEPR), to record energy data from EPCs. Feedback loop into updating the SABS 10400-XA. Ensure transparency when selling or leasing properties. Data is confidential and used for analysis/ modelling, but obviously, the EPC Register will be public!

As at 15 July 2021CONCLUSION
EPCs provide a huge opportunity for:
– Job creation
– Training and Skills Development
– Identifying Energy Efficiency opportunities for ESCo’s
– Stimulating technology adoption, e.g. SMART-options & SSEG
– Ultimately contributing to a reduction in energy consumption
and Greenhouse Gas Emissions.
Inclusion of additional building categories and
tightening of the kWh/m criteria – still to be decided!
