Stellenbosch University Admin B building is the first-ever EPC for a building in South Africa . maintaining a national Building Energy Performance Register , to keep track of progress towards the achievement of the goals and targets as set out in the EPC Regulations .
EPCs rate buildings ’ energy performance from A to G , with A being the most energy-efficient and G the worst , with D being the mid-point , when benchmarking against the average figures quoted in the national South African Building Standard SANS 10400-XA .
For the purposes of the EPC , a building ’ s energy performance is measured in terms of kilowatt hours per square metre per annum ( kWh / m 2 / pa ) of net floor area in accordance with the National EPC Standard , ( SANS 1544 ).
Barry Bredenkamp , SANEDI ’ s General Manager for Energy Efficiency & Corporate Communications , explains , “ Buildings must try and achieve at least a D-rating which is on par with the national benchmark . Their EPC must be displayed at the building entrance , no matter what their rating , in order to be compliant with the regulations .”
Bredenkamp continues saying , “ The regulations apply to nonresidential buildings ( specific occupancy classes ) with a net floor area of at least 2 000m 2 in the private sector , and 1 000m 2 for buildings owned , operated or occupied by an organ of state .”
Property owners and government entities have until 7 December 2022 to ensure that their buildings adhere to the regulations . Penalties for non-compliance have not yet been stipulated , and currently stand at the discretion of the Mineral Resources and Energy Minister , Mr Gwede Mantashe .
JP Spangenberg from EMVS says , “ South Africans should not see this as a punitive expense , but rather as the responsible thing to do in our commitment to address climate change and sustainability matters . EPCs are , in essence , a tool that gives clients a snapshot view of their building energy performance , empowering them to make informed decisions relating to energy efficiency improvements and renewable energy integration .”
Bredenkamp further notes , “ Stellenbosch University ’ s being awarded an A-rated EPC so soon after the regulations were gazetted , really is a phenomenal achievement and they should be applauded for this major step forward .”
Nadeem Gafieldien , Stellenbosch University ’ s Director of Property Services , passionately supports all efforts towards sustainability , “ Stellenbosch University is committed to the UN SDG ’ s and a sustainable future . While this EPC demonstrates this commitment , we are also in the process of certifying many of our buildings , using the Green Building Council ’ s neighbourhood tool in our efforts towards a Net Zero Carbon future .”
Bluedust Engineering Solutions ’ Dr Frank Duvenhage , says , “ This highlights Stellenbosch University ’ s continued efforts over the past few years to be more energy efficient and to respond with earnest to the repeated calls by government to use energy sparingly and to reach their goal of a net-zero carbon future . Hopefully , this achievement will encourage other building owners to follow suit !”
Bredenkamp concludes , “ The national drive towards energy efficiency will unlock the wider value chain , as building owners look to implement more efficient systems . Economic activity will be stimulated , as building owners work towards achieving compliance in areas such as HVAC , lighting , building retrofit , energy monitoring and more energy-efficient appliances and equipment , to optimise and reduce energy usage . This will involve engineering firms and other Energy Service Companies ( ESCos ), who will typically be contracted to do these energy efficiency upgrades , thereby creating much-needed job opportunities in the energy sector .” RACA
