Why retrofitting South Africa's buildings is key to a sustainable future?
In South Africa, where many commercial buildings, particularly in cities like Pretoria, Johannesburg, and Cape Town date back to the 1970s ,1980s or even older, retrofitting should enjoy priority. These ageing structures, often home to government offices or long-term tenants, are increasingly falling short of today's demands for comfort, energy performance, and environmental accountability. Furthermore, the idea that mostly well-built and completely habitable buildings are simply demolished is neither feasible nor financially viable. The greener and downright prudent alternative therefore lies in retrofitting; equipping these buildings with modern technologies that reduce energy consumption, improve tenant satisfaction, and future-proof these assets against rising utility costs and stricter carbon regulations. But why so modern? Today, older buildings mostly feature inefficient HVAC systems, poor insulation, and outdated lighting and metering infrastructure. As a result, building owners are left managing complaints around inconsistent temperatures, high operational costs, and growing vacancy rates. 'Thermal comfort' becomes a luxury instead of a standard, and tenants grow increasingly dissatisfied with spaces that are no longer fit for purpose. This is where smart Building Management Systems (BMS) and integrated energy platforms come into play. These systems offer centralised, data-driven control over HVAC, lighting, and energy monitoring, enabling real-time decision-making and predictive maintenance. A major plus is that these retrofits don't require tearing down concrete or rebuilding from scratch. As mentioned, many older buildings still have structurally sound foundations and facades. Preserving them means maintaining what is known as embodied carbon, the emissions produced during the original construction. Retrofitting also has multiple advantages beyond mere energy savings. It allows landlords, operators and owners to: - Reduce energy waste by installing unified HVAC and lighting systems. - Support predictive maintenance to lower long-term operational costs. - Ensure better air quality, especially in shared environments like hospitals or public offices. - Achieve green certifications through accurate digital monitoring, thus making buildings more appealing to tenants, investors, and environmentally conscious stakeholders. Tenant retention and value A modernised building is not just more efficient, it's more attractive. Energy-conscious tenants are increasingly drawn to spaces that align with their sustainability goals. Imagine walking into a reception with a Green Building Council certification, this immediately signals environmental credibility, which can influence leasing decisions and investor interest. Retrofitting also improves tenant retention. When facilities are comfortable, costs are predictable, and when systems are reliable, people are more likely to stay. This long-term occupancy protects the asset's value and enhances return on investment for property owners. Mitigating supply risk South Africa's unstable energy landscape adds urgency to this transformation. With unplanned outages, and load shedding a persistent reality, integrating renewables and improving building efficiency can significantly lessen pressure on the national grid and again, provide consistent supply to tenants. Retrofitted buildings that include solar panels, smart energy storage, and real-time monitoring can contribute to a more stable and resilient national energy mix. Importantly, South Africa's energy transition and climate commitments hinge on sectors like commercial real estate playing their part. Buildings worldwide are among the largest consumers of energy. Again retrofitting them is one of the quickest ways to drive down emissions without incurring the high environmental and financial costs of new construction.

Landlords face higher EPC bills as Labour's reforms kick in
Landlords could be forced to fork out hundreds more for energy performance certificates (EPCs) from Sunday as new rules come into force, experts have warned. Under reforms, energy assessors will be expected to use a new data collection system, raising the price of certificates to up to £250 each. The more stringent criteria could also mean that properties could drop an EPC band, experts said, making them impossible to let under rules set out by Ed Miliband, the Energy Secretary. Under the new methodology, assessors will be required to inspect the size, frame type and glazing of every window in the house more thoroughly, as well as recording any extractor fans and blocked chimneys. Chris Norris, of the National Residential Landlords Association (NRLA) property body, warned that the price of an EPC certificate, which typically costs between £50 and £120, could rise by £20 this summer as a result of the changes. He said: 'It's reasonable to assume that it will take assessors longer to take more precise measurements and input more specific data, so price rises are inevitable.' However, Sean Horton, of mortgage adviser Respect Mortgages, said the more intensive assessments could increase the price of certificates 'to £150-£250 easily'. He added: 'The window measurements alone are crackers. Instead of just noting 'typical double glazing,' assessors now need to measure each window individually, record orientations, frame types, glazing gaps, ages, draught proofing – the lot. 'That's going to make each assessment much longer, with the cost passed on to the landlord.' From 2030, all rental homes must have an EPC score of at least C, while landlords accepting new tenants will be expected to achieve the required standard by 2028. The plans are championed by Mr Miliband, who said it was a 'Tory scandal' that Britain's poorest households were living in 'cold, draughty homes', adding that 'many rent from private landlords, below decent standards'. But Anna Moore, of retrofit company, Domna, warned that the new system would likely result in many homes dropping an EPC band. She said: 'In particular, the model changes how electric heating systems are scored, intended to solve the problem of people installing heat pumps and then seeing their EPC go down. 'The new model also lowers the 'default assumptions' on carbon emissions in traditionally heated homes, so many properties will see their EPC drop. 'For example, a 1960s 90m² home, with empty cavity walls, might drop five points from EPC D to EPC E.' Labour is due to replace the beleaguered EPC system entirely with the much-anticipated Home Energy Model, following years of consultation. Among other changes, the reforms are expected to favour homes with the 'capacity to integrate with smart technology', which some fear will penalise homeowners who refuse a smart meter. Mr Norris, of the NRLA, said: 'When the Home Energy Model launches, the increases could be significantly more, depending on the outcome of the expected consultation into their methodology. 'While it is difficult to predict, it would not be unreasonable to expect that prices could double.' Kundan Bhaduri, of the Kushman Group real estate firm, said: 'For portfolio landlords, this is death by a thousand clipboard checks. 'Costs will rise sharply, and worse still, homes that previously scraped a C rating could now drop to a D, dragging us into yet another regulatory penalty zone. And this is just the warm-up act before the even more chaotic Home Energy Model arrives.' Many landlords are expected to sell up ahead of the changes, while others will be forced to spend thousands of pounds insulating properties or installing heat pumps to meet the required grade. Labour has floated a spending cap of £15,000 per property, and on Wednesday, Chancellor Rachel Reeves confirmed £13.2bn worth of funding for insulation upgrades. However, there are fears the cost of green improvements will ultimately be passed on to tenants in the form of higher rents. Research by Swedish bank, Handelsbanken, revealed 92pc of UK-based landlords believe tenants would pay more for greener homes. Tom Darling, of campaign group Generation Rent, urged the Government to impose rent caps on landlords who accept grants for eco upgrades. He said: 'With so many renters in fuel poverty, it's vital the Government is trying to make homes easier and cheaper to heat through higher energy efficiency standards. 'However, these plans must take place alongside amendments to the Renters' Rights Bill to protect renters from eviction and rent rises where public money has been used to improve a property. These grants aren't there for landlords to turn a dime off of.' A government spokesman said: 'Everyone deserves to live in a warm, comfortable home. We're investing £13.2bn in the Warm Homes Plan to upgrade five million homes over this Parliament, cutting energy bills for good through new insulation, solar panels and heat pumps. 'These long-planned changes make EPC assessments more thorough, giving people a clearer picture of how energy efficient their home is.'
