Copernicus Climate Change Service Sustainable Asset Valuation (SAVi) of Paterson Park’s Building Infrastructure: City of Johannesburg (South Africa)

The report evaluates the Paterson Park Precinct's building infrastructure in Johannesburg, comparing a business-as-usual (BAU) scenario with a green building scenario across different climate pathways (RCP 2.6, 4.5, and 8.5). Using the SAVi tool and Copernicus Climate Change Service data, the analysis finds that green buildings significantly reduce life-cycle costs through lower energy and maintenance expenditures and reduced greenhouse gas emissions. Climate change primarily increases energy costs and GHG emissions for both scenarios, though the green design remains more cost-effective. Additionally, the report identifies solar PV installations as a highly profitable investment in South Africa, particularly when accounting for electricity price inflation.

• Green building designs result in significantly lower integrated life-cycle costs over 40 years compared to business-as-usual (BAU) designs. Under the RCP 2.6 scenario, the net life-cycle cost for BAU is ZAR 461,367,293, while the green scenario is ZAR 311,859,445, with savings driven by lower energy expenditure, maintenance costs, and GHG emissions.
• Climate change increases life-cycle costs for both building types, with the most significant impact seen in energy expenditures and the cost of greenhouse gas emissions. Under the RCP 8.5 scenario, the cost of the green design increases by 2.1%, while the BAU cost decreases by 1.2% because increased precipitation reduces irrigation costs.
• Solar photovoltaic (PV) installations are a worthwhile investment for buildings in South Africa, showing positive net present value (NPV) and internal rate of return (IRR) across all simulated scenarios. Profitability increases when accounting for an 8% annual inflation rate on electricity costs.
• The integration of Copernicus Climate Change Service (C3S) data allows for the simulation of specific climate impacts on infrastructure, such as the effect of temperature on energy consumption and labour productivity, and the effect of precipitation on irrigation needs.
