Sustainable Asset Valuation (SAVi) of Paterson Park's Building Infrastructure: City of Johannesburg (South Africa)
-
Over the life cycle of buildings, there are significant cost savings in energy and maintenance expenditures for green buildings.
-
Climate change has the largest impact on the cost of energy expenditures, under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 scenarios. It also increases the cost of greenhouse gas emissions further under both climate scenarios. This is the case in both the business-as-usual and green building scenarios.
-
Solar power generates a positive return on investment and is a worthwhile investment for buildings in South Africa, especially when taking into account rising electricity prices.
The Paterson Park Precinct project is part of Johannesburg's Corridors of Freedom Initiative, which seeks to improve social cohesion within the urban environment. Buildings (including social housing, sports facilities, and a recreational centre) are a core component of this project. The project is also part of the Global Environment Facility (GEF) Sustainable Cities Impact Program, which promotes holistic urban planning to maximize environmental and social benefits and avoid negative trade-offs. The Sustainable Asset Valuation (SAVi) application includes an economic and financial valuation of the Paterson Park Project – Buildings, a comparative economic and financial valuation of a building with higher energy and water efficiency requirements and a simulation of these values under different climate scenarios. The Copernicus Climate Change Service (C3S) data that was used for this assessment includes precipitation patterns, temperature changes, and heating and cooling degree days.

Richard Halsey: Revised electricity infrastructure plan must admit benefits of energy storage
As the government concludes a much-delayed revision of the Integrated Resource Plan (IRP) for electricity infrastructure there is one technology that can offer multiple benefits to SA's struggling power system and shouldn’t be underrepresented in the new proposal—energy storage. Strategically located energy storage can help optimise the use of the existing transmission grid. While this is just one of many benefits it can provide, it is an important one for the government to factor in when deciding how much storage capacity to procure at the national level.
