25 Degrees in Africa Volume 6, Number 2 - 2 May 2011
Camco, an international company specialising in climate change solutions, and Trade & Industrial Policy Strategies (TIPS), an independent economic policy research institution, recently released a case study entitled “The Construction Industry's Path towards a Low Carbon Trajectory” with funding from the British High Commission. According to the case study, the South African construction industry has been increasingly focused on both the introduction of green practices and on energy-saving technologies.
Globally, the building sector is said to contribute more than one-third of the total energy usage and associated greenhouse gas (GHG) emissions in society. Major South African construction companies, such as Group Five and Murray & Roberts, are starting to pursue green practices and projects. This has, in some cases, involved voluntary compliance with the Green Building Council of South Africa's (GBCSA) Green Star South Africa Office rating tool and the implementation of energy-efficiency and demand side management measures.
Recent media reports have also indicated that some construction companies (including Group Five and Aveng) are moving quite discernibly into renewable energy (RE) developments in the hope that they can secure a share of the renewables allocation under the Integrated Resource Plan (IRP) for electricity. In this regard, Group Five has set up a specific new unit which deals with RE projects and Aveng has recently appointed an environmental manager for the group. Aveng is particularly positioning itself around wind and solar energy for bids that will emerge in this sector in the near future. Murray & Roberts have also adopted a new environment-friendly asphalt technology (Much Asphalt) that saves energy.
