The Green Building Council of South Africa (GBCSA) offers a number of different training courses, seminars and workshops which are scheduled throughout the year. These give building industry professionals and other practitioners the opportunity to learn more about the Green Star SA certification process, the use of computer simulations in achieving Green Star SA certification, or the basics about green buildings and the Green Star SA tools currently available, among other related topics. All courses are validated for CPD (continuing professional development) points for architects and engineers. Towards the end of March the GBCSA is running a Green Star SA - Simulations and Submissions Seminar, a Green Star SA Project Certification Workshop and a Greening Commercial Interiors Workshop, in Johannesburg. The Green Star SA Accredited Professional Course will be run in April and May in four main centres: in Cape Town, 17 April; Johannesburg, 18 April; Bloemfontein, 19 April; and Port Elizabeth, 24 May.
