Braam Basson – Aurecon satisfy City of Cape Town planning permission conditions relating to environmental management . The CEMP sets out the management actions required to either avoid , reduce , or mitigate negative construction-related impacts on the local environment . Ecosense provides an experienced environmental site manager who visits the site fortnightly and provides the construction team and municipality with feedback on compliance levels and recommendations for improvement where required . The Century City Square development was recently awarded a 4-Star Green Star – Custom Mixed-Use Design rating by the Green Building Council of South Africa — the first development in the Western Cape to achieve this .
What is a Green Star rating ?
The Green Building Council of South Africa explains the criteria for its rating process . Green Star SA Rating Tools look at many categories to assess the environmental impact of a project ’ s site selection , design , and construction . Points are awarded for each credit within an environmental category . A project cannot publicly claim a Green Star rating unless the Green Building Council of South Africa has certified the project . Green Star SA tools are developed using a consensus-based model , led by volunteer Technical Working Groups . Each rating tool has its own working group made up of technical experts and industry practitioners from the relevant market sector . Categories
• Management
• Indoor Environment Quality ( IEQ )
• Energy
• Transport
• Water
• Materials
• Land Use & Ecology
• Emissions
• Innovation
• Additional available category : Socio- Economic ( SEC )
Credits , weighting , and rating The categories are divided into specific credits for green building actions . All targeted credits in each category are assessed and a score is calculated . Green Star SA weighting factors are applied , and a Green Star SA rating is awarded . Around 70 – 80 % of the credits for each tool are core credits that are common to all tools . Weighting factors are specific to each different tool to reflect the distinct environmental concerns in different market sectors .
