How green is your building?
People often make vague references to how “green’ their building is. The Green Building Council of South Africa has a very comprehensive system of “star ratings” which definitively rate a building’s greenness. You may want to pressurize your employers to make sure their premises are green, We have worked through the Green Building Council’s thick manual and come up with this short list of questions you can ask your boss about the building in which you work:|
Management
|
|
Is there a building users guide explaining all aspects of how the building is best used to achieve green objectives? If not, when will there be one available?
|
|
Has an a air tightness test been carried out showing leakage rate of less than 15 cub m/hr/sqm at relative pressure of 50 Pa?
|
|

|
|
Does 60% or more of the usable area have a Daylight Factor of not less than 2% at desk height level under a uniform design sky?
|
|
Energy
|
|
Does the building comply with SANS 204: 2008 (Energy Efficiency in Buildings)?

For a Saturday morning, things were going pretty much as they usually do. My daughter’s under 10 hockey match at 8:30, a quick croissant and coffee in Parliament Street, then dashing through to Charlo or Lorraine or Summerstrand or wherever ever the birthday party/play date/guitar lessons were on that particular day. To be honest I can’t remember where I was on my way to, but I do remember a mild throbbing in my head recalling a particularly tasty Friday evening Merlot and I do remember that I drove past the site that Continental Tyres has been trying to rezone for the last two years. The land lies there, fallow, windswept and bare, offering no benefit, no opportunity and no hope. That’s probably why I hardly noticed it and why I certainly did not think of it at all again until I read Mandla Madwara speaking about it in the Herald this week.
