you can compare buildings:

40 on Oak, Melrose Arch, Johannesburg No 2 Silo, V&A, Cape Town

Rating tools available from GBCSA:

Net Zero & Net Positive exists

also for Carbon, Waste & Ecology

Various Green Star standards are available from

the GBCSA catering for different elements of the

property sector and property cycle:

For new buildings & major refurbishments

(Design & As Built)

For existing buildings in operation (12 months

of operational data)

For interior fitouts of tenants

EWP (Energy Water Performance) is a tool that

allows existing office buildings to benchmark

themselves against the industry norm:

Requires 12 months of energy & water

consumption data

Normalises for vacancy, occupant density,

size, number of computers, weather

Score on a scale from 1-10, where 5 is

industry norm, and 10 is net zero / net positive

To achieve the EDGE standard, minimum savings of

20% in its three categories are required:

For new buildings &

major refurbishments

(Preliminary & Post

Construction)

Residential buildings only

in South Africa (other

building types elsewhere

in the world)

Net Zero / Net Positive Standard:

Available for Carbon (energy),

Water, Waste & Ecology

For new buildings, major refurbishments,

existing buildings in operation, tenants,

precincts

Leveraging off existing GBCSA standards, such

as Green Star, EWP and Edge where possible

Certification via existing tools or as stand alone

1. Efficiency

2. Onsite production

3. Offsite

WHY CERTIFY (NO LEGISLATION)

Third party independent

verification of the green

building credentials

Marketing opportunity

Market differentiation

Demonstrating leadership to

buyers & shareholders

Aligning business practices and

design to a set of best practice
