2.2 Modular Sequential Approach
Building up the roadmap sequentially in modules
As shown in the above figure, the roadmap can be thought of in 2 stages, including:
First stage:
Paving the way
– is the preparation work necessary before the extensive physical
changes in achieving significant energy reduction, this includes initiatives such as reporting,
benchmarking, legislation, and assessment. A comparatively small portion of energy reduction
occurs at this first stage, but at the same time, also requires relatively little investment in
resources; and
Second stage:
Realising Change
– with the ground work of the first stage in place, Hong Kong
will be ready to tackle the tougher problems of significantly improving the operation (i.e. retro-
commissioning) and hardware (i.e. retrofitting) of our buildings. The majority of the energy
reduction will occur in this stage with accompanying significant investment in resources.
