4.4 Evaluation – How Intelligent is an "Intelligent" building?

With a strong push towards intelligent buildings, there is an increased need to develop an
independent and unbiased mechanism to evaluate how "intelligent" a given building is within a set
of given attributes such as the individual systems and how well they are integrated.

There are a number of standard tools being used by different organizations to measure the
effectiveness of intelligent building technology
As an example, BIQ is part of an evolving set of self‐administered on line questions through which a
particular project can be given a standardized score. This score is intended to reflect the intelligence
of the building, which has little bearing on its energy efficiency. The original BIQ evaluation
addressed the intelligence as a result of the integration of the communication requirements, signals
and protocols. The evolving process is placing a much heavier emphasis on energy management
including the ability to select the lowest cost of energy, i.e., the ability to change energy sources as
a function of spot pricing and to evaluate the benefits accruing to the overall project.

Reports are generated which benchmark the different sub‐systems with recommendations for
improvement in multiple categories including communication systems; building automation;
annunciation, security and control systems; facility management applications; and building
structure and systems.

4.5 New business opportunities for the building sector and ICT industry

The expanded capabilities of smart services and the data they generate are ushering in a new era of
innovation and competitive advantages for building owners. Buildings that are operated efficiently,
at lower costs and reduced energy expenditures also enhance building tenant's satisfaction and
create new business opportunities for all.

City authorities should focus on innovation, policy, economy, and infrastructure matters to build a
strong framework to strengthen intelligent building initiatives so that they can gradually upgrade
pilot areas which will become models to be imitated on a wider scale. This will help them to
implement smart sustainable cities and buildings, in the next few years.
