Buildings represent 39% of U.S.
primary Energy Use
Building Energy Consumption
represents 30% of a typical
commercial Office Building’s
Operating Costs
A 30% Reduction in Building
Energy Use can yield the
Equivalent of a 5% Increase in
Building Net Operating Income
One of the strongest Selling
Points for Green Buildings is the
reduced Operating Costs from
increased Energy Efficiency

Building Control Transformation – Benefits of System Integration
Source: LONMARK International
Value of intelligent Building Control Network
Control systems are more than a collection of subsystems that interact to sense, monitor, or
control. Integrating various subsystem components reduces energy demand, increases
responsiveness, and reduces overall system cost as well as complexity. Stand-alone,
single-source, locked-in system designs are out, multi-vendor, fully integrated, fair-bid
contracts of open systems are in. Most sought-after benefits are (1) open procurement, (2)
flexibility, (3) future-proofing, (4) sustainable design.

Change
Introduction of object-
oriented programming to
model building control
network configuration.
After
Deploying the object-
oriented DB resulted in:
• 6 months advantage
in time-to-market
• several years of saved
developer time
• Enablement of
implementing more

Agile Development
1. C, Java, C++
software
development kits
2. Integrated object
lifecycle
management
3. Multi-tier
(embedded,
client/server, app
server, cloud)
4. On the fly schema
versioning
Enhancement
In the event of a major
release with new
features, capabilities and
a new database schema,
the built-in tools of the
database automatically
migrate the installed
customer database, with
no database or
programming expertise
required by the customer
or service partner.
Administration
1. Object-oriented
database is
embedded for
seamless
deployment.
2. It requires no
database tools or
administration.
3. It has an automatic
schema modification
and data migration
capability which
makes it easy to
enhance/evolve the
control network.
