Green Buildings:
Delivering Energy Efficiency
Through Intelligent Controls

Green Building Definition
 Green building is the practice of increasing
the efficiency with which buildings and their
sites use and harvest energy, water, and
materials, and reducing building impacts on
human health and the environment, through
better sitting, design, construction, operation,
maintenance, and removal — the complete
building life cycle.
 Green building is also sometimes known as
sustainable building or environmental
building, although there are slight differences
in the definitions. The practice of green
building can lead to benefits including
reduced operating costs by increasing
productivity and using less energy and
water, improved public and occupant health
due to improved indoor air quality . . .

Energy Consumption Data
 Buildings represent 70% of U.S
energy consumption
 Energy consumption represents
30% of a typical commercial office
building’s operating costs
 A 30% in energy use can yield the
equivalent of a 5% increase in Net
Operating Income
 One of the strongest selling points
for green construction is reduced
operating costs from increased
energy efficiency

What Is An Integrated System?
 The ability to install products from multiple
vendors into a single cohesive system by
decoupling hardware from software.
