A Commercial building
is:
A building greater >
1,000 square feet
With more than 1/2 of
their floor space
dedicated to activity
that is “work or office
related”
Commercial
buildings include,
but are not limited
to: stores, offices,
schools, churches,
gymnasiums,
libraries, museums,
hospitals, clinics,
warehouses, and
jails.

Energy Use in Commercial Building
http://www.energystar.gov/buildings/about-us/facts-and-stats
Combined annual energy costs for U.S. commercial buildings and industrial
facilities: $400 billion
Portion of energy in buildings used inefficiently or unnecessarily: 30 percent
Combined percentage of U.S. greenhouse gas emissions generated by
commercial buildings and industrial facilities: 45 percent
If the energy efficiency of commercial and industrial buildings improved by 10
percent, the collected savings would be:
Amount of money: $40 billion
Amount of greenhouse gas emissions prevented: equal to the emissions
from about 49 million vehicles – or about 19 percent of all registered
highway vehicles in the United States.

In 2005, the commercial sector
used an estimated 10.2 billion
gallons of water per day.
Three applications account for
88% of commercial building water
use: sanitary (e.g., toilets, sinks),
landscaping, and
heating and cooling.

Opportunities for Sustainability – Water
1. Low Flow fixtures
2. Grey Water
3. Rain Water harvesting*
4. Pressure Reduction (Booster)
5. Insulate piping - leaks
6. Leak Proofing
7. Rain Sensors
8. Cooling Tower Recovery*
9. Blowdown*
10. Education

Opportunities for Sustainability – Energy
Purchase energy from renewable
sources to reduce fossil fuel use
and emissions
Passive solar heating and
lighting, low emissivity
windows, structural insulating
panels, and energy efficient
landscaping
Renewable materials

Background
A very large commercial center had been using liquid water treatment products for many years in
its cooling system. The technical results had always been acceptable. In recent years, however,
the management team of the commercial center had become more and more focused on
environmental issues.
Blended solid concentrate water treatment products for their five cooling tower and
chillers, each with 1,000 tons of refrigeration, with slightly soft municipal water for
make-up.

Case Study
Impact
With the blended solid concentrate product implementation, cycles of concentration were increased
from 5 to 10, which enabled significant water savings and reduced chemical usage. The system
uses “bleed and feed” method to deliver the blended solid concentrate water treatment products.
