Definition of a Commercial Building

http://www.eia.gov/consumption/commercial/reports/2012/preliminary/


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.

Current Water Use in Commercial Building - Hotel



Current Water Use in Commercial Building - Hospitals



Current Water Use in Commercial Building - Laundry



Current Water Use in Commercial Building - Groceries



So what is typical usage for a normal building on a typical day?


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

· COOLING TOWERS

· WATER COOLED CHILLERS

· HEAT EXCHANGERS

· USE EVAPORATIVE COOLING

AND USE:

· A LOT OF WATER

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.

Solution

Case Study


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.
