Cesar-Chavez--Details

 

The Cesar E. Chavez Memorial Building is a ten-story, 180,000 square foot facility that was originally constructed in 1984, and underwent a major renovation during 2009-2012. This renovation transformed this once overlooked federal building into a state-of-the-art, high-performing green building that received Leadership in Energy and Environmental Design (LEED) gold certification.

This building was upgraded to the Terlyn Cooling Tower Conservation Program as a result of the water savings accomplished at the Denver Federal Center Building.  The savings graph below represents the total cooling tower water usage for the months from the previous year to those same months the next year on the Terlyn Conservation Program. Each month on the Terlyn Conservation Program shows the actual water usage, as well as what the water usage was from the previous year during the same month. (represented by the lightly shaded portion on the right side of the bars).

Water savings are not as substantial as other buildings because of the small size of the tower, and the fact that this building is located in Denver, Colorado where there is no need to cool the building for six months out of the year.

However, upgrading to the Terlyn Program was still able to reduce this building’s total cooling tower water usage by 48.6%!

On first look, saving 48% of a cooling tower’s total water use is not possible with water treatment alone.  However, the fact is that this system was scaled up from previous water treatment that was causing the system to use more water.

The Terlyn Program slowly removes existing scale while online.  This slowly removed the existing scale deposits from the system in the first year of operation that were causing excess water use.  This is why the amount of water conserved is so much greater in the second and third year because all the previous scale was removed in the first year of operation.  Year two and three reflect efficient water use from a scale-free system.
