Investigation phase results

Buildings that have completed the Continuous Optimization program continue to show impressive results.

On average, buildings that completed the implementation phase show a 7.6% overall cost reduction on average, with a 1.6 year simple payback*.

For a more detailed look at the results, and a breakdown of the different building sectors, see program results [MS Excel, 50 KB].

What are operational savings?

Many of our customers are familiar with the term "re-commissioning", but are curious as to what exactly constitutes re-commissioning conservation measures, also known as operational savings measures.

The following table provides a list of the top ten measures found by the program's re-commissioning consultants:

Rank Measure

1

Reduce equipment runtime

2

Optimize economizer operation

3

Eliminate simultaneous heating and cooling

4

Optimize supply air temperature

5

Optimize zone / setback temperature set points

6

Eliminate unnecessary lighting hours

7

Optimize ventilation rates

8

Volume control for pumps and fans

9

Add / optimize chilled water temperature reset

10
