Two Savings Analysis Tools

An important function as part of the sales process is project payback analysis. Some energy management companies have developed powerful, precise strategies and tools to perform energy savings analysis for their customers.

To that end, many will use one of two processes to estimate payback, each one appropriate for a specific need. The two processes are the QSA (Quick Savings Analysis) and the DSA (Detailed Savings Analysis).

Let’s take a look at each of these.


QSA, or Quick Savings Analysis, is a process used to estimate HVAC energy savings. Of the two processes, QSA and DSA, QSA is the more common.

When is a QSA used? Sometimes they’re used as part of a project payback presentation.

So, in what situations will QSA’s be selected? It’s not uncommon for customers, presented with detailed quotes, to express the need to further understand project payback and savings. Highly sophisticated tools have been developed and mountains of data has been collected over years of energy management data collection.

The Quick Savings Analysis is the more abbreviated process and as the name implies, can be provided relatively quickly.


DSA stands for Detailed Savings Analysis. The DSA is less common than the QSA.

Unlike the QSA, the DSA is used not for estimating HVAC savings but for projecting HVAC savings. A typical requestor of a DSA is an energy rebate auditor. In most instances, when a property representative is applying for a utility incentive or rebate, a DSA plus a review of the DSA is required by the utility as part of the application.

The other typical request for a DSA is hotels at the brand-level. Sometimes when making a final decision on a major capital investment, the hotel brand requires a DSA for their own internal review before proceeding.
