After completing a building in EQUEST, we can stimulate the file and find results for the single run, or we can run a comparison through the EEM Wizard. Please note the EEM Wizard is only accessible when in the Wizards, and not in detailed mode. Here we can click “finish,” and in the upper left we can click the energy efficiency measure wizard. Here we're going to compare a constant volume system verses a VAV system. Since multiple items are changing, select whole site building and select okay. This takes us to the EEM Wizard with one additional run. 

Here, if we want to complete a life cycle cost analysis, we can first enter the project and baseline run data. In this case, we're running a roof top unit, so the number of analysis here is going to go to 15. We're going to assume that the roof tops have a life of 15 years. We enter our other parameters, such as federal income tax. We can also specify the discount rate if we assumed different values than the defaults. We can also assume uniform price escalation rates, or inflation rates, of electricity, and a second fuel over the life cycle. In this case we'll leave it at none. 

Finally, we can specify the first cost of the baseline run. In this case, we're going to say 100,000 dollars with an annual maintenance cost of 5,000 dollars. We can also add other investment related expenses. We can give it a name and a cost and complete it through the entire life cycle. Now we have set up our run, but we actually need to define it's details. So we select EEM run details and remember, we were going to switch from a constant volume system to a variable volume system, so here we're going to select packaged VAV with electric reheat. We're going to make sure that our fan settings are set as we specified.

 In this case, we're simply changing options and we're not changing efficiencies, though it's likely that you would have to re-select the efficiency. We can return to the navigator and click finish. Finally, in order to complete our life cycle cost, we have to specify the first costs and annual maintenance costs of the additional run. 

So, let's say that the VAV system costs an extra 30,000 dollars. And the annual maintenance cost was 6,000 instead of 5,000 because we assume that there's additional control related maintenance. Here we can click finish, and then we can click stimulate building performance. Here it will ask us which runs we want to stimulate. We want them all and we'll click stimulate, save the file, and here the file will load through this brief process that takes about a minute.
