This Trane TRACE 700 energy modeling training starts from scratch, we're talking the very beginning of a project. Follow us as we go through weather information. Then we walk you through the creation of TRACE 700 templates, the most important part of a LEED energy model.
First thing we’re going to do is open up Trane TRACE 700, and we’re going to create a new project and we’re going to give this a really original name of “LEED Office.” And so that takes us to the TRACE screen, and the first thing we’re going to do is give the project a name. We’re actually going to call this “Proposed,” in other words this is the building that we intend to build. We’ll select the weather information. Later we’re going to have to do this more in depth, but right now we’re just going to select Chicago. We don’t’ have to worry about the overrides right now unless of course they were specified with the design.
So the next stage in the building is actually the most important part of a design model, it’s the most important part especially for a lead model, is templates. To launch templates we go to the template button or we can double click, and we’ll just double click and open up templates. A lot of people will want to dive in. Before you do this, you should actually look over your building and make a list of the space types. It sounds redundant but it will save you a lot of time, and you’ll see when we go over this. The goal with templates is to have as many templates as needed and no more. So, many people start from the internal load template, but that’s actually the one with probably the most diversity. We want to start with the template that’s the most basic, which is typically the thermostat or the construction template. We’ll start with construction. And so, we can edit the default, but what we can do here is create a new one.
In this case since we know there’s only one construction type, we’re going to edit the default. It’s going to ask us if we wish to rename it, and yes. We’re going to call this “General Building,” since this particular construction type applies to all of the spaces. So, we’ll just go through our little document here and we’ll select the roof, and that’s four inch lightweight concrete and that’s already specified, and we have to get the U-value. This being in Chicago, it’s pretty well insulated. And one thing we want to point out is that the construction type itself is important. Many people think that the U-factor is good enough. You at least want to get something similar in the construction type because Trane TRACE takes into account the mass of the building, among several other parameters.
The next thing we want to select just going down the line is the wall. And that was four inch lightweight essentially block. And we know that it’s highly insulated so we’ll select the one with insulation and we’re going to override this. Then we have partitions. And we’ll just select the one inch wood frame partition. Basically, with partitions it’s really only the U-factor that matters because they’re inside the building and Trane TRACE doesn’t consider their mass in the same way as it does for a wall. So even though we’re going to have glass partitions in the building, we can call it anything here and we just want to get the U-value right. Then we have our standard doors which is already selected, and we just have to override the U-value. We do have some glass doors. We’re going to address that in a minute. For now we’re just talking about the opaque? doors. So we have no skylights so we don’t have to enter anything there, and we just want to enter the window which was double-coated, and we have a U-value of .25 and we have a shading coefficient of .36. One thing you want to remember is to get the height for the wall and the floor-to-floor, and that’s 12 and we have a 3 foot plenum. So effectively right now, we’re done. The one thing that we have not modeled are the glass doors. The glass doors are only present on the vestibules. Copy this template and we’ll call this “Vestibules.”...
Energy-Models.com is a site for energy modelers, building simulators, architects, and engineers who want learn the basics, to advanced concepts of energy modeling. We've got online training courses and tutorials for eQUEST, Trane TRACE 700, OpenStudio, and LEED for energy modeling. All our energy modeling courses are video based. What better way to learn energy modeling software than screen-casts of exactly how things are done?
