eQUEST is a sophisticated, yet easy-to-use building energy use analysis tool which provides professional-level results with an affordable level of effort. This freeware tool was designed to allow you to perform detailed analysis of today’s state-of-the-art building design technologies using today’s most sophisticated building energy use simulation techniques, but without requiring extensive experience in the “art” of building performance modelling. This is accomplished by combining a building creation wizard, an energy efficiency measure (EEM) wizard and a graphical results display module with an enhanced DOE-2-derived (software) building energy use simulation programme.
eQUEST features a building creation “wizard” that walks you through the process of creating an effective building energy model. This involves following a series of steps that describe the features of the design that would impact energy use, such as:
The eQUEST building creation wizard first requests the most general information about the building design, and then delves into progressively deeper detail. In all, the building description process comprises 23 data-entry steps – each represented by a “wizard” screen. At each step of describing your building design, the wizard provides easy-to-understand choices of component and system options. It also offers advice in the form of “intelligent defaults” for each choice. In addition, eQUEST automatically skips steps that do not apply to the chosen design.
Although the building description process can get quite detailed, it isn’t necessary to complete every single step in the wizard. If chosen, the user can “bail out” of the description process once he/she is satisfied with the level of detail. At that point, the wizard fills in any missing information using the eQUEST “intelligent default” process.
After compiling a building description, eQUEST produces a detailed simulation of the building, as well as an estimate of how much energy it would use. Although these results are generated quickly, they are quite accurate because this software utilises the full capabilities of DOE-2 (the latest version of a well-respected and popular building energy simulation program developed over the last 20 years by the U.S. DOE). Within eQUEST, DOE-2 performs an hourly simulation of your building design for a one-year period. It calculates heating or cooling loads for each hour of the year, based on the factors such as:
DOE-2 also simulates the performance of:
During the simulation, DOE-2 also tabulates your building’s projected energy use for various end uses, such as:
eQUEST offers several graphical formats for viewing simulation results. For instance, the user can display graphs of estimated overall building energy on an annual or monthly basis. The user can also compare the performance of alternative building designs. In addition, eQUEST allows you to perform multiple simulations and view the alternative results in side-by-side graphics. It offers:
The current version of eQUEST provides even more comprehensive analysis capability. It allows the advanced user to input additional building details to analyse complex buildings. A three-dimensional view of

Imagine a building energy simulation tool comprehensive enough to be useful to ALL design team members, yet so intuitive ANY design team member could use it, in ANY or ALL design phases, including schematic design. eQUEST is aptly named because it provides something that you have been looking for, but have been unable to find: a sophisticated, yet easy-to-use building energy analysis tool. With eQUEST, you will be able to provide professional-level results with an affordable level of effort.
The eQUEST software tool is free of charge.
The tool runs on Windows 8/7/Vista/XP, and previous versions of Windows dating back to Win98. eQUEST does not run on Mac OSX, iOS, Android, or other operating systems.
