Why Use Energy Audit Software? OptiMiser Commercial OptiMiser Commercial is a professional audit software aiding in data collection, measure analysis, and reporting.

OpenStudio OpenStudio operates across Windows, Mac, and Linux platforms and is a collection of software tools that uses EnergyPlus and Radiance to support whole building modeling and advanced daylight analysis. Subscribe to Email Updates.

Also, it comes with a variety of building project templates to further modify such as hospital, small hotel, secondary school, supermarket, warehouse, office, etc. As you launch the software, you will see various modules at the left side of the interface.

These modules include Site add weather file and date , Schedules , Constructions create construction sets for surfaces , Loads create load definition for load objects , Space Types define loads, schedule, and construction sets , Geometry , Thermal Zones edit thermostat, humidistat, zone equipment, etc. For each module, you get different tabs to prepare respective data set. To add items to your model, there are tabs named My Model see items included in your model , Library , and Edit edit settings for components at the right side of the interface.

The Library contains several preloaded components to use in your models. You can drag and drop a file from Library to the main working window to build an energy model. The library is well categorized depending upon the item type. After creating an energy model, you can export it in the format of OpenStudio project.

Use Run Simulation feature to compile your energy modeling project. Prior to that, you can configure simulation settings which include date range, sizing parameters, radiance parameters, simulation control, convergence limit, heat balance algorithm, shadow calculation, zone air contaminant balance, etc.

Simergy is a free building energy modeling software for Windows. The activation key is sent through email which is used while registering an account on its official website. Now, you can start with designing a building and perform energy analysis for it. To have a better understanding of how to create energy models, have a look at its video tutorials. Using Active Project Model tree, you can add components to design a building in 3D view or plane view like building stories, spatial zones thermal zones, floor plena, etc.

A Level 2 audit provides enough data to justify the implementation of a project without the need for additional data collection and analysis. An ASHRAE Level 2 audit is for those businesses wishing to improve energy efficiency, hone in on how the whole building is functioning, and identify the projects that will provide the greatest energy reduction at the best return on investment ROI.

A Level 3 audit builds on the findings and recommendations of a Level 2 audit by offering a more in-depth engineering analysis of potential changes. Detailed gathering of data in the field is conducted, and that data is analyzed more intensely for areas of improvement and potential costs. A Level 3 report offers a better baseline, allowing the business to compare energy and operating savings both pre- and post-implementation.

Level 3 audits are for those businesses that have already completed a Level 2 audit, has identified capital cost projects that it wants to undertake, but needs more data before making that size of an investment.

No matter what level of ASHRAE energy audit your business wants to complete, you need a tool that helps you gather the necessary data quickly and accurately.
