What software should I use?

The selection of modeling software should be based on the specific goals and required outputs of the energy study. Different tools are better suited for different tasks.

Evaluate project needs

Step 1: Identify the Key Metrics Required

Each project requires specific data outputs, such as energy consumption, peak demand, or life-cycle cost analysis (LCCA). Different software tools are designed to produce specific types of data.

Step 2: Evaluate Software Capabilities

Each energy modeling tool has strengths and limitations in terms of modeling complexity, user-friendliness, and output specificity. The following graphic shows many features to consider when selecting a BEM software.

Step 3: Consider the Project's Scale

For larger projects, software that supports whole-building simulations and detailed load calculations is essential. Smaller projects may benefit from simpler tools that focus on specific systems.

Step 4: Consider the Design Questions to be Evaluated

Some tools can model system types better than others.
