Building Performance
Energy Performance Starts With the Building as a System
Building performance is influenced by more than a single mechanical system or equipment selection.
Geometry, orientation, envelope characteristics, occupancy, internal loads, ventilation, HVAC systems and operating assumptions can all influence how a building performs.
Digital analysis provides a structured method for reviewing those relationships during design and project development.

Analysis Workflow
From Project Information to Performance Insight
01
Define Objective
Establish the performance question or design comparison.
02
Review Inputs
Review BIM, architectural, envelope and system information.
03
Prepare Model
Structure required geometry, zones and project data.
04
Apply Assumptions

Performance Inputs
An Energy Result Is Only as Useful as Its Inputs
Building-performance analysis depends on the project information, assumptions and operating conditions used in the model.
A professional workflow should keep significant assumptions visible rather than presenting an analysis result without context.

Analysis Quality
Analysis Complete Does Not Automatically Mean Inputs Were Correct
A performance tool can successfully complete a calculation even when an input, schedule or assumption does not reflect the intended project condition.
Input review and assumption visibility are therefore important parts of a controlled analysis workflow.
Geometry Review
Confirm relevant building geometry is represented.
Envelope Review
Check major envelope inputs and assumptions.
Occupancy Review
Confirm usage assumptions align with project intent.
System Input Review
Review relevant mechanical-system information.
Assumption Documentation
Keep significant project assumptions visible.

Frequently Asked Questions
Energy & Sustainability FAQs
What is building energy modeling?
Building energy modeling uses digital building information and defined assumptions to study how geometry, envelope, occupancy, operating conditions and building systems can influence energy performance.
Can BIM models be used for energy analysis?
BIM information can provide useful geometry and project data, but the model should be reviewed and prepared according to the requirements of the intended analysis workflow.
Can alternative design options be compared?
Depending on the project scope, selected building-envelope, HVAC, orientation or operating scenarios may be structured for comparative analysis.
Why are assumptions important?
Performance results depend on inputs such as occupancy, operating schedules, envelope characteristics and system information. Significant assumptions should therefore remain visible during interpretation.
Can you support existing-building projects?
Existing BIM, drawings, Scan-to-BIM models and available building information can support performance-oriented workflows where the required data is available.
What information is useful to begin?
Typical information can include architectural geometry, building location, envelope data, space usage, occupancy assumptions, mechanical-system information, operating schedules and the specific performance question being studied.
