What are building energy modeling services?

Building energy modeling uses computer simulation to estimate how envelope, orientation, schedules, occupancy, lighting, plug loads, HVAC systems, controls, ventilation, service water heating, and other inputs affect predicted energy use and cost. Models can compare a proposed design with a baseline, test alternatives, support code-compliance paths, and contribute to sustainability submissions.

Predicted performance depends on assumptions and available design information. Energy modeling is a decision and compliance tool, not a guarantee of actual utility consumption; final outcomes also depend on construction, controls, commissioning, operations, weather, and occupancy.

Use the model to compare real design options.

The scope can begin at concept design and remain current through documentation, value engineering, and final submission inputs.

Concept energy studies

Compare massing, orientation, glazing, shading, envelope, lighting, system, and schedule assumptions early enough to influence design.

Whole-building simulation

Develop proposed and baseline models with traceable geometry, schedules, loads, envelope, HVAC, controls, and utility assumptions.

HVAC option analysis

Compare agreed system types, efficiencies, zoning, ventilation, heat recovery, controls, and plant strategies within the model limits.

Envelope analysis

Test assemblies, insulation, glazing, solar gains, infiltration assumptions, shading, and thermal-performance alternatives.

Code and rating support

Prepare modeling inputs and documentation for applicable energy-code, LEED, or client performance workflows.

Design-change tracking

Update models for approved design changes, value engineering, equipment selections, and final construction-document information.

From multifamily to high-rise and mission-critical.

The delivery framework adapts to each sector’s information, coordination, documentation, and approval requirements.

Multifamily residential

Apartments, condominiums, multifamily, and residential developments.

High-rise & commercial

Towers, offices, hospitality, retail, and mixed-use buildings.

Data centers

White space, grey space, power, cooling, redundancy, and handover.

Industrial

Manufacturing, utilities, equipment interfaces, access, and installation.

Healthcare & institutional

Hospitals, education, civic, and coordination-intensive facilities.

Infrastructure

Site, civil interfaces, utilities, logistics, and model-based sequencing.

Keep assumptions visible as the design changes.

A useful energy model records what is known, what is assumed, what changed, and which decision each run is intended to support.

  1. Set the modeling basis

    Confirm objectives, applicable standard or program, climate data, design stage, software, review team, and required outputs.

  2. Build the baseline

    Assemble geometry, envelope, schedules, loads, systems, controls, and documented assumptions from current project information.

  3. Test alternatives

    Run agreed options, compare energy and cost outcomes, check reasonableness, and identify sensitive assumptions.

  4. Update and document

    Reflect approved changes, finalize inputs, prepare reports or submission data, and preserve a transparent assumptions record.

Before you engage the delivery team.

Clear answers on scope, responsibility, standards, and project setup.

When should energy modeling start?

Early modeling provides the most design value because massing, envelope, glazing, shading, and system choices are still flexible. The model can then be updated as the project develops.

Can an energy model predict actual utility bills?

It estimates performance using documented assumptions and inputs. Actual energy use can differ because of weather, occupancy, operations, controls, construction quality, equipment performance, and other factors.

Can BIM geometry support an energy model?

Yes, but the analysis model typically requires zoning, simplification, cleanup, construction properties, schedules, loads, systems, and assumptions that are not contained in geometry alone.

Can energy modeling support Title 24 or LEED?

Yes, when the model follows the applicable program, software, baseline, documentation, and submission requirements. BIM Bots has dedicated pages for California Title 24 and LEED energy modeling support.

Which sectors can use energy modeling?

Potential projects include multifamily, high-rise, commercial, hospitality, data-center, industrial, healthcare, education, institutional, and other conditioned buildings.
