EnergyGauge Summit
vertical specialistResidential energy modeling and HVAC load calculation software used for code, efficiency, and sizing analysis.
Hourly load profile export that ties room and zone assumptions to peak load analysis outputs.
EnergyGauge Summit fits engineers who need repeatable load calculations across many rooms because it organizes inputs into a project model that ties envelope, internal gains, and operational schedules to each zone. The export layer supports load profile export so HVAC sizing teams can move from peak load analysis to equipment selection outputs. The calculator is built around consistent design conditions so scenario comparisons stay aligned when assumptions change between iterations.
A tradeoff is that complex workflows often require careful assumption hygiene because small mismatches in infiltration, ventilation, or schedule definitions can ripple across hourly profiles and total sensible and latent loads. EnergyGauge Summit works best when a project team already has room inventory and envelope data ready, such as during schematic-to-design development iterations where zone totals must reconcile quickly.
- +Room-level inputs produce consistent zone load summaries
- +Hourly load profile export supports downstream sizing workflows
- +Envelope parameter coverage supports U-value and R-value driven models
- +Scenario iteration reduces rework during design development reviews
- –Assumption mismatches can distort infiltration and ventilation impacts
- –Advanced modeling depends on disciplined schedule and internal gain setup
- –Grid-intensive projects can feel slower when many zones are recalculated
- –Some integration paths require external conversion of building geometry data

IES VE
enterpriseBuilding performance modeling software that includes heating and cooling load calculations for HVAC design.
IES VE’s Visual Environment workflow keeps thermal construction, schedules, and HVAC assumptions linked for repeatable load recalculation.
IES VE supports heat loss and heat gain calculations at the zone and room level, then aggregates results into zone load summaries suitable for peak load analysis. The software uses weather data files and hour-by-hour conditions to drive heat gain calculations and ventilation and infiltration loads. VE’s strength is repeatable modeling of envelopes, internal gains, and HVAC assumptions across design iterations.
A tradeoff is that VE modeling requires consistent construction definitions and HVAC input structure or results can drift across scenarios. VE fits teams that already manage design geometry and schedules in a BIM-centric workflow and want engineering control over loads before equipment selection.
- +Room-by-room heat balance that aggregates into zone load summaries
- +Hourly weather-driven calculations for peak load analysis
- +Repeatable assumption control across design iterations
- +BIM-centric geometry and load model exchange paths
- –Setup needs disciplined input structure to prevent scenario drift

A tradeoff appears in how tightly the process depends on accurate building model data, especially for envelope assemblies, window parameters, and air change assumptions. Teams that maintain construction and opening attributes in a consistent way get faster rework cycles when design geometry changes. Teams with frequently shifting ad hoc assumptions often spend more time correcting input parameters than interpreting results.
- +Room and zone load breakdown tied to envelope and openings parameters
- +Heating and cooling cases share one project workflow for scenario iteration
- +Reports support structured review of load components and totals
- +Structured outputs support downstream HVAC equipment sizing decisions
