HVAC Load Calculation Using HAP 6.2 Software

Explore how HAP 6.2, Carrier early analysis program, performs hvac load calculations and energy analysis to determine cooling and heating loads, system capacity, and energy cost aligned with ASHRAE standards.

Compare the old HAP versions with HAP 6.2 to highlight differences in calculation methods, accuracy, analysis type, interface, BIM integration, energy analysis, and weather data.

Learn to add weather data in HAP 6.2 by selecting a weather station from the ASHRAE database, configuring design parameters for Hyderabad, and setting cooling and heating design conditions.

Enter building properties in HAP 6.2, including general information, level to level height from dwg drawings, glazing and window frame details, and ceiling or raised floor options.

Import PDF or CAD floor plans under the floor plan images tab, then set north orientation and scale for each floor to ensure accurate hvac load calculations in HAP.

Create ground, first, second, and roof levels for the floor plans, name each level, set occupiable or roof type, and align floors with a shared reference marker, then lock positions.

Learn to draw and trace external, interior, glass, and partition walls in Revit, assign wall types, name spaces, and verify ceiling and level heights for accurate 3d models.

Explore the 3D view to verify building geometry and window placement, then use model checking to detect missing constructions, assignments, and undefined systems before load calculations.

Understand space types as predefined room templates in HAP, containing occupancy, lighting, equipment, ventilation, and schedules to save modeling time and ensure ASHRAE-based ventilation.

Define wall layers in HAP 6.2 by configuring an exterior wall with absorptivity settings, detailing bricks, air gap, plywood, metal stud, and gypsum board, then compute R and U values.

Define roof layers in hap 6.2 by creating a default roof, selecting a single 12-inch masonry concrete layer, and removing extras to yield the 1.66 R and 0.55 U values.

define ceiling layers in hap 6.2 by creating a default ceiling, naming the assembly, setting outside absorptivity and light color, and applying acoustic tiles to compute R-value and U-value.

Define floor layers by selecting slab on grade and setting absorptivity (light 45% or medium 67.5%), then specify masonry concrete 12 inch and U value 0.553 with ASHRAE 0.92 resistance.

Learn to add window data in HAP 6.2, using simple or detail input to set U value, SHGC, VT, and glazing details, frame type, and gap types for daylighting modeling.

Add door data in HAP 6.2 by specifying door name, type (glass or opaque with light), and adjusting glass U value (0.83) and SHGC for accurate performance.

Define the space model in the general tab for hvac load calculations, including naming the space model, selecting the associated educational building, and adding notes for project details.

Define and create spaces in HAP 6.2 to set up accurate HVAC load calculations and improve model organization.

Implement thermal zoning by dividing the building into zones served by one thermostat and one airflow control, assign spaces to zones, and designate unconditioned areas across floors.

Select exterior and interior wall, roof, ceiling, and floor layers from the project library in HAP 6.2, and create new assemblies by entering layer details when needed.

Select and configure an air system in HAP 6.2 for an educational building, choosing AHU with chilled water, a VAV system, space model, and notes per ASHRAE standards.

Connect zone components to the ahu or package unit, assign zones to the system, and see how zone data drive airflow, cooling loads, and system capacity in hap 6.2.

Size hvac systems with the HAP 6.2 sizing data: compute AHU airflow, coil capacity, and system size using computer generated calculations; learn when to use system versus zone sizing.

Define a default plant and educational building alternative, then activate the view design report for system inputs; resolve wall assemblies, review coil loads, and note zone sizing for duct design.
