Heat Load Calculation by using Trace 700 Software

Create a zone plan for Trace 700 heat load calculation by building a detailed space sheet from architecture drawings, determining orientation, exposure, walls, windows, roof, partitions, and internal loads.

Learn how to add weather data in trace 700 per Ashrae 2021 for Bengaluru, India, including override steps and entering dry bulb, wet bulb, clearness number, ground reflectance, and CO2.

Create a space template in Trace 700 using internal load templates for people, lighting, miscellaneous equipment, and schedules; enter sensible and latent heat, density, and lighting load values.

Configure airflow and thermostat templates in Trace 700, covering ventilation and infiltration loads, cfm per square foot, neutral construction, and thermostat set points including humidity and drift points.

Learn construction templates in Trace 700 to compute u-factors for slabs, roofs, walls, and partitions using ASHRAE handbook values, including glass types, skylights, and plenum dimensions for heat transfer.

The room template acts as a super template, a composite of other full templates. When you apply it to a room, its constituent full templates are automatically applied.

Create rooms in Trace 700 using the single sheet tab, populate room names and dimensions, then add roof and wall details, airflow, and internal loads, finally apply.

Enter room details in the create rooms tab, including room name and total area or length and width, then apply to save classroom, office, and lobby entries.

Create and assign roof and skylight details to each room in a Trace 700 project, including roof type, pitch, direction, and equal floor conditions, to accurately compute loads.

Learn how to enter exposure walls and openings in Trace 700, compute net wall areas by subtracting window areas, and configure wall direction, height, tilt, and ground reflectance.

Learn to configure internal loads in Trace 700 for classrooms, including occupant density, per-person area, and miscellaneous and equipment loads using templates.

Assign ventilation, infiltration, and airflow loads to each room, using ASHRAE 62.1-2004 values for CFM per person and per square foot, and select ceiling or floor CLG and HG options.

Enter and configure partition walls and floors in Trace 700, calculating exposed slab perimeters and loss coefficients for classrooms, canteen, and lobby to model heat loads accurately.

Learn to create airside systems in trace 700 by using the selection tab to pick system category and type, such as variable-volume with reheat, sizing room airflow, coils, and fans.

Explore create system options in trace 700, including evaporative cooling, economizers, and stage one and stage two air-to-air energy recovery, with heat recovery wheels transferring energy to outdoor air.

Create a dedicated outdoor air system using Trace 700, configure fixed set point ventilation, choose deck or system-level location, or select none to let the main coil handle ventilation.

Configure design temperature and humidity in the screen, applying min/max values and dehumidification options to guide airflow and set cooling and heating supply temperatures 55–60 f and 120–140 f.

Learn to configure the system fan override in Trace 700 by selecting a fan cycling schedule (occupancy, heating, or cooling) and setting static pressure for the air handling unit.

Create coil overrides in Trace 700 to set 100% of calculated design cooling and heating capacity, including preheat and reheat coils, and apply the internal heat gain variance factor.

Explore how a preheat coil warms outdoor air, how the evaporator coil removes heat, and how a VAV terminal box modulates damper-driven airflow for zone comfort.

Learn to assign rooms to systems in Trace 700 by dragging unassigned rooms into system zones, forming a tree structure that groups rooms into zones and systems for accurate sizing.

Learn how to calculate and view results in Trace 700 by adjusting load parameters, selecting cooling months, and applying esri tables for cooling load calculation, heat gain, and heat balance.

Learn to export heat load calculations from Trace 700 by selecting report components, choosing pdf, Excel, or Word formats, and saving design cooling load and load airflow summaries for reports.
