The VE provides functionality to include or exclude diversity factors for each sizing step and saves a designer’s preferences for future projects. Fig 2: HVAC System loads calculation interface in IESVE . For example, a designer can turn off diversity factors for zone/room loads calculations. These results can help the designer analyze the impact and contribution of envelope and internal gains on the non-coincident cooling/heating loads. Diversity factors .
Diversity factor This value is valid for all types of gains and will be applied as a multiplicative factor in simulation runs. It doesn’t effect any design simulations like CIBSE loads or Apache Loads.
VE 2017 ApacheHVAC User Guide part F: Loads Analysis and Reporting Tools 9 Figure 2-4: Internal gains dialog, accessed from the Building Template Manager, with the Diversity factor set to 0.8 for the selected lighting gain This option is available for both heating and cooling loads calculations. By default, diversity factors are excluded, Only by looking at buildings and cities as the integrated environments that they are – instead of parts of the problem in isolation – can we ensure everyone involved in the conception, design or management of a building gets to leave our world in a much better state than we inherited it.
By default, diversity factors are excluded for Room & Zone Loads and included for System Loads. Figure 2 – 5 : ASHRAE Room & Zone Loads dialog with the Diversity Factors not applied to internal gains Design Day Profiles . In ApachePro, two new day types have been added to allow for the definition of specific heating and cooling design day …

Diversity factor – Wikipedia, Diversity factor – Wikipedia, If you tick this box, and Include internal gains? is also ticked, the diversity factors assigned to the gains will be appiied for the heating load analysis. Saturate gain profiles? If you select ‘Yes’, and Include internal gains? is ticked, gains wlll be saturated, meaning that when their modulating profiles are evaluated, all values …
