    Calculations - Occupancy and heat gains

      Product(s): Hevacomp Mechanical Designer
      Version(s): V8i (N/A)
      Environment: N/A
      Area: N/A
      Subarea: N/A

    Overview

    The number of occupants and activity with which they are employed will have an effect on any heat gains in the space being considered.

    Method

    The Design Database program provides a facility for providing the number of occupants and the activity they are involved in.

    Available activity types

         Seated at rest    

        Office work   

        Walking   

        Light work   

        Medium work   

        Heavy work   

     Mapped to the CIBSE guide

    Available types

    Activity types in CIBSE guide A

    Seated at rest

    Seated, inactive, theatre or cinema

    Office work

    Seated light work, restaurant, seated moderate work, office

    Walking

    Standing light work, walking, department store of bank

    Light work

    Light bench work, factory

    Medium work

    Medium bench work, factory, moderate dancing, dance hall

    Heavy work

    Heavy work, factory

    • Data is based upon CIBSE Guide A, Section 6, for heat emissions from an adult male body.

    • Data is supplied for a number of fixed points (figures shown in black)

    • If the room temperature exceeds 26°C then the figures for 26°C are used.

    • If the room temperature falls between the fixed data points, then the values are interpolated (example interpolation shown in yellow)

    The interpolation function uses the following methods:
