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.

OpenBuildings Energy Simulator 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:
