Internal heat gains people

Persons

CL BS
The capacity for people is the maximum capacity of the heat that is produced, expressed in W/m², W or total number of people. For persons, the capacity is calculated based on the specified CLO and MET values.

If W/m² is entered, heart-to-heart size, excluding wall thicknesses are used to determine the square meters.

The power specified here is the total power. In this the tangible power and the latent power are added together.

CLO-value summer

Standaard 0,7 CL BS
Dit is de thermische isolatie van het lichaam ten gevolge van gedragen kleding, ook wel kledingisolatie genoemd. 1 clo = 0,155 m².K/W. (ISSO 19 2.1.1.). Omdat deze instelling voor koellast gebruikt wordt, geven we personen met weinig kleding op, zodat de warmteproductie hoog uitvalt. De zomerperiode loopt van 27 april tot en met 27 september.

Let op: Eigen waarde kan worden ingevuld voor gebouwsimulatie, wanneer deze wordt ingevuld voor koellast zal gerekend worden met de dichtsbijzijnde hogere stanaard waarde.

CLO-value winter

Standard 0,9 CL BS
This is the thermal insulation of the body as a result of worn clothing, also known as clothing insulation. 1 CLO = 0.155 m².K / W. (ISSO 19 2.1.1.) Because this setting is used for building simulation in winter, we give up people with a lot of clothing, so that the heat production is low and more heating is required. If a chair is used, the insulation resulting from the chair must be added to this (0.15 clo for, for example, an office chair). The winter period runs from 28 September to 26 April.

Note: Own value can be entered for building simulation, if it is entered for cooling load, the closest higher standard value will be used.

Activity MET-value

Standard RGD (126 W, M= 1,20) CL BS
These are for defined activities that include a wattage per person and a metabolism (M).

1 MET = 58.2 W / m². For an adult, 1.8 m² should be charged per person. (ISSO 19 2.1.1.)

Note: Own value can be entered for building simulation, if this is entered for cooling load, the closest higher standard value will be used.
