Boundary

Represents the boundary of a Surface

By default (i.e., if no boundary is assigned to a Surface), the boundary will be assumed to be outside.

Note: This object cannot be declared by itself in a SIMPLE model. It is always embedded on a Surface

Examples

A Space boundary (in .json)

{
    "type": "Space",
    "space": "Some Room"    
}

A Ground boundary (in .json)

{
    "type": "Ground"
}

Supported Variants

Outdoor

Leads Outdoors. This is also the default (i.e., when no Boundary is set)

Full Specification

{
	type: "Outdoor"
}

Ground

The Surface is in contact with the Ground

Full Specification

{
	type: "Ground"
}

Space

The Surface leads to another space whose temperature and other properties are part of the simulation

Border conditions:

• Solar Radiation: As calculated by the Solar module
• Net Shortwave (IR) Radiation: Zero, for now at least (this is a good assumption if the surfaces inside the Space are at similar temperatures)
• Convection Coefficient: Indoor
• Wind: No

Full Specification

Boundary {
	type : "Space", // this should not change
	space : string
}

AmbientTemperature

The surface leads to an environment with no wind or sun, and with a fixed mean-radiant and dry bulb temperature

This object is useful for defining surfaces that lead to spaces that we one is not interested in modelling; for example, a wall that separates an apartment's room with the hall of the building. In that case, we don't need to simulate the temperature of the hall... but we can assume a certain temperature.

Border conditions:

• Solar Radiation: None
• Net Shortwave (IR) Radiation: The set temperature
• Convection Coefficient: Indoor
• Wind: No

Full Specification

Boundary {
	type : "AmbientTemperature", // this should not change
	temperature : number
}

Adiabatic

The temperature of the other side of the wall will be the same as the one measured at the interior of the space

Full Specification

{
	type: "Adiabatic"
