Structure of adjacentTo:
Created by: Maryamzk
I have a doubt about structure of "adjacentTo" association, which I think is needed to be discussed here.
The recent structure of adjacent association is not able to identify the thermal characteristics of the adjacent surface but the whole adjacent zone. Therefore, if some thermal parameter of the adjacent surface should be specified, the defined adjacent association should be modified. Below you can find some examples about the parameter of adjacent zone in ISO 13790 and DIN 15899 which are required for heating demand of the thermal zone. I have explained where re-structuring of the adjacent association might be required, but the energy-expert persons can approve it.
In ISO 13790:
- Time-averaged heat flux from all solar sources in the unconditioned adjacent zone. This heat flux in unconditioned is calculated like heat flux in thermal zone for all surfaces (see equations bellow), therefore the adjacent surface should not necessarily be identified. In other words, according to the current definition of ThermalZone class and adjacentTo association, when solar sources of thermal zone are identified, the solar sources for unconditioned adjacent zone are also identified. The only missing point is to recognize an adjacent zone is conditioned or not, right?
In DIN 15899: -Solar radiation passing through the sunspace into the adjacent building. For calculating this we need to know the area of the adjacent surface (see the equations bellow), we need re-structuring in adjacent (DIN 18599-section 6.4)
heat flow into the unheated or uncooled sunspace:
is the total solar radiation passing through the sunspace into the adjacent building zone, calculated using equation (below) for all transparent elements of the partition separating the building zone considered and the unheated sunspace;
