Building Data LINEAR Building

Building

Examples...: Opens a list with different building ventilation layouts. When you select an entry, the fields Building Type, Ventilation Zone, Building Unit and the status of the option Consider apartments with the same name and number as one apartment are preset to match the selection. After making a selection, check all settings for compatibility with the standards used.

Type of Building: Drop-down list for selecting the building type. This information has an impact on various calculations, e.g. on the calculation of the heat load or domestic ventilation. If a non-residential building is selected, the term Area is used in the building structure, in drop-down entries in the building data for selecting building units and ventilation zones and in the printout instead of the term Apartment. This term can be adjusted in the Configuration in the Project Settings area.
Note: For the Dutch heat load, the selection of the building type also determines the calculation method: One-family, two-family and multi-family houses are calculated in accordance with ISSO 51. Offices/administration buildings and other buildings are calculated in accordance with ISSO 53. When using the Dutch standard for the heat load calculation, selecting Mixed Building enables you to select the applicable building type and thus the calculation method for each building unit.

Ventilation Zone: Drop-down list for selecting the structural level on which ventilation zones are defined in the project. You can choose between project, building part, storey and apartment / area. For calculation according to ISSO, the ventilation zone must be on the same level as the building unit.

Building Unit: Drop-down list for selecting the structural level on which building units are defined in the project. You can choose between project, building part, storey and apartment / area. To perform a heat load calculation in accordance with the Dutch standard, the building unit must be on the same level as the ventilation zone.

Note:
  • The settings for the ventilation zone and building unit are required for the heat load calculations in accordance with EN 12831-1 and its national supplements.
  • For DIN EN 12831 (2008), defining a building unit is required in order to correctly identify adjacent components of a building unit as being adjacent to a differently heated or heated area.
  • Settings for the building unit are not relevant for the heat load calculation in accordance with DS 418.

In the calculation in accordance with DIN EN 12831 (2008), building components that are adjacent to heated rooms in another building unit have the status adjoining an apartment with little or no heating (uw). Components adjoining to a heated room of the same building unit are given the status adjoining to a heated room (i,j).

Consider apartments with the same name and number as one apartment: Prerequisite for this function is that on the project level in the building data BU and VZ are both set to Apartment. The function is activated by default.

Enabled: Apartments that are on different storeys or building parts but have the same number and name are considered as one apartment in the heat load calculation. At the apartment level, all rooms belonging to this apartment are displayed, regardless of the current storey. In order to connect an apartment to another one after it has been detected, the name and number should be manually adjusted in the apartment that is being added. The added apartment receives the BU and VZ settings of the existing apartment. The BU and VZ settings of connected apartments are synchronized in both directions.

Disabled: Apartments that have the same number and name are considered to be separate apartments and are charged separately.

Geometry

Building Length, Building Width: These dimensions must be entered manually. If these fields are filled, the values can be used to calculate the surface area.

Building Area: During building detection, the area of the building is determined and entered in the field. With manual entry, you can enter a freely selected value. By clicking you can calculate the area using the length and width of the building.

Building Height: The height of the building is calculated on the basis of the storeys defined in the project. Alternatively, you can also enter a freely selected value. Click to return to the calculated value.

Building Volume: The building volume is calculated using the dimensions specified. Alternatively, you can enter a freely selected value. Click to return to the calculated value.

Ground-Adjoining Floor of All Heated Rooms

Length, Width If the CAD program transfers length and width for surfaces in contact with the ground, the corresponding internal wall dimension is entered at this point after the building detection has been carried out. If no values are transferred, if custom values should be used or if the building is created manually, you can enter user-defined values. These values are not used in any calculation and are purely for information purposes.

Area: The area of the ground-adjoining floor in heated rooms calculated according to the standard. This value is calculated using the dimensions of the enveloping surfaces adjacent to the ground (usually floors). Alternatively, you can enter a freely selected value. Click to overwrite a manual entry and enter the value calculated from the enveloping surfaces. If there are no enveloping surfaces adjacent to the ground, clicking on removes a manually entered value.

Outline: The outline of the ground-adjoining floor in heated rooms calculated according to the standard. This value is calculated using the dimensions of the enveloping surfaces adjacent to the ground (usually floors). Alternatively, you can enter a freely selected value. Click to overwrite a manual entry and enter the value calculated from the enveloping surfaces. If there are no enveloping surfaces adjacent to the ground, clicking on removes a manually entered value.

Note: When you open a saved project, the values for Area and Perimeter are recalculated from the floors or enveloping surfaces in contact with the ground that are currently present in the project. If you have adjusted these values manually, the calculation is not updated from enveloping surfaces in contact with the ground.

Groundwater Depth: Enter the ground water depth for the project location. This will be used to calculate the heat losses at areas in contact with the ground.

Depth of Floor Slab: Specify the depth of the floor slab. The depth of the floor slab corresponds to the upper edge of the lowest floor in the building.
