Possible hint

For certain coatings there are combination specifications for the basis glass that should be used. On pasting such a coating an appropriate hint is made:

Only coating (without basis glass) will be pasted

Coating and marked basis glass will be pasted

6.2 Relocate layer

1. Mark layer with the left mouse button or in the window “coat sequence”

2. Drag the marked layer to the requested position.

(Alternative: Arrow keys left/right)

6.3 Delete layer

For the deleting of a layer you mark it by left-clicking (multiple selection with pressed “Ctrl” key) and hit the “Del”.

Alternatively to this you mark the layer by left-clicking and subsequently activate the context menu by right-clicking. Choose “delete layer” for deleting it.

6.4 Change layer thickness

For changing the thickness of a basis glass, a PVB film or a gas, double-click the appropriate layer with the left mouse button.

Above the layer marked like this appears the currently appointed thickness that may be overwritten with the requested value.

Alternatively you can choose a layer by left-clicking and invoke the context menu by right-clicking. By choosing “change thickness” now you can type in a random thickness (explained above).

6.5 Change gas mix

The default setting when pasting an interstice filled with gas is 100% gas with a filler loading of 90%. Air-filled interstices are occupied with 100% air and 100% filler loading by default.

By left-clicking you choose a layer and by right-clicking you invoke the context menu. When choosing “change gas mix” a new window opens up, where you can define a custom gas mix.

Please type in your own gas mix here. It will only be changed here in the component range, not in the material database.

In this example the resulting mix consists of 90% argon, the rest is filled up with air.

Filler loadings over 90% are only possible using the expert editor. The limitation of the filler loading is a recommendation by the producer, since windows with filler loadings over 90% are rarely produced.

6.6 Layer composition

This area displays a detailed description of the coat sequence.

Under “layer composition” the physical properties of the currently chosen layer is displayed.

P.r.n. a hint for the marked layer will be displayed here.

6.7 Improved handling in the editor

9 Declaration of performance and CE

The producer must allocate a declaration of performance according to article 6 of the “BauPVo” for each building product that has to be provided with a CE mark when placing it on the market.

The declaration of performance quotes the performance of a building product related to the essential features of a building product concerted with the underlying harmonized technical specifications.

Basis for the declaration of performance is a technical documentation that has to be made by the producer that contains a description of the elements in conjunction with the required system for valuing and verifying the constancy of performance.

9.1 Preview

Using the tab “declaration of performance” / “CE” you receive a preview for the declaration of performance / CE.

11 Expert editor

The expert editor includes extra functionality in addition to the standard editor:

· Calculation in accordance with EN 410, EN 673 and EN 13363-2

· Random number of layers

· Aired interstices

· Assembly in the space between the panes

· Variable parameters

· Surface material

· Lamellas

11.1Aired interstice

Air spaces that are connected with outside or inside air can be pasted from the master data area. Thereby “air ventilated outside” describes a building component layer with the air intake from outside and the air outtake outwards.

“Air ventilated inside” describes a building component layer with air intake from inside and air outtake inwards (The procedure described in EN 13363-2 are not taking into account a convection caused by wind pressure).

11.1.1 Change ventilation factor

To change the ventilation factor of an interstice, you mark it and choose the point “change ventilation factor” in the context menu (right-click). In the following dialogue you can state the aperture ratios A_in und A_out.

Using the button you get to a helper dialogue that supports you calculating the aperture ratios.

11.1.2 Explanations for the ventilation factor

The aperture ratio is the relation to the cross sectional area

* 100 ≤ 100; 100 [%]

With:

The opening ratio is the relation to the cross sectional area

* 100 ≤ 100; 100 [%]

With:

Cross sectional area

Aperture ratio left

Aperture ratio right

Aperture ratio top

Aperture ratio bottom

Aperture ratio holes

For asymmetric opening distributions from the top to the bottom there has to be made realistic assessments.

Please note

EN 13363-2, attachment B describes this procedure for the “estimating” of convection currents at the calculation. It is believed that A_l, A_r and A_h preferably exist homogeneous about the height H.

11.1.3 Mechanical ventilation

11.2Assembly in the SZR

In the master data area you have different surface materials and slats available. These can be directly dragged to an existing space between the gas.

For pasting in a space between the gas simply drag the material of choice with pressed left mouse button (from master data or insertion point) to the requested interstice until a red rectangular appears.

Then drop the mouse button. Subsequently you will be asked to quote a ventilation factor.

The pasting of the surface material splits the gas-filled compartment in two symmetric bound together gas-filled compartments that can be adjusted afterwards.

At the first indication of the ventilation factor, this one will be undertaken for both gas-filled compartments.

Please note:

When gas-filled compartment thicknesses are changed afterwards, A_s. changes, meaning the ventilation factor can possibly change and eventually has to be adjusted afterwards. Please do not forget that both gas-filled compartments have to be considered separately and the change of the ventilation factor in one gas-filled compartment will not be undertaken for the other ones automatically.

11.3Change boundary condition

In the master data area you find different climatic boundary conditions according to EN 13363-2 and ASHRAE. For new structures there will be standardly preallocated “EN 13363-2 reference”.

The boundary conditions for simulating the thermal behavior can be selected by double-clicking.

The sketch bottom left shows which boundary condition you chose.

Additionally you can define proper boundary conditions.

With the interface below the new boundary conditions will be settled:

11.4Create slat (Slat module)

1. Click on

2. With the following interface the slat data will be determined:

3. Enter fraction of direct radiation:

Generally, a fraction of 85% of direct radiation is used for calculation, according to the specification in EN ISO 52022-3. If other fractions of direct and diffusive irradiation are required, the setting can be edited, deviating from the standard.

4. Selection of the plain material:

5. Defining of the slat geometry and angle

The slat geometry is defined by slat width l, center distance d, slat tilt α and sun height angle h (left sketch).

According to EN ISO 52022-3, direct sun irreadiation into the room is not allowed
(right sketch X).

The geometry parameters l, d, α und h have tob e chosen in a way to prevent direct sun irradiation (middle sketch √ ).

When direct sun irradiation occurs, WINSLT shows a warning. The slat geometry has to be adjusted:

6. Saving the slat with “OK”.

7. The new slat now appears in the tree

11.5Silkscreen

11.5.1 Generate silkscreen glass

When choosing “generate silkscreen glass” silkscreen glasses can be generated by reference to the spectral data of the unprinted and printed surface. By double-clicking on an entry an appropriate dialogue opens up.

11.5.2 Silkscreen glass in VSG

The calculation of a layered structure of screen-printed glass + PVB + base glass is not permitted. To be able to calculate screen-printed glass in laminated safety glass anyway, proceed as follows:

1. Import printing as coating

2. Save VSG with printing as product

3. Save VSG without printing as product

4. Generate screen printing glass for desired degree of printing

5. Calculation for partially printed VSG

12 Import spectral data

Spectral data can be imported in form of an Excel chart.

Please note:

For the import you require the absolute values (not in percent) of the transmission and of the reflection of the front and back for the wavelength range from 250 to 2.500 nm in 2 nm, 5 nm or 10 nm steps.

Additionally the effective emissivities of both surfaces are required.

14 ASHRAE

14.1General

ASHRAE is a professional association of all those working in the heating, cooling, ventilation and air conditioning industry in the USA. The association also specifies how to calculate according to ISO 15099. This standard provides in part two ways to determine characteristic values. ASHRAE then specifies which method is to be used.

In the add-on "ASHRAE", all radiation-physical and thermal parameters can be calculated according to the calculation basis of ISO 15099 and the specifications of ASHRAE. The program structure remains unaffected.

The add-on is only available after corresponding activation:

14.2Boundary conditions

In addition to specifying the calculation basis, ASHRAE also specifies boundary conditions. They are differentiated into summer and winter boundary conditions, whereby the winter boundary conditions must be used to determine the U-value and the summer boundary conditions to determine the g-value (SHGC value). The boundary conditions can be selected under the master data Boundary Condition.

U-value calculations (winter): g-value calculations (summer):

T_i = 21°C T_i = 24°C

T_e= -18°C T_e = 32°C

v_Wind = 5,5 m/s v_Wind = 2,75 m/s

T_r,i= T_i T_r,i = T_i

T_r,e= T_e T_r,e = T_e

I_s= 0 W/m² I_s = 783 W/m²

14.3Emissivity

A corrected emissivity is calculated for the glass panes. The calculation basis for this is taken from NFRC100-2010.

14.4Gases

The gas properties are taken from Annex A of the NFRC 101 and mixed according to the specifications of ISO 15099.

14.5SHGC value

The SHGC value is the North American equivalent of the g-value and is calculated according to NFRC 200-2014.

14.6Printing

The term It has been adapted so that all results from the calculations and also the boundary conditions according to ASHRAE are displayed.

15 Sound database

15.1Glossary

Evaluated sound insulation dimension R¬¬w

Rw is the sound reduction index of a building component, evaluated on the basis of a standard curve (to take human hearing into account).

It is given in dB.

Spectrum matching values C; Ctr

According to EN ISO 717-1, the spectrum adaptation values C and Ctr ("tr" for road traffic "traffic") denote a value in decibels that must be added to the singular Rw to take a specific sound spectrum into account.

The complete specification of the sound insulation of a component is given as follows:

Rw (C; Ctr) = 40 (-2; -5) dB

15.2Product search on the main screen

The sound database can be called up in the main mask by clicking the following button:

You will receive a list of the deposited products for sound insulation:

è Setting the filters and searches

è „Rw", "Rw + C >=" and "Rw + Ctr >="

The required sound insulation value is taken as the minimum value and all products with a sound insulation value higher or equal to the specification are listed..

15.4Determining Rw from database

When searching the database, the type of gas in the SDR is not taken into account.

To determine the sound insulation value for an existing glass structure from the database, proceed as follows:

è Call up product search

è Display of the products that match the current structure

For products to be displayed with a sound insulation film (e.g. "..|PHON..NC"), the design must also include a sound insulation film (e.g. Trosifol® SC Monlayer or Multilayer) in the specification.

1 Default = current structure

2 Larger SDR allowed: products with a larger SDR (orange) are also displayed. Check is off by default because the comparison is on the insecure side.

3 User-defined only displays only products that have been saved by the user.

4 Legendfor the individual colors

The nature of the gas in the SDR is not taken into account.

The structure is identical to the specification, i.e. all thicknesses (glass, SDR and composite layers) are the same.

All thicknesses (glass and SDR) match. The composite layers are not taken into account. For laminated safety glass, monolithic panes of the same thickness are also determined without taking the composite layers into account.

Only monolithic panes of the same thickness are determined for monolithic panes.

At least one glass thickness or SDR is less than the specification. The composite layers are not taken into account.

At least one SDR is greater than the specification and the glass thicknesses are less than or equal to the specification. The composite layers are not taken into account.

21 Downward heat flow

21.1Input

Until now, the installation angle was limited to values between 0° and 90°:

è horizontal, heat flow upwards

è vertical

The input was extended to values from >90° to 180°:

è horizontal, heat flow downwards

21.2Calcultion

21.2.1 Internal convective heat transfer coefficient hci

Note

For calculation according to EN ISO 52022-3, the internal convective heat transfer coefficient hci must be manually adjusted in the boundary conditions.

For DIN EN 673 this is done automatically according to the following description.

So far the following values have been used in WINSLT®:

è Installation angle = 0° (heat flow upwards)

hci = 5,0 W /(m²K) according to DIN EN ISO 6946 (A.4)

è Installaiton angle = 90°
h_ci = 3,6 W /(m²K) according to DIN EN ISO 673 (7.2)

è intermediate values are interpolated

For the heat flow downwards the calculation was extended as follows:

è Installation angle = 180°(heat flow downwards)

h_ci = 0,7 W /(m²K) according to DIN EN ISO 6946 (A.4)

è Values between 90° and 180° are interpolated

21.2.2 Nusselt number

The existing determination of the Nusselt number (calculation according to EN ISO 52022-3 and DIN EN 673) was extended by the determination for an installation angle > 90° and ≤180° based on ISO 15099 as follows

Nu = 1 + (Nu90 - 1) * sin(winkel)

Nu90 Nusselt number for 90° according to DIN EN 673 (6)

sin(90°) = 1 -> Nu = Nu¬90

sin(180°) = 0 -> Nu = 1
