Use of Wind Deflectors on Roof NSHEVs

Use of Wind Deflectors
on Roof NSHEVs
Powering your ideas!
Introduction
The use of wind deflectors offers many
advantages over conventional solutions. For example, their use eliminates the need for a wind directiondependent control system. The result:
A potential reduction in relevant
procurement costs of up to 50%
thanks to the massive savings associated with NSHEVs.
And it is that simple …
Surely you’re thinking: That is exactly my goal, but how can I make it
happen? This guideline is a simple
instruction how to reach your goal
quickly and easily.
The guideline is divided into three
chapters. Chapter 1 covers the basic
principles. For example, the following
questions are answered there:
■Why are wind deflectors required
on roof NSHEVs?
■What does the standard specify?
■What are the advantages of D+H
roof smoke exhaust systems in
conjunction with wind deflectors?
■How is a NSHEV with a wind
deflector calculated?
■Which dimensions are important for
the calculation, and how are they
determined?
In Chapter 2, you will find instructions, based on a practical example,
on how to calculate a NSHEV with
wind deflector for your building. In
the Appendix, you will also find all
required diagrams for calculating roof
NSHEVs with wind deflectors.
Glass or sheet metal? That is the
question in Chapter 3, which also
provides details on ordering wind
deflectors, using a practical example.
Do you have any further questions?

1.
Why should you use wind deflectors on roof NSHEVs?
Basic principles
DIN EN 12101-2 is a product standard
which governs the testing and certification of NSHEVs.
It states:
■ For roof NSHEVs, the aerodynamic
flow rate coefficient is always determined both with and without taking
the crosswind into consideration.
For this, the lower value with crosswind influence should always be
specified.
■ If NSHEVs are equipped with
wind deflectors, the wind deflectors must be located at least 80
mm away from any NSHEV parts.
Furthermore, the wind deflectors
must be mounted in a manner
that prevents the formation of any
adverse snow or ice accumulation,
with regard to the opening process.
The new draft of the prEN 12101-2
standard also defines the terms “wall”
and “roof”:
■ Roofs = exterior building surfaces
with an inclination of 60° or less,
relative to the horizontal plane.
Shed roofs and lighting strips shall
be regarded as part of the roof, irrespective of their inclination.
■ Walls = exterior building surfaces
with an inclination of 60° or more,
relative to the horizontal plane.
The use of a sidewind dependent
control for roof NSHEVs does not offer
safe smoke exhaust and is therefore
not allowed according to the current
and future norm.
For roof NSHEVs, the increase in
aerodynamic efficiency when subjected to wind is typically realised using
wind deflectors which guide the local
wind flow over the opened area of the
NSHEVs.
What are the advantages of D+H roof smoke exhaust systems in connection with
wind deflectors?
■No wind-direction dependent control system is required, thereby
eliminating doubling of NSHEVs.
■DIN EN 12101-2 certified
■A visually appealing glass solution
and an inexpensive sheet metal
version are available.
■Universal installation kits are
available for glass wind deflectors

Calculation of a NSHEV with a wind deflector
Because the NSHEV should always
be viewed as a unit, the wind deflector
is considered to be part of the NSHEV.
The height of the wind deflector is
always calculated in conjunction with
the calculation of the NSHEV.
Influencing variables for calculating a NSHEV
All relevant variables are defined in
the Technical Specification and can be
derived from the specification.

Example of calculating a NSHEV with a wind deflector
A building with a specified area of 15 m2,
for which smoke must be removed
exclusively via a monopitch roof, is
used as an example. The roof inclina1
tion is 10°. The Schüco® AWS 57 RO
roof windows have a width of 1.2 m and
height of 3 m.
They must be equipped with wind
deflectors and are opened to 30°.The
number of required NSHEVs and the
height of the wind deflector must be
calculated.
Specify roof inclination/roof type
The available roof inclination and roof
type can be found in the Technical
Specification. The diagrams in the
Appendix of the listed Chapters must
be used for the calculations, depending on the roof inclination and roof
type.

Dimensions of NSHEVs
The width and height of the NSHEV
can be found in the Technical
Specification.
3
Opening angle of the NSHEV
Determine the opening angle of the
NSHEV if it is not specified in the
Technical Specification. The opening
angle is dependent on the stroke of
the drive and can be calculated using
the D+H Calculator*. Additionally the
stroke can be determined by the
opening angle.

x = s ystem vendor-specific exhaust
dimension from Table 1 in Chapter 3.4
of the Appendix.
Referring snow load calculation
please contact our EN-Team!
Example:
Height of the wind deflector = 250 mm
(The dimension is calculated using the
data in Diagram 2 in Chapter 3.1.1)
Example:
x = 135
W/H = Bclear space / Hclear space
= (1.2 – 0.135) / (3 – 0.135)
= 0.37
Therefore, the width/height ratio is 0.37.
Aerodynamic flow rate coefficient (CV)
The aerodynamic flow rate coefficient,
depending on the width/height ratio
and the opening angle of the NSHEV,
can be determined from the corresponding diagram in Chapter 3.1.1.

Width/height ratio of the NSHEV
Now, calculate the width/height ratio
(W/H) using the values from step 2.

Example:
30° opening angle
Height of the wind deflector
Determine the height of the wind
deflector, based on the width and
height of the NSHEV, from the corresponding diagram in the Appendix.

Example:
Width (W) = 1.2 m
Height (H) = 3 m
Example:
Width/height (W/H) = 0.37
30° opening angle
The aerodynamic flow rate coefficient
is 0.43.

Geometrically available area (Av) of the NSHEV
Av = HClear space x WClear space
= (H – x) x (W – x)
x = s ystem vendor-specific exhaust

Example:
Aa = 0.43 x 3.05 m² = 1.3 m²
The effective aerodynamic area of
the NSHEV is 1.3 m2.
Number of required NSHEVs
n = AAroof /Aa

Glass or sheet metal?
Up to a height of 300 mm, a wind
deflector can be manufactured in glass.
For wind deflectors between 300 mm
and 600 mm, sheet metal must be
used. Glass is the visually appealing
option, while sheet metal is the costeffective alternative.
8
You have decided on a glass wind deflector?
Then continue with steps G1 and G2.
Or do you want a sheet metal wind deflector?
Then, continue with step B1.
G1 Glass wind deflector
The glass is not part of the D+H scope
of supply! A manufacturing drawing
is available for ordering the glass.
Please download the AD00221 drawing from the Intranet. The AD00221
drawing can be found on page 21.
Please enter the following information
on the drawing:
■ Length (l) = height of the NSHEV in mm (from step 2, Chapter 2)
+20 mm
Example:
Length (l) = 3,000 mm + 20 mm
= 3,020 mm
The length of the individual glass must not exceed 2,500 mm.
Therefore, the glass must be cut.
Therefore: Length (l) = 1,510 mm (number of glass panes doubles)
■ Height h = height of the wind deflector (from step 4, Chapter 2)
Example:
Height (h) = 250 mm
The height of the individual glass must not exceed 300 mm.
■ Number of glass panes = 2 x number of NSHEVs
(from step 9, Chapter 2)
Example:
2 x 12 pieces = 24 pieces
The number of glass panes doubles because the glass needs to be cut
= 48 pieces
The completed drawing can now be
sent to a glazier and the material can
be ordered in the required quantities.
It is very much recommended to fur-
nish the glass panes with drill holes
and secure with screws. In this case
the glass mountings are not necessary. For this, the maximum allowable
distance between the drill holes is 460
mm (see WDF instructions for use).
G2 Installation kits
Two console sets are required for
fastening glass wind deflectors: One
for the corner mounting (WDF-BS001CM, Item No. 27. BAA. ZU) and one
for middle mounting (WDF-BS002MM, Item No. 27 BAB. ZU).
■ Number of WDF-BS001-CM installation kits = number of NSHEVs
Example:
12 NSHEVs = 12 x WDF-BS001-CM installation kits, to be ordered from
D+H
■ Number of WDF-BS002-MM installation kits
= ( height of the NSHEV in mm (from step 2, Chapter 2)/460 mm) x
number of NSHEVs
The result is always rounded down and multiplied by the number of NSHEVs.
The distance between the installation kits must not exceed 460 mm!
Example:
(3,000/460) x 12 = 6 x 12 = 72 WDF-BS002-MM installation kits
9
B1 Order sheet metal wind deflector
The sheet metal wind deflector is not
part of the D+H scope of supply! A
combined installation and manufacturing drawing is available for ordering
and installing the sheet metal wind
deflector. A complete sheet metal wind
deflector consists of one piece of sheet
metal, 2 side gauges and 2 T-profiles.
Please download the AD00222 drawing from the Intranet. The AD00222
drawing can be found on page 18 et
seqq. Please enter the following information on the drawing:
■ Page 19: Length (l) = height of the NSHEV in mm (from step 2, Chapter 2)
+ 100 mm
Example:
Length (l ) =
3,000 mm +100 mm
= 3,100 mm
The length of the individual sheet metal must not exceed 2,600 mm.
Therefore, the sheet metal must be cut.
Therefore: Length (l) = 1,550 mm (number of sheet metal pieces doubles)
■ Page 19: Height h = height of the wind deflector (from step 4, Chapter 2)
Example:
Height (h) = 250 mm
The height of the individual sheet metal must not exceed 600 mm.
■ Page 19: Dimension X = see Table 2 (in AD00222)
Example:
Height (h) =
250 mm dimension (X)
= 50 mm
■ Page 20: Dimension Y = height of WDF/2
Example:
Dimension (Y) = height (h) /2
= 250 mm /2 = 125 mm
■ Page 18: Length of the T-profile = see Table 1 (in AD00222)
Example:
Height (h) = 250 mm
Length (l) of the T-profile = 195 mm
■ Number of sheet metal pieces = 2 x number of NSHEVs
Example:
2 x 12 pieces = 24 pieces
The number of sheet metal pieces doubles because the sheet metal needs
to be cut = 48 pieces
■ Number of side gauges = 2 x number of sheet metal pieces
Example:
2 x 48 pieces = 96 pieces
■ Number of T-profiles = 2 x number of sheet metal pieces
Example:
2 x 48 pieces = 96 pieces
You now have all information for your NSHEV!
Simply send the complete drawing to the selected window manufacturer and order the corresponding quantities of
sheet metal, side gauges and T-profiles.
