Applications: High Wind and Hurricane

High Wind and Hurricane

Models G and GB

Greenheck is leading the High Wind Standard for roof top fans and ventilators. Forceful winds and wind-borne debris are the cause of most hurricane damage. Hurricane winds start at 75mph. At speeds over 150mph, wind can exert a force of 75poundspersquarefoot of pressure or over 900pounds on a fan and curb. Forceful winds are not the only problem, wind-borne debris can also cause detrimental effects to objects and structures. High winds and extreme forces are the cause of most storm damage. By analyzing calculations, computer simulations, actual testing, and other standards—Greenheck developed the High Wind Standard.

Protocols designed to protect against wind-borne debris and severe wind loads:

Structural Performance Load

Miami-Dade County Test Protocols

Miami-Dade NOA Numbers

Texas Department of Insurance

State Licensed P.E. Calculations

Certified Independent Third-Party Testing

A static load that is 1.5times the design load (91.5 pounds per square foot of pressure) is applied both positively and negatively to simulate wind force loads in each direction. Structural Performance per Dade County Protocol TAS-202 (ASTM-E330).

Greenheck has gone the extra mile and worked with Miami-Dade County to design a High Velocity Hurricane Zone standard for rooftop fans. The model USGF has become the first rooftop fan certified and approved by the Miami-Dade Building Code Compliance office and Texas Department of Insurance for use in hurricane zones.

The certifications can be viewed on the Miami-Dade County Web site under the NOA numbers listed below. Models G and GB are the first downblast aluminum fans in the industry that have received a Miami-Dade NOA for high wind (150 mph) and hurricane zones. Miami-Dade NOA 08-0519.02 for models G and GB.

The certifications can be viewed on the Texas Department of Insurance Windstorm Web site under TDInumberRV-42.

Structural calculations performed by a licensed Professional Engineer (P.E.) on models G and GB include Finite Element Analysis (FEA) and a stamped P.E. report of the fans compliance to ASCE 7-02 Minimum Design Loads for Buildings and Other Structures Standard and the Florida Building Code. The ASCE 7-02 Standard meets the IBC, Florida and Miami-Dade codes. The models have been proven to withstand winds in excess of 150 mph (61 psf).

Each of the Greenheck models have been subjected to extensive testing procedures. The G and GB have been certified by an independent third party to the ASTM E-330 Static Pressure Difference Standard, Florida Building Code Test Protocol TAS-201 (large missile impact), 202 (static pressure difference) and 203 (cyclic pressure) Static Pressure Difference.

Computational Fluid Dynamics (CFD)

Finite Element Analysis (FEA)

All Greenheck high wind models have been analyzed using Computational Fluid Dynamics (CFD). CFD is computer software designed to simulate the flow of high speed (150 mph) winds over the surface of objects. The software records the force profile exerted on the fan so it can be utilized in Finite Element Analysis (FEA).

Utilizing the results from CFD analysis Greenheck can accurately predict the stress, strain, and deflection resulting from high wind loads. Greenheck high wind units have been proven to withstand 150 mph winds through Finite Element Analysis utilizing CFD results.

Applications: Severe-Duty Roof Curbs for High Wind and Hurricane

High-wind and severe-duty roof curbs are provided as standard with models G and GB. The severe-duty roof curb models can ship separately to allow for ﬁnal ﬁnishing of the roof prior to the fan arrival and installation.

Model GPF — This roof curb is specifically

designed for high wind applications up to 150 mph (61 psf), used on fan models G and GB. Standard height is 12inches (305mm), fully-welded straight sides with a 5-inch flashing flange. GPF is available up to 24inches (460mm) in height to meet greater height requirements.

Models SD and SDP — The severe-duty curbs

are specifically designed for high wind applications up to 150mph and used on models G and GB fans. Model SD is for use on flat roofs and model SDP for pitched roofs. They are attached directly to the building structure with extremely high structural design load requirements. Maximum design load is 130psf. The severe-duty curbs are 12gauge coated steel with a 13⁄4-inch lip on the top and a 4-inch flange on the bottom. Available heights include 12–24inches. Heights greater than 18inches are reinforced in the interior with 12gauge x 2-inch angles.

Installations

Fan Inlet Connections

In order to assure proper fan performance, caution must be exercised in fan placement and connection to the ventilation system. Obstructions, transitions, poorly designed elbows, improperly selected dampers, etc., can cause reduced performance, excessive noise, and increased mechanical stress. For performance to be as published, the system must provide uniform and stable airﬂow into the fan.

Good

Poor

Dampers must open fully. Use motorized dampers in low airﬂow applications to reduce losses.

Wheel Rotation

Direction of rotation is very critical. Rotation in the wrong direction will result in excessive horsepower, possible motor burnout, and increased noise levels. Check rotation by energizing the unit only momentarily. The rotation should be the same as the rotation decals afﬁxed to the unit and is clockwise when viewed from the top of the unit.

Poor

Avoid sharp turns or entrance conditions which cause uneven ﬂow. Use turning vanes in elbows to reduce adverse effects.

Good

Provide uniform airﬂow at fan inlet to assure optimum performance.

Provide uniform airﬂow at fan inlet and through the damper to assure optimum performance.
