Patent number: 8161692Abstract: An apparatus attached to the roof perimeter to mitigate wind-generated vortices and uplift loads on the roof perimeter area of a building, applicable for both new constructions and retrofits of existing buildings. The apparatus comprises at least one face portion having face perforation and/or edge serration for increasing small-scale turbulence entrainment, equalizing pressure and disorganizing edge shear layer vorticity, and thus disrupting vortex formation. A roof edge vortex suppressor is preferably mounted along the entire circumference of a roof perimeter.Type: GrantFiled: December 21, 2010Date of Patent: April 24, 2012Assignee: Renscience IP Holdings, Inc.Inventor: Jason JianXiong Lin

Publication number: 20120000145Abstract: A roof ridge vortex suppressor may include a base portion configured to be attached to a pitched roof having sloped, generally planar first and second surfaces intersecting with one another at a roof ridge. An upright member may extend from the base portion and may be configured to extend generally vertically upward and away from the roof ridge. The upright member may include a plurality of perforations. First and second segments may extend away from the upright portion. The first segment may be configured to extend generally horizontally in a first direction, and the second segment may be configured to extend generally horizontally in a second direction facing opposite the first direction.Type: ApplicationFiled: June 30, 2011Publication date: January 5, 2012Inventor: Jason JianXiong Lin

Publication number: 20120000144Abstract: A vortex suppressing system is disclosed. The system is associated with a pitched roof having sloped, generally planar first and second surfaces intersecting with one another at a roof ridge. The system may include a fascia member attached to a perimeter of the roof. The fascia member may extend generally outwardly away from the perimeter of the roof, and may be generally curved to define a generally arch-shaped cross-sectional shape of an outer face of the fascia member. Additionally, the system may include an assembly, which may include first and second end portions attached to the first and second surfaces, respectively. In addition, the assembly may include a bridging portion extending over the roof ridge and from the first end portion to the second end portion. The bridging portion may have a generally curved outer surface, which may be substantially symmetrical about a plane generally parallel to the roof ridge.Type: ApplicationFiled: June 30, 2011Publication date: January 5, 2012Inventor: Jason JianXiong Lin

Patent number: 7836642Abstract: An assembly attached to the roof perimeter to mitigate wind-generated vortices and uplift loads on the roof perimeter area of a building, applicable for both new constructions and retrofits of existing buildings. The assembly comprises an overhung screen portion preferably having face perforation and outer edge serration for equalizing pressure and disorganizing shear layer vorticity, and thus disrupting vortex formation. A roof edge windscreen is generally mounted onto an existing fascia or bargeboard. As an option appropriate for new constructions, it can also be mounted directly onto a framing member in place of fascia or bargeboard.Type: GrantFiled: July 23, 2005Date of Patent: November 23, 2010Assignee: Renscience IP Holdings Inc.Inventor: Jason JianXiong Lin

Patent number: 7827740Abstract: An aerodynamic system attached to the outer side of the roof perimeter edge to mitigate wind generated vortices and uplift loads on the roof perimeter area of a building, applicable for both new constructions and retrofits of existing buildings. A roof edge guard is generally installed alongside a roof edge, and mounted onto an existing fascia or bargeboard. As an option most appropriate for new constructions, it can also be mounted directly onto a roof frame member in place of fascias or bargeboard. The configuration modifies the cross-sectional shape of otherwise abrupt roof edges that tend to generate strong vortex during high winds.Type: GrantFiled: February 6, 2009Date of Patent: November 9, 2010Assignee: Renscience IP Holdings Inc.Inventor: Jason JianXiong Lin

Patent number: 7025671Abstract: A surface mounted device includes a hollowed base body mounted on a building or vehicle exterior, and a hollowed raised body supported and secured on the base body with hollowed elongated members. A free space is formed between the base body and the raised body. An opening or openings are facilitated on, and near the center of, the lower surface of the raised body, to connect the free space with the internal space of the base body through the hollowed raised body and hollowed elongated support members. The base body and the raised body are configured in such a way that the free space between them is narrower at the center than along the perimeter. This forms an airflow path that is first contracting towards the center and then expanding afterwards for any approaching wind direction, providing a venturi mechanism.Type: GrantFiled: August 27, 2004Date of Patent: April 11, 2006Inventor: Jason JianXiong Lin

Patent number: 6606828Abstract: A roof edge fascia or coping cover having an aerodynamic exterior shape mainly comprising a lower face portion, an intermediate face portion, and a top face portion. The lower face portion is either generally vertical, or sloping or curving upwardly and outwardly, forming an angle within 60° to the vertical outer wall surface of a building. The top face portion, of a substantial lateral size, is generally disposed within ±25° from horizontal. The intermediate face portion, having at least one segment of a substantial lateral size sloping or curving upwardly and inwardly, connects the lower and top face portions. Slope changes at a junction between any two adjacent face portions, or adjacent segments thereof, are generally less than or equal to 50°.Type: GrantFiled: December 6, 2001Date of Patent: August 19, 2003Inventors: Jason Jianxiong Lin, Liddy Miaoli Chen
