The Crown Towers Sydney has achieved 6-Star Green Star Design with New Solar Project Using S-5-Z Clamp!

Project at a Glance


The Situation & Results

The Crown Towers Sydney wished to discreetly integrate solar
into the design of its hotel as part of its greater plan to achieve a
6-Star Green Star rating, representing the world’s best practices
in sustainability.

They chose S-5! clamps because they provided the best fit for
the seam, allowing maximum solar placement on the rooftops
with unsurpassed and certified holding strength to resist the
area’s design wind speeds.

What Worked?

They chose the S-5-Z Clamp and the S-5-Z Mini clamps (approximately 1,200) to support an aluminum flat plate on 0.9 mm and 0.5 mm thick KingSpan, KingZip Linea aluminum standing seam metal roofs, with on-site renewable energy generation including including 70kW of solar PV.  The S-5! non-penetrating seam clamps are specially developed to fit profiles featuring a round “bulb” seam configuration, and therefore provided the best fit for the seam, allowing for maximum solar placement on the rooftop with unsurpassed and certified holding strength to resist design wind speeds. In this case, the attachment system was designed to withstand a 1000-year windstorm.

With its new solar array and other environmental elements, the Crown Towers Sydney has achieved a 6-Star Green Star Design and As-Built-Rating under the Green Building Council of Australia’s certification scheme.

Long-Term Outlook

The Crown Towers Sydney was able to achieve the quality look they wanted with S-5! solar attachments designed and engineered for the hotel’s KingZip standing seam profile to last the life of the roof.

S-5! Products Used

The S-5-Z (“Z” stands for Zip-Rib) is specially designed for round “bulb” seam configurations. Mount snow guards and other heavy-duty applications to “bulb” seam configurations, such as Zip-Rib®BEMOKalzip® and other similar profiles. Easily install the two-piece clamp anywhere along the length of the rib.

The Z Mini clamp is a more economical solution for lighter-duty attachments where Herculean holding strength is not required. The Z Mini clamp is a bit shorter than the standard Z with one setscrew rather than two.
