The Sun Petal Modular Shading System is an award winning shading system that is easy to install and adds a beautiful architectural feature to buildings.  It is designed to cut air conditioning costs significantly by eliminating direct sunlight into the building during periods when cooling systems have their highest load.  The system is passive and needs virtually no maintenance once it is installed and can be installed on new or existing buildings.

Direct Sunlight Heats Up Those Cool Spaces

Energy prices continue to rise. Summers are lasting longer with higher temperatures than ever and the air conditioning units continue to be one of the most inefficient mechanical systems in buildings.

When we are hot outdoors we seek the cool shade below a tree canopy. Now, there is a cost affordable way to provide that same cool shade to all of our buildings, the Sun Petal Modular Shading System.

Below are a couple of photos of the prototype that we recently have fabricated.

The U.S. Department of Energy has determined that exterior shades can reduce solar heat gain in the summer by 65% on south-facing windows and 77% on west-facing windows.

Passive Shading

The Sun Petal Modular Shading System is designed to prevent direct sun light from coming into windows when the temperature is at its hottest, and the cooling system is working its hardest. The shading system is designed with a unique, latticed structure, which keeps direct sunlight from passing through windows. This kit of parts lightweight design and simple attachment mechanism ensures easy installation and virtually no maintenance. The angled, latticed approach also enables water and snow to pass through the system so it can be left in place for all seasons of the year. Likewise the robust design approach ensures that strong winds will not create the uplift that typically occurs from other shading systems.

The modular design of the Sun Petal Shading System affords endless combinations for new construction and retrofitting existing buildings.

Below are several simulations to show some of the configurations that are possible with the modular design.  Please watch our video to view some other possible configurations.

In addition to reducing heat loads, the system blocks ultraviolet rays from fading interior artwork, finishes and furnishings.  At nighttime, the Sun Petal diverts interior artificial light from the night sky (actual prototype mounted).

Project Schedule - Based on estimates from suppliers and partners, we plan to deliver the Sun Petals in late July.  We expect to have our tooling completed by the end of April.  We will test first runs of the product in early May, and we expect to be producing and fulfilling orders in time to enjoy these systems by mid-summer.

Rewards - Sun Petal Modular Shade System(s) as described in project rewards, Sun Petal Stay Cool T-shirt and Sun Petal Shade Cap shown below.

Risks and challenges

The Sun Petal Modular System has been designed and prototypes have been built. With your help, we will be fabricating the necessary tooling and the initial run of the product. As always with a new product, there is the chance of delay from fabrication issues. We do not expect cost issues to be a problem, since we have secured quotes for all tooling and product piece part costs from reputable suppliers in our area.
