Cristalla’s Green Wall is Changing Color (while staying Green)

As you walk past the south end of the Cristalla, you can’t help but notice a big green wall with soft brown panels creeping up from below.  These are the final steps in constructing a permanent south wall for the building, now underway through CDK Construction Services.

2015 and cristalla

At the time the Cristalla was finished, the south wall was sheltered by an adjoining building set to become the 2015 Second Avenue project. That building was razed during the downtown condo boom, with construction permits filed and things going nicely in 2008 (it was even scheduled to open in 2010). However, like most projects later that year, the recession hit and everything stopped. This left the Cristalla with a now- exposed south wall.  Resulting weather damage finally caused management to repair damages and work on a permanent fix. Now that the south wall will be permanently protected, the Cristalla will no longer have to worry about major maintenance problems or structural concerns—which will also bring a sigh of relief to potential buyers and their lenders.

The green part of the wall is a rain screen manufactured by Knight Wall Systems. Rain screens are exterior infrastructures which sit away from an outside wall’s weather-resistant barrier.  They create a cavity allowing moisture to pass through and away from the building. The resulting airflow between the rain screen and the wall accelerates residual moisture evaporation. There’s also room for additional insulation, which increases energy efficiency and adds LEED credits to the building.

Another LEED feature is the brown part of the wall. North Clad® composite panels have a recycled content of approximately 30%+ pre and post-consumer recycled content. These lightweight panels reflect energy from the sun, reduce heat absorption and are graffiti-resistant. Aesthetically, it’s beautiful material, creating an illusion of a fabric-covered wall. Noel Foster, CDK project manager, added that they’re very pleased with the results.

The Cristalla South Wall project is well ahead of schedule and should be completed in September. The 2015 Second Avenue project is still in play, but no resumption date has been announced.
