Denver Botanic Gardens

Roofing, Solar, Waterproofing, Garden

Few places in our city are as beloved as the Denver Botanic Gardens. Over the years, Douglass Colony has been lucky enough to help expand and grow the Gardens with two separate projects as they have continued to evolve.

Working on the Mordecai Children’s Garden was particularly rewarding. The team focused on the 20’000 sq. ft. garden roof, applying an American Hydrotech 215mil hot fluid-applied rubberized asphalt membrane system. This system served to waterproof everything, and also included a root barrier to protect the roof, as well as multiple layers of insulation, a water retention drainage mat and pre-engineered soil.

The result was a safe, sustainable foundation for the garden to be planted in that will last for years to come. Today’s visitors are encouraged to explore the many plants and natural world through hands-on experiences and play.

More recently, Douglass Colony installed solar panels on the Freyer-Newman Center. The center was created to celebrate the fusion of science and art, housing classrooms, galleries, herbaria, and more. To further that celebration, the Douglass Colony solar team installed a 63kW rooftop array, REC solar modules, and SolarEdge inverters — keeping the center sustainable. The project has already had a large impact. In under 9 months CO2 emissions were reduced by 77 metric tons. That’s the equivalent of 8’261 gallons of gas or 16 acres of trees saved.

With decades of experience and expertise, Douglass Colony continues to bring client visions to life for the enjoyment of everyone.
