The roof uses the pre-grown mats as the base of the green roof system and is complemented by additional plantings to enhance plant di- versity as well as ecological resilience using a mix of sedum and native plants. More than 11 miles of sustainable, water-efficient irriga- tion lines were installed, and well as 14,000 cement pavers for firebreaks and roof pro- tection. And though that project called for 50% of recycling materials, Tecta set a goal of recycling 100% of the old roof, resulting in approximately 450 tons of existing rock and 590 tons of existing pavers, 140 tons of existing roofing membrane and more than 60 truckloads of existing roof insulation. The green roof captures an estimated one- million gallons of storm water per year, will mitigate urban heat island effect by reducing the roof temperature up to 80 degrees Fahr- enheit, and has a waterproofing membrane anticipated to last 40 years. At the Heaquarter Honda in Clermont, Florida, Tecta deployed the full range of environmental roof-top concepts in a land- mark LEED Platinum project complement- ed by applications in reflective membranes, day lighting, solar-energy generation and a vegetative roof system. The energy output, estimated at 470kWH or better of alternat- ing current per day, is displacing a minimum of 10% of the facility’s current demand on
