CETCO Newsletter: LEED™ Products
CETCO Building Materials Group has been participating in this program for a number of years working on a variety of LEED certified projects nationwide. LEED is a self-assessing system designed for rating new and existing commercial, institutional, and high-rise residential buildings. It evaluates environmental performance from a "whole building" perspective over a building's life cycle, providing a definitive standard for what constitutes a green building.
CETCO provides several products that qualify as LEED certified products. The purpose of the program is to evaluate the whole building from an environmental performance perspective over the building's life cycle to determine if the building is a "green" building.
CETCO's LEED products include:
- Volclay Ultraseal BT
- Volclay Ultraseal SP
- Volclay Voltex
- Volclay Voltex DS
- Volclay Panels
- Strataseal HR Assemblies
- LDC 60 Fluid Applied Waterproofing
- Aquadrain 10X
- Aquadrain 15X
- Aquadrain 15XP
- Aquadrain 18H
- Aquadrain 20H
- Aquadrain 30H
- Aquadrain 100BD
- Waterstop RX
Under the program a building is evaluated based on six primary categories including sustainable site, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, and innovation and design process. Points or credits are awarded for the various line items in each of the above categories, and buildings are deemed LEED buildings if they earn a certain n umber of points. The rating is as follows: LEED Certified with 26-32 points; Silver with 33-38 points; Gold with 39-51 points; Platinum with 52-69 points.
One of the credits available in the first category -- sustainable sites -- is "Landscape & Exterior Design to Reduce Heat Islands/Roof" (credit 7). The intent of this credit is to "reduce heat islands (thermal gradient differences between developed and undeveloped areas) to minimize impact on microclimate and human and wildlife habitat." As such, one point (of the 69 points available in the program) is available if the building uses a roof with both high reflectance and high emissivity.
The requirement states: "Use Energy Star Roof-compliant, high-reflectance AND high emissivity roofing (initial reflectance of at least 0.65 and three year aged reflectance of at least 0.5 when tested in accordance with ASTM E903 and emissivity of at least 0.9 when tested in accordance with ASTM 408) for a minimum of 75% of the roof surface; OR, install a "green" (vegetated) roof for at least 50% of the roof eare"
