Vande Hey Concrete tile contributes toward satisfying LEED ® credits and toward sustainable design as follows

EA Credit 1 - Optimize Energy Efficiency
VHR Concrete roof tiles have the ability to absorb and release heat via thermal mass effect.1 The batten system under the tiles creates an eave to ridge air flow reducing heat transfer to the attic, reducing heat transfer to attic by up to 50% (Oak Ridge National Laboratories)2.
MR Credit 1.1 - Building Reuse - Maintain Existing Walls, Floors and Roof
VHR Concrete tiles last the lifetime or more than the building they are installed on. They have a limited lifetime transferrable warranty. While initial installation cost is higher, the life cycle cost can be lower as other roofing materials that need to be replaced 2-3 times over the life of the building.
MR Credit 2 - Construction Waste Management
Leftover concrete tile can be crushed and used as fill.1 Vande Hey offers a complete roof package system of all materials. Waste is reduced by optimizing flashing lengths, instead of shipping 10’ pcs. .
MR Credit 3 - Material Reuse
Concrete tiles can be salvaged from an existing area and reinstalled on a new area or another project.1
MR Credit 4 - Recycle Content
All Vande Hey Concrete tile uses an 80% Portland Cement 20% Pre-Consumer Recycled Slag Cement mixture.
MR Credit 5 - Regional Materials
All materials used in production are manufactured/extracted within 300 mi of the plant. This will also apply if project is within the 500 mi radius from plant.
SS Credit 7.2 Heat Island Effect - Roof

The Portland Cement Association found that 135 concretes tested for solar reflectance had an SRI of at least 293. The lowest SRI is from concretes composed of dark fly ash. The solar reflectance of slag cement is greater than Portland or fly ash.

Vande Hey Raleigh uses an 80% Portland Cement 20% Slag Cement mixture in all tile production which raises the initial SRI3. Individual colors have not been tested, so it is not known how much solar reflectiveness is reduced by the introduction of oxide.

Vande Hey Raleigh provides additional Sustainable Design elements

Labor can be reduced by eliminating time spent bending flashings or leaving to pick up extra materials needed. This can also reduce vehicle use.

Moisture Control- When properly installed, Vande Hey’s flashings direct water away from walls and protrusions reducing the chance of leaks in interior.

Durning production, imperfect tiles are immediately recycled back into the mixer.
