SUSTAINABLE MATERIALS – EXTERIOR

GreenhouseThermalMassCollectionFlooring:BiomasonBiolith®

PrecastConcreteTile

To capture thermal mass, we will use Biolith concrete tiles as flooring in the greenhouse corridor. Biocement technology utilizes bacteria and nutrients to create calcium carbonate, which binds together aggregates in ambient temperatures without using a kiln. Salvageable/reusable in its entirety, 100% recyclable Made locally in Durham, North Carolina, USA

The lifecycle starts with sand and bacteria to create concrete without high energy consumption. Concrete is cast into tiles and applied to an assembly. It can be reused or recycled at the end of the life cycle.

Sidewalk:EnzymaticConstructionMaterial

We have chosen ECM as the exterior flooring material because it is self-healing and can extend the life of the flooring. Enzymatic Construction Material is a self-healing carbon-negative alternative to concrete.

Cracks in ECM can easily be healed. CA enzyme added to concrete powder catalyzes atmospheric CO2 to create calcium carbonate crystals with a matrix-like concrete, and the structure regains up to 97% of its original strength.

When a small crack forms in the enzymatic concrete, the enzyme inside the concrete connects with CO2 in the air, triggering the growth of a new matrix that fills in the crack.

This product is made by mixing concrete powder and CA enzyme to form ECM, a concrete-like material with self-healing properties. ECM can be poured or cast to be used on a project, and at the end of its lifecycle, it can be recycled and repurposed.

ExteriorFaçadePaneling:ReclaimedMushroomBoard

We chose reclaimed mushroom board for the exterior facade paneling to connect the design with nature and the surrounding landscape while incorporating our fire morel mushroom concept. Reclaimed mushroom boards are boards used in mushroom cultivation to line bins. Mushroom bin boards degrade over time and need to be replaced every few decades, but this provides a constant supply of reclaimed material.

Boards are consistently sized and allow for faster installation than reclaimed barn wood. They have smooth surfaces that look great on walls, ceilings, and paneling.

Boards don't need staining or sealant and can age naturally with minimal maintenance.

Mushroom board's lifecycle starts with reused material that is not sent to a landfill but is being used as a decorative element.

RoofTiles:Enviroshake–Enviroslate

We chose Enviroslate for an exterior roofing material for it is aesthetically pleasing natural slate appearance. It is a superior and premium composite roofing product created using 95% sustainable material resulting in durability, longevity, and performance.

Mold, mildew, fungus, rot, insect infestation, and fire resistant.

Withstand severe weather conditions as well as temperature fluctuations and extremes.

Installation is more efficient to natural slate and maintenance free once installed.

Requires installation by trained representative and Enviroshield BSA Underlayment (a waterproof barrier/Class A ASTM E108 rating/exceeds ASTM D9170/180-day UV resistance).

OutdoorSpaces:Techo–BlocPermeablePavers

Techno – Bloc was selected for various outdoor spaces. It reduces cement production in its products with Supplementary Cementitious Materials (SCMs). Slag, a by-product and waste material of metal allows the addition of recycled content to the product while reducing the CO2 footprint. The process minimizes environmental impacts while maximizing performance and durability.

Flood mitigation/permeation of rainwater

Improves water quality through reduction of pollutants, sediment, and phosphorous

Superior thickness, interlocking characteristics; variety of shapes, finishes, and colors (lighter colors reduce heat island effect)

Withstands vehicular traffic, salt-resistant and color-consistent, strong and durable

LEED compliant and locally sourced
