About Our Collections

The goal of our collections is to help promote transparency in the material ingredients of building products by fostering knowledge and awareness of products and materials for which life-cycle information is available, and that have environmentally, economically, and socially preferable life-cycle impacts.

Keep an eye out for the following symbols:
A Healthier Affordable Building Product

Products with the designation of "Healthier & Affordable" were specified and installed in at least one of our Case Studies of healthier affordable housing.

Available at the Donghia healthier Materials Library

The Donghia healthier Materials Library library is open to Parsons student and faculty. Learn more about access and opening hours here.

Low Embodied Carbon

“Embodied Carbon” is the total amount of carbon emitted during the process of making a material. *HML refers to a manufacturer's EPD to determine whether a product's A1-A3 carbon emissions falls within HML's threshold for Low Embodied Carbon.

New Product

This product has been added to the collection within the past six months.

Ingredient Disclosures

There are several ways of evaluating a material’s health that we include with product information. Disclosures are reports by manufacturers about product ingredients, impacts, or other attributes.

Key Disclosures include:
Health Product Declaration (HPD)

A voluntary technical specification for reporting information on product contents and associated health information, intended to be the health-analogue to Environmental Product Declarations (EPDs).

Declare Label

Declare is a transparency platform and product database that answers three questions: 
  1. Where does a product come from?
  2. What is it made of?
  3. Where does it go at the end of its life?

Environmental Product Declaration (EPD)

A standardized format for communicating the environmental effects associated with a product’s raw materials extraction, energy use, chemical makeup, waste generation, and emissions to air, soil, and water.

Safety Data Sheet (SDS)

A reporting format that provides basic information about a material’s chemical ingredients, the potential safety hazards to installers, and recommended practices for installation.

Wool Batt Insulation

Low-Embodied Carbon Material

Sheep's wool provides a healthy and comfortable choice for insulation. Wool is naturally flame resistant. Additionally, wool's unique structure (a hydrophobic exterior and hydrophilic interior) allows it to absorb up to 35% of its weight in moisture from a room. When used as insulation, this gives wool the unique capacity to manage both humidity and temperature. Batt insulation requires the material to hold its shape. Traditional batts are held together with chemical additives. Havelock Wool's uses needle punching to hold their product together, avoiding toxic chemicals.

Per Havelock's EPD, this product meets HML's criteria for low embodied carbon. Havelock's wool insulation are produced in Reno, NV, making its application most impactful on projects in western United States.

*Note: Havelock's Loose Fill Insulation has R values of 4.3 and also meets HML's criteria for low embodied carbon.

Rabbit Hatters Fur

Available At the Donghia Materials Library

Cortadoria, a company based in Portugal, uses the surplus from the rabbit meat industry to source their super-soft rabbit fur. Their Rabbit Hatters Fur is Cradle to Cradle Gold Certified. The product is chemical-free, avoiding certain harmful additives that are traditionally used to wash and degrease fur. Because the material is diverted from landfills, and because of the minimal energy required to process rabbit skins, Cortadoria’s Rabbit Hatters Fur provides a sustainable alternative to traditional furs and hatting materials.

Note: The C2C certification has expired and will not be recertified.

The manufacturer confirms that, however, the Cradle to Cradle vision remains the inspiration and guidance of the company.

Honeybee Bio Resin

Available At the Donghia Materials Library

Propolis is a biodegradable resin that honey bees collect from different trees and use as a sealant for unwanted open spaces in the beehive. Its color depends of the forests and botanical sources used in the collection by the honey bees. The most common one is brown, but there are plenty of variations in colors and properties. This particular black propolis is from rubber trees.

*NOTE: This material is currently sourced from only 500 beehives, yielding only 30-50 kilograms per year. It is thus a very precious and unique material.

Manufacturer
Marléne Huissoud

Material composition*

The propolis, at its first stage, is a mix of between 50 to 150 different components (wax, balsams, resins, pollen, essential oils…). Refining by boiling in water allows the impurities to leave the propolis and be used as a precious finish on art pieces and furniture.

Microsilk

Available At the Donghia Materials Library

Bolt Threads' Engineered Silk is biofabricated by mimicking the DNA in Spider Silk. They develop proteins inspired by the DNA (no spiders are actually involved) and put them inside of yeast.

The yeast produce silk protein in a liquid form during fermentation—very much like the beer-making process. After some processing, the liquid silk protein can be turned into fiber through wet-spinning, which is the same way fibers like acrylic and rayon are made.

Sheep Wool Insulation

Black Mountain's sheep wool insulation provides an excellent alternative to manmade batt insulation products. The product is designed for use in loft, rafter, internal wall, and inter-floor applications. Because it is a natural material, this wool insulation is completely biodegradable and requires 85% less embodied energy to produce than manmade products. Additionally, wool actively improves indoor air quality by absorbing carbon dioxide and toxic gasses such as formaldehyde and is naturally flame retardant.

The R-value range is declared as 6.5-49.
