INTENCIÓN
To design buildings that minimize energy use to reduce the environmental damage caused by resource extraction, air pollution, and greenhouse gas emissions and to facilitate the transition to a clean energy future.
CONTRIBUCIÓN
BASWA system panels offer a range of high R-values relating to the total panel thickness. BASWA finishes are made with recycled marble sand and are cool to the touch. Marble has a natural ability to maintain a cool temperature due to its thermal properties, and quickly absorbs heat and then releases it slowly, creating a cooling effect.

To eliminate ozone depletion and global warming potential, and support early compliance with the Montreal Protocol, including the Kigali Amendment, while minimizing direct contributions to climate change.
CONTRIBUCIÓN
BASWA Cool is a draft-free, noise-free heating and cooling system with excellent sound absorption with embedded, large-scale water-transporting capillary system providing consistent thermal control at a fraction of the energy typically used in a forced air system, and without the negative effects on the ozone typical with air conditioning systems.

To reward project teams for selecting products from manufacturers who have disclosed sustainability information about their products and optimized their products across multiple criteria areas.
CONTRIBUCIÓN
BASWA utilizes natural plant fibers, recycled glass, post-industrial recycled marble sand, organic binders, and minimal synthetic materials to produce the most sustainable systems available.
Each BASWA system offers unique sustainable solutions. BASWA Phon, BASWA DTG, and BASWA Basic panels are made with recycled glass, reducing landfill waste and the demand for new raw materials. BASWA Natural panels are made exclusively from hemp and flax fibers sustainably cultivated by regional farmers who adhere to strict environmental standards. BASWA finishes are made of post-industrial recycled marble sand that helps form a micro-porous surface that sound can pass through to be absorbed within the system panel.
Drawing on 100% renewable and locally generated electricity from hydropower in the panel production process requires less energy and emits less greenhouse gas. Using only water instead of solvents in our products helps keep harmful VOCs out of the atmosphere.
Construction & Demolition Waste Management
1-4 points
INTENCIÓN
To reduce construction and demolition waste disposed of in landfills and incineration facilities and pollution to the environment. To reduce the environmental impacts and embodied carbon of manufacturing new materials and products. To delay the need for new landfill facilities that are often located in frontline communities. To create green jobs and materials markets for building construction services.
CONTRIBUCIÓN
Typical installation results in less than 3% of panels discarded. Panel scraps may be acceptable in mixed-glass recycling facilities. Plastic buckets containing wet materials are recyclable or reusable. Unused panels and bucket materials can be saved for future projects.
