The mission of the GREENGUARD Environmental Institute (GEI) is to protect human health and improve the quality of life, by enhancing indoor air quality and reducing people’s exposure to chemical agents and other polluting substances.
GEI certifies products and materials with low chemical emissions and provides a resource for the choice of healthier products and materials for interior environments. All of the products certified must satisfy rigorous standards of chemical emissions on the basis of criteria established by the most important public health agencies. The GREENGUARD certification is widely recognized and accepted by sustainable construction programs and by building regulations worldwide.

All Quarella products are Greenguard Gold certified. This certification was instituted by GEI to address the indoor air quality needs of schools, daycare centres, and other sensitive environments and, as such, enforces stricter chemical emissions limits than the original certification.

LEED (Leadership in Energy and Environmental Design) is a voluntary international green building rating system used in more than 165 countries around the world, that guarantees a third party certification to a building or community that has been designed and built by adopting strategies aimed at improving performance in fields such as energy saving, water efficiency, reducing CO2 emissions, internal environmental quality and resource management.
V4 is the latest version of LEED and with regard to construction materials it has evolved with a paradigm shift which embodies: life cycle analysis, environmental product declarations and ingredient reporting. These improvements facilitate making data-driven choices which is essential for building performance and occupant health issues.

While the LEED certification considers the building, not the product, it is easy to understand the fundamental role each material plays in obtaining the final score. All products involved in the project can contribute to achieve credits if they meet the requirements.

Quarella is able to contribute with its products – for those who wants to obtain a LEED certification for their project – in the following LEED categories : Integrative Process, Material and Resources, Indoor Environmental Quality, Innovation.

WELL Building Standard™ is:
– a performance-based system that explores how design, operations and behaviors within the places where we live, work, learn and play can be optimized to advance human health and well-being.
– a flexible building standard which represents the future of design; It’s the first rating system to focus exclusively on the impacts of buildings on human health and wellness.

WELL Certified spaces can help create an environment that can improve efficiency, mood and sleep patterns.

WELL Building Standard can be applied in many real estate sectors.
The certification establishes the performance requirements in ten categories, or concepts, related to occupant health and well-being in the built environment: Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, Community.

Projects that pursue the WELL certification are evaluated on the points earned in the different categories specified above. Based on the number of points obtained, a project receives one of the three WELL rating levels: Silver, Gold or Platinum.
